The 196th served in Vietnam from 15 July 1966 through 29 June 1972.

The Brigade was reactivated in September 1965 at Fort Devens Massachusetts, where it was originally scheduled to be sent to the Dominican Republic. Instead the Army rushed it to Vietnam, the Brigade departing on 15 July 1966 via transport ships and arriving on 14 August 1966 at Tây Ninh Combat Base. It began operations almost immediately in the western area of III Corps Tactical Zone. The 196th conducted Operation Cedar Falls, Gadsden, Lancaster, Junction City, Benton, and Attleboro (in War Zone C of Tay Ninh Province). Attleboro turned into a major action after a large enemy base camp was found on 19 October 1966.

In February 1967, Gen. William Westmoreland ordered the formation of a division sized Army task force to reinforce American forces in I Corps Tactical Zone. The 196th was selected to form a part of the task force. Task Force Oregon became operational on April 20, 1967, when troops from the 196th landed at Chu Lai in I Corps. Over the next month, it was joined by the 1st Brigade of the 101st Airborne Division and the 3rd Brigade of the 25th Infantry Division (later redesignated the 3rd Brigade, 4th Infantry Division). On 25 April 1967 Task Force Oregon was redesignated the 23rd Infantry Division (Americal) and an official change of colors ceremony was held on 26 October 1967.[2] Later, the 1st Brigade, 101st Airborne and the 3rd Brigade, 25th Infantry Division were replaced by the 198th and 11th Light Infantry Brigades.

As part of the 23rd, the 196th participated in Operations Wheeler/Wallowa, Golden Fleece, Fayette Canyon, Frederick Hill, Lamar Plain, Elk Canyon I and Elk Canyon II. In early May 1968, the 2-1 Infantry of the 196th was flown in to assist at the Battle of Kham Duc. On 29 November 1971, the 196th became a separate temporary entity to safeguard this same area of operations.

In April 1971, the 196th moved to Da Nang to assist in port security duties, and finally left Vietnam on 29 June 1972 as the last combat brigade to leave in Vietnam. The brigade suffered 1,188 KIA, and 5,591 WIA in Vietnam.
