The mission of the 1st Sustainment Brigade, 1st Infantry Division (Mechanized) is to plan, synchronize, monitor, and execute distribution operations. It also has the mission of conducting sustainment operations within assigned area of operation, conducting Theater Opening and/or Theater Distribution operations when directed, and providing support to joint, interagency, and multinational forces as directed.

The 1st Sustainment Brigade, 1st Infantry Division (Mechanized) traces its origins to World War I, where in 1917, the Division Trains were formed to support the newly formed 1st Infantry Division. In 1921, the Division trains were consolidated into the Special Troops, 1st Infantry Division. After World War I, the Special Troops deployed to Fort Riley, Kansas. Three battalions that subsequently became part of the Division Support Command (DISCOM), 1st Infantry Division, the 101st and 201st Forward Support Battalions, and the 701st Main Support Battalion, served in World War I, but with different divisions.

Division support units deployed back to Germany to support the 1st Infantry Division during World War II, and participated in all 8 campaigns credited to the 1st Infantry Division. In 1955, the Division and its support organizations returned to Fort Riley, Kansas.

In 1965, the 1st Infantry Division deployed to the Republic of South Vietnam, marking the third time during the 20th century that the Division participated in armed conflict. DISCOM units supported the Division in all of the 11 campaigns it participated in while deployed to South Vietnam.

After Vietnam, the DISCOM underwent many changes. The Division Material Management Center (DMMC) was established, and the Finance and Personnel Services Companies (PSC) were reorganized into battalion commands. In 1990, the DISCOM deployed again, this time to Southwest Asia in Support of Operation Desert Storm.

In 1996, the DISCOM, deployed to Europe for a third time, with the 101st Forward Support Battalion at Fort Riley, Kansas, the 201st Forward Support Battalion in Vilseck, Germany, the 701st Main Support Battalion in Kitzingen, Germany, and the Headquarters and Headquarters Company also in Kitzingen.

In 2003, the DISCOM was deployed to Turkey in support of Operation Iraqi Freedom I. The DISCOM simultaneously supported peacekeeping operations in the Balkins and deployed a logistics task force to support Operation Iraqi Freedom I throughout Iraq. In 2004, the DISCOM redeployed to Southwest Asia in Support of Operation Iraqi Freedom II. In addition to the organic DISCOM units, the 225th Forward Support Battalion from Hawaii and the 230th Support Battalion from North Carolina deployed to support logistical operations for Task Force Danger. Finally, in 2005, the DISCOM redeployed to Germany to reconstitute and prepare for future contingency operations. The DISCOM was awarded the Meritorious Unit Commendation for its contributions during Operation Iraqi freedom II.

As of January 2006, the DISCOM consisted of the 201st Forward Support Battalion in Vilseck, Germany, the 701st Main Support Battalion in Kitzingen, Germany, the 299th Forward Support Battalion in Schweinfurt Germany, the 601st Aviation Support Battalion in Katterbach Germany, and the Headquarters and Headquarters Company also in Kitzingen. Between January 2006 and July 2006 the 701st Main Support Battalion was inactivated, the 299th was task organized to the 2nd Brigade Combat Team in preparation for another deployment to Operation Iraqi Freedom, and the 201st Foward Support Battalion was task organized under the 3rd Brigade Combat Team and later inactivated.

The DISCOM Headquarters and Headquarters Company was re-deployed to Fort Riley Kansas in August 2006 to build the 1st Sustainment Brigade. At the time, its subordinate units included the 541st Combat Sustainment Support Battalion, 101st Military Intelligence Battalion and the 97th Military Police Battalion. The planned 1st Sustainment Brigade was intended to provide a full spectrum support including: configuring for, distributions and retrogrades to and from maneuver Brigade Combat Teams, other support brigades, and to joint interagency and multinational elements as directed. The DISCOM would support Early Entry Operations or Hub operations with augmentation, providing postal, replacement, and casualty operations as well as essential personnel services and Trial Defense Services on an area basis.

On 15 February 2007 the 1st Infantry Division Support Command (DISCOM) was redesignated as the 1st Sustainment Brigade. At the time of the redesignation it had only one subordinate battalion, the 1st Sustainment Brigade Special Troops Battalion. Subsequently, the 1st Infantry Division Headquarters and Headquarters Battalion, 541st Combat Sustainment Support Battalion and the 84th Ordnance Battalion (Explosive Ordnance Disposal) were assigned to the Brigade.
