PMC helicopter

A certain type of cargo helicopter was used by Liquid Ocelot's PMC forces during the Guns of the Patriots Incident in 2014, and again by Doktor in 2018.

Background
The helicopter was a large bulk helicopter, apparently used for carrying cargo and troops across battlefields. It appeared to take design elements from both the CH-53E Super Stallion and MH-47G Chinook.

By 2018 the variant used by Doktor was outfitted with an EMP device for missile deflection, used against pursuing MQ-320 drones.

History
The helicopter was chiefly used by Private Military Companies aligned with Liquid Ocelot in 2014. One such helicopter was used by Liquid Ocelot to leave the Middle East after a test of his new weapon against the Patriots.

Another was deployed to extract Vamp, Naomi Hunter, and Pieuvre Armement forces during Solid Snake's infiltration of South America.

The helicopter was also seen four years later in the hands of Doktor to extract Raiden, as well as many harvested brains of children from Denver in 2018, following his raid of World Marshal Inc. Headquarters during the World Marshal Incidents.

Behind the scenes
The fictional helicopter variant first appeared in Metal Gear Solid 4: Guns of the Patriots as a cargo helicopter used by enemy PMCs during the game. It is only seen in cutscenes, and cannot be interacted with by the player. It would later appear being flown by Doktor in ''Metal Gear Rising: Revengeance. ''Once again, its appearance is limited to cutscenes. Its appearance in Metal Gear Rising also showed more details of its interior and cockpit areas during the relevant cutscenes. Its designation was never identified in either game.

Several helicopters of this type are seen in promotional artwork for Metal Gear Solid: Snake Eater 3D, presumably standing in for Mi-24 Hind helicopters that actually appear in-game. Its appearance would nonetheless be an anachronism for the game's timeframe, which is set in 1964.
