In 2005, the Division Support Command (DISCOM), 25th Infantry Division was inactivated as part of the transformation of the 25th Infantry Division to the US Army's modular force structure.

The Division Support Command (DISCOM), 25th Infantry Division (Light), "Lightning Support," had the mission of providing logistics and medical support "forward to the foxhole," to the 25th Infantry Division (Light). The DISCOM conducted theater-wide deployment within 54 hours of notification to perform combat service support and combat health support, in support of the Division's combat mission and other missions as directed by the Commander in Chief.

The DISCOM was organized with four battalions and 2 separate companies: 25th Forward Support Battalion (supporting the 1st Brigade at Fort Lewis, Washington), 225th Forward Support Battalion (supporting the 2nd Brigade), 325th Forward Support Battalion (supporting the 3rd Brigade), the 725th Main Support Battalion (supporting the Division troops and reinforcing the Forward Support Battalions), Headquarters and Headquarters Company, and the 71st Chemical Company. In addition, the DISCOM managed the Division Materiel Management Office and the Medical Operation Center.

The Division Support Command (DISCOM), 25th Infantry Division (Light) was first constituted on 16 January 1957 and activated in the territory of Hawaii as the 25th Infantry Division Trains with 3 functional combat service support (CSS) battalions. On 1 July 1963, the Division Trains and the 25th Infantry Division Band were reorganized and redesignated as the DISCOM, 25th Infantry Division.

The DISCOM deployed to the Republic of Vietnam in 1966 and supported combat operations for the Tropic Lightning Division in country and in Cambodia. In 1970 it redeployed with the Division to Schofield Barracks, Hawaii. While in Vietnam, the DISCOM earned 12 campaign streamers and 5 unit citations.

On 5 February 1972, the DISCOM was reorganized with the 25th Infantry Division Band becoming a separate unit. In December 1982, the DISCOM provisionally reorganized into a multifunctional CSS organization with 2 forward support battalions and one main support battalion. Then in May 1985, the DISCOM returned to the 3 functional CSS battalion organization. Finally in May 1991, the DISCOM once again was reorganized into a multifunctional CSS organization with 3 FSBs, a MSB, an aviation intermediate maintenance company, and an attached corps chemical smoke/decontamination company. With the activation of the Aviation Brigade, 25th Infantry Division, the AVIM Company was reassigned to that formation from the DISCOM.

In 2005, the Division Support Command (DISCOM), 25th Infantry Division was inactivated as part of the transformation of the 25th Infantry Division to the US Army's modular force structure. Following the inactivation, the DISCOM elements were to be consolidated and restructured within other combat brigades. As part of the modular transformation, assets previously held at division level, but habitually assigned to the Division's brigades during operations were made organic to those brigades. 225th, 325th, and 725th Forward Support Battalions were all inactivated, reorganized, redesignated as Brigade Support Battalions and reactivated as the organic field artillery battalions for the reorganized and redesignated 1st, 2nd, and 3rd Brigade Combat Teams, 25th Infantry Division respectively. The 725th Main Support Battalion was inactivated and eventually reorganized, redesignated, and reactivated as the 725th Brigade Support Battalion, the organic support battalion for the 4th Brigade Combat Team, 25th Infantry Division.
