Brigade Headquarters was inactive through World War II after the US Army reorganized its Divisions from 2 brigades of 2 regiments (the Square Division), into one of 3 regiments with no brigades (the Triangular Division) concept.
The brigade was organized as a separate Infantry Brigade at Schofield Barracks, Hawaii as the first element of the 6th Infantry Division. The 6th Infantry Division was scheduled to be activated for deployment to Vietnam but Secretary of Defense McNamara cancelled its activation. The 11th Infantry Brigade was deployed, and during the Vietnam War served in the United States Army's 23rd Infantry Division (called the Americal Division). Elements of the Brigade were responsible for the My Lai massacre where members of the brigade's 1st Battalion, 20th Infantry Regiment murdered between 340 and 500 civilians in 1968.
