What defines close air support (CAS) in LSCO?

Close air support (CAS) in large-scale combat operations (LSCO) is specifically defined as air operations that provide direct support to ground forces engaged in combat. This involves aircraft delivering munitions and conducting missions that are closely coordinated with ground units to effectively neutralize enemy threats, ideally without causing collateral damage to friendly forces.

The process emphasizes the immediate and tactical nature of the support, highlighting the importance of real-time coordination and communication to ensure that air strikes occur precisely where needed in relation to friendly troops. CAS is fundamentally about synchronizing airpower with ground maneuvers to achieve desired tactical outcomes and protect friendly forces actively engaged in combat.

This distinct functionality of CAS stands in contrast to other types of air support or operations, which might involve indirect assistance, broader strategic objectives, or logistical support that do not focus directly on immediate ground engagements.
