Metal Gear (weapon)



Metal Gear is the codename for a series of powerful bipedal tanks, usually armed with nuclear weapons.

Definition
The general definition of a Metal Gear is a mobile nuclear launch platform similar in purpose to ballistic missile submarines. However, its precise definition is debatable, as many other weapons have been designed to fill a similar role, or have used the same technology. The individual units have varied greatly in appearance and size, but their purpose has always been the same—to destabilize the global balance of power via the threat of covert long-range nuclear attack.

The term "Metal Gear" was coined by Soviet weapons scientist Aleksandr Leonovitch Granin to describe to Naked Snake in 1964 the "missing link" between infantry and artillery: infantry could roam the battlefield at will, but were both vulnerable and lacking in firepower; artillery could inflict immense damage upon an opponent while resisting similar damage, but was at the mercy of the terrain. Granin envisioned a tank with legs, enabling it to quickly traverse the battlefield, dealing and repelling force on a scale never before seen.

Following an encounter with a Gekko in 2014, Otacon explained to Old Snake that what makes a "Metal Gear" is specifically its nuclear launch capability. Taking in Granin's original coinage of the term, it can be therefore assumed that a Metal Gear can be defined as a bipedal nuclear weapon. Not only does this negate the Gekkos and the Mk. II/Mk. III from being true Metal Gears, but it also discounts Metal Gear RAY.

History
The Metal Gear concept was first conceived by the Soviet Russian weapons researcher Aleksandr Leonovitch Granin as a way to connect infantry with artillery, making it invulnerable to firepower shortages and terrain. However, his concept was looked down upon and turned down by the Khrushchev regime, and the Volgin faction of GRU later turned him down after his attempt at making it for them failed to produce results sufficient enough for them to use effectively. He also supplied information about Metal Gear to his American colleague, Huey Emmerich, who then used his concept for his own. Shortly before his death, Granin planned to send Emmerich all his research to him. However, it was intercepted by the Philosophers' triple agent Ocelot, and instead sent to the CIA Director as a future weapon for America.

In 1970, the American government hired Nikolai Stepanovich Sokolov to help develop an ICBM based version of the Metal Gear concept, in addition to a prototype version. These weapons were later stolen by the FOX unit, under CIA orders, and brought to the San Hieronymo Peninsula. The prototype, Metal Gear RAXA, was later destroyed by Naked Snake and his resistance (although due to misinformation, they were initially led to believe that it was the actual model). The ICBM-based model, the ICBMG, was later used in an attempt to make a nuclear strike against America by Gene (acting against Pentagon orders to use it against Russia), but was ultimately destroyed by Naked Snake and his resistance movement. A CIA member who was a contact of the former CIA Director, Hot Coldman, also managed to procure the Metal Gear documents and send them to his employer during the confusion of the current CIA Director's death by Ocelot's hand, which was summarily covered up as a suicide.

Coldman, with the documents he received, then recruited Huey Emmerich to design the various AI weapons, as well as the frame and weapons system for Peace Walker, while leading him to believe that it would not be fired even once. It was then used in various tests in Central America, until Huey defected upon learning that Coldman planned to launch a live nuke from Peace Walker. The various AI weapons were later destroyed by Big Boss's Militaires Sans Frontieres, and Peace Walker eventually ended up sacrificing itself to stop the transmission of false data to NORAD. Later, Huey and Strangelove were commissioned by the MSF to help build their own Metal Gear, codenamed ZEKE. However, it was hijacked by a spy for Cipher, who was behind most of the Peace Walker Incident, and ended up heavily damaged. The United States in the meantime abandoned the idea of Metal Gear being a true revolutionary weapon for the time being.

Eventually during the 1990s, the mercenary nation of Outer Heaven developed the TX-55 Metal Gear with forced help from Robotics expert Dr. Drago Pettrovich Madnar. It was later destroyed by Solid Snake during Operation Intrude N313, although Madnar, despite earlier being against its creation, later praised it as his life's work. Afterwards, Madnar also attempted to create a Metal Gear for America, but the American government did not agree to it, and was later ostracized and shunned by the scientific community for it. Because of this, Madnar willingly cooperated with Zanzibar Land in creating the revised Metal Gear D and the intended mass production of both Metal Gear D and Metal Gear G. Metal Gear D was later used to raid various nuclear storage sites around the world, until it was destroyed by Solid Snake in Operation Intrude F014. In addition, in May of 1996, due to the suicide of Admiral Boorda, a new Metal Gear model proposed by ArmsTech was allowed into the Pentagon's Black Budget.

Meanwhile, Metal Gear REX ended up becoming a black project co-developed by DARPA and ArmsTech to combat a global trend in military downsizing. In 2005, during a field exercise of REX's capabilities, Metal Gear REX was hijacked by a terrorist group called the Sons of Big Boss on the Shadow Moses Island nuclear disposal facility. It was later destroyed by Solid Snake, although not before the latter had unwittingly activated it due to misinformation.

Despite its destruction, various derivatives were created due to Revolver Ocelot leaking the REX data to unstable regions of the world, leading to the creation of the anti-Metal Gear NGO Philanthropy. In addition, due to this as well as partially the revelation of the Army's involvement in REX, Metal Gear RAY also developed by the Marines as an anti-Metal Gear, and a cyber-warfare based Metal Gear named Arsenal Gear was developed by the Navy, leading to a rivalry between the two that was later exploited by the Patriots to create an incident to steal Metal Gear RAY for Arsenal Gear for their S3 Plan, as well as framing Philanthropy.

As the war economy defined the world by 2014, ArmsTech (renamed as AT Corp) mass-produced a miniature Metal Gear codenamed Irving by the US military, otherwise known as Gekko while Philanthropy developed Metal Gear Mk. II. Both Metal Gears are not mobile nuclear launch platforms: the Mk. II is a remote mobile terminal designed for stealth scouting and communication, whereas the Gekko was essentially the equivalent of a jeep or tank. Although Gekko did not meet the requirement of being a nuclear launch platform, it did fulfil Granin's original definition of the concept - a walking tank that could traverse any terrain and withstand heavy firepower. However the original Metal Gears did still exist and were used during this time.

Intercontinental Ballistic Metal Gear
See main article

The Intercontinental Ballistic Metal Gear (ICBMG) was developed for the CIA by Nikolai Stepanovich Sokolov in 1970. Sokolov was heavily influenced by Granin's designs when creating this Metal Gear. The idea for this version of Metal Gear was to use a large rocket to launch the actual Metal Gear unit itself into near-orbit before releasing it, allowing it to parachute back down to the target location where it would then launch its payload of nuclear weapons.

Metal Gear RAXA
See main article

Metal Gear RAXA, pronounced "rasha" (/ræʃæ/), was a prototype of the ICBMG created in 1970. Although considered to be the first Metal Gear, neither RAXA nor the ICBMG truly lived up to Granin's original vision of a bipedal walking tank.

Metal Gear ZEKE
See main article

Metal Gear ZEKE was the first fully bipedal tank. It was designed by the Militaires Sans Frontieres at the Mother Base by Huey Emmerich and Strangelove in 1974. It is equipped with a railgun, a radome, and a jetpack to increase mobility. Originally an unmanned weapon, Paz Ortega Andrade hijacked and modified it as manned weapon, and planned to launch a nuke at the United States's Eastern Coast if Big Boss (Naked Snake) didn't rejoin Cipher; however, it was heavily damaged in the ensuing fight. Strangelove noted afterward that it could at least regain the ability to walk, as she had made a backup copy of the AI, but whether it would be used again was up to Big Boss.

TX-55 Metal Gear
See main article

TX-55 Metal Gear was the first documented bipedal tank designed at Outer Heaven by the Eastern scientist Drago Pettrovich Madnar in 1995. TX-55 proved Granin's vision to be a potent weapon — a mobile nuclear launch system that made stationary missile silos obsolete. This Metal Gear was never actually deployed, as it was destroyed before its development could be completed.

Metal Gear D
See main article

Metal Gear D was a re-designed version of TX-55 (the TX-55 was a prototype for Metal Gear D ) and was very similar in appearance. It was also developed by Dr. Madnar within Zanzibar Land in 1999. This Metal Gear also featured additional weapons for close range combat.

Metal Gear G
See main article

Metal Gear G, or Gustav, was to be a small-scale, mass produced version of D, (without nuclear capability) designed to assist infantry in local combat areas. It was in development around 1999, but was never produced due to Zanzibar Land's collapse shortly thereafter.

Metal Gear REX
See main article

Metal Gear REX is a Metal Gear developed for the United States Army. It was developed by Dr. Hal Emmerich, in a joint venture between ArmsTech and DARPA, at the nuclear weapons disposal facility on Shadow Moses Island in 2005. It was considered to be a revolutionary weapon - unlike all previous iterations of Metal Gear, not only could REX deliver a nuclear weapon both to and from any point on the globe, it was undetectable and untraceable. All previous Metal Gears were merely mobile ground-based launch systems for nuclear missiles, little more than the land-based equivalent of ballistic missile submarines. REX utilized a railgun, which fired much smaller projectiles without chemical propellants - factors which made them virtually invisible to radar. It thus completely negated the theory of Mutually Assured Destruction - whoever controlled it could launch a nuclear attack at any target at any time without fear of reprisal. Additionally, unlike all the previous Metal Gears, REX's legs were heavily armoured rendering grenades useless.

Metal Gear RAY
See main article

Metal Gear RAY is a Metal Gear originally developed for the United States Marine Corps. But it's only a Metal Gear by Granin's initial definition - although RAY is a bipedal weapon, it lacks any form of nuclear armament. However, it was originally created under the premise of nuclear strategy. In addition, it did serve as part of a true Metal Gear's "conventional" armament - Arsenal Gear. RAY was designed and developed by the Pentagon and the Marines in 2007 as a countermeasure to the abundance of Metal Gear REX derivatives being developed due to REX's plans being leaked onto the black market after 2005. For this reason, it was, until the creation of the Gekko, the only Metal Gear designed for close-range battle.

RAY is notable for being the first attempt at Metal Gear mass-production. The Patriots (via the U.S. Navy) produced twenty-five mass-produced Metal Gear RAY units to serve as guards for Arsenal Gear in 2009. They differed from the original RAY in that they were unmanned (the original intention of the Marine Corps), had no tail and were slightly smaller.

Arsenal Gear
See main article

Arsenal Gear was a Metal Gear developed for the United States Navy. It's an evolutionary step ahead of all previous Metal Gears, functioning as a submersible warship, instead of a bipedal tank. While capable of the same covert long-range nuclear attacks that define Metal Gears, this was merely a layer of its numerous defenses. Its true threat lay in its ability to conduct information warfare through the use of its onboard artificial intelligence (GW) in 2009.

Gekko
See main article

Gekko were the second attempt at mass producing Metal Gear models, and the most successful. Given the codename IRVING by the U.S. military, this model was designed for short-range combat, and Gekkos were rapidly replacing tanks by 2014. They were equipped with assault weaponry, a near sentient A.I. system and near impregnable armour on the body. Their powerful legs were inspired by both REX and RAY, built with artificial, self-repairing muscle tissue, making it more agile than previous Metal Gear variants and it's overall appearence resembles a smaller ZEKE.

Although not technically Metal Gears due to their lack of nuclear launching capability, the Gekko more than fulfil Granin's vision of bipedalism, indeed overcoming the limitations faced by both infantry and artillery.

Metal Gear Mk. II and Mk. III
See main article

The Metal Gear Mk. II (later superseded by the Metal Gear Mk. III) was a robotic companion with a blue exterior. The Mk. II served as a recon device but could also shock enemies (knocking them unconscious) and was equipped with Stealth camouflage in 2014. The Mk. III replaced the Mk. II, following the Mk. II's destruction. The Mk. III served the exact same purpose and functioned the exact same way, the only difference being its red exterior.

Although it was not actually a Metal Gear, the Mk. II was named as such by Otacon so that he "would never forget that [he] was the one who built [Metal Gear REX]."

Outer Haven
See main article

Outer Haven is a modified Arsenal Gear model that Liquid Ocelot stole from the Patriots in 2014, and hid at Shadow Moses Island. Outer Haven houses a repaired GW, which was recovered from Arsenal Gear. Haven is armed with missile launchers and later equipped it with Metal Gear REX's railgun. As well as utilizing OctoCamo, Haven has a large supply of Gekko units and Haven Troopers, who patrol its insides. Also, just like Arsenal Gear, Outer Haven has its own force of mass-produced Metal Gear RAY units, which were used to attack the USS Missouri in 2014. Outer Haven also has &quot;Mount Snakemore&quot;, with the faces of the four Snakes (Big Boss, Liquid Snake, Old Snake, and Solidus Snake) in Mount Rushmore-like style. However, this was probably apart of one of its OctoCamo disguises, so therefore was likely not a permanent feature.

Names
At least one Metal Gear took its name from U.S. designation codes of IJA fighters during WW2, e.g. Gekko took its name from the Nakajima J1N1-S, while others are named after animal species, e.g. Metal Gear RAY from manta ray. However, the Patriot AI's conversation with Raiden, towards the conclusion of the Manhattan Incident, revealed that REX and RAY's codenames could also be derived from the Allied codenames for WWII Japanese fighter jets. More specifically, REX was was the name given to the Kawanishi N1K Kyōfū, while RAY was a name given to the Mitsubishi A6M2 Zero, similar to ZEKE.

Behind the scenes
According to Hideo Kojima, the idea of the "Metal Gear" weapon, a nuclear-capable walking tank, was conceived in response to the nuclear war hysteria during the mid-1980s that resulted from the Cold War, as the U.S. military had no mobile land-based nuclear weapons delivery system at the time.

Metal Gear Solid: Peace Walker allows the player to design a Metal Gear unit based on AI memory boards and parts retrieved from the AI Weapons, resulting in Metal Gear ZEKE.

Metal Gear-like enemies
Several bipedal weapons with two gun turrets are seen as enemies in Snake's Revenge, where they fire weapons upon detecting Snake. They are prevalent in the penultimate stage of the game, the main enemy base.

Metal Gear 2
See main article

Metal Gear 2 is from the non-canon game Snake's Revenge.

Metal Gear GANDER
See main article

Metal Gear GANDER is from the non-canon game Metal Gear: Ghost Babel. GANDER is armed with machine guns, missiles, rail guns, a flame thrower, and nuclear missiles.

Metal Gear KODOQUE
See main article

Metal Gear KODOQUE, codenamed Pythagoras, is from the non-canon games Metal Gear Acid and Metal Gear Acid 2. Armed with remote control missile launchers, beam cannon, and a plasma gun on its head. When inactive it is inside a cylinder shaped object fitted at it arms. Flat looking missiles can be found here.

Metal Gear Chaioth Ha Qadesh
See main article

Metal Gear Chaioth Ha Qadesh is from the non-canon game Metal Gear Acid 2. It is armed with a nuclear missile, neutron bombs, Vulcan Cannons on each of its arms, and a slot on the top for launching energy that can cause any equipped cards to be destroyed.

Eldera Metal Gear
An unnamed Metal Gear was developed in Eldera from the non-canon Snake Tales story "Confidential Legacy." Although it was initially believed to have been one of the Metal Gear REX derivatives resulting from Ocelot's leak of REX's data, it in actuality predated REX, having been made during the Cold War (more specifically, the 1960s) by America under a pro-American dictatorship in Eldera in a top-secret mission that Roy's brother Matt Campbell was involved in. It was onboard a Marine-controlled tanker, although it was confiscated by the Gurlukovich Mercenaries, and Meryl also ended up involved in it due to Gurlukovich claiming that Matt was killed by the Marines (in actuality, Matt was murdered by Gurlukovich himself after Matt ended up AWOL). Although it was initially believed that the Gurlukovich Mercenaries intended to give it to the Elderan guerillas, Gurlukovich, before meeting his doom at the hands of Meryl, revealed that he actually intended to salvage the nuclear-equipped ballistic missiles and the launch system for Metal Gear as a valuable commodity during the post-Cold War age. The Metal Gear was later revealed to have been significantly obsolete and a failure barely worth more than scrap metal, with nukes that were nothing more than cheap imitations.

Mesal Gear
Mesal Gear can be seen in the Mesal Gear Solid minigame featured in Ape Escape 3. It resembles the looks of the Shagohod. Although not able to be fought in battle, Mesal Gear is said to be armed with a "Lazy Cannon."

In Metal Gear Solid 3 's Snake vs. Monkey game, Mesal Gear makes an appearance as the Shagohod's "lazy cousin." It's a large, steel monkey version of Metal Gear with drills instead of hands as a joke to Volgin and the Shagohod. Atop the head is an evil looking ape with an eyepatch, which is a reference to Big Boss. Also, when knocked off the Mesal Gear's head, it engages Snake in combat with a punch-punch-kick CQC combo instead of the usual slap. Also, in the beginning of the level, Ape Fear, he says "Mesal... Gear..." during the overhead pan of the base and Mesal Gear, to which the monkey in question then shouts "Snaaake!" It later makes a reappearance in the Subsistence-exclusive level "Dawn of the Living Apes", where it is instead crouching, almost invoking the appearance of the Shagohod. Also, if Snake is detected by an ape, the alarm light on top of the Mesal Gear's head will start blaring with red colors and sounding an alarm siren.
