Close air support (CAS) is a military tactic where aircraft provide direct assistance to ground forces engaged in combat. This support is typically used to target enemy troops, vehicles, or fortifications that are in close proximity to friendly forces. The goal is to enhance the effectiveness of ground operations while minimizing the risk of collateral damage. CAS missions often involve coordination between ground troops and pilots to ensure accurate targeting. This can include the use of various aircraft, such as attack helicopters or fighter jets, which are equipped with precision-guided munitions. Effective communication is crucial to ensure that air support is delivered safely and effectively.
