A search and rescue team Soldier of the Army Reserve’s 409th Engineer Company, Windsor, Colorado, scans for chemical contamination at the site of a simulated casualty during Guardian Response 22, held at Muscatatuck Urban Training Center, April 29. Teams were evaluated by Observer-Controller-Trainers (background), who communicated conditions of the scene and specific injuries to casualties in which the team was required to respond. To be successful in the scenario, teams needed to evaluate the chemical threat of the building, locate and asses casualties, determine how to safely remove the casualties from the scene and then evacuate to a chemical decontamination and treatment site operated by the Army Reserve’s 371st Minimal Care Detachment, Twinsburg, Ohio.
