# 177th Armored Brigade (United States)

The 177th Armored Brigade is an AC/RC unit based at Camp Shelby, Mississippi. The unit is responsible for training selected United States Army Reserve and National Guard units. The unit was formerly designated as 3rd Brigade, 87th Division. The brigade is a subordinate unit of First Army.
The brigade has been re-designated and re-missioned several times:
* During the World War I, the Brigade was infantry and fought as part of the 89th Infantry Division.
* In 1986, the Brigade assumed the mission as the Opposing Force (OPFOR) at the National Training Center (NTC) at Fort Irwin, California. The Brigade consisted of 2 battalions: 6th Battalion, 31st Infantry (6–31 IN) and 1st Battalion, 73rd Armor (1–73 AR). On the NTC battlefield, the 177th portrayed the fictitious, Guards 60th Motorized Rifle Division, which was based upon Soviet Army structure and doctrine.
* In 1988 the Brigade re-designated several units and activated others. 6–31 IN became 1–52 IN, 1–73 AR became 1–63 AR. Activated were the 177th Support Battalion, 177th Military Intelligence Company, 164th Chemical Company and the 87th Engineer Company.
