What is the definition of Close Air Support?

Close Air Support (CAS) is defined specifically as support missions that require the integration of air operations with ground forces to engage enemy targets that are in close proximity to friendly troops. This type of air support is essential for ensuring that air strikes can be conducted effectively without endangering friendly units.

The emphasis on integration with ground forces highlights the coordinated nature of these missions, which often involves real-time communication between pilots and ground controllers. This ensures that attacks are accurate and timely while minimizing the risk of collateral damage.

In contrast, options describing air actions against targets far from friendly forces or focusing solely on high-value enemy targets do not align with the CAS definition, as they lack the critical aspect of proximity and the necessity for integration with ground troops. Logistical support from air units also diverges from the concept of close air support, as it pertains more to supply and resupply missions rather than engaging enemy forces in support of combat operations.
