Overview
Combat Logistics Battalion 46, commonly abbreviated CLB-46, is a logistics unit of the United States Marine Corps Reserve. It was activated on 1 June 2009 at Marine Corps Base Camp Lejeune, North Carolina, as a separate and detached command within the 4th Marine Logistics Group. Its creation was associated with the Marine Corps' need for a reserve logistics formation capable of directly supporting operations connected with the wars in Iraq and Afghanistan. The battalion is headquartered in Red Bank, New Jersey, and draws personnel from a geographically dispersed Marine Corps Reserve structure. At activation, its members came from 54 sites in 40 states and from across the nine battalions of the 4th Marine Logistics Group. This distributed composition reflects the reserve force's national recruiting and basing model rather than a conventional commercial or geographic operating footprint. CLB-46's mission is to provide general and direct support, together with sustained combat service support, when the requirements of a Marine Air-Ground Task Force exceed the capabilities of its organic support elements. Its functions are organized around logistics and field support rather than the manufacture or sale of products. The battalion's subordinate companies include Headquarters & Service Company, Engineer Support Company, Transportation Support Company, Health Service Company, Security Company, and Maintenance Company. Together, these elements support transportation, engineering, medical services, maintenance, security, and the movement and distribution of essential supplies. The unit's documented operational deployment was in support of Operation Iraqi Freedom during the Marine Corps drawdown of forces in Iraq. CLB-46 arrived in Iraq in late August 2009 and assumed logistics responsibilities in western Iraq from Combat Logistics Battalion 7. During the deployment it operated under Combat Logistics Regiment 25 of the 2nd Marine Logistics Group. Its work covered the Al Anbar Governorate, a large desert region west of Baghdad, where it supported forward operating bases and movement networks. Operational tasks included route-clearance patrols, as well as the delivery of food, water, ammunition, and fuel. These activities placed the battalion at the intersection of transportation, supply-chain management, engineering, security, and sustainment in a combat environment. The available reference material states that the battalion suffered no casualties during this deployment. Members began returning to the United States in January 2010. Combat Logistics Battalion 46 should therefore be understood as a military organization and operational support capability, not as a consumer brand or commercial logistics company. Publicly available reference material identifies its organizational role, activation, composition, subordinate units, and Iraq deployment, but does not establish a current commander, later deployments, a commercial website, or a current operational status.
History
Combat Logistics Battalion 46 was activated on 1 June 2009 at Marine Corps Base Camp Lejeune, North Carolina. It was established as a separate and detached command within the 4th Marine Logistics Group, a formation of the United States Marine Corps Reserve. The battalion's formation supported the Marine Corps requirement for additional logistics capacity during operations associated with Iraq and Afghanistan. Unlike a commercial logistics provider, CLB-46 exists to deliver military combat-service support. Its mission is to provide general and direct support and sustained logistics assistance when the support elements organic to a Marine Air-Ground Task Force cannot meet operational requirements on their own. The battalion's structure reflects this broad mission. It includes Headquarters & Service Company, Engineer Support Company, Transportation Support Company, Health Service Company, Security Company, and Maintenance Company. Personnel were assembled from 54 sites in 40 states across the nine battalions of the 4th Marine Logistics Group. This national distribution is characteristic of a Marine Corps Reserve unit and gave the battalion a dispersed personnel base before deployment. The battalion's documented deployment took place during Operation Iraqi Freedom. It arrived in Iraq in late August 2009 and assumed responsibility for logistics support in western Iraq from Combat Logistics Battalion 7. While deployed, CLB-46 fell under Combat Logistics Regiment 25 of the 2nd Marine Logistics Group. Its operational area included the Al Anbar Governorate, a large desert province west of Baghdad. The deployment involved sustaining forward operating bases and supporting movement across a demanding operational environment. Reported activities included route-clearance patrols and the delivery of food, water, ammunition, and fuel. These duties required the integration of transportation, supply, maintenance, security, engineering, and medical capabilities. The available reference material reports that the battalion suffered no casualties during the deployment. Personnel began returning to the United States in January 2010. The available material does not document a later deployment, a current commanding officer, a formal deactivation, or a subsequent organizational redesign. Accordingly, the unit's present status should be treated as requiring verification rather than assumed to be active or defunct.
