What type of operation involves air evacuation?

The operation that involves air evacuation is best described by the term "Assault Support." This type of operation typically includes a variety of mission categories that aim to transport personnel and equipment using rotary-wing and fixed-wing aircraft. Within this context, air evacuation is a critical function, enabling the swift movement of injured personnel from the battlefield or other hazardous environments to medical facilities.

In contrast, while Tactical Recovery of Aircraft and Personnel focuses on recovering downed pilots or aircraft in hostile situations, it may not primarily emphasize evacuation as a standalone concept. Combat Assault Transport generally pertains to the process of aerial deployment of troops and equipment into combat zones but does not specifically denote air evacuation. Lastly, air delivery focuses on the aerial dropping of supplies and equipment rather than the evacuation of personnel. Therefore, "Assault Support" is the most encompassing term regarding operations that include air evacuation.
