Haven Trooper suits

Haven Troopers were equipped with unnamed exoskeletons that they utilized in combat that gave them a superhuman prowess, making them feared soldiers on the battlefield.

History
Certain athletic female soldiers of Liquid Ocelot's private military were suited with exoskeletons that enhanced their physical capabilities beyond that the normal human, allowing them to cling to walls and leap several feet into the air. The vaguely green coloring of the exoskeleton, along with its distinctive abilities, is the reason the Haven Troopers were nicknamed "FROGS" by other soldiers.

The exoskeletons themselves appeared as tight grey jumpsuits with several pieces of leather-like strips adorning its shoulders and frontal torso. Multiple beige harnesses, straps, and holsters were also wrapped around each Haven Trooper. Their gloves had an unexplained physical mechanism hidden within it that tightly stuck to flat surfaces on command, as did their boots, which had small claws on the boot's toes. It is unknown if the Haven Troopers' primary characteristic; their abilities to catapalt themselves multiple feet into the hair without any momentum, originated from the exoskeletons, their nanomachines, or a combination of the two. All of this gear is peaked with an intimidating, vaguely skull-like helmet with red glowing eyes.

Behind the scenes
So far, the Haven Troopers and their exoskeletons have only appeared in Metal Gear Solid 4: Guns of the Patriots. Female players can also equip these exoskeletons in Metal Gear Online.

The Haven Trooper exoskeleton looks almost identical to Laughing Octopus's jumpsuit in her Beast mode, the only major difference being its boots, coloring, and headgear.
