U.S. Air Force pararescuemen assigned to the 48th Rescue

U.S. Air Force pararescuemen assigned to the 48th Rescue Squadron prepare to retrieve a simulated patient during a mass casualty exercise at Davis-Monthan Air Force Base, Ariz., April 14, 2015. For this exercise, several D-M Airmen volunteered to play victims. This element added realism to the training, allowing the pararescuemen to work through the stress that each mission can bring. Due to security concerns, the last name is withheld. (U.S. Air Force photo by Senior Airman Betty R. Chevalier)
