The CSH will generally have a ground ambulance company attached. This company consists of approximately four platoons of ground ambulances commanded by a Medical Service Corps officer. The ground ambulance company in cooperation with available air ambulances (MEDEVAC) is responsible for the movement of sick and wounded from the battalion aid station and other forward-deployed locations to the CSH, as well as evacuation through an established medical treatment chain leading ultimately, for those seriously sick or wounded, to hospitals in the Continental United States in cooperation with resources in the U.S. Air Force.
