The 181st Infantry Brigade is an infantry brigade of the United States Army based at Fort McCoy, Wisconsin. As an Active Component/Reserve Component (AC/RC) brigade, the unit serves primarily in a training role for other units of the US armed forces. The brigade is subordinate to the First United States Army, headquartered at Rock Island Arsenal, Illinois.[2] It has six prime components.[3]

The unit is responsible for training selected United States Army Reserve and Army National Guard units in the Central-Northern United States. The unit was formerly designated as 2nd Brigade, 85th Division. The brigade was redesignated and re-missioned several times: such as in 1999, when the 181st was merged with the 2nd Brigade, 85th Division and carried that name and lineage. The 181st Infantry Brigade currently falls under the 1st Army's Division West, headquartered at Fort Hood, Texas.

During World War I, the 181st Infantry Brigade was constituted 5 August 1917[7] in the National Army at Camp Lewis, Washington as a subordinate unit of the 91st Infantry Division.[2] The Brigade was composed of 8,134 personnel organized in a Headquarters Detachment with 5 Officers and 18 Enlisted Soldiers, the 361st and 362nd Infantry Regiments each with 3,755 Officers and Enlisted Soldiers, and the 347th Machine Gun Battalion with 581 Officers and Enlisted Soldiers.[8] The 181st Infantry Brigade trained for 10 months at Camp Lewis prior to being deployed to France in August 1918.[9] After the Meuse-Argonne Offensive and the liberation of France, the Brigade was sent to assist the British with quelling the German Army’s final gasps at Ypres-Lys until the signing of the Armistice on 11 November 1918, which ended World War I. After four months of peacekeeping operations in liberated Belgium, the Brigade returned to the United States and arrived at the port of New York on 2 April 1919 on the U.S.S. Orizaba. [9]

The Brigade was redesignated Headquarters & Headquarters Company (HHC), 181st Brigade on 23 March 1925 and again redesignated HHC, 181st Infantry Brigade on 24 August 1936. The unit conducted summer training most years at Del Monte, California, from 1922–40.
