ACE would rather fly than do anything else. During high school he worked after school and weekends to pay for flying lessons. He spent one year flying pipelines in Alaska and two years stunt flying for movies. He enlisted USAF at age 22. Duty most previous to G.I. Joe assignment: senior instructor USAF Fighter Weapons Squadron "The Aggressors" (pilot combat training school). He is a Qualified Expert in the following aircraft: F-5E, F-15, F-16, XP-14/F. Ace has one major character flaw: cutthroat poker. A predilection for gambling would ordinarily disqualify an applicant for the G.I. Joe team, but in Armbruster's case you can hardly call it gambling. He NEVER LOSES (Or, at least, no one that has ever beat him has lived to tell the tale). That's why they call him Ace!
