It trained at Fort Benning and Camp Shelby, Mississippi from September to November 1966 in preparation for deployment to South Vietnam from Fort Benning. The 199th was the only combat unit to train at Camp Shelby during the Vietnam War.
Nicknamed "the Redcatchers", the unit was hastily moved to Sông Bé, Vietnam on 10 December 1966 to provide an increased U.S. presence in the III Corps Tactical Zone and remained there until its return to Fort Benning on 11 October 1970.
The brigade was conducting Operation Uniontown in Đồng Nai Province when the 1968 Tet Offensive began. It immediately began a defense of U.S. II Field Force headquarters at Long Binh Post against attacks by the VC 275th Regiment. One battalion was moved by helicopter to attack a Vietcong command post at the Phu Tho racetrack inside Saigon, then engaged in house-to-house fighting in Cholon.
During 1969, the 199th was responsible for the security of the region north and east of the capital, and in 1970 moved into the "Iron Triangle" when other units participated in the Cambodian Incursion.
