Which term describes the process of evacuating casualties?

The term that describes the process of evacuating casualties is CASEVAC. This is a specific term used in military and emergency contexts to refer to the evacuation of casualties from the point of injury to a medical facility. It emphasizes the urgency and logistical aspects involved in moving injured individuals to receive necessary medical care.

In contrast to other terms, CASEVAC is focused specifically on medical evacuation, while other options refer to different concepts. For instance, CAS refers to Close Air Support, which involves air missions in support of ground forces but does not pertain to casualty evacuation. CO2 is a chemical compound and is unrelated to medical or evacuation processes. Lastly, CRRC stands for Combat Rubber Raiding Craft, which is a type of inflatable boat used for various operations but not specifically for evacuating casualties. Understanding the specifics and context of these terms helps clarify why CASEVAC is the correct choice for describing the evacuation of casualties.
