The Air Force Combat Ammunition Center (AFCOMAC) is a United States Air Force training course developed to provide the Air Force munitions community with advanced training in mass combat ammunition planning and production techniques. It uses a combination of in-depth classroom instruction combined with a four-day intensive practical exercise (IRON FLAG) using live munitions in a realistic, bare-base scenario. AFCOMAC was established in 1985 at Sierra Army Depot, California, as a response to a perceived degradation in the USAF's ability to rapidly produce ammunition for air combat operations during combat. AFCOMAC's intensive training effort from 1986 through 1991 helped prepare USAF munitions personnel for their role in the first Gulf War. Later AFCOMAC moved to Beale AFB, California.
