Defenders from the 28th Security Forces Squadron carry a fellow Airman with a simulated injury to a medical treatment facility during the Phase II portion of an operational readiness exercise at Ellsworth Air Force Base, S.D., July 11, 2013. Airmen are trained on self-aid and buddy care annually, and sometimes more frequently, to ensure they stay up to date on the most current and effective life-saving procedures that could become necessary during real world contingencies.
