Defenders from the 96th Security Forces Squadron perform room-to-room sweeps during an active assailant exercise Nov. 17 at Eglin Air Force Base, Fla. The exercise took place on two fronts with vehicle accident at a fuel containment area and then inside a supply building. The goal of the exercise was to examine the base’s security and emergency response when tasked with overlapping yet separate scenarios. (U.S. Air Force photo/Samuel King Jr.)
