199th Light Infantry Brigade
The 199th Light Infantry Brigade was formed at Fort Benning, Georgia, in 1966, and arrived in South Vietnam that December. The 199th assumed responsibility for Operation Fairfax, defending the approaches to Saigon, until late 1967. In December 1967, the brigade undertook Operation Uniontown, a sweep into War Zone D (Iron Triangle) near Bien Hoa. During the Tet Offensive, the brigade defended Bien Hoa airfield together with the Long Binh post complex and the headquarters of II Field Force Vietnam. However, elements of the brigade were used to recapture the Pho Tho racetrack in Saigon and, together with other American and South Vietnamese troops, held the area during two days of house-to-house fighting. During most of 1968, the 199th Light Infantry Brigade continued to patrol the area around Bien Hoa in support of a series of joint American-Vietnamese operations known as Operation Toan Thang ("Total Victory"). The brigade also supported the invasion of Cambodia (Operation Binh Tay) in May 1970. The 199th Light Infantry Brigade was withdrawn from South Vietnam in the fall of 1970 and was deactivated at Fort Benning in October. The 199th sustained more than 3,200 casualties during its stay in South Vietnam.
