Airmen from the 87th Medical Group place an automated external defibrillator on a role player during a simulated medical emergency at Joint Base McGuire-Dix-Lakehurst, N.J., March 7, 2012. Mobility Airmen from the 817th Contingency Response Group, 87th MDG and Detachment 307 of the Air Force Office of Special Investigations worked together to simulate the emergency evacuation of American citizens ahead of a volcanic eruption. The NEO, or noncombatant evacuation operation, is a mission the CRW has never performed, and adds a new capability to the Contingency Response Wing’s toolset. (U.S. Air Force photo/Tech. Sgt.
