Dustoff or colloquially Dust Off, is a military term for the emergency
patient evacuation of
casualties from a combat zone. Casevac can be done by both ground and air. "DUSTOFF" is the callsign specific to U.S. Army Air Ambulance units. CASEVACs by air today are almost exclusively done by helicopter, a practice begun on a small scale toward the end of

The primary difference between a CASEVAC and a
medical evacuation
Medical evacuation, often shortened to medevac or medivac, is the timely and efficient movement and en route care provided by medical personnel to patients requiring evacuation or transport using medically equipped air ambulances, helicopters and ...
(MEDEVAC) is that a MEDEVAC uses a standardized and dedicated vehicle providing en route care, while a CASEVAC uses non-standardized and non-dedicated vehicles that may or may not provide en route care. CASEVACs are commonly referred to as "a lift/flight of opportunity". If a corpsman/medic on the ground calls for a CASEVAC, the closest available unit with space could be called to assist, regardless of its medical capabilities. This could include U.S. Marine Corps aircraft such as the
MV-22 Osprey, U.S. Navy
SH-60 Seahawk helicopters, or
CH-46 Sea Knight helicopters. The guiding principle in a CASEVAC is to transport casualties that are in dire need for evacuation from the battlefield and do not have time to wait on a MEDEVAC. MEDEVAC aircraft and ground transport are mandated by the Geneva Convention to be unarmed and well marked. Firing on "clearly marked and identified" MEDEVAC vehicles would be considered a war crime under Article II of the

"Dust Off" was the tactical call sign for medical evacuation missions first used in 1963 by Major Lloyd E. Spencer, commander of the U.S. Army
57th Medical Detachment (Helicopter Ambulance). It became famous after an article by journalist
Peter Arnett described the death of Spencer's successor in command, Major
Charles L. Kelly, on 1 July 1964 and his dying words, "When I Have Your Wounded." The name was used by all Army medical evacuation units except one in the remainder of the war and continues to be used today by Army medical evacuation units. Typically air ambulances transport wounded soldiers categorized as "urgent" patients from point of injury to a medical facility within an hour of soldier(s) being wounded. Flying into an active landing zone to pick up wounded was a dangerous job. Peter Dorland and James Nanney wrote in ''Dust Off: Army Aeromedical Evacuation in Vietnam'', "... slightly more a third of the aviators became casualties in their work, and the crew chiefs and medical corpsmen who accompanied them suffered similarly. The danger of their work was further borne out by the high rate of air ambulance loss to hostile fire: 3.3 times that of all other forms of helicopter missions in the Vietnam War."
All members of the US Armed Forces today are trained in some form of basic first aid. While lacking advanced life saving equipment and medical personnel in regular vehicles, all personnel today enter the combat zone with an Improved First Aid Kit (IFAK) on their equipment. The IFAK has basic medical supplies such as bandages, a

Tactical Combat Casualty Care.
The U.S. military has worked to ensure dedicated MEDEVAC platforms with trained medical personnel are available in the event of a casualty. This has, in part, led to a 90.6% casualty survival rate (numbers from operations in Afghanistan and Iraq, 2006), compared to 80.9% in
