Fan Casting Armitage in Neuromancer

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 which is actually controlling the mission.
