CASEVAC refers to which of the following?

• A. Transport by medical personnel of wounded, injured, or ill persons from battlefield and/or other locations to Medical Treatment Facilities
• B. Unregulated movement of casualties aboard nonmedical aircraft, vehicles, or maritime vessels
• C. Immediate medical evacuation by helicopter only
• D. Casualty treatment in place

Answer: (A)

Moving wounded or ill personnel to a Medical Treatment Facility under medical supervision is what CASEVAC refers to here. The idea is evacuation to a place where they can receive formal medical care, with medical personnel involved in the transport and care along the way. This best fits the concept because it centers on conveying casualties to treatment facilities rather than on-site care, unregulated transfers, or exclusive helicopter moves.

So, the preferred choice highlights evacuation to care with medical oversight. The other scenarios describe things that either lack medical supervision, are limited to a specific transport type, or involve treating casualties without moving them to a facility.
