As of July 2006, the 155th separate Armored Brigade was scheduled to be made part of the 36th Infantry Division as the 155th Armored Brigade Combat Team. This restructuring would be part of the National Guard's modularization process.
The 155th separate Armored Brigade (Heavy) takes it's name from the 155th Infantry Regiment which dates back to 1798.
During its history, the 155th Infantry has served under such notable leaders as Andrew Jackson and Jefferson Davis, and participated in the battles of the War of 1812, the United States Civil War, the Spanish American War, World War One and Two, and mobilized for Desert Shield/Storm.
While the units assigned to the 155th Armored Brigade vary in length of service, the brigade itself dates back to April 1951 when it was organized as Headquarters, Company 108th Armored Cavalry Regiment. In 1968 the 108th became part of the 30th Armored Division and re-designated as the First Brigade, 30th Armored Division.
In 1973 the brigade was redesignated as the 155th Armored Brigade when the 30th Amored Division was broken up into separate brigades.
The 155th Separate Armored Brigade (Heavy) is an asset of the Mississippi Army National Guard, and is an integral part of the Total Army Concept.
The first Annual Training period involving members of the 155th Separate Armored Brigade (Heavy) for 2001 took place when the unit participated in the 18th Airborne Corps Warfighter Exercise at Fort Campbell, KY, for the periods of 27 January-03 February and 27 February-11 March 2001.
The Adjutant General's Office of the Mississippi National Guard received an alert notification in May 2004 for the nearly 4,000 soldiers of the 155th Separate Armored Brigade (SAB), headquartered in Tupelo, Miss. The notification alerts the command of the brigade and its units to begin sensible planning and preparation for possible mobilization in support of Operation Iraqi Freedom.
