McKinney

Private McKinney (named American soldier in-game) is a U.S. Army infantryman in the Anchorage Reclamation simulation and is first encountered in the year 2277 inside the simulation.

Background
He was a United States Army Infantryman and part of the initial assault on the abandoned mining town on the way to the Chinese listening Post. As the Lone Wanderer draws near, they can see McKinney lean out from behind a train car, ignoring the warning of a nearby soldier. He is killed a moment later when his head explodes after being shot by an enemy sniper.

Appearances
McKinney only appears in the Fallout 3 add-on Operation: Anchorage. McKinney is also mentioned in Fallout 4, his Anchorage veteran's flag being a contribution to the "treasures" of Jamaica Plain.
