Colorado World War II Army Airfields were major United States Army Air Forces (USAAF) training centers for pilots and aircrews. During World War II these Colorado airfields were under the command of Third Air Force or the Army Air Forces Training Command (AAFTC) (A predecessor of the current-day United States Air Force Air Education and Training Command). However the other USAAF support commands (Air Technical Service Command (ATSC); Air Transport Command (ATC) or Troop Carrier Command) commanded a significant number of airfields in a support roles.
