What is the primary purpose of "combat search and rescue" (CSAR) missions?

The primary purpose of combat search and rescue (CSAR) missions is to recover personnel who are isolated or in distress, particularly in hostile environments. This involves retrieving military personnel, such as pilots or special forces members, who may have been shot down, stranded, or otherwise cut off from friendly forces. CSAR emphasizes the importance of ensuring the safety of personnel in dangerous situations, which is critical for maintaining morale and operational capability within military operations. These missions often require specialized skills, tactics, and equipment tailored to operate under the threats posed by enemy forces, making them distinct from other military support functions like intelligence gathering, logistical support, or disruption of supply lines.
