This MTTP, Army Techniques Publication ATP 3-52.4 Multi-Service Tactics, Techniques, and Procedures for Air Control Communication October 2024, establishes communications tactics, techniques, and procedures (TTP) for tactical command and control (TAC C2) to manage air operations and to control airspace and aircraft. It also establishes TTP for force packaging and direct air support coordination, air-to-air (A/A) communication, A/A intercept, threat A/A warning, threat surface-to-air warning, and air-to-surface communication. This publication provides MTTP for the control and coordination of air operations in TAC C2 managed joint operations area (JOAs) or battle management areas (BMA). This MTTP publication applies to all TAC C2 airspace control elements and warfighters that conduct air operations in JOAs or BMAs managed by the joint force commander (JFC) and overseen by the airspace control authority in accordance with the JFC signed airspace control plan (ACP) and airspace control order (ACO).Operational planners and exercise planners can use this publication to inform the ACP, ACO, the special instructions, the area air defense plan, and rules of engagement. This publication addresses an avenue for the Services to tap into the intelligence, surveillance, and reconnaissance constellation. It provides TTP to leverage current intelligence from platforms like RQ-4; RC-135; U-2; unmanned aircraft systems (UASs); space; and cyberspace by contacting the TAC C2. The TAC C2 may be manned by the United States (US) Air Force, Navy, or Marine Corps. TAC C2 would provide the current, consolidated battlespace picture.
