United States Air Force Combat Control Team

The United States Air Force Combat Control Teams, singular Combat Controller (CCT) (AFSC 1Z2X1), are an elite special operations force (specifically known as "special tactics operators") who specialize in all aspects of air-ground communication, as well as air traffic control, fire support (including rotary and fixed-wing close air support), and command, control, and communications in covert, forward, or austere environments. Assigned to Special Tactics Squadrons and Special Tactics Teams along with Pararescuemen, Special Operations Reconnaissance, and Tactical Air Control Party (TACP) operators, Combat Controllers are an integral part of Air Force Special Operations Command (AFSOC), the Air Force component of United States Special Operations Command (USSOCOM), and of Joint Special Operations Command (JSOC).
