Officially Licensed USMC 9th Engineer Support Battalion 3rd MLG Patch — 9th Engineer Support Bn, 3rd Marine Logistics Group Embroidered Patch
Building the way forward for Marines in the Pacific.
The 9th Engineer Support Battalion is a combat engineer unit assigned to the 3rd Marine Logistics Group (3rd MLG) and III Marine Expeditionary Force, based on Okinawa, Japan. The battalion provides general engineering support, construction, and combat engineering capabilities to Marine forces operating throughout the Indo-Pacific region. From building bridges and airfields to breaching obstacles and clearing routes, the 9th ESB's Marines are the ones who make the impossible terrain passable.
As part of the 3rd MLG, the 9th Engineer Support Battalion provides the heavy engineering muscle that enables Marine forces to operate in the Pacific's challenging and austere environments. Their capabilities include horizontal and vertical construction, bulk fuel operations, bridge building, explosive ordnance disposal support, and utility infrastructure installation. During exercises and real-world operations across the Pacific, the battalion's Marines construct forward operating bases, repair damaged infrastructure, and provide the engineering solutions that keep the logistics chain flowing. Their forward-deployed position in Okinawa ensures rapid response capability across the entire Indo-Pacific theater.
The 9th ESB's engineers are the quiet professionals who build the foundation upon which Marine operations succeed.
Perfect For: 9th Engineer Support Battalion veterans, 3rd MLG personnel, Marine combat engineers, Okinawa-based Marines, and USMC engineering unit collectors.
Engineers lead the way — 9th ESB.
