Kazuhira Miller

Kazuhira Miller, also known as Kaz, McDonell Benedict Miller, and Master Miller, was the second-in-command of the Militaires Sans Frontieres during the mid-1970s and FOXHOUND's survival trainer during the 1990s. 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 "Kaz" Miller was born in Japan, during the country's occupation by U.S. military forces, and was named after the Japanese word for "Peace" 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 light blue eyes and ash blond hair. 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-bother, 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 enrol 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 occuring 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 the disease, which she had 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 Kaz, 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 suicide at the JSDF Headquarters. He returned to America, only to learn his father had himself 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.

Miller's travels eventually led him to meet Big Boss (Naked Snake) in Colombia, where he was fighting for the rebels and Big Boss for the Colombian government. Big Boss and his men had already wiped out all of Miller's unit, so Miller prepared to take his own life with a grenade and die fighting. Big Boss was impressed with his spirit, likening it to that of a samurai, and convinced him to instead join the Militaires Sans Frontieres, with him later recovering at an infirmary. Miller played a vital role in the management of the MSF and supported Big Boss during his missions in Colombia.

In 1974, Miller brought Paz Ortega Andrade and Ramón Gálvez Mena to the Militaires Sans Frontieres camp on the Barranquilla Coast, after making sure that they weren't being followed by "their &quot;friends&quot; from Langley." Gálvez wanted to hire Big Boss and the MSF to repel an invasion force 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 production facility in the Caribbean to use as a base of operations (as their current base was in disrepair), although he began to suggest against accepting the offer after it became apparent that Gálvez was actually a KGB agent. Big Boss eventually agreed to take Galvez's offer for Paz.

From the offshore facility, dubbed "Mother Base," Miller provided radio support, via unidirectional signals, to the MSF forces as they entered Costa Rica. Big Boss managed to find a radio within a nearby shipping facility and contacted Miller, 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. 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. Miller later had FSLN comandante Amanda Valenciano Libre, her brother Chico, and Cécile Cosima Caminades extracted from Costa Rica, after Big Boss made contact with them. He 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 initially also attempted to stop Amanda from leaving Mother Base's sickbay, citing concern for her wanting to return to the battlefield while the latter is in crutches, only for Big Boss to point out that she wants to be in it for her comrades when Miller reported what happened, and suggested letting her out of sickbay for the time being as it was also beneficial to MSF's development. Metal Gear Solid: Peace Walker, Kojima Productions (2010). Kazuhira Miller: Snake, you there? // Naked Snake/Big Boss: Yeah. What’s up? // Kazuhira Miller: You’ve gotta talk to Amanda. // Naked Snake/Big Boss: What happened? // Kazuhira Miller: She wants to leave sickbay and get back onto the battlefield, but she’s not fully healed. She’s still in crutches – who’d be crazy enough to fight like that?! You have to talk some sense into her. // Naked Snake/Big Boss: Is she with you right now? // Kazuhira Miller: No, she’s in sickbay. She keeps shouting about how she doesn’t want to be there. She won’t shut up about it. She’s driving me- // Naked Snake/Big Boss: Let her go. // Kazuhira Miller: What? // Naked Snake/Big Boss: If that’s what she wants, let her go. // Kazuhira Miller: I’m really not in the mood for jokes, Snake. Naked Snake/Big Boss: I’m serious. Let her go. // Kazuhira Miller: Why? So she can come back in a body bag? // Naked Snake/Big Boss: I’m really not in the mood for jokes, Kaz. // Kazuhira Miller: What are you talking about? // Naked Snake/Big Boss: Amanda isn’t the type to just sit around in sickbay. She has a sense of duty – her purpose in life is to fight. The battlefield isn’t just the best thing for her, it’s the best thing for her compas, too. She’ll be a huge morale boost – that can only benefit MSF. // Kazuhira Miller: You think so? // Naked Snake/Big Boss: You’re good at fighting, Kaz – one of the best… but you’ve got a lot to learn when it comes to people. // Kazuhira Miller: … So where should I put her? // Naked Snake/Big Boss: I’ll think it over and find a team for her. Don’t worry, she won’t let us down. // Kazuhira Miller: Whatever you say, Boss. In addition, after former AI weapon researcher Dr. Huey Emmerich defected to the MSF and was assigned to the R&D Team to develop ZEKE, Kazuhira Miller also discussed the possibility of a weapon's name, and came up with Dr. Emmerich the name "Metal Gear ZEKE," as well as alluded to it needing a deterrent to truly stand a chance at becoming independent. 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 explains to a concerned Amanda that there was one thing Big Boss would never allow the Peace Sentinels 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). 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 Sentinels, arrested Gálvez (who was really Vladimir Zadornov, a KGB agent), and a dying 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 (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 (who were on their way to the Peace Walker unit to find out the answers to why The Boss and Big Boss fought in Tselinoyarsk) about what happened, with Coldman dying before he could give the abort code (a factor he had taken into account), forcing Big Boss and Strangelove to destroy the Peace Walker unit.

After the fiasco ended, Miller teamed up with Huey Emmerich and Strangelove in building Metal Gear ZEKE, which was created from the prototype weapons of the Peace Walker Project. In addition, Big Boss also tasked Miller with keeping an eye on Paz Ortega Andrade. Miller also considered having Zadornov recruited into the Militaires Sans Frontieres in order to boost the other Russian members' morale, but Zadornov's escape attempts forced him to change his mind against it. He also gave Big Boss a package delivered by EVA, which he also had it checked in case it carried explosives. Upon learning about Big Boss's former ties to EVA, he speculated that she and Big Boss were lovers, and mentioned that he not get "distracted" with her at the expense of MSF. In addition, 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 so they'd have a chance at gaining a deterrent, also asking Big Boss for permission, which he accepted after some thought, with Miller also citing that both the KGB and the CIA were busy attempting to cover the events of the Peace Walker project as another reason to install ZEKE with the warhead as a deterrent.

After Zadornov escaped captivity for the seventh and last time, Big Boss warned Kaz 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 disabling ZEKE and defeating Pacifica, Miller apologized to Big Boss because the former knew what Paz and Galvez 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, Miller presumably stopped working for Cipher altogether after the latter had 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 jeapordize any chances for MSF expanding.

Later career
At some point, Miller parted ways with Big Boss, adopted the name "McDonell Benedict Miller," and would later serve as a survival master within the SAS, the Green Berets, a U.S. Marine boot camp, and FOXHOUND. He also went on to volunteer as a coach in a mercenary school twice a year before eventually retiring. 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 there that he met and helped train Solid Snake, among which he trained Solid Snake on how to sense an enemy if sight alone couldn't help, various methods of deciphering transceiver frequency codes, how to endure torture, using CQB, as well as using common appliances to hide under. Miller also became married to a woman named Nadine, with whom he fathered a daughter, named Catherine. He would later divorce his wife, after which he decided to reside in Los Angeles with his daughter.

In 1999, Master Miller was reunited with and assisted Solid Snake, whom he provided with information on improving one's health, along with guidance on how to overcome the various obstacles he faced there. During Snake's battle with Big Boss, Miller referred to his former MSF commander and friend as a "monster."

By 2005, McDonell Miller had retired and 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, three days prior to FOXHOUND's revolt on Shadow Moses Island, Miller was murdered in his home by an unknown assailant. 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 Snake's commander Roy Campbell, who had requested Miller's support in the first place. The truth was later revealed when mission staff members Nastasha Romanenko and 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. Metal Gear Solid 2: Sons of Liberty, Konami Computer Entertainment Japan (2001). In the Darkness of Shadow Moses: The Unofficial Truth by Nastasha Romanenko ''"What’s the deal?" I said to Richard. "Is Miller right about Naomi?"'' ''"I don’t know, to be honest. It’s obvious there were things in Dr. Hunter’s past that I didn’t know about. I’m having them go over her background again." Richard was visibly upset, a rare occurrence. I suddenly wondered there had been something between him and Naomi. Richard lit a cigarette and continued in a more composed tone.'' "But if what Miller said about Naomi is true, it raises questions about him in turn." "Why do you say that?" "He’s supposed to be in his cabin in Alaska." "So I hear." ''"How did he manage to find out so much about Naomi by himself and from the middle of nowhere when the DIA investigators couldn’t?" Richard called one of his men over and ordered them to look into Miller’s activities. ''"You check up on even one of your own?" I asked as the agent who hurried away.'' ''"How do you know he’s one of our own?" Richard shot back, blowing a stream of smoke.'' "Should I assume you don’t trust me either?" ''"You’re the one who doesn’t trust me. Never have." He said quietly, and ground his cigarette into the ashtray. [...] "She was using me." He corrected and gave a hollow laugh. At that point, one of his men came tearing over. After an urgent whisper, Richard’s face grew grim.'' "What happened?" "Master Miller wasn’t Master Miller.” Richard was visibly shaken. "What?" ''"The man I sent to investigate Miller just reported in. He found Miller murdered in his home, up in Alaska.”'' ''"Who was it that we were talking to then --!" But there was no one who could provide an answer to that question.'' 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 characteristics
Kazuhira Miller was rarely ever seen without his aviator sunglasses, which he wore even in times where sunglasses would not have been appropriate, such as while indoors or driving during stormy weather. 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.

Aside from knowing Japanese and English, he was also gifted in knowing 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 analyses, 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 Galvez/Zadornov. He also enjoyed listening to train sounds, although this led to a disagreement with Cecile Cosima Caminandes, 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.

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.

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 the exact same time, causing them to report it to Big Boss. Big Boss then read Miller the riot act (presumably as the latter's punishment for his womanizing behavior), leading Miller to argue with Big Boss that caused them to get into a brawl in the showers, which Paz ended up witnessing. Similarly, he attempted to get into a relationship with Cecile due to her status as a blond parisenne, 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 Cecile, 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 Ortega Andrade, however, even though he secretly knew she wasn't who she claimed herself to be, implying that he does have some restraint in regards to his womanizing behavior.

Kazuhira 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 also knew about Solid Snake's status as a clone of Big Boss, and seemed to be aware of Cipher's plans of using him as an insurance policy, although he never told him. In his later life, he seemed to be 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 did view Big Boss as a friend, he did nevertheless side against him in Zanzibar Land.

Trivia

 * During his attendance one of the MSF's monthly birthday parties, Miller attempted to shield Paz from the crude atmosphere of the party, but he inevitably became drunk himself, and as a result he began mooning everybody, saying that they should see "the real Kazuhira Miller."
 * During his childhood, Miller had neighbors who owned a pet pig named "Pooyan." Due to the Fulton recovery balloons' resemblance to pigs, he was inspired to use the term "Pooyan mission" for operations that involved preventing enemy usage of Fulton recovery.
 * In 1974, Miller asked Cipher (Zero) about "the sons" of Big Boss. In his later years, Miller became a mentor to one of the sons, Solid Snake, while the other, Liquid Snake, was involved in his death in 2005.

Unconfirmed history
McDonell Miller, prior to joining the MSF and FOXHOUND, 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, decapitating the head interrogator in the process. While serving in FOXHOUND, one of the various radio codes that Miller taught Snake was changing the frequency by claiming to change cigarette brands, and also taught Snake how to determine whether a person was lying by their eyes.

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 in the re-released versions depicted Miller in this design. In the English re-release version of Metal Gear 2, Miller's first name was mistakenly spelled as "McDonnell." His original biography, given in the MSX2 manual (and included in 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, though 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 character 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.

Depending on which ventilation shaft the player entered through, Master 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, stating that it is a survival instinct to ensure their genes are passed on, which briefly foreshadows the revelation on how Snake was conceived.

Earlier in the game, during Solid 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 Solid Snake's fight with the M1 Abrams Tank piloted by Vulcan Raven or during the Genome Soldiers storming the prison area, there will be no response.

While Master Miller (Liquid Snake 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 Solid Snake stated that he was unaware of this, this may have been a lie crafted by Liquid Snake.

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 confirmed. Prior to the second end credits of Peace Walker, a timeline states that Miller was killed in his home by an "unknown assailant." It is not confirmed but Liquid most likely ordered a Genome Soldier to personally kill Master Miller.

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 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
Some fans have speculated that Miller's line of dialogue during Peace Walker 's opening ("Finally, we can leave all that crap in San Hieronymo behind...") is a reference of Hideo Kojima's views on Metal Gear Solid: Portable Ops.

According to Hideo Kojima, Kazuhira Miller's design was partly based on the captain from West World per his request, although the development team never heard of the character.

Miller's view of the Militaires Sans Fontieres 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 economly likewise refers to the economy in the same game. The ending scene (where Kazuhira 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 character 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 Kazuhira Miller simply loaned it to the player (as either Big Boss or one of the MSF Soldiers) for use in the mission.

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 Kaz 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 Kaz 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, Kaz 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.

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.

Kazuhira Miller is also the only major character other than Big Boss to get his own action figure under the Metal Gear Solid: 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.

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