Medevac vs casevac: the difference

Reviewed by the AirAmbulance.org editorial team · Updated 6 November 2026 · Editorial policy

Medevac and casevac both move casualties to care, but a medevac uses a dedicated, medically equipped vehicle with care on the way, while a casevac uses whatever transport is available.

Medevac

• Dedicated medical aircraft or vehicles with trained medical crews and equipment.
• In military use, often marked as medical and requested with a standard format such as the '9-line' medevac request.

Casevac

• Casualty evacuation using non-dedicated transport, such as a utility helicopter or vehicle.
• Used when speed matters more than having medical equipment on board, or when no medevac is available.

In civilian life

• Civilian air ambulances are the equivalent of medevac: dedicated aircraft with medical crews.
• The terms come mainly from military and disaster-response use.

The core difference

• MEDEVAC (medical evacuation) uses dedicated, equipped aircraft or vehicles with a medical crew who care for the patient during the move.
• CASEVAC (casualty evacuation) uses whatever transport is available, often without dedicated medical equipment or en-route care, because there's no time to wait.

Where the terms come from

• Both are military terms. In civilian use, 'medevac' is often used loosely for any air ambulance flight or medical evacuation.

Why it matters to civilians

• A civilian air ambulance is a medevac: a dedicated aircraft with a medical crew and equipment.
• When families or insurers say 'medevac', check whether they mean an air ambulance, a medical escort on a commercial flight, or a move to the nearest hospital.
