At Kobe, Japan, the Support Company of 1st CSG processed Marine drafts arriving and departing Korea. At Masan, the Supply Company of 1st CSG requisitioned for the division those Class II and IV items peculiar to the Marine Corps needs and forwarded them upon request. Heavy maintenance of all technical equipment was performed by the Maintenance Company of 1st CSG. Supporting the 1st Motor Transport Battalion operations was the Motor Transport Company of 1st CSG. Most of the CSG, including Headquarters Company, was based at Masan. Splinter detachments from the Group also operated transport facilities at other locations in Korea.

1980s

During September 1986, a milestone was reached in the long-term effort to improve the organization of the Corps' FSSGs, with phase I of the reorganization underway. Earlier that year, the decision was made to pursue the general reorganization concept contained in the Center for Naval Analyses, Combat Service Support Structure Study of 1985 to restructure the FSSG's functional battalions in a way that would facilitate deployment of Marine amphibious brigades and simplify task organizing for other MAGTF commitments. A trial for the revised structures was scheduled to begin during early 1987.

from September 1990 to April 1991. Brigadier General James A. Brabham Jr., a native Pennsylvanian who served twice in Vietnam and as the Deputy J-4 for logistics at USCENTCOM, commanded I MEF's combat service support element – the 1st FSSG. General Brabham reorganized 1st FSSG into a direct support group, a general support group, and a headquarters and services group. General Brabham assigned Colonel Alexander Powell, the former commander of BSSG-7, as the commander of Direct Support Group (DSG) 1 and gave him the responsibility of sustaining the 1st Marine Division and the 3d Marine Aircraft Wing. Expecting to be the 1st FSSG's operations officer upon arrival, Colonel Thomas E. Hampton, a former infantry officer and Vietnam war veteran from southern Illinois, was instead ordered by General Brabham to take charge of General Support Group (GSG). The mission of the GSG organization was to provide general support to the MEF. To command the Headquarters and Support Group (H&SG), General Brabham tapped Lieutenant Colonel Henry T. Hayden and ordered him to provide internal support to the 1st FSSG, a variety of services to I MEF, and to coordinate port security. Following Operation Desert Storm, the 1st FSSG, under the command of BGen Ted Hopgood (a career infantryman), participated in
