On 8 April 2008, the 2nd Brigade Combat Team, 2nd Infantry Division was inactivated and its personnel reflagged as the 4th Brigade Combat Team, 4th Infantry Division. Subsequently, the 2nd Brigade Support Battalion was subsequently inactivated and its personnel reflagged as the 704th Brigade Support Battalion.

The 2nd Brigade Support Battalion traced its history through several organizational changes to the 2nd Supply Train. It was first organized at Fort Sam Houston, Texas, on 1 October 1917. As a unit of the 2nd Quartermaster Battalion in 1939, the unit was again redesignated the 2nd Quartermaster Company on 21 October 1942.

In November 1942, the 2nd Quartermaster Company moved with the 2nd Infantry Division to Camp McCoy, Wisconsin, where it engaged in winter training followed by winter maneuvers in Michigan. In October 1943, after months of pre-combat training, the Company sailed for Northern Ireland where training continued in preparation for the invasion of Europe.

Crossing the English Channel as a unit of the 2nd Infantry Division, the 2nd Quartermaster Company landed in Normandy on 10 June 1944. Fighting across France, Belgium and Germany, the Company entered Filsan, Czechoslovakia. Eleven months and 5 campaigns later with battle credit for the campaigns of Normandy, Northern France, Ardennes, the Rhineland and Central Europe. It was cited twice in the Division orders for the Meritorious Service Award, and received the Belgium Fourragers.

After Occupation duty in Germany, the 2nd Quartermaster Company was reassigned to Korea. Campaigns included the UN Defensive and UN Offensive CFF Intervention, First UN Counter-Offensive, CFF Spring Offensive, UN Summer-Fall Offensive Second Korean Winter, Korean Summer-Fall 1952, Third Korean Winter and Korean Summer 1953. The unit was also awarded the Distinguished Unit Citation and 2 ROK Presidential Unit Citations.

In 1954, the 2nd Quartermaster Company returned to Fort Lewis, moving to Alaska in 1956. While in Alaska, the 2nd Quartermaster Company was transferred to Department of the Army control in 1957.

Less than a year later, the 2nd Quartermaster Company was reactivated to support to 2nd Infantry Division in its new role as a training division at Fort Benning, Georgia. After supporting training operation for almost 4 years the unit was readied for combat, and again began a new role as a member of the nation's STRAC force.

In March 1963, the 2nd Quartermaster Company was reorganized under the new ROAD concept and redesignated as the 2nd Supply and Transport Battalion. The unit remained on STRAC duty until 1 July 1965, when it returned to Korea in redesignation of the 15th Supply and Transport Battalion.

The 2nd Supply and Transport Battalion was reorganized under the Army of Excellence (AOE) and redesignated the 2nd Support Battalion (Forward) with organic elements constituted and activated on 16 October 1989. Organized as a Heavy Forward Support Battalion, the Battalion was placed in direct support of the 2nd Brigade, 2nd Infantry Division.

In August 2004, the 2nd Forward Support Battalion deployed from the Republic of Korea to Kuwait and, subsequently, into combat in the Al Anbar Province of Iraq. The Mustang Battalion served with distinction in the cities of Habbaniyah, Ar Ramadi, and Al Taqaddum before redeploying to its new home station in August 2005 at Fort Carson, Colorado.

After redeploying to Fort Carson, the 2nd Brigade began transformation under the US Army's new modular force structure. As a result, support elements previously held at division level and attached only during operations were made organic to new modular brigade combat teams. The 2nd Forward Support Battalion was redesignated as the 2nd Brigade Forward Support Battalion and reassigned from the 2nd Infantry Division Support Command (DISCOM) to the newly reorganized 2nd Brigade Combat Team, 2nd Infantry Division. The 2nd Infantry Division's DISCOM was inactivated.

As part of a larger reorganization of US Army forces at home and abroad, the 2nd Brigade Combat Team, 2nd Infantry Division was inactivated in April 2008 and reflagged as the 4th Brigade Combat Team, 4th Infantry Division. The 2nd Brigade Support Battalion was subsequently inactivated and its personnel reflagged as the 704th Brigade Support Battalion.
