Two Airmen with the 932nd Airlift Wing Security Forces Squadron, acting as enemy combatants, fire special paint rounds at approaching SFS patrols during a training exercise near the Sparta Shooting Complex, Sparta Ill., June 9, 2015. Special protective gear was worn by all participants in the exercise. The use of the paint rounds adds a heightened sense of realism to the training. (U.S. Air Force photo/Tech. Sgt. Christopher Parr)
