An Airman receives a demonstration on the proper use of an M84 flashbang during a response force tactical course Mar. 27, 2019, at the 90th Ground Combat Training Squadron, Camp Guernsey, Wyo. This distractionary device is a less than lethal ammunition grenade that helps to distract and cause chaos and allows security forces to make it through the door safely and gain control of a situation.
