Colton Monnin, 81st Medical Operations Squadron medical technician, as he portrays a "victim" during a mass casualty and response exercise on Keesler Air Force Base, Mississippi, April 17, 2019. The scenario for the two-day event included a simulated plane crash with debris landing both on and off base in crowds of people. The exercise tested base and local civilian emergency response organizations' ability to operate in a multi-agency and multi-jurisdiction crisis situation. (U.S. Air Force photo by Kemberly Groue)
