Casualty evacuation is movement from initial Level 1 care often provided by the field medic or corpsman to a forward surgical team. Overwhelmingly this job is done by the Army and the Navy and it is a daunting task. They must use a vehicle of opportunity or secure a safe landing zone for a rotary aircraft and provide care under fire until this can be achieved. The mission is paramount and must be completed. The only time CCATT has been involved in this situation is during work with Special Operations Forces in Afghanistan.
