During the Berlin Wall Crisis of 1961, the Army reorganized the command structure of the forces in Berlin and created the U.S. Army Berlin and created the Berlin Brigade from the units already in the city. The 6th Infantry Regiment, active in Germany since 1950, was reorganized in mid-1958 according to the Pentomic structure: Each battle group consisted of five line (rifle) companies, a combat support company, and a headquarters &amp; headquarters company. The Berlin Brigade had the 2nd and 3d Battle Groups, 6th Infantry until 1963, when Army force structure abandoned battle groups in favor of brigades and subordinate battalions.
