What does CAS stand for in military terminology?

In military terminology, CAS stands for Close Air Support. This refers to the tactical use of aircraft to provide support to ground forces engaged in combat. Close Air Support is critical in battlefield scenarios as it allows for real-time assistance to troops in contact with the enemy. The intent is to strike targets in close proximity to friendly forces while minimizing the risk of collateral damage.

CAS involves coordination between ground units and air support, ensuring that aircraft can provide effective firepower when it is most needed, such as in situations where troops are outnumbered or in dire circumstances. The success of CAS is heavily reliant on communication and situational awareness so that aircrews can accurately engage enemy forces while keeping friendly personnel safe.

The other options listed do not accurately represent what CAS stands for in a military context. Combat Air Service, Controlled Area Security, and Critical Asset Safety refer to different concepts and are not commonly recognized acronyms associated with close air operations.
