Machinegun Kid was a former member of the SAS, the special forces unit of the British Army. While serving as an SAS commando, he trained to wield machineguns to the point of mastery, earning him his nickname. Eventually, he left to become a mercenary for hire and was later contracted by the private military company of Outer Heaven.

During Operation Intrude N313, Machinegun Kid encountered Solid Snake in Outer Heaven, while guarding the corridors of Building 1, and was determined to not let Snake pass through. Despite his impressive skills with his machine gun, Snake was able to use the room's large walls and fixtures as cover from his fire, and ultimately killed him.
Behind the scenes
The boss fight between Solid Snake and Machinegun Kid is briefly shown during Liquid Ocelot's exposition of the war between Outer Heaven and the Patriots, in Act 5 of Metal Gear Solid 4: Guns of the Patriots, shortly before the final battle with Liquid.
