must be physically transported to a point within range of the target(s) first. This is accomplished by having the ICBMG itself attached to the top of a rocket, launching it, detaching the unit at 3000 ft above the intended landing point, having it parachute back down to the ground, and launching its nuclear payload afterwards. In the game, Naked Snake encounters two models: the first is non-nuclear equipped test model Metal Gear RAXA which is used as rogue FOX leader Gene's decoy and the actual model that gets attached to a reproduced Saturn V rocket in the game's ending which Snake destroys in the cut-scene with the help of a defecting group of Red Army soldiers. Gekko is the new mecha featured in Metal Gear Solid 4: Guns of the Patriots. The Gekko is a mass-produced unmanned bipedal unit manufactured by ArmsTech Corp, and designated "Irving" by the U.S. Military; this stems from the American codename for the Nakajima J1N "Gekko" twin engine night fighter aircraft from WWII. Their frequent use by PMCs has caused it to be a replacement for tanks as a means of conducting armored warfare in urban areas. The Gekko have widespread use within the PMC community. Although not a literal Metal Gear, the top half of this mecha is reminiscent of Metal Gear REX's design with Metal Gear RAY's organic legs. It is unmanned and uses two large cameras as its "eyes", one mounted on its head, the other at the front of its hip assembly. These are backed up by other sensors, mostly passive. New features include a small robotic tentacle used to pick up small objects or grab targets. The Gekko is incredibly agile and maneuverable, thanks to a pair of flexible limbs that can act as either legs or arms. The legs are made from artificial muscle tissue cloned from embryonic stem cells of ungulate embryos. With these legs, the Gekko can pick up a man and throw him hard enough to penetrate a brick wall, deliver a kick that can overturn a 6x6 truck, dodge an RPG and kill its shooter, climb walls, crouch to enter buildings, run at speeds equivalent to a motor vehicle, and leap huge distances through the air. This model comes in multiple variants. Two of these variants are designed for standard combat; both carrying anti-personnel machine guns mounted inside the "nose", while one carries heavier machine
