"Heart of the Rock"
The 3rd Sustainment Brigade is responsible for all logistics support to the 3rd Infantry Division (Mechanized). The 3rd Sustainment Brigade provides supply, maintenance, medical and transportation support to the maneuver brigades of the 3rd Infantry Division. Together, all of the units of the 3rd Sustainment Brigade serve as the logistical core that enables our Dogface Soldiers to dominate the battlefield.
The mission of the previous Division Support Command (DISCOM), was to deploy rapidly to contingency area by air, sea, and land perform Combat Service Support in a contingency area of operations and sustain mobile armored combined arms warfare.
The unit was constituted on 1 July 1957 in the regular army as Headquarters and Headquarters Detachment, 3rd Infantry Division Trains, and activated at Fort Benning, Georgia.
On 20 March 1963, the unit was consolidated with the 3rd Infantry Division Band, (first organized in 1943 as the Band, 3rd Infantry Division). The consolidated unit was reorganized and redesignated as Headquarters, Headquarters and Band, 3rd Infantry Division Support Command.
On 15 March 1968, the unit was reorganized and redesigned as Headquarters and Headquarters Company and Band, 3rd Infantry Division Support Command.
The unit was again reorganized and redesignated on 21 May 1972 as Headquarters and Headquarters Company, 3rd Infantry Division Support Command. The Band was concurrently withdrawn and thereafter had a separate lineage.
In the fall of 2002, the Division Support Command deployed in support of Operation Iraqi Freedom I, earning the Presidential Unit Citation.
As part of the transformation of the 3rd Infantry Division (Mechanized) to the US Army's new modular force structure, the Division Support Command was redesignated the Division Support Brigade and deployed to Iraq in the fall of 2004 in support of OIF III. This unit began to reorganize to reflect the various changes in relationship between support units at Corps, Division, and Brigade level under the modular force structure. As a result the Brigade's 3 Forward Support Battalions and Main Support Battalion were inactivated. These units were redesignated and reorganized as Brigade Support Battalions, and subsequently reactivated as organic elements of the Division's 4 modular Brigades. Elements of the 3rd Infantry Division's Engineer Brigade and the 24th Corps Support Group (both inactivated as part of the modular transformation) were also integrated into the new unit. The 92nd Chemical Company became part of the Division Support Brigade Troops Battalion. The 87th Corps Support Battalion was also inactivated, reorganized, and redesignated as the 87th Combat Sustainment Support Battalion, and assigned to the Division Support Brigade. The Brigade also gained the 92nd Engineer Battalion and 260th Quartermaster Battalion.
The Division Support Brigade was reorganized as the 3rd Support Brigade on 15 June 2005. The lineage and honors of the unit previously known as the 3rd Support Brigade, which had functioned as a training support brigade before being inactivated as part of the Training Support XXI program in 1999, were consolidated with that of the Division Support Brigade, 3rd Infantry Division. The 3rd Support Brigade had previously been active in the Army reserve from 30 October 1997 to 14 September 1999, before being reflagged as 3rd Brigade, 78th Division (Training Support). The 3rd Support Brigade was again redesignated as the 3rd Sustainment Brigade on 21 April 2006. The Troops Battalion became the Special Troops Battalion, 3rd Sustainment Brigade.
In July 2007 the 3rd Sustainment Brigade conducted a relief in place of the 45th Sustainment Brigade, 13th Sustainment Command (Expeditionary) at Forward Operating Base Q-West in Iraq. The mission was to provide combat service support to Multinational Division, North, which included more than a dozen forward operating bases. This was the third deployment for the 3rd Sustainment Brigade, which previously deployed in support of Operation Iraqi Freedom I as the 3rd Division Support Command and in OIF III as the 3rd Division Support Brigade. The unit earned the Presidential Unit Citation for their support of the first operation.
In August 2008 the 16th Sustainment Brigade, 3rd Sustainment Command relieved the 3rd Sustainment Brigade, which returned to Fort Stewart, Georgia.
