Combat Logistics Battalion

Combat Logistics Battalion (CLB) units are essential elements of the United States Marine Corps’ logistics support structure. Established in the early 2000s during the reorganization of Marine logistics groups, CLBs were designed to provide direct support to Marine regimental and battalion-sized units, especially during overseas contingency operations. CLBs have played critical roles in the wars in Iraq and Afghanistan, ensuring the timely delivery of supplies, maintenance, transportation, and health services across challenging and hostile environments. Their adaptability and forward-deployed support have made CLBs indispensable in modern Marine Corps expeditionary operations.
