Armitage is (apparently) the main patron of the crew in Neuromancer. Formerly a Green Beret named Colonel Willis Corto, who took part in a secret operation named Screaming Fist. He was heavily injured both physically and psychologically, and the "Armitage" personality was constructed as part of experimental "computer-mediated psychotherapy" by Wintermute, one of the artificial intelligences seen in the story (the other one being the eponymous Neuromancer) which is actually controlling the mission. As the novel progresses, Armitage's personality slowly disintegrates. He soon believes that Case is his subordinate during Screaming Fist, and attempts to escape imagined Russian forces using the escape pod on the Marcus Garvey. He is killed when he ejects into space with the airlock still open.
