The 1st Armored Division Sustainment Brigade is a sustainment brigade of the United States Army based at Fort Bliss, Texas. It provides logistics support to the 1st Armored Division.
The brigade's lineage dates back to 1919, and it had a long and decorated history when designated as the supply command of the 1st Cavalry Division. Having seen service in every major conflict of the 20th century in support of its parent division, the unit was not designated as the 15th Sustainment Brigade permanently until 2005. In February 2008, the brigade was reassigned to the 13th Sustainment Command (Expeditionary), ending almost a century of association with the 1st Cavalry Division.
The 15th Sustainment Brigade's extensive lineage also carries many honors for the unit. What is now the 15th Sustainment Brigade, and its previous incarnations, have earned 17 campaign streamers, as well as numerous awards, mostly for service during the Vietnam War. These decorations include the Presidential Unit Citation, the Valorous Unit Award, and five Meritorious Unit Commendations.
