After Operation Desert Storm, AMC redesigned LAPA and created Logistics Support Elements (LSE).

In October 1994, AMC LSE-FE was established at Camp Market, Korea with the responsibilities of developing AMC Contingency Plans (CONPLANs), Mobilization Plans (MOBPLANs), and Operations Plans (OPLANs) in support of Army Service Component Commanders (ASCC) for contingency operations within PACOM; however, during this time, the management of the War Reserve Stocks (WRS), Depot Support Activity Far East (DSAFE) and other Logistics assets within PACOM were splintered under direct management of various AMC staff sections and organizations.

Effective 16 October 2008, the organization formally became, the 403d Army Field Support Brigade, with an approved MTOE and TDA.

On 1 October 2012, the Installation Management Command (IMCOM) Director of Logistics (DOL) resources and personnel in Korea and Japan transferred to the 403d AFSB with the mission of providing logistical support encompassing supply and services, transportation, and maintenance services to all regional and garrison forces including dependants.

The Brigade continues to provide tactical to strategic-level sustainment in order to ensure Theater readiness and enable Commanders to conduct Unified-Action and the full range of military operations in Northeast Asia.
