_____ is the authority to control the maneuver of and grant weapons release clearance to attacking aircraft.

Terminal Attack Control (TAC) is the authority responsible for directing the engagement of attacking aircraft and granting them clearance to release their weapons. This role is crucial in ensuring the effectiveness and safety of air support, particularly in close support environments where ground forces may be operating in proximity to enemy targets. Terminal Attack Controllers coordinate with pilots and ground units to establish targets, disseminate clear instructions, and ensure that air strikes do not jeopardize the safety of friendly forces.

In contrast, Close Air Support (CAS) refers to the air action against hostile targets that are in close proximity to friendly forces, but it does not inherently include the authority to control maneuver or grant weapon release. Close Combat Attack (CCA) refers to operations that involve the direct engagement of targets that are near friendly forces, but like CAS, it does not specify the control and clearance aspect attributed to TAC. Tactical Risk Assessment (TRA) involves evaluating the risks associated with potential actions but does not encompass the authority to control aircraft or approve weapon releases. Thus, TAC is the correct term that captures the essential authority and operational responsibility in this context.
