34th MAU FMF
U.S. Marine Corps
The 34th Marine Amphibious Unit (MAU), Fleet Marine Force (FMF), was a provisional, battalion-sized unit of the United States Marine Corps, activated for specific operational deployments during the late 1970s and early 1980s. The 34th MAU provided a forward-deployed, rapid-response force capable of conducting amphibious operations, crisis response, and contingency missions, primarily in the Mediterranean and Middle East regions. Notably, the 34th MAU participated in operations such as the multinational peacekeeping mission in Lebanon during the early 1980s. In 1988, the Marine Corps redesignated its MAUs as Marine Expeditionary Units (MEUs), and the 34th MAU evolved into the 24th MEU, continuing its legacy of expeditionary readiness.
5th 155 Gun Battery
U.S. Marine Corps
The 5th 155 Gun Battery was a field artillery unit equipped with 155mm towed guns, traditionally providing long-range fire support for infantry and armored formations. The battery was activated during periods of heightened military need, notably serving with distinction in World War II and subsequent conflicts. Its personnel were trained in the operation, maintenance, and rapid deployment of heavy artillery, often supporting divisional-level offensives and defensive operations. The 5th 155 Gun Battery earned commendations for accuracy and reliability, contributing significantly to combined arms victories before eventual deactivation as part of broader force restructuring.
5th MAB
U.S. Marine Corps
The 5th Marine Amphibious Brigade (5th MAB) was a United States Marine Corps unit activated during periods of heightened military readiness. Initially formed during the Vietnam War era, the brigade was designed to provide a rapid-response amphibious force capable of deploying in crisis zones. Notably, the 5th MAB was reactivated during the late 1970s and played a key role in the planning for Operation Eagle Claw, the attempted rescue of American hostages in Iran in 1980. Although the mission was ultimately unsuccessful, the unit’s preparation and involvement underscored its strategic importance in U.S. military contingency operations.
6th Mab
U.S. Marine Corps
The 6th Marine Amphibious Brigade (6th MAB) was a task-organized unit of the United States Marine Corps, formed to provide rapid, flexible amphibious capabilities for contingency operations. Activated during times of crisis, such as the Lebanon intervention in 1982-1984, the 6th MAB comprised infantry, aviation, and support elements, enabling it to conduct a wide range of missions from peacekeeping to combat operations. The brigade played a key role in the multinational peacekeeping force in Beirut, demonstrating the Marines’ expeditionary and amphibious warfare expertise. After completing its missions, the 6th MAB was typically deactivated, with its components reassigned to other Marine Corps units.
7TH FSSG 24TH MARINES RESERVE
U.S. Marine Corps
The 7th Force Service Support Group (FSSG), in conjunction with the 24th Marines (Reserve), played a vital role in providing logistical and combat support to Marine Corps Reserve operations. Established to ensure that reserve infantry units like the 24th Marines maintained high readiness, the 7th FSSG delivered essential services such as supply, transportation, health services, and maintenance. Throughout its history, the 7th FSSG supported major training exercises and mobilizations, including deployments in support of Operations Desert Storm and Iraqi Freedom. The partnership between 7th FSSG and the 24th Marines exemplified the integration of combat and support elements within the Marine Corps Reserve, enhancing the Corps’ ability to rapidly project power worldwide.
