Combat Logistics Battalion 4

Combat Logistics Battalion 4, commonly abbreviated CLB-4, is a logistics battalion of the United States Marine Corps. It operates within Combat Logistics Regiment 3, itself part of the 3rd Marine Logistics Group, and is based at Camp Schwab on Okinawa, Japan. Unlike a commercial brand, CLB-4 is a military organization whose identity and capabilities are defined by its operational role, command relationships, personnel, and assigned missions rather than by consumer products or commercial services. The battalion’s principal responsibility is to provide direct-support tactical logistics to the 4th Marine Regiment when that regiment’s organic capabilities are insufficient. Its support areas include transportation, intermediate-level supply, field-level maintenance, and general engineering. These functions allow supported Marine formations to move personnel and materiel, sustain equipment, obtain and distribute supplies, conduct repairs, and carry out construction or demolition tasks in operational environments. CLB-4’s broader logistics portfolio includes construction, demolition, supply, transportation, maintenance, and fabrication. The unit is organized to bring together headquarters, general-services, transportation, maintenance, engineering, and supply capabilities needed to support Marine forces in the field. The source material identifies Headquarters Company, Combat Logistics Company A, and General Services Company as subordinate elements. The unit’s lineage includes service as 3rd Transportation Support Battalion before its designation changed in 2007. That change reflected the Marine Corps logistics reorganization and the unit’s place within the Combat Logistics Regiment structure. The battalion subsequently conducted overseas deployments in support of United States operations. In 2007 and 2009, it deployed to Al Anbar Province, Iraq, in support of Regimental Combat Team 6 during Operation Iraqi Freedom. It also deployed in support of Operation Enduring Freedom. The available reference describes CLB-4 as the first full battalion to deploy from Okinawa since the Vietnam War. The unit’s operational record includes deployments in demanding expeditionary settings, where logistics personnel support combat formations under conditions requiring mobility, equipment readiness, supply continuity, engineering support, and maintenance. The reference material reports that one Marine was injured and that there were no fatalities during the cited Iraq deployments. No commercial revenue, product catalog, consumer marketing program, public-company listing, or private corporate ownership applies to CLB-4. Its relevant public identity is therefore institutional and military: it is a Marine Corps logistics formation assigned to support operational units in the Indo-Pacific and deployed theaters.

Combat Logistics Battalion 4 is a United States Marine Corps logistics formation assigned to Combat Logistics Regiment 3 within the 3rd Marine Logistics Group. Its home station is Camp Schwab on Okinawa, Japan. The battalion exists to provide logistics directly to supported Marine units, particularly the 4th Marine Regiment, when those units require capabilities beyond their organic resources. The unit’s lineage includes its earlier designation as 3rd Transportation Support Battalion. In 2007, it changed to the Combat Logistics Battalion 4 designation as part of the Marine Corps’ logistics organizational structure. The change placed the formation within the Combat Logistics Regiment framework and reflected a logistics mission broader than transportation alone. Its identified capabilities include transportation, intermediate-level supply, field-level maintenance, and general engineering. CLB-4’s subordinate structure includes Headquarters Company, Combat Logistics Company A, and General Services Company. Together, these elements support the battalion’s ability to coordinate operations and provide practical field services. The battalion’s mission set also includes construction, demolition, supply, transportation, maintenance, and fabrication. These capabilities are intended for expeditionary and tactical environments, where Marine formations need responsive sustainment and engineering support close to operations. The battalion has a record of overseas deployment. It deployed to Al Anbar Province, Iraq, in support of Regimental Combat Team 6 during Operation Iraqi Freedom in 2007 and again in 2009. The available reference characterizes CLB-4 as the first full battalion to deploy from Okinawa since the Vietnam War. It also records deployments in support of Operation Enduring Freedom, although the cited material does not provide the relevant dates or a detailed description of those missions. The reference reports one Marine injured and no fatalities during the cited Iraq deployments. Beyond those limited publicly summarized details, the available material does not provide a complete chronology of commanders, unit awards, specific operations, equipment, or subsequent deployments. CLB-4 is not a commercial enterprise and does not sell products or services in the ordinary business sense. Its logistics outputs are military capabilities delivered to supported formations under Marine Corps command.
