On April 14, 1961 the Air Force Tactical Air Command (TAC) activated the 4400th Combat Crew Training Squadron at Hurlburt, to fly operations against guerrillas, either as an overt Air Force operation or in an undefined covert capacity. Known by its nickname "Jungle Jim", the unit was commanded by Colonel Benjamin H. King. The squadron was authorised 16 C-47s, eight B-26s and eight T-28 Trojans, plus the same number of aircraft in temporary storage. The T-28s were armed with .50 calibre mg, 2.75-in. rockets and a small quantity of bombs. These specialists flew missions in Africa, Southeast Asia, Central America and other places throughout the world. In early 1962, plans for the never executed Operation Northwoods called for decoy aircraft to land at this base.
