History

The brigade was stationed at Kaneohe Bay Marine Corps Air Station (MCAS) from 1956 (when the 1st Provisional Marine Air Ground Task Force was redesignated as the 1st Marine Brigade), until 30 September 1994, when the brigade was deactivated. In 1960 and again in 1964, the brigade participated in large-scale exercises in Taiwan; and in 1990 the 1st Marine Expeditionary Brigade deployed to Southwest Asia during Operation Desert Shield.

From 1956 to 1985 while at Kaneohe MCAS, (now known as Marine Corps Base Hawaii), the unit was designated as the 1st Marine Brigade. From 1985 until 1988, the brigade was designated as the 1st Marine Amphibious Brigade^[2] and was then redesignated as the 1st Marine Expeditionary Brigade.^[3] From 1971, in addition to the Brigade Headquarters Group as its Command Element (CE), the 1st Marine Brigade consisted of the 3rd Marine Regiment (from 1956 until 1965 the 4th Marine Regiment filled this role in the brigade) as its Ground Combat Element (GCE), Marine Aircraft Group 24 (MAG-24) as its Aviation Combat Element (ACE), and a Brigade Service Support Group (BSSG) as it Logistics Combat Element (LCE).
