What type of rescue does CAD stand for in search and rescue?

In the context of search and rescue operations, CAD typically does not represent any specific or recognized acronym related to the choices provided. Rather, CAD in this sense refers to concepts that do not align with standard terminology used in search and rescue.

Specifically, Coastal Air Deployment, Cadaver Air Deployment, and Cave Air Deployment are not officially recognized terms within the search and rescue community. The military and civil agencies involved in these operations use a variety of acronyms and terminologies, but none of these options are widely accepted or utilized in professional contexts. Therefore, the choice of "None of the above" accurately reflects the fact that CAD does not correspond to any known type of rescue operation. Recognizing the proper terminologies and avoiding confusion around incorrect acronyms is essential for effective communication in emergency situations.
