Two members of the 95th Medical Group’s In-Place Patient Decontamination Team at Edwards Air Force Base, Calif., work to decontaminate their “patient” with soap and water, hoping to remove a simulated persistent chemical agent. The team spent three days, March 15 to March 17, 2011, undergoing training and instruction on chemical agents and proper decontamination procedures. (Air Force photo/Kate Blais)
