A United States Air Force Tactical Air Control Party, commonly abbreviated TACP, refers to an individual or team of United States Air Force personnel with AFSC 1C4X1, who are aligned with a conventional United States Army or United States Marine Corps combat maneuver unit or to an Air Force, Army, Marine, or Navy special operations unit, to provide precision terminal attack guidance of U.S. and coalition fixed- and rotary-wing close air support aircraft, artillery, and naval gunfire; establish and maintain command and control (C2) communications; and advise ground commanders on the best use of air power.
In conventional settings, TACPs are the principal Air Force liaison element to the United States Army (USA). In this context, the TACP is an Air Force liaison element aligned with Army combat maneuver echelons from Corps to Battalion level. The TACP provides its aligned Army unit with expertise in planning and executing airpower in support of the land component commander's scheme of maneuver. In special operational settings, TACPs deploy with special operations units, including Air Force Special Tactics, Army Special Forces, and Navy SEAL teams, the 75th Ranger Regiment, and Joint Special Operations Command Special Mission Units, acting primarily as precision airstrike controllers and communication/C2 experts.
