The objective of Search and Rescue (SAR) as described in the National Search and Rescue Manual is to aid persons and property in distress. This objective reaches the pinnacle of importance in its application to combat SAR (CSAR). The hazards of the wartime environment dictate that CSAR forces must be specifically equipped, trained, and organized for the wartime mission. This regulation prescribes combat search and rescue procedures approved by the Joint Chiefs of Staff.
