Kazuhira Miller

"The world calls for wet-work, and we answer! No greater good... No just cause!"

- Kazuhira Miller

Kazuhira "Kaz" Miller (カズヒラ・ミラー), also known as McDonell Benedict Miller and Master Miller, was the subcommander of both the Militaires Sans Frontières and Diamond Dogs, and was the survival trainer of FOXHOUND. He was well-read and possessed a vast array of scientific knowledge.

Early life
The child of an American GHQ officer and a Japanese woman, Kazuhira was born in Japan, during the country's occupation by U.S. military forces, and was named after the Japanese word for "Peace" ( 和平 ) by his mother. Kaz was conceived as a result of his mother working as a prostitute, though his father treated her as a wife. Kaz's early life in Japan was a struggle, as he was born after his father had returned to America, and could not obtain Japanese citizenship due to his father being unknown. Many Japanese children would often mock him for his Western appearance, with his blue eyes, blond hair and fair skin. Because of these factors, he identified himself more with the United States, the winners of World War II, than to the Japanese. However, his father had left his mother some money prior to leaving, which she used to set up a shop, selling items such as cigarettes to occupation troops.

When Kaz was ten years old, his mother became ill, leaving him to run the shop by himself. While his mother was bedridden, he stumbled upon a picture of his father, and began showing it to the American soldiers who came into the store, asking if they knew who the man was. He eventually learned from one of his father's students that the man was Colonel Miller, who had retired from active duty and was serving as a military instructor. Kaz knew he wanted to go to America as well as meet his father, so he eventually sent a letter to him in the U.S., requesting to travel there.

That wish was eventually granted and Kaz was picked up from his home, left his mother behind, and went to the U.S. to get an education. Kaz soon discovered that he once had a half-brother, though he had recently died in the Vietnam War, which had caused his father to enter a state of depression. Taking on his father's surname of "Miller", Kaz was supplied with money to enroll at an Ivy League school, later graduating from it and receiving his college degree. During his stay in America, he also witnessed the rise of the anti-Vietnam protests that were occurring within America. He then returned to Japan, only to find that his mother wasn't angry that he had left her behind, but that she had simply forgotten who he was entirely, her mind having been affected by a disease she contracted during her days as a prostitute. Shortly after returning, he joined the Japan Self-Defense Forces, both to pay for his mother's hospital bills, and also as a way for him to get a taste of the battlefield.

Unfortunately for Miller, life in the JSDF wasn't as glamorous as he had hoped. His skills as a policeman were unmatched, but his superiors often feared them and chose not to reward those skills, so he didn't rise through the ranks as quickly as one would expect. Furthermore, he longed for a more active battlefield than what life in Japan typically offered, and by 1970, he decided to leave the JSDF, especially after witnessing The Temple of the Golden Pavilion author Yukio Mishima's coup d'etat and suicide at the JSDF Headquarters. He returned to America, only to learn his father had committed suicide, and was already buried. After his mother died, he began to drift around the world as a mercenary and a well known philanderer who loved the freedom of the '70s.

First encounter with Big Boss
Miller's travels eventually led him to Colombia, where he got himself a position as a drill sergeant for a band of revolutionaries, despite never having seen a day of combat. It was during this time that he gained the name "Master Miller." Two months later, he and his guerillas fought against the current Colombian regime, but they ended up caught in an ambush. Being inexperienced with actual combat situations at the time, he ended up sending a soldier to act as bait (and denying it when accused of such) and then fled. He ended up caught in an explosive booby trap, injuring him, although not before killing several of the opposition.

In the aftermath of the battle, he met the enemy commander, Big Boss (Naked Snake), who was fighting for the government forces. Big Boss attempted to get him to surrender, although Miller claimed he wasn't able to show his hands, with Big Boss seeing through it and informing Miller that his men were dead. Miller then mentioned that he came all the way from Japan as his place was on the battlefield, and requested that Big Boss act as his kaishaku (executioner for dishonored soldiers). However, Miller had actually intended to distract Big Boss to pull his trump card: Miller prepared to take his own life with a grenade and ensure Big Boss died with him as a last stand. However, Big Boss managed to prevent Miller from committing this action by preventing him from removing the lever. Miller then ended up falling unconscious, although not before declaring that Japan won't lose again. Big Boss was impressed with his spirit, likening it to that of a samurai, and had him recovered from the battlefield and placed in a field hospital tent at the government soldiers' base to recover.

After Miller regained consciousness and discovered he was in a tent, Big Boss arrived to talk with Miller. Miller, however, did not wish to talk to him, due to being his enemy. Big Boss revealed that he had not come to interrogate him (he in fact already found out who Miller was shortly beforehand), nor did he come to request that Miller join the Colombian government soldiers: Instead, revealing he was himself a mercenary like Miller and he had in fact completed his paid assignment with the defeat of Miller's unit, he intended to convince him to instead join the Militaires Sans Frontières. Miller, however, did not intend to join Big Boss, especially when he was still his enemy. Big Boss then listed the alternatives: He could let Miller be handed over to the Colombian army, where they would interrogate him with a bamboo manicure (as Big Boss trained them in interrogation himself), and then end up executed; he also can't return to the Guerilla forces he led due to CIA-laced rumors being spread that Miller had been a government agent sent to sabotage their efforts from within, and thus would probably end up executed by his former forces; and there's little chance of him escaping Colombia, either. Big Boss also relayed that if Miller were to cooperate, he could ensure Miller received a pardon from the base's commander, and explained to Miller his philosophy about how soldiers like him are to fight on the battlefield constantly. Miller, while not agreeing to join, decided instead to hold a contest to determine whether he should actually join him, as he doesn't want to admit defeat. Big Boss agreed, under the condition that Miller not try to escape as the soldiers are temperamental at the base. In actuality, however, Miller's "contest" was a ruse for an elaborate escape attempt, as well as a means to convince Big Boss to join him in fulfilling his own dream of a new form of business.

To this end, Miller had a local peddler, Miel, deliver a letter to his elite soldiers (who weren't present at the battle) listing a plan to ambush Snake and his men at sundown in a specific, Drug cartel-owned area of the jungle, also giving the signal by loudly shouting the final event. Miller and Big Boss then conducted their contest events (knife-fishing [originally spear-fishing, before Big Boss suggested to use knives instead]; arm wrestling; fast gun assembling [which was done blindfolded after Miller bragged that he was the fastest one while in the JSDF]; eating the Arowana they caught earlier the fastest; and speed-shooting), with Big Boss beating Miller every time to an extent that Big Boss made it easier for Miller by stating that he only needed to win one event to ensure his freedom. However, during the final event after Big Boss went, Miller's guerillas came into position and surrounded them. Miller then explained his goals and tried to get Big Boss to join him, not wanting to be subservient to Big Boss. However, Big Boss refused, and ended up quickly disarming Miller with his field-strip (which one of Big Boss's soldiers had earlier warned him of this by mentioning that he'll pull his "broken gun trick" if he tried it). To make matters worse for Miller, his own soldiers ended up restraining him instead of Big Boss and his forces reluctantly. Big Boss then admitted that they joined his forces due to Miel showing him the letter Miller sent earlier before it reached its destination, and he met with them as a result, convincing them to join just by sitting down and talking.

Humiliated once again, Miller left for the forest alone, declaring he'll make do with himself if that's what he can do. Big Boss, however, pursued him, both because he knew he wasn't well equipped to deal with the bandits in that area at night and still hoping that he'd join MSF, and eventually got into a fight with Miller, eventually slamming him down onto the ground. Miller eventually accepted joining MSF, deciding he'll at least fulfill his dream that way, although he makes clear he hasn't lost yet and will hold the contest again in the future for real. However, while making small talk about themselves, Miller and Big Boss were ambushed by some bandits, although Big Boss subdued them and slammed them into the ground. They then made their way back. Years later, Miller would tell Big Boss that he didn't realize until he met him that "there's no such thing as an absolute enemy. Our enemies are always relative." Miller would later play a vital role in the management of the MSF and supported Big Boss during his missions in Colombia.

In November 1974, Miller brought Paz Ortega Andrade and Ramón Gálvez Mena to the MSF camp on the Barranquilla Coast, after making sure that they weren't being followed by "their 'friends' from Langley." Gálvez wanted to hire Big Boss and the MSF to repel a security company that had recently entered Costa Rica. Unlike Big Boss, Miller didn't really feel that the deal was a bad idea, especially with the offer of an offshore plant in the Caribbean to use as a base of operations (as their current base was in disrepair), although he became reluctant upon learning that Gálvez was a KGB agent. Big Boss eventually agreed to take Gálvez's offer for Paz.

From their "Mother Base", Miller provided radio support to the MSF forces as they entered Costa Rica. Big Boss contacted Miller from a nearby shipping facility, noting the unusually large amount of radiation film badges located there, and the radioman that he had previously interrogated having mentioned something about "spears" being delivered in the cargo. Miller and Big Boss then realized that this could mean only one thing: nuclear weapons were being shipped into Costa Rica, something that Miller found horrifying.

Miller then suggested that they ally with the local Sandinistas that had been ousted from Nicaragua, to help in tracking down the supply route to the facility in Mount Irazu, and gave a status update on Mother Base's repairwork. Metal Gear Solid: Peace Walker, Kojima Productions (2010). Kazuhira Miller: How's that map, Snake? Think you can use it? // Naked Snake (Big Boss): It tells me where their bases are, but its just a bunch of points. No routes. I need better intel on the lay of the land. // Miller: Snake, the "professor" said he's got the Sandinistas on his side. Said you should get in touch with the FSLN comandante. // Snake: Do they know they're backed by KGB? // Miller: Nah... As far as they know they're really fighting for the revolution. The KGB is staying behind the scenes. I'm not sure the Sandinistas are aware of what's really going on. // Snake: Still can't believe anybody'd bring nukes here... // Miller: Yeah, that's a shocker. Costa Rica's party to the Tlatelolco Treaty, which declares Latin America a nuke-free zone. Based on Japan's Three Non-Nuclear Principles, it bans the testing, use, import, or deployment of nuclear weapons. If word of this gets out, OPANAL will be forced to act. It'll cause an international uproar. //Snake: The Treaty was signed to prevent another Cuban Missile Crisis. If the U.S. itself is going to scrap it... // Miller: Latin America's too close to spawning another Cuba or two already. The entire continent would become one big powder keg. // Snake: Well... If they did bring nukes, we can't let them get away with it. // Miller: Are they planning a test? Showing off? Or is it all to keep the anti-American movement in check? // Snake: Good Question. Why bring them here? I can't figure it out. // Miller: Whatever the CIA's up to in Costa Rica, the "professor" wants it stopped. We need to find out what that something is. // Snake: We need to get ready first, Kaz. Repairs? // Miller: Working as fast as we can, Boss. This place is pretty beat... It looks like hell. But as long as you're with us, we'll make it heaven. No one can bother us here. No state telling us what to do. This is the MSF's haven, our Mother Base. And with this foothold, we'll back you up even better than before. We're gonna turn this pile of junk into something big. Meanwhile, he and the MSF refurbished Mother Base, personally suggesting to Big Boss that he be assigned anywhere on the base's staff that needed assistance, citing MSF's small size. Despite Big Boss's view that being second-in-command was good enough, Miller did not want feel as though he was just "sitting around." In addition, he also rigged Big Boss's radio so that he could contact Paz while she was hiding at Ciudad Colon. The revelation of an unmanned weapon during the interrupted meeting between the FSLN and Big Boss had Miller reacting with shock at the presence of a weapon he only heard rumors about, and agreed with Big Boss to have FSLN comandante Amanda Valenciano Libre followed, as she's the only person besides the then-recently deceased Sandinista Comandante who can confirm whether or not the CIA group did have nukes in the region. Miller later had FSLN comandante Amanda, her brother Chico, and French citizen Cécile Cosima Caminades extracted from Costa Rica, after Big Boss made contact with them.

Miller continued to propose ideas for the expansion of MSF, including the adoption of a Mess Hall Team, a Medical Team for Mother Base's sick bay, an Intel Team, outside operations, and voluntary recruitment. He also coined the phrase "Pooyan Mission" for operations that involved preventing enemy usage of Fulton recovery, named after a pet pig belonging to neighbors of his, during childhood. With Amanda in crutches due to her injuries, Miller initially attempted to stop her from leaving Mother Base's sickbay, citing concern for her wanting to return to the battlefield, only for Big Boss to point out that she wanted to do so for her comrades, and suggested letting her out of sickbay for the time being as it was also beneficial to MSF's development. In addition, after AI weapon researcher Dr. Huey Emmerich defected to the MSF and was assigned to the R&D Team to develop a bipedal tank, Miller discussed the possibility of the weapon's name, and the two came up with "Metal Gear ZEKE." Miller believed that MSF would need ZEKE as a deterrent against other countries, in order to achieve true independence.

Big Boss and Miller eventually learned that Hot Coldman, the CIA Station Chief of Central America, was the one behind the invasion and the Peace Walker Project, although Big Boss ended up captured shortly after a failed second-attempt to destroy the Mammal Pod. During Snake's capture, Miller attempted to contact Snake in vain, explained to a concerned Amanda that there was one thing Big Boss would never allow the Peace Sentinel to confiscate from him (referring to the jigsaw that Big Boss had on his person that he disguised as a scar that was a copy of The Boss's scar), and also had MSF forces aid Big Boss by retrieving his equipment so they can give it back to him when he escaped. In addition, Miller, noticing that he couldn't get into contact with Paz, had an MSF member sent to the school at Ciudad Colon, and discovered from the soldier that while the school itself did exist, Paz and Gálvez were not seen in the school for quite some time, and later relayed these details to Big Boss as soon as the latter escaped from the prison.

However, neither Big Boss nor Miller had known that Coldman was planning on using Peace Walker to launch a nuke towards Mother Base, namely to poison the fish and crops so that mass production could begin, but also to annihilate the MSF. When they learned this, Miller stated that Big Boss had to stop Peace Walker from arriving in Nicaragua. However, after that had failed, he considered evacuating Mother Base, but decided against it as the personnel believed in Big Boss. He did, however, prepare a backup unit in case Big Boss was unable to stop Peace Walker at the U.S. Missile Base in Nicaragua.

Later on, Miller arrived with the majority of the MSF forces into Nicaragua to aid Big Boss in stopping Coldman's plans. After joining forces with Amanda's FSLN group, they took down the Peace Sentinel, arrested Vladimir Zadornov (Gálvez) and Coldman. Miller also lectured a distraught Paz in not picking up a gun unless she planned to use it. Miller discovered that Coldman activated Peace Walker, and not only was it going to be launched at Cuba (as Zadornov had changed the target earlier), but it would also transmit false missile trajectories to third parties all over the world, including NORAD and the Pentagon. He alerted Big Boss and Strangelove about what happened, with Coldman dying before he could give the abort code (a factor Coldman had taken into account), forcing Big Boss and Strangelove to destroy the Peace Walker unit.

After the fiasco ended, Miller teamed up with Huey and Strangelove to build Metal Gear ZEKE, which was created from the prototype weapons of the Peace Walker Project. He also arranged for Peace Walker's nuclear warhead to be fished out of Lake Nicaragua, both to avoid causing another conflict for the natives, and to provide MSF with a possible nuclear deterrent. After some thought, Big Boss accepted Miller's proposal to install ZEKE with the warhead.

When Paz came to stay aboard Mother Base, Big Boss tasked Miller with keeping an eye on her. However, when Miller attempted to shield Paz from the crude atmosphere of one of the MSF's monthly birthday parties, he failed after becoming drunk himself and began mooning everybody, saying that they should see "the real Kazuhira Miller."

Miller once delivered a package to Big Boss from EVA, after having it checked for explosives. Upon learning about Big Boss's former ties to EVA, he speculated that the two had been lovers, and warned that his commander not get "distracted" by her at the expense of MSF.

With Zadornov in MSF custody, Miller considered recruiting him into the group in order to boost the other Russian members' morale. However, Zadornov's numerous escape attempts from Mother Base forced him to change his mind against it.

At some point during the Peace Walker Incident with the development of Mother Base, Miller had created a sauna on the base, to boost the morale of the Finnish personnel as well as it being viewed as economical. However, he let his womanizing side get the better of him, with him committing "soap play" with one of the female MSF soldiers, Swan, causing her boyfriend Armadillo to faint in shock at Miller and Swan doing this, resulting in Armadillo being sent to the infirmary for a month. Big Boss eventually deduced what happened after interviewing Gazelle, who was a witness to Swan and Miller's actions and being one of the women Miller slept with. In addition, Miller had scratches on his body which implied that Swan scratched him while having sex. Big Boss then reprimanded Miller for his recent behavior due to it setting a very bad example for the personnel, resulting in an argument that escalated into a full-on brawl in the area, which several MSF personnel, including Paz, witnessing it. As a result of Miller's actions, he was sentenced to cleaning up the sauna for a whole year, apologizing to all involved in his womanizing, and being warned to be more careful about his womanizing nature.

After Zadornov escaped captivity for the seventh and last time, Big Boss warned Miller that he must have had "an accomplice" given his final words. Miller then noticed that ZEKE had begun to move on its own, implying that someone had hijacked it, and noticed that Paz was acting strangely. Paz then revealed that she was really Pacifica Ocean, a Cipher agent. After ZEKE was disabled and Pacifica was defeated, Miller wondered "which was the real Paz and which was the lie." Miller later apologized to Big Boss because the former knew what Paz and Gálvez had been up to all along, and in fact was in on their plot, but didn't tell Big Boss sooner. Miller had secretly been acting as a business partner to Cipher (Zero) in order to expand MSF, due to his belief that the mercenary business would become a new driving force in the world economy after the Cold War's end, considering himself nothing more than a business partner, and thus neither an ally nor an enemy of him. In addition, he had earlier leaked news of Paz's modifications to Zero before she had a chance to lie about her progress. However, Zero ordered Paz to launch a nuke at the East Coast, to frame the MSF as being an extremist cult should Big Boss refuse to rejoin Cipher, and thus would jeapordize any chances for MSF expanding.

At some point, Miller examined UFO photos given to the press by Sir Eric Gairy, prime minister of Grenada, and stumbled upon an image of the Chrysalis AI weapon, which he then reported it to Big Boss. Big Boss revealed that he had taken the photo and given it to Chico, which he had then sold to a magazine. Speculating that the CIA was involved in recent incidents of cattle mutilations and abductions across the Americas, Miller expressed concern at Gairy's attempt to have the UN investigate the "UFO problem," believing that he may be "digging too deep" and would get himself into trouble.

Side ops
Afterwards, Miller had MSF take various jobs, with Big Boss participating in the missions in person.

On December 3, 1974, at 13:18, Miller and MSF were hired to neutralize an infamous sniper duo who made their mark during the Laotian Civil War as part of a request from the KGB backers Miller had earlier been acquainted with. Miller relayed this aspect of his past to Big Boss, although he made clear that the KGB contacts had no connection whatsoever to Zadornov beyond common KGB affiliation. He also relayed information about the targets, including that they killed innocent civilians, and that their extradition to Laos to stand trial was in the talks for the peace negotiations. After the mission was completed, Miller noted that the two soldiers had been afraid of something even more than that of death itself, causing him to become suspicious of the base they had just infiltrated, Camp Omega. He later had an Intel Team agent infiltrate the base to investigate.

On December 7 at 05:31, one of MSF's Intel Team agents, Hideo, requested an extraction from his assigned location, Camp Omega at the Naval Prison Facility in Cuba, with Miller arranging for him to be retrieved as he was vital to MSF's operations. As they had little time to do the stealth approach, Miller told Big Boss to assault the base. He also relayed orders to the pilot of the Hind chopper that Big Boss used to extract the agent, Hideo. Miller expressed impressment at Hideo's resourcefulness and skill in hijacking and driving a jeep.

On December 21 at 18:08, Miller had Snake return to Camp Omega to retrieve a classified intel from an undercover agent planted at the facility. Their client hired them via a cutout to retrieve the intel, although Miller suspected their client was the Joint Chiefs of Staff, especially as their Chairman owed Snake for his actions in quelling the Peace Walker Incident. As they couldn't risk blowing the DOD mole's cover, they instead had to directly interrogate him. Miller, however, became suspicious of the agent's storage location in the central control tower and warned Big Boss to be careful. True to his suspicions, Big Boss overheard the agent and a bald Marine talk about the central control tower being a trap The cassette tape was placed near a surveillance camera. Big Boss managed to escape with the intel on both the tape from the tower and the actual tape that he took from a bald Marine. The first tape contained information on a Cipher agent known only as Skull Face. They also analyzed the tape and deduced it to be an interrogation, thus providing undeniable proof that it had been converted to a blacksite. In addition, analyzing the other tape, which had been the true target, supplied a full plan for the black site, making it more apparent the base's black site status, though Miller wondered whether this was the "world without borders" that Cipher alluded to.

Sometime afterwards, Miller, suspecting Cipher's involvement and deciding to get a lead on them, secretly dispatched an Intel Team agent to the base to uncover information. Unfortunately, this decision ended up resulting in the agent's capture.

On January 9, 1975 at 07:01, Miller and the MSF were hired by the United States military's Joint Chiefs of Staff to sabotage one of their own base's anti-air emplacements, as they were preparing a MAGTF to retake the base. Miller guided Big Boss through the mission, informing him to take out three of the four AA guns. He also admitted that he had secretly sent an agent to the base, but he had been captured, and after apologizing for not telling Big Boss earlier, requested that he save the agent, provided he was still alive, as well as informed him that there were several other moles belonging to the DOD who had been captured, and that the U.S. Government unofficially supported the JCS's mission due to it causing a negative diplomatic disaster had the base been uncovered. Shortly after Big Boss infiltrated the area and placed a C4 package on an AA gun, Miller reported that the base had undergone a full alert due to the base's defense systems detecting the amphibious assault carrier containing the MAGTF sooner than expected. After all three were destroyed, Miller told Big Boss about an APC with a cannon that would prove to be a threat to the MAGTF choppers, requesting that Big Boss destroy it. Afterwards, Miller was about to send the extraction chopper, but then noticed an unexpected development on Mother Base's radar: Two unidentified aircraft were headed towards the base, and their speed exceeding the 500 mark made clear they were attack aircraft. Disturbed by the timing of their discovery, Miller told Big Boss to get out of the premises, also informing him they were non-friendly after the MAGTF was shot down by the craft and identified their payload as being bombs, meaning the aircraft were going to do a bombing run on the camp. After Big Boss rescued the moles and Intel Team agent and managed to escape (witnessing the destruction of the blacksite during the escape in a bombing run), Miller was nonetheless satisfied that they fulfilled their end of the bargain despite the unexpected ending to the mission. During the debriefing, Miller revealed that the aircraft were of western origin, meaning someone within the United States didn't want the black site discovered and manipulated everything to ensure that it was kept secret. Miller then voiced suspicion that the person or entity responsible for the attack, although unconfirmed, was most likely Cipher.

Inspection preparations
In February 1975, the MSF received a request for an inspection from the IAEA. Officially, the reason was because they received a shipment of nuclear fuel from Uzbekistani officials, although both Miller and Big Boss knew that this was actually done under the influence of Cipher, as revenge for their earlier defeat and Paz's earlier leaks. The two attempted to write an official letter of refusal explaining that they were a private firm, Metal Gear Solid V: Ground Zeroes, Kojima Productions (2014). Info > Pre-mission Brief: Mission Background & Intel > Brief 1: Nuclear Inspection demand by the IAEA Kazuhira Miller: Snake, yesterday we received official communication from the IAEA. It says: “It has come to our attention that your organization recently purchased nuclear fuel from Uzbekistan authorities. We request permission to inspect your facilities.” // Naked Snake (Big Boss): What a load of bullshit. // Miller: Yeah. They’re after Metal Gear ZEKE’s nuclear warhead. I’m betting this is payback from Cipher after Paz’s leak. // Big Boss: Using the UN? // Miller: There’s no telling how much influence they have. But the IAEA can only do inspections in countries that are partied to the NPT. // Big Boss: And we’re not a country. // Miller: Exactly. We haven’t signed a safeguards agreement with the IAEA over peaceful nuclear use, and we’re not obligated to report any nuclear material we have, nor information about any nuclear facilities. The IAEA has no authority to inspect us. // Big Boss: But despite all that… // Miller: That nuke’s our last line of defense. We don’t want to announce we have it until the world is preparing to wipe us off the map. Until then, we let everyone think we’re just a private army with conventional firepower. // Big Boss: What’s Huey’s take? // Miller: That the problem’s how to hide the nuke and Metal Gear. But I gotta tell you, he was all for it. // Big Boss: I see... But there’s no way we can have the IAEA poking around here. // Miller: So what do we do? Ignore 'em? // Big Boss: Send them an official letter of refusal. Say we’re a private organization and we’ve done nothing to attract this suspicion. // Miller: You’ve got it. but Huey, one of the few actually supporting the inspection, ended up sending a letter that indicated that MSF changed their minds and accepted it. Now with no other options but to allow the UN inspection to come about with media coverage by at least two major western networks, Miller ended up relocating all AFVs save for Metal Gear ZEKE to shore, and have troublemakers go with the vehicles for some mandatory "R&R." Metal Gear Solid V: Ground Zeroes, Kojima Productions (2014). Info > Pre-mission Brief: Mission Background & Intel > Brief 2: Allowing the Nuclear Inspection Huey Emmerich: We’ve finished ZEKE’s waterproofing reinforcement yesterday. The day after tomorrow, we’ll be done installing the main depth control tank, the compressed air tank, and the attitude control propeller pod. // Kazuhira Miller: Huey… // Huey: If the underwater test goes well, next week we’ll try the 300 ft. seabed depth. // Miller: Drop the act, Huey. How did we end up agreeing to the nuclear inspection? // Huey: …Because after you sent that letter, I told them “after careful reconsideration, we’ve agreed to your request.” And frankly, we should be inspected. This is our chance. If they come and go without discovering the nuke, we can tell the world we’re clean. Of course, it’s risky, and we’ll have to make sure everything’s perfect, but it’ll be worth it. // Big Boss: Huey, can they do an inspection without going through the Board of Governors? // Miller: We contacted the IAEA’s admin branch, and they said there’s no record of us being brought up at any of the board’s meetings. Huey: I’d say... probably a preliminary inspection to determine whether we should be referred to the board. So it’s bound to be a small inspection team, and they won’t be here that long. Don’t worry, leave everything to me. // Big Boss: Has the media gotten wind of this? // Huey: Yeah. Two major western networks want to do stories on us. I planned on saying yes. // Miller: What?! You want to broadcast this place to the world?! // Huey: That’s why I agreed to the inspection. This is a golden opportunity. We can use the media to “prove” to the world we don’t have a nuke. Besides, even if we said “no,” it would just be delaying the inevitable. // Big Boss: (groans in irritation) Kaz, our hands are tied now. Start getting the place ready. // Huey: Thanks, boss. // Big Boss: Don’t get the wrong idea. You set it up so that any more changes of heart would arouse suspicion, that’s all. Heh. // Miller: ZEKE stays, but we’ll have to move all other AFVs to shore. Any potential troublemakers can go with them for some mandatory R-and-R. Sound good, boss? // Big Boss: Just do it. He also informed the remaining MSF members the truth relating to the UN inspections to ensure they don't inadvertently reveal ZEKE's existence. He also arranged for Amanda to house her fellow FSLN troops at Cuba due to her being stationed there at the time, and the presence of soldiers that were technically Soviet-bloc would leave a bad impression on MSF. Except for Huey, all civilians were evacuated from Mother Base, including Cecile, where he prepared her papers so she can return to Paris. Miller also admitted that he had Strangelove retired from MSF due to the AI development program not accomplishing much as well as ZEKE being completed anyways while Big Boss was on a mission the prior week.

Rescue mission at Camp Omega
Ten days later, Miller relayed reports that Paz had survived her fight with Big Boss and was rescued by a fisherman when she lay adrift in the Caribbean. He later planned a rescue mission to retrieve Paz who was detained by Cipher on the Cuban prison facility Camp Omega under suspicions of her allegiance being compromised as she was the only viable link left for MSF to track down Cipher and find out their plans and also to find out "what she really thought of them." Miller found out about Paz's capture from information supplied to them by Amanda. They initially planned to delay rescuing Paz until after the inspection, and had Chico moved to Cuba to distract him by having him meet his sister there. Metal Gear Solid V: Ground Zeroes, Kojima Productions (2014). Info > Pre-mission Brief: Mission Background & Intel > Brief 4: Word of Paz's Survival Kazuhira Miller: Ten days ago, we got reports that Paz was still alive. // Big Boss: She survived? // Miller: She was rescued by a Belizean fisherman who found her drifting in the Caribbean. Big Boss: So what’s the plan? Silence her before we’re compromised? // Miller: No, I’ve got something else in mind. Our “friends” at Cipher suspect Paz could be a double agent. She’s being held for interrogation at a camp on the southern tip of Cuba. // Big Boss: Black site. Nice. A slice of American pie on Communist soil. And out of U.S. legal jurisdiction. // Miller: The upcoming inspection of Mother Base has to be connected somehow. The timing’s too perfect. // Big Boss: The UN’s nuclear inspection… // Miller: My guess is they’re trying to corroborate Paz’s leak. // Big Boss: We’re an army without a nation. // Miller: Word of our capabilities gets out, and we’ll have the whole world out to shut us down. Having an American private intelligence agency involved is bad news. Cipher’s the ones who sent Paz to us in the first place. // Big Boss: She knows their true nature. // Miller: Right. Paz is our only link to Cipher. If she’s still alive, we need her on our side. If not us, who else is going to rescue that bitch?! // Big Boss: When do we do it? // Miller: The inspection comes first. We’ll deal with this afterwards. // Big Boss: Do the men know? // Miller: Word has started to spread. The information came from Cuba through Amanda. One of the base personnel used to belong to el Frente. I’ll tell everyone we don’t concern ourselves with the survival of enemy spies. We need them focused on the inspection. And if we get her back here and she isn’t… cooperative, there’s still plenty of room for her in the ocean. // Big Boss: Works for me. What about Chico. He had a chance to stop Paz from hijacking ZEKE and he blew it. He’s carried that guilt ever since. Kid really did care about her. // Miller: Chico… It’s hard to say how he’ll react. // Big Boss: Have Amanda call him out to Cuba. He shouldn’t be here right now. // Miller: Good idea. They haven’t seen each other in a while. A little time with big sis, and he’ll forget all about you-know-who. However, Chico ended up disappearing from the ship he was assigned to. Miller initially thought and relayed to Amanda as much that Chico must have simply gotten lost in the city, but then realized to his horror after conversing with Big Boss that Chico must have snuck out of the ship while it was refueling at Santiago de Cuba, which was sixty miles away from the prison facility that Paz was imprisoned at, with it being a three day hike due to mountainous terrain. Miller then had the Intel unit dispatch at Cuba try to find him.

They eventually learned that Chico was taken prisoner and received an SOS signal from him which also confirmed the location of Paz in the same facility, with the Intel unit also confirming Chico's account. Big Boss volunteered to take the mission to retrieve them, resulting in Miller holding down Mother Base for the inspection. He briefed Big Boss on the details of the military base Chico and Paz were held at, and also stated that while Chico must survive and escape, Paz can be killed if no other option is left, as well as stating that it was impossible to escape the base on foot due to mines. Miller also briefly implied that he only wanted to save Chico to prevent him from talking as he knew too much about MSF, earning a rebuke from Big Boss. Metal Gear Solid V: Ground Zeroes, Kojima Productions (2014). Info > Pre-mission Brief: Mission Background & Intel > Mission Intel: US Military Base, Cuba Kazuhira Miller: Snake, you can forget about civil liberties where you’re headed. God only knows what they’d do to you if you get caught. Do not let that happen. The Cubans leased the land to the U.S. as a gesture for helping them gain independence from Spain. The deal remains in effect until both countries agree to dissolve it or the U.S. abandons the land. That’s why America still operates the base even after la revolucion. Problem is, it’s leased land. // Naked Snake (Big Boss): Meaning it isn’t American soil, so the U.S. constitution doesn’t apply there. That allows them to withhold its civil rights protections. // Miller: Yeah, that’s Uncle Sam’s excuse. The area was originally only for detaining refugees from countries like Cuba and Haiti. But a few years ago, the CIA and it’s like started using it as a black site. Enemies of the State are renditioned there and subjected to extreme forms of interrogation. You can bet Cipher had a hand in that. As you’d expect, American and other Western human rights organizations aren’t allowed anywhere near the place. What happens there disappears down the memory hole. // Big Boss: Who knows what they’re doing to Chico and Paz. // Miller: I’d like to interrogate her ourselves, but if worst comes to worst, make sure she’s dead! Chico on the other hand we have to bring back – fast! He knows too much about us… // Big Boss: Kaz! // Miller: The area’s surrounded by mines placed by both the U.S. and Cuba, making escape on foot impossible. You’re heading into the lion’s den, Snake. Don’t take this one lightly. Come back in one piece. // Big Boss: Yeah. Because of their current situation, they could only afford to send no more than one extraction chopper to Big Boss once he has gotten Chico and Paz, although both also noted that the one silver lining was that, because of the stormy weather near Cuba on the day of the mission persisting until sunrise, Big Boss can easily infiltrate the base due to the inclement weather acting as cover. During the mission, in addition to hosting the UN inspection, Miller monitored the situation and gave advice to Big Boss when needed. 40 hours after Chico lost contact with the MSF on Camp Omega, Big Boss was dispatched to Chico and Paz's last known location: an old area of the facility, while he and the rest of MSF will deal with the nuclear inspections by the UN that were implied to have been sent by Cipher due to Paz's earlier leaks about their possessing a nuclear weapons program. Miller alongside the other MSF members ended up informing Amanda about Chico's current status, with Amanda telling him that, as Chico was her younger brother, she'd know if Chico was lying, and with that said, she was "ready for the worst." He also expressed some disturbance about Amanda apparently being elated about her "readiness."

XOF Trojan Horse operation
As Big Boss returned to Mother Base with both Chico and Paz, Miller heard an explosion and went to investigate. Miller and the MSF were soon caught in a surprise attack by the military group XOF, which had used the UN inspection as a "trojan horse." Miller had been wounded by the time Big Boss arrived back at base, and was evacuated to a helicopter with the help of his commander and another soldier. Escaping at the last second before the strut sank into the ocean, a furious Miller informed Big Boss that the UN inspection had been a smokescreen, and proceeded to interrogate the injured Paz, largely out of anger at MSF's recent losses. Startled awake, Paz coughed up blood in his face and rushed away from him. She then opened the door of the chopper and sacrificed herself by jumping out, knowing that a bomb implanted inside her body would detonate at any moment. However, she was unable to fall far enough for the helicopter to avoid damage from the explosion's shockwave, and it was sent spinning into the path of another chopper.

Miller, Big Boss, and an MSF medic were hospitalized in the aftermath of XOF's attack, with Miller himself suffering lacerations to his face. He was informed that Big Boss had been resuscitated, although the time take to do so caused him to fall into a coma. Miller then asked about the status of the medic.

He also bore somewhat of a grudge against Huey, due to the latter's role in the XOF attack. He also was supplied with funding regarding Diamond Dogs by the ailing Zero, as an apology for Skull Face and XOF's attack on Mother Base and the MSF. He also lost contact with Strangelove, although he knew that she had made contact with Amanda regarding Peace Walker in Lake Nicaragua before he lost contact.

Diamond Dogs
Miller and some of the other survivors of MSF eventually reformed as the Diamond Dogs. During the nine years Big Boss was in a coma, Miller spent his time training various dissident soldiers. In 1984, Miller was training some Mujahideen soldiers in Afghanistan during the Soviet invasion, but he and his unit were ambushed by the Parasite Unit, which eventually resulted in his capture and torture by the Soviets, and the rest of his unit was killed. Before his capture though, he told Ocelot to seek out "Big Boss" at the hospital, both to rescue him from a similar attack, but also so he could save him. While in captivity, he lost his right arm and left leg. Miller was later found in a prison by Venom Snake, who helped him to escape the country.

The attempts to destroy MSF, combined with the suffering endured during captivity, made Miller extremely vengeful towards Cipher, more specifically XOF and its leader Skull Face. and obsessed with its destruction. Although he wanted Diamond Dogs to be based in Latin America over Seychelles, he ultimately accepted the latter, as Latin America was doing fine under Amanda. Ocelot also suggested that he get some Soviet-made prosthetics to replace his lost limbs, although Miller declined, both because he didn't care for his limbs anyhow, and he wanted to at least live with his phantom pain until his comrades were properly avenged.

At some point after their new Mother Base received extensive expansions, one of their forward operating bases ended up invaded by a competitor. He later notified Big Boss of this as soon as he returned upon receiving the news, and requested orders from him in a way that made clear he was very eager to find the intruder and teach the intruder and whoever the intruder worked for a lesson.

Ultimately, he and Venom Snake eventually find Skull Face after he was gravely injured from ST-84 going haywire due to Tretij Rebenok going mad from Eli's presence. Miller and Snake considered killing him right then and there but they chose not to, deciding instead to shoot off two of his limbs for revenge. They had planned to leave Skull Face to die in agony under the rubble, however, Huey proceeded to kill him shortly afterwards.

During the second parasite outbreak in the Laboratory on Mother Base, once Big Boss could identify those who were infected, Miller urged Big Boss to kill anybody who was infected, as they could neither treat them nor could they allow them to escape and risk spreading the parasite. He later attended the funeral for the personnel that were killed in the incident, believing that their cremated remains would be buried at sea, although Big Boss instead ordered that they be formed into diamonds, which Miller felt would give the soldiers a "light" even after death.

After Miller discovered that Venom Snake was actually just a phantom of Big Boss to act as a decoy on the world stage, Miller gave up on Big Boss in 1984, declaring "he will make his phantom and his son stronger, to send him [to hell]".

Later career
As "McDonell" Miller, he later served as a survival instructor for the SAS, the Green Berets, a U.S. Marine boot camp, and eventually FOXHOUND. He also went on to volunteer as a coach in a mercenary school twice a year before his retirement. During his time as a drill sergeant in FOXHOUND, he was referred to as "Hell Master" and draftees called him "Master Miller" with the utmost respect. It was at FOXHOUND's training camp that he met Solid Snake. Miller also got married to a woman named Nadine, whom he would later divorce. At some point, he fathered a daughter named Catherine, and by 1999, resided in Los Angeles with her.

In December 1999, Master Miller was hired by Colonel Roy Campbell to serve as a survival consultant for FOXHOUND, during the Zanzibar Land Disturbance. Miller thus assisted Solid Snake by radio, providing information on survival techniques, and guidance on how to overcome the various obstacles Snake faced during his infiltration of Zanzibar Land. Such advice included code breaking and finding alternative uses for any equipment at hand, as well as moral support. During Snake's battle with Big Boss, Miller referred to the latter as a "monster" and urged the unarmed Snake to find something to use as a weapon against him.

By February 2005, McDonell Miller had moved to Alaska to live in solitude, in a three story house with his huskies, occasionally helping to train the Alaskan scouts during his free time. However, Miller was murdered in his home by an assassin at least 3 days prior to the Shadow Moses Incident.

Liquid Snake, FOXHOUND's squad leader, then assumed Miller's identity in order to aid Solid Snake in his mission to Shadow Moses, and provided him with information on how to operate within the Alaskan environment via Codec. This disguise also fooled Roy Campbell, the very man that had requested Miller's support in the first place. The truth was later revealed when mission staff member Richard Ames became suspicious, after "Miller" revealed information on Naomi Hunter that not even the DIA were aware of, resulting in Ames sending an agent to his home, and the discovery of the real Miller's dead body. Campbell's Codec link with Miller had also been cut off, though the former eventually learned the truth after Mei Ling traced Miller's signal to within the base at Shadow Moses. Before Campbell could warn him, Snake unwittingly activated Metal Gear REX due to Liquid's trickery, who then mockingly revealed his true identity.

Personality and traits
Kazuhira Miller often wore aviator sunglasses, even in times where sunglasses would not have been appropriate, such as while indoors, at nighttime, while driving during stormy weather, or while showering (although in the last bit, he did note it seemed unusually dark before realizing he was still wearing them ). He had, however, been commented by some female members as being "cute" when he did take off his sunglasses. In addition, Cipher agent Pacifica Ocean said in her diary that he was "actually not that bad looking." He also wore a Rolex watch on his left wrist during his time with the Militaires Sans Frontières. Because of his formerly commanding a guerilla unit prior to joining MSF, his MSF uniform was a modified version of a guerilla outfit, complete with a yellow scarf. Because of his experiences during his youth, he vowed to not allow himself to become a pauper. In addition, he felt he didn't really belong in Japan due to both his lack of a family register, as well as his being mocked by the Japanese children in his neighborhood for his Western appearance during his childhood. He also viewed himself as being a byproduct of war.

Miller was fluent in Japanese, English and Spanish.

During his time as Big Boss's second in command, Miller supplied Big Boss information relating to various factions, such as the FSLN. However, he was known to make mistakes on his analysis, such as when he told Big Boss that the origin of the FSLN's nickname, the "watermelon sellers," was due to their smuggling weapons inside hollowed out watermelons, when it was actually due to General Sandino's nickname sounding similar to the Spanish word for watermelon, "Sandía"; something that Big Boss didn't discover until after a conversation with FSLN comandante Amanda.

Miller was a recording fanatic, which resulted in him suggesting that they reverse-engineer the Walkman prototype that was supplied to them by Paz and Gálvez. He also enjoyed listening to train sounds, although this led to a disagreement with Cécile, the latter of whom expressed disgust at trains, and considered him "less civilized."

Although Miller did ultimately care for the MSF and never discarded his kindness, he was willing to mercilessly use them to his own ends if need be, and was willing to secretly work with Cipher as a business partner in their plan to reinstate Big Boss into the Patriots as long as MSF at was allowed to expand. He later regretted both that decision as well as his earlier hiding it from Big Boss, after learning about Cipher's willingness to eliminate the MSF due to Big Boss's refusal to rejoin.

While Miller was willing to work with Cipher, he only did it to expand MSF. After being saved by Big Boss, he expressed his hatred for everything Cipher has done to them saying that they pull in money and recruits to combat Cipher just for revenge.

Miller was also a trained helicopter pilot, having piloted a Huey over to the U.S. missile base in Nicaragua to aid Big Boss in stopping Coldman's plans, as well as piloting it back to Mother Base afterwards.

Similar to his compatriots during the events of the Peace Walker Incident, including his superior, Miller held a lot of respect for Che Guevara, often discussing him with Big Boss. At one point, Miller supplied Big Boss with the book Guerilla Warfare by Guevara to have him study up on the concept due to wanting Big Boss to be educated on the concept, although Big Boss was unsure whether he ever got around to reading the book.

During his time with the MSF, Miller had a bit of a womanizing problem. On one occasion, he had gone out with two of the female members of the MSF at exactly the same time, causing them to report it to Big Boss. Big Boss then reprimanded Miller for his womanizing behavior, leading to an argument that caused them to get into a brawl in the showers, which Paz ended up witnessing. When recording this event in her audio diary, Paz also implied that Miller's going out with multiple females was a frequent occurrence. Similarly, he attempted to get into a relationship with Cécile due to her status as a blond Parisienne, although their relationship amounted to disagreements, starting with their choice of recording sounds. He also once ordered for Mother Base to be stockpiled with French Wine so they could "drink like they do in the old country" in an unsubtle attempt at impressing Cécile, although this only led to her becoming even more incensed with him, as he picked wine made in 1972, which he didn't realize was a terrible year for France's wine industry. He didn't try to hit on Paz, however, even though he secretly knew she wasn't who she claimed herself to be, implying that he did have some restraint in regards to his womanizing behavior.

However, despite his womanizing personality, Miller was also infatuated with Big Boss, as revealed in one of Paz's reports. While it appeared that Big Boss was unaware of this, prior to their fight in the sauna, however, it was Snake who approached Miller, despite the latter's reluctance. Big Boss also asked Miller to choose between "[the women] or us."

Miller was apparently a very bad singer, as he attempted to give a Japanese lullaby via guitar to an ill Paz, but apparently blew it. His lack of singing ability was referred to later when Paz mentioned that she had to join the band in order to avoid letting Miller be the singer.

Miller's favorite food was curry.

Miller was also knowledgeable on various sciences, of which he later put to use to aid Solid Snake during the Zanzibar Land Disturbance.

Largely because of Paz's betrayal, he held some resentment towards Paz, even remarking at one point, when reflecting on how she hired them, that he should never have fallen for Paz's cover story. Despite this, he was still curious about what Paz's true feelings for MSF were.

Miller also knew about Solid Snake's status as a clone of Big Boss, and was aware of Cipher's plans of using him as an insurance policy, although he never told Snake this. In his later life, Miller was one of the few people Snake deeply respected, as Snake personally admitted that Miller was the only person he would rather have in a foxhole with him. Although he had viewed Big Boss as a friend, he did nonetheless side against him in Zanzibar Land.

He saw Big Boss as a true comrade, as evidenced by his recollection of how they first met: having initially wanted to kill him regardless of himself after Big Boss destroyed his unit in 1972, Colombia. His conversations with Big Boss would vary from teasing jokes to sincere, moving displays of his heart.

After meeting up with Venom Snake in 1984, Miller's personality had changed drastically. While he did have the occasional showing of his old personality, he was significantly angrier in day-to-day interaction due to the pain he harbored after both the XOF Trojan Horse Operation and his torture in Afghanistan. Any failings that befell Diamond Dogs affected him deeply, and he often blamed his own inattentiveness as the cause for them. In large part because of Huey Emmerich's role in the downfall of MSF, he also held a lot of hatred for his former comrade, as he had spent a lot of time trying to track down Huey's location and even used on of his missions with the Mujahideen to locate Huey immediately before he was ambushed by the Parasite Unit. He also worded his intention to meet Huey again when he defected in a way that made clear that he intended to harm Huey once he got his hands on him, and during a torture session also proceeded to bend Huey's leg out of proportion via a magnet as payback for losing his limbs. In addition, he also expressed disgust towards Huey when his crimes came to light shortly after a horrific pandemic of parasites was unleashed and Huey's role was in it, taking the opportunity to show the Mammal Pod as a witness to Strangelove's last moments with incriminating statements towards Huey killing her, and made it very clear that he wanted Huey executed and was outraged when Venom Snake chose to exile him instead. Miller later felt regret for his role in turning Venom Snake into Big Boss's phantom and vowed that he would aid the phantom and Big Boss's clone sons in hopes that doing so would hasten Big Boss's downfall.

The residual pain Miller held on to in the 1980s proved very important to him, refusing the use of advanced bionics (such as Venom Snake's) opting instead for a rudimentary leg prosthetic and walking crutch at the most. He asserted that this decision was so he could remember the pain Cipher had caused him, as a reminder of his desire for revenge.

Miller was shown to have a soft spot for children, as he requested that Venom Snake if he were to encounter any child soldiers in Africa that he not kill them, and he also supported Venom Snake's decision to fake the deaths of The Mbele Squad instead of executing them as planned. He also implied after the conclusion of a mission to extract a child commander and a General's Number 2 that he was willing to forego a paycheck so he would not kill the commander due to his being a child soldier by faking his and the Number 2's deaths. He also made clear that he will not under any circumstances allow Diamond Dogs to use child soldiers, including the then-recently rescued Mbele Squad, opting to instead give them an education and life beyond being a hired gun. In addition, when he learned about how Huey planned to use his then-toddler son Hal Emmerich as a test pilot for the ST-84 Metal Gear, he displayed clear revulsion towards Huey for this act, alongside that of his role in Strangelove's death and his motive.

Unconfirmed history
Prior to joining FOXHOUND, Master Miller had participated in the Vietnam War, and was once placed in a POW camp and interrogated by the Vietcong, although he later managed to escape, "blowing the brains out" of the head interrogator in the process. During his time at the Marine boot camp, he met Roy Campbell.

Between his retirement and death, Miller worked out in his makeshift gym in his basement three hours a day, with one of his exercises including punching his punching bag in order to take his mind off the fact that he was alone in his retirement. In addition, he kept a weapon in every room in case of a break-in, including a Glock 9mm and other handguns behind a clipboard inside the gym. His house was also close to the Canadian border in Alaska. His reasons for moving to Alaska upon his retirement was so he could pursue the subject of studying various Alaskan legends and folklore due to it being an subject he invested a lot of interest in.

In 2005, Miller was murdered in his home by a nerve toxin (which Miller guessed was sevoflurane) after his assassin managed to somehow arrive at his house without a vehicle on treacherous terrain, silence one of his huskies mid-howl, and break the circuit box for the house's central alarm system.

According to Solid Snake, Master Miller was not a talkative type, which Liquid Snake attempted to emulate while impersonating him. However, Liquid exaggerated this characteristic, causing Snake to become slightly suspicious, especially during a conversation regarding Nikita missiles.

Behind the scenes
Master Miller first appeared in Metal Gear 2: Solid Snake, where he was originally depicted as an Asian-looking man with black hair. In Metal Gear Solid, Miller is depicted with blond hair and aviator sunglasses. Revisions of Metal Gear 2, from the 2004 mobile phone version and onward, depicted Miller in this design. Because of this, the MSX2 version of Metal Gear 2 is the only game he appears in where he doesn't wear his sunglasses. His original biography, given in the MSX2 manual and the Metal Gear Solid 4 Database, stated that he was a third generation Japanese American, and was born in the United States sixty years after his grandparents immigrated there from Japan. However, this account was later retconned in Metal Gear Solid: Peace Walker.

Metal Gear Solid
Master Miller is murdered prior to the events of Metal Gear Solid, with his role on Solid Snake's radio support team impersonated by Liquid Snake. His portrait in the game's Codec screen is that of Miller, complete with sunglasses, though Liquid's actual physical resemblance is used during some moments of fourth wall breaking; he physically "unmasks" himself to the player via the Codec screen, upon revealing his true identity, and later asks Snake whether he liked "his sunglasses." These actions, however, were kept within the novelization but omitted from Nastasha Romanenko's book In the Darkness of Shadow Moses: The Unofficial Truth.

Depending on which ventilation shaft the player entered through, Miller's introductory call to Snake will be slightly different. If the player entered the bottom ventilation shaft, Miller will talk to Snake about the species of rodents inside the shaft that Snake is following, the Alaskan field mice, and also explain that they have a tendency to eat any young that isn't their own, which Snake points out is a survival instinct to ensure their genes are passed on. This briefly foreshadows the revelation on how Snake was conceived.

Earlier in the game, during Snake's fight with Liquid's Hind D, if the player attempts to contact Miller by Codec, there will be no response. This serves as a bit of foreshadowing as to who "Miller" really is. Similarly, if the player tries to contact Miller by Codec during Snake's fight with the M1 Abrams Tank piloted by Vulcan Raven, there will be no response.

While Miller (Liquid in disguise) was trying to convey his suspicions about Naomi Hunter by pointing out various flaws in her backstory, he claimed that he used to work for the FBI. As Snake stated that he was unaware of this, and due to his Codec's monitor being turned off (preventing others from listening in), this may have been a lie crafted by Liquid.

Although Metal Gear Solid heavily implies that Liquid was involved in Miller's death, the identity of the person who physically killed him has never been revealed. Prior to the second end credits of Peace Walker, a timeline states that Miller was killed in his home by an "unknown assailant."

Miller appeared as a hallucination in both the Metal Gear Solid: Digital Graphic Novel and the novelization, although in a different manner in each of the two. In the former, Miller managed to somehow dispose of Psycho Mantis, and then get Snake to the REX hangar, only for the both of them to be "ambushed" by Liquid and Revolver Ocelot. Snake managed to deduce it was an illusion after seeing Ocelot retaining both arms (his right arm was amputated earlier by Gray Fox). In the latter, Miller also appeared, having presumably disposed of Mantis, although after exiting through a door, they somehow end up at Kiddieland, with Miller later disappearing.

Metal Gear Solid 4: Guns of the Patriots
Master Miller makes a vocal cameo in Metal Gear Solid 4: Guns of the Patriots, when, while crawling through a ventilation duct in the tank hangar in Act 4, an audio flashback of when Miller (actually Liquid Snake) contacted Solid Snake while crawling through the vents. His voice is also heard when Snake takes the elevator down to the underground base, with an audio flashback of Miller telling Snake that Naomi Hunter may be a spy. In addition, a "ghost" of Miller, based on his face portrait from Metal Gear Solid, will apparate in a photograph.

Metal Gear Solid: Peace Walker
Kazuhira Miller appears as the secondary protagonist of Metal Gear Solid: Peace Walker. His presence in the game was hinted at with a leak showing his younger self at Playa del Alba on September 20, with Hideo Kojima later confirming that he is indeed a younger version of Master Miller at TGS 2009.

According to Kojima, Miller's Peace Walker design was partly based on the flight captain from Westworld per his request, although the development team had never heard of the film.

Miller's view of the Militaires Sans Frontières as being a "new type of business" foreshadows the development of the war economy and the spread of PMC activity across the world, as portrayed in Metal Gear Solid 4. Also, his reference to the war economy likewise refers to the economy in the same game. The ending scene (where Miller is explaining that he felt they would be an important asset in the world economy when explaining his motives for being involved in Cipher's plan alongside Paz and Zadornov) was also first exposed to the public in the beginning and end of the Tactical Espionage Operations trailer.

"We're not mercenaries. We're not a foreign legion. MSF's a business. A new kind of business."

- Kazuhira Miller's soldier profile quote on the Mother Base staff menu.

Miller is a unique staff member at Mother Base, available from the start of the game. He requests Big Boss assign him to any of the unit divisions as they were initially understaffed. His skill ("Mother Base Deputy Commander") increases morale of all staff on assigned team. However, if he is assigned to the Combat Unit he cannot be used in missions. His job is also listed as MSF Subcommander.

If the player (either as Big Boss or another MSF member) calls Miller while wearing his uniform during a mission, he will tell the player that he gave them a dirty uniform, as he goes by a certain fashion routine. In addition, some of his calls will have him remarking that it "looks like viewing [himself] in a mirror." and requesting that the soldier not "cause any trouble by dressing up like [Kazuhira Miller]" to Big Boss and a MSF Male soldier, respectively, foreshadowing the fact that Liquid Snake will pose as Miller in order to trick Solid Snake into activating Metal Gear REX during the events of Metal Gear Solid.

If the player rescues a female POW via Fulton recovery, Miller will remark "oooh, all right!" and "nice" instead of his usual comments regarding a successful retrieval, which goes in line with him being a playboy.

An Extra Op featured in Peace Walker portrays Miller as being bisexual, with Big Boss having the opportunity to go on a date with him to the beach. The humorous tone of this mission (similar to the "Date with Paz"), along with Miller's womanizing characteristic throughout the story, suggests non-canonicity. S-ranking the mission will also result in players acquiring the Miller uniform as a usable uniform for Extra Ops and Main Ops, although the calls throughout the mission the uniform is worn in imply that Miller simply loaned it to the player (as either Big Boss or one of the MSF Soldiers) for use in the mission. There are several hints in the game that point towards Miller's bisexuality, at least in the case of Big Boss. If the player dress Snake with the swim trunks, Miller will be outraged at first, but finally will conclude that "they don't look bad on him." His briefing about the Naked Uniform in the Japanese version included a suggestion that he and Snake should do naked skydiving some day, and Paz comments in her diary that, despite his womanizing behavior, Miller only trusts Snake. In addition, the Heiwa to Wahei no Blues drama tracks includes among other things a drama track based on the Date with Kaz extra op, and in the Sauna drama track, Big Boss's outrage can be interpreted as him being jealous of Miller going for girls (although in context, it was referring to how Miller's womanizing is causing morale problems among MSF and Mother Base). Miller's infatuation with him was confirmed in Ground Zeroes.

The progress of the Date with Kaz mission is similar to the Date with Paz mission. Namely, the player can give pre-selected COOP Codec calls to Miller to either boost his affinity or lower it, placing a magazine in front of Miller will get him to react, completing the mission involves using the love box, failing the mission has him storming off, and using the Battle Cry will result in a Codec conversation between the other members of MSF. However, there are some differences: the Codec calls are completely optional, and Miller will simply react to Big Boss wearing a naked uniform of any kind, whereas Paz would run away if he wears a naked uniform of any kind. In addition, if the player decides to wear the swim trunks, Miller will wear a speedo. Also, if the player utilizes CQC on Miller, not only can the player managed to take the opportunity to get the Patriot design specs from Miller while he is unconscious, but it would also result in a tremendous boost in affinity from Miller, which often makes getting an S-rank much easier in comparison to the Date with Paz mission. Also, beating him up hard enough will also result in his sunglasses breaking. If the player manages to get Miller to fall asleep with "Time to say 'Good Night!!!'" and then lies on him, Miller will briefly mutter "Stop it... I'm not that kind of guy..." If the player managed to interrogate Miller, in the Japanese version, he will say what translates to "I'm not hiding anything!". In the English version, doing said action will have Miller say "No skeletons in my...closet," both a euphemism for hiding a dark secret, and double entendre for an expression indicating someone hasn't revealed they were either bisexual or homosexual.

When commencing the Main Op "Head to the Control Tower," the sounds of an engine can be heard in the background while Miller is giving the mission details, since he and the other MSF soldiers are preparing to aid Snake, via helicopter.

Other than his role in the main game, Miller also had a role in some radio dramas released with the CD Metal Gear Solid: Peace Walker - Heiwa to Wahei no Blues. The first five drama tracks, "Snake & Kaz (Encounter)," gave in full detail the circumstances behind Miller's meeting of Big Boss and later joining MSF, something that was previously only given in a briefing tape as a conversation between Big Boss and Miller. The dramas in question revealed the circumstances behind his joining as being a lot more dramatic than the briefing tape implied. Aside from this, the other drama tracks included "Snake & Kaz (Entry Gate)," "Snake & Kaz (Love Cardboard)," "Snake & Kaz (Sauna)" (which elaborated on the events of the fight between Big Boss and Miller in the shower room that Paz had earlier alluded to in one of her diary tapes), "Snake & Kaz (Strongest Armed Duo)," "Snake & Kaz (Mission Complete)," and "Kaz Radio. Outer Ops "Boss Radio."" Tomokazu Sugita reprises his role as Miller in these segments, as well as sang a character song for Miller called "Minato no Yoko, Yohohama, Yokosuka," which is Miller's own take on the Japanese song.

Miller is also the only major character other than Big Boss to get his on action figure under the Peace Walker line for Square Enix's toy-making subsidiary Play Arts Kai. Similar to Big Boss's Battle Dress action figure, Miller can also be customized into an MSF soldier wearing his uniform. Also similar to the Battle Dress action figure, Miller's figure does not come with a passcode that unlocks a volunteer soldier. Both Miller and Snake's respective action figures were also included in a limited edition set that included the Love Box that was released for Japanese events. Similarly, he's also the only major character besides Big Boss to have a cover for one of the releases for Peace Walker dedicated to him.

Miller and Vladimir Zadornov share the same motion capture actor: Takashi Kubo.

Miller later made a reappearance in the Konami-sponsored event E3 Battle, where he faced off against Rat Patrol Team 01. He ended up losing to the combined efforts of Rat Patrol Team 01, despite his extensive combat experience. His bio for the site erroneously lists Miller's first appearance in Metal Gear Solid rather than Metal Gear 2: Solid Snake.

"KAZUHIRA MILLER FIRST APPEARED IN Metal Gear Solid (1998) Big Boss' second-in-command in the Militaires Sans Frontières, later retained as support staff for FOXHOUND operations."

Metal Gear Solid V: Ground Zeroes
Miller was hinted in the PAX Prime 2012 trailer to be a returning character for Metal Gear Solid V: Ground Zeroes (then known simply as Metal Gear Solid: Ground Zeroes). At one point, he tells Big Boss shortly after he arrives at Camp Omega "Excellent, Snake. Age hasn't slowed you down one bit!", something that Roy Campbell will tell Solid Snake when infiltrating Shadow Moses in Metal Gear Solid, should the player board an elevator quickly.

In the TGS 2013 showing of Ground Zeroes, Miller appeared in two demos: one dealt with the nighttime portion of the game. Miller told Snake that the man he rescued was not Chico in the ending of the game, although he nonetheless brought the prisoner under the fold as a recruit before telling Snake that next time, he'd make absolute certain that he actually rescues Chico and Paz.

In the other demo, a special TGS demo covering a daytime Extra Ops mission, Miller had Snake be sent to Camp Omega to retrieve classified intel from one of their moles, Brian. After Snake escaped from the facility by hijacking a Jeep (due to the original escape plan going awry due to being spotted), Miller commented that he was impressed that Snake could "rep a car like that," though he admitted that he shouldn't expect less of his superior, and that they'd analyze the data on the cassette tape, estimating that the results of their findings would be ready "by the time we launch."

The Japanese version of Ground Zeroes features Miller on the cover alongside Big Boss, although he is absent in the overseas covers. According to Kojima, the reason for this was due to Peace Walker 's poor sales outsi de Japan, resulting in most people being unfamiliar with Miller. He further elaborated on his rationale in a series of Twitter posts on December 23, 2013, explaining that he let the overseas branch of Konami handle the key artwork for the overseas version, which he had been told that Miller, due to Peace Walker 's release on the P layStation Portable, was likely to be a little known character. When the final overseas cover was unveiled, he discovered, much to his surprise, that Miller had actually been well received, and that people were actually wondering why he was removed from the cover.

Although Miller did not appear in the extended trailer for the DLC mission Déjà Vu, the March 2014 issue of Game Informer confirmed that Miller would appear in the mission, and would quote various lines from the original Metal Gear Solid.

In the trailer for the DLC mission Jamais Vu, Miller briefed Big Boss on a request for the MSF to investigate the naval facility at Cuba due to Body-Snatchers taking over the facility after the crash of a Soviet commuter jet nearby. He then, alongside Big Boss, recruited Raiden, a cyborg from the future, to stop the threat, as his cybernetic body made him immune to the bioroids attempts to take over his body. Miller also commented that, in exchange for Raiden's services, he could retrieve the XOF patches from the base that Big Boss found.

In both Extra Ops, Miller mimics the voices of various characters. For the Déjà Vu mission, he mimics Roy Campbell, Psycho Mantis, Meryl Silverburgh, and Gray Fox. For the Jamais Vu mission, he mimics George, Kevin Washington, and Boris. Aside from the main aspects of both missions, he also mimicked and quoted Solid Snake, Otacon, The Boss, and Drebin for Metal Gear Solid, Metal Gear Solid 2, Metal Gear Solid 3, and Metal Gear Solid 4, in addition to quoting his own lines from Metal Gear 2 and Peace Walker. He also used one of Big Boss's quotes from Metal Gear and attributed it as his own. He'll also mimic Mantis after all of the main Metal Gear titles are removed. During the endgame quiz for the latter Extra Op, He will also mimic Liquid, Vulcan Raven, Ocelot, and Campbell.

In the Japanese version of Ground Zeroes, the five part radio drama detailing how Miller and Snake met was included among the Mother Base Archives section of the tapes menu. Because of the game possessing seven language subtitles to choose from, it also marks the first time that the drama was released with an English translation.

Despite the game taking place months after Peace Walker, and that Miller sounds relatively the same during his radio calls in Ground Zeroes, his voice sounds remarkably older once rescued at the end of Ground Zeroes, more aligned with his voice in The Phantom Pain (which takes place 9 years later). As Miller is voiced by the same actor in all three titles, it is unknown why this is the case.

Aside from the main game, Miller is also an officer character in the Mother Base development game on the Ground Zeroes app for the iPhone and Android devices, available from the start alongside Big Boss.

After the release of Ground Zeroes, many fans have noted Robin Atkin Downes's delivery of Miller's line "They played us like a damn fiddle!" upon his rescue at the end of the game which became a popular meme for the fanbase of Metal Gear Solid. When asked about it, Downes jokingly said, "You’re about to see some major music coming out of Kaz in the next game" and that "Fiddling is just the beginning of it."

Metal Gear Solid V: The Phantom Pain
Miller was confirmed as a character in Metal Gear Solid V: The Phantom Pain, as seen in the GDC trailer released on March 27, 2013. He is seen at the hospital with Big Boss and another patient. He is seen with lacerations across his face, bleeding, demanding that Big Boss not die. Just before the scene ends, Miller asks the doctors "What about him?" referring to the MSF medic in the ward. Miller was also heard talking about Diamond Dogs and their new home, although it was not made clear whether he founded the organization before or after Big Boss's coma, due to the GDC 2013 trailer incorporating scenes from both Ground Zeroes (the game that explained the circumstances behind Big Boss's coma) and The Phantom Pain (the game that occurred after Big Boss's coma). Kojima also mentioned him in the pre-E3 showing for The Phantom Pain, when citing the differences in delivery required for the Fox Engine regarding facial expressions and emotions.

In the E3 2013 trailer, Miller lost his right arm and his left leg, despite his Metal Gear Solid artwork showing him with a fully human right arm and left leg. In the extended director's cut of the trailer, Miller wears a trenchcoat, sunglasses and a Diamond Dogs beret, and oversees Ocelot's torture of Huey Emmerich and Quiet. Although the official Metal Gear Solid Facebook page gave the impression that the torture overseer might have been a new character, the official Konami Facebook page confirmed via the "with ___" feature that the man was indeed intended to be Miller. The E3 2014 trailer also officially confirmed that Miller was the man.

Similar to Big Boss, Miller's in-game appearance for both games will be a combination of several different people.

Miller losing his left leg is similar to Conrad Roth injuring his left leg in an attack by wolves early on in Tomb Raider (2013). Coincidentally, both characters were voiced by Robin Atkin Downes.

For Miller's Mother Base role, Miller has the career of Mother Base XO, which facilitates increased staff morale in unit. He also has an E in combat (owing to his conditions in the game), C in R&D, A++ in both Base Development and Support, and A+ in both Intel and Medical, and he is fluent in English, Japanese, and Spanish.

According to Hideo Kojima's notes in the Piggyback Collector's Edition Guide's art gallery, Miller's role was to give all players, even those who have no tendency for vengeance themselves, a motive for exacting it, as he noted that the level of desire for revenge would most likely be stronger among those players who have already played Peace Walker and Ground Zeroes. He also confirms that Miller and Ocelot are not friends/allies at all, and in fact, none of the Mother Base staff are buddies, only working alongside each other because of Snake, and would collapse the moment their leader ceases to exist.
