What is defined as air action against hostile targets near friendly forces?

Close Air Support refers to air action conducted against hostile targets that are in proximity to friendly forces. The primary objective of Close Air Support is to provide immediate and direct assistance to ground troops engaged in combat. This type of air operation is crucial, as it requires coordination between air and ground forces to ensure that strikes on enemy targets do not inadvertently affect friendly personnel. The emphasis is on the support aspect, highlighting the importance of protecting troops while engaging the enemy effectively.

In contrast, Air Interdiction is focused on attacking enemy targets further back in their territory to disrupt their operations, while Combat Search and Rescue involves recovering personnel in danger, and Intelligence Surveillance Recon deals with gathering information rather than direct combat support. Close Air Support is uniquely characterized by its proximity to friendly forces and the immediate need for air support in a dynamic combat environment.
