Members of the 341st Missile Security Operations Squadron convoy response force demonstrate the proper use of a tourniquet to stop the bleeding of a lower leg wound during a Tactical Combat Casualty Care simulation training exercise as part of Operation Frozen Hell, Jan. 12, 2021, at Malmstrom Air Force Base, Mont. Airmen are taught to apply the tourniquet to the injured area as “high and tight” as possible to halt excessive blood loss. (U.S. Air Force photo by Airman Elijah Van Zandt)
