498th Combat Sustainment Support Battalion
498th Corps Support Battalion (Provisional)
Following the reorganization and redesignation of the 501st Corps Support Group as the 501st Sustainment Brigade, the 498th Corps Support Battalion was similarly reorganized and redesiganted as the 498th Combat Sustainment Support Battalion.
Prior to its reorganization, the 498th Corps Support Battalion, headquartered in Seoul, a subordinate command of the 501st Corps Support Group, consisted of a headquarters and headquarters Company, 2 maintenance companies, 2 supply companies and one medium truck company. Its missions included supply operation and accountability, direct support maintenance and medium truck transportation.
The 498th Corps Support Battalion's mission was to provide command and control, administrative, training and life support for Headquarters and Headquarters Detachment, 498th Corps Support Battalion. It also included providing combat service support to non-divisional forward deployed units in the combat zone of korea and backup direct support combat service support to the 2nd infantry division. Additionally, it would provide line haul transportation support to the entire theater and, on order, conduct noncombatant evacuation operations.
The colors and lineage of the 227th Maintenance Battalion were returned to the United States on 15 September 1999. At that time, the unit was reflagged as the 498th Corps Support Battalion (Provisional). Since 1971, a battalion had served continuously in the Republic of Korea, fulfilling an important part in supporting the Area II community. The reflagging aligned the unit's command and control structure to the subordinate units it managed.
In December 2005, the 19th Theater Support Command was reorganized and redesiganted as the 19th Expeditionary Support Command. As part of this reorganization, the 501st Corps Support Group was also reorganized and redesignated as the 501st Sustainment Brigade. The 3 Area Support Commands were inactivated. The 498th Corps Support Battalion remained assigned to the new 501st Sustainment Brigade, but was reorganized and redesignated as the 498th Combat Sustainment Support Battalion reflecting the various reorganizations in roles and missions of support units in Korea. This was a product of both the transformation of the US Army to the new modular force structure and the drawdown of US forces in Korea.
