Overview
Combat Logistics Battalion 23, commonly abbreviated CLB-23, is a logistics unit of the United States Marine Corps Reserve. The battalion is associated with Marine Forces Reserve and operates within the command structure of the 4th Marine Logistics Group. Its headquarters is identified with Joint Base Lewis-McChord in Washington, while its distributed organization includes units located in Washington, Oregon, and California. The battalion's structure reflects the geographically dispersed character of the Marine Corps Reserve and enables it to assemble personnel and capabilities for expeditionary logistics missions. The battalion's core role is to extend the capabilities of a Regimental Combat Team and other Marine Air-Ground Task Force maneuver elements. Combat logistics battalions can be rapidly task-organized, deployed, employed, and redeployed to provide support beyond the organic logistics capacity of supported formations. Their work may include transportation, maintenance, engineering services, supply-related support, and the operation of forward logistics sites. CLB-23 is also expected to be prepared to assume the responsibilities of a Logistics Combat Element when directed. CLB-23 was created in 2013 through the redesignation of 4th Landing Support Battalion. The predecessor unit formally deactivated on 7 September 2013 at its headquarters on Joint Base Lewis-McChord, and CLB-23 uncased its colors during the same ceremony. Lieutenant Colonel David L. Brooks, USMCR, served as the battalion's first commanding officer. The reorganization aligned the reserve battalion with the organizational model used by active-duty Marine Corps combat logistics battalions. In 2015, the battalion completed an Integrated Training Exercise at Marine Corps Air Ground Combat Center Twentynine Palms in California. The exercise included an Infantry Training Exercise and an Enhanced Motor Operations Course completed by the third platoon of Transportation Services Company. The training supported the battalion's designation as fully operational and ready for combat operations. In 2018, CLB-23 participated in support of NATO's Saber Strike exercise in Latvia and Lithuania. Its personnel supported United States Army units and European partner forces in the Baltic region. Headquarters and Service Company personnel helped maintain forward operating base functions, while personnel from Transportation Services Company supported Norwegian infantry and Marines from 1st Battalion, 6th Marines. These activities illustrate the battalion's role as an enabler of multinational maneuver operations rather than as a consumer-facing commercial brand. There is no conventional product portfolio, revenue model, public share listing, or commercial website associated with the unit.
History
Combat Logistics Battalion 23 is a United States Marine Corps Reserve logistics battalion created in 2013 from the redesignation of 4th Landing Support Battalion. The transition marked a change from the predecessor unit's designation to the Marine Corps combat logistics battalion model used to support expeditionary maneuver forces. On 7 September 2013, 4th Landing Support Battalion held its deactivation ceremony at its Joint Base Lewis-McChord headquarters. During the same event, Combat Logistics Battalion 23 formally uncased its colors, establishing the unit under its new identity. Lieutenant Colonel David L. Brooks, USMCR, was the battalion's first commanding officer. The new battalion was organized to resemble active-duty Marine Corps combat logistics battalions while retaining the geographically distributed character of a reserve formation. Its reported organization includes Headquarters and Service Company at Joint Base Lewis-McChord, Engineer Services Company in Springfield, Oregon, Maintenance Services Company in Sacramento, California, and Transportation Services Company in Lathrop, California. This structure brings together command, engineering, maintenance, and transportation capabilities that can be combined according to the needs of a supported force. CLB-23's operational mission is to provide logistics combat support to a Regimental Combat Team and additional Marine Air-Ground Task Force maneuver elements operating in the supported unit's battlespace. The battalion is intended to supply capabilities beyond those available organically to maneuver units, helping maintain continuity of operations during deployment and combat. Its stated readiness requirement includes the ability to assume the duties of a Logistics Combat Element when directed. In practical terms, that mission can involve moving personnel and materiel, keeping vehicles and equipment operational, performing engineering tasks, and sustaining forward operating locations. Training in the first years after activation focused on integrating the battalion's dispersed companies and validating its ability to function in a combat environment. In June 2015, CLB-23 completed a battalion-wide Integrated Training Exercise at Marine Corps Air Ground Combat Center Twentynine Palms, California. The associated Infantry Training Exercise included an Enhanced Motor Operations Course completed by the third platoon of Transportation Services Company. The exercise produced a strong readiness result for that platoon and supported the battalion's designation as fully operational and prepared for combat operations. The battalion later participated in multinational readiness activity in northern Europe. In June 2018, CLB-23 supported NATO forces during Saber Strike in Latvia and Lithuania. Headquarters and Service Company personnel supported forward operating base functions, while the third platoon of Transportation Services Company provided logistical assistance to Norwegian infantry units and Marines from 1st Battalion, 6th Marines. The battalion also supported adjoining United States Army units and other European partner nations. This deployment demonstrated the reserve unit's ability to integrate with joint and multinational formations. CLB-23 is not a commercial company or consumer brand. It has no reported commercial product catalog, public financial statements, stock ticker, or conventional corporate ownership structure. Its identity is instead that of a military organization whose principal offering is mission capability: deployable logistics support for Marine and partner forces.
