The 4th Force Service Support Group (4th FSSG) was a unit of the United States Marine Corps Reserve, established to provide combat service support to Marine Forces Reserve units. Activated in 1962, 4th FSSG was headquartered in New Orleans, Louisiana, and comprised various subordinate units specializing in logistics, supply, maintenance, medical, and transportation. Throughout its history, the 4th FSSG played a vital role in supporting both training exercises and operational deployments, including mobilizations for Operations Desert Shield/Desert Storm and Operation Iraqi Freedom. In 2006, the unit was reorganized and redesignated as the 4th Marine Logistics Group (4th MLG), continuing its legacy of logistical excellence within the Marine Corps Reserve.
