 The brigade was formed again in 1950 when it was hastily assembled for service in the Korean War. The brigade participated in a counterattack at Masan before reinforcing United States Army units during the Battle of Pusan Perimeter, and at the First and Second Battles of Naktong Bulge along the Naktong River. The brigade was deactivated for the last time when it was merged with the 1st Marine Division.
