Kyle Schneider was the leader of the resistance movement at Galzburgh, South Africa. He was once an architect who was forced to be part of Outer Heaven's design staff, but joined the underground movement when his wife and child were killed (the exact circumstances of their deaths are never revealed).During Operation Intrude N313, he lent his knowledge of the fortress layout to Solid Snake, serving as a sort of navigator during the mission. However, Snake loses contact with Schneider just before he was about to reveal the identity of the Outer Heaven leader and he is presumed dead afterwards.
In reality, Schneider survived but was taken captive by clean-up crew deployed by NATO after a massive bombing campaign against Outer Heaven. He was used as a guinea pig for NASA's top-secret "Black Ninja" extraterrestrial environment special forces unit project. He was outfitted with an experimental flex armor suit and reflex-enhancing drugs (in what may have been a predecessor to the Cyborg Ninja project). When the Black Ninja unit was disbanded, Schneider and other members of the unit fled to Zanzibar Land and assisted Big Boss during the War of Mercenaries in 1997.
In spite of the fact that Schneider originally opposed the Outer Heaven regime, he was grateful of Big Boss due to the fact that he provided refuge to the surviving members of the resistance movement after the NATO air strike that left most of them dead. He served as a vital member of Zanzibar Land's elite Mercenary after the war, repaying Big Boss for the favor.
