Tactical Combat Casualty Care (TCCC) is an All Service Members Course (AMS) that teaches service members lifesaving skills to render basic medical aid to a trauma casualty. The five lifesaving skills learned are: rapid casualty assessment, tourniquet application, wound packing with a hemostatic dressing, application of a pressure bandage, and basic airway maneuvers to open the airway. The Secretary of Defense has directed that all military service members be trained and become proficient in basic lifesaving TCCC AMS skills, replacing the Combat Lifesaver course.
