Army Reserve Soldiers of the 409th Engineer Company, Windsor, Colorado, move a simulated casualty onto a stretcher during Guardian Response 22, held at Muscatatuck Urban Training Center, April 29. The casualty represented a victim that had been trapped under the wheels of a bus following a building explosion in an urban environment. To be successful, the unit was required to evaluate the chemical threat of the environment, asses and stabilize the casualty, extract the casualty from under the bus, then transport the casualty to a chemical decontamination and treatment facility operated by the Army Reserve’s 371st Minimal Care Detachment, Twinsburg, Ohio.
