The 8th Theater Sustainment Command (8th TSC), as the senior Army logistics command in the United States Pacific Command's Area of Responsibility (AOR), provides command and control of all assigned and attached and units under its operational control (OPCON); trains, equips and tailors forces, as required; plans and generates expeditionary combat support/combat service support (CS/CSS) capability; and provides timely and robust support of joint and combined forces across the full spectrum of military operations in order to maintain peace and stability, deter aggression, and fight and win in the Pacific AOR.

The former 45th Corps Support Group was inactivated on 11 January 2006 and reorganized as the 8th Theater Sustainment Command (Provisional).

The regiment has WWII campaign credits for Normandy, Northern France, Rhineland, Ardennes-Alsace, Central Europe and the Asian-Pacific theatre.

From December 1995 to January 1996 all units in the brigade, except the 320th Engineer Company (Topographic), deployed to Croatia or Bosnia and Herzegovina in support of Operation Joint Endeavor.

In December 1995, the 502nd Engineer Company deployed to Zupanja, Croatia and placed the historic ribbon bridge over the Sava River.

Leaders recognized that if there were ever again a war in Korea, it would be necessary for all military police units to be put together in order to perform their wartime mission.

Again, on 1 October 1978, the command was reorganized as U.S. Army Support Activity, and its administration headquarters were further centralized at Camp Kinser.
