KEESLER AIR FORCE BASE, Miss. -- Reservists of the 815th Airlift Squadron took time before a May exercise at Volk Field, Wis. to catch up on their Mission Oriented Protective Posture familiarization. Donning aircrew ensembles, nearly 20 people processed through a Containment Air Processing System set up outside the squadron. The CAPS is a series of stations used in a chemical environment to minimize the possibility of contamination when Airmen exit a contaminated area and need to remove their MOPP gear. At each station an attendant assists and provides guidance on how to remove the gear. Lt. Col. Brian Freeman prepares to remove his chemical protective mask with help from Senior Airman Johnny Woodland, a loadmaster with the unit. (U.S. Air Force Photo/Airman 1st Class Lindsay Boggan)
