Farm Gate was the codename for an American air force mission in Vietnam.
In the early 1960s, the US armed forces were developing units specifically designed to counter guerrilla warfare. The first unit in the USAF of this nature was the 4400th Combat Crew Training Squadron code named "Jungle Jim" that were later renamed the 1st Air Commando Group after the same unit who served in the China Burma India Theatre of World War II. The squadron specialized in tactics used to support friendly ground forces in small, brush fire conflicts. In October 1961, John F. Kennedy authorized the deployment of a detachment of Air Commandos to South Vietnam. The 4400th CCTS headed from their home at Eglin AFB to SE Asia. Their mission was to train the VNAF using older aircraft in support of the type of conflict they were facing. Crews were trained to fly the T-28 Trojan, C-47 Dakota and B-26 Invader. The codename for the 4400th CCTS and its mission was Farm Gate.[1]
While the aircraft involved in the Farm Gate operation were often piloted by American "advisers," for training purposes, it was required by Washington that a South Vietnamese national be part of the crew aboard any combat missions. In the event an aircraft did get shot down in hostile territory, the presence of an Asian crewman would be enough to dodge any accusations of Geneva Accord violations. The interpretation of this regulation was somewhat liberal however. There were some reports of hapless South Vietnamese enlisted men being thrown into the back seats of T-28s and flown into combat by American pilots after having been told not to touch anything in the cockpit. After the escalation of the war as a result of the Gulf of Tonkin Incident, the Farm Gate detachment was no longer required to fly under South Vietnamese colors. Their aircraft began carrying full US markings and the detachment became known as the 1st Air Commando Squadron (and later as the 1st Special Operations Squadron).
