Force Design 2030 update accelerates agile, distributed sustainment as III MEF expands logistics capacity amid rising regional threats
CAMP SCHWAB, Japan | The U.S. Marine Corps has activated three new combat logistics companies in Japan, marking a significant step in the service’s intensified push toward agile, distributed sustainment across the Indo-Pacific under Force Design 2030.
Combat Logistics Battalion 4 (CLB-4) formally stood up its Headquarters, Alpha, and General Service Companies during a Nov. 14 activation ceremony at Camp Schwab, the Marine Corps confirmed. A fourth unit—Bravo Company—is expected to follow as part of the battalion’s expanding footprint in the region.
The new formations underscore the service’s sharpened focus on expeditionary logistics, an area Commandant Gen. Eric Smith has repeatedly described as essential for surviving and prevailing across contested island chains stretching from Japan to the Philippines.
A Logistics Shift Driven by a Changing Battlespace
CLB-4 commanding officer Lt. Col. Nathan Green said the activation represents a generational shift in how the Marine Corps equips, sustains, and moves forces across the Indo-Pacific’s vast distances.
“This is about outpacing our adversaries in a rapidly evolving operating environment,” Green said. “The theater demands flexibility. If we have to change again, we’ll change again.”
Smith echoed that urgency in the October update to Force Design 2030, emphasizing that logistics agility is no longer optional—it's foundational.
“We are modernizing at a time when the character of war is shifting rapidly,” Smith wrote. “Drones, long-range precision fires, cyber effects and electronic warfare are now daily features of conflict. Victory belongs to the side that adapts faster, fights harder and endures longer.”
Strategic Adjustments in III Marine Expeditionary Force
The logistical overhaul comes as the Marine Corps reconsiders earlier assumptions about force structure in the region. Under the original Force Design blueprint, the 4th Marine Regiment—currently aligned with III MEF in Japan—was slated to convert into a Marine Littoral Regiment (MLR) based in Guam.
However, the October update reversed course, preserving the 4th Marines as a reinforced infantry regiment within III MEF. Marine Corps spokesperson Lt. Col. Eric Flanagan said the shift reflects evolving threat models and outcomes from recent wargames.
“This decision is informed by updated wargames and analysis addressing the growing threat posed by competitors in the Indo-Pacific,” Flanagan said. “Retaining the 4th Marines ensures we maintain the ability to decisively respond to regional threats, deter aggression, and support allies and partners.”
Building Toward a Distributed, Survivable Future Force
CLB-4’s activation marks another step in the Corps' broader effort to reshape sustainment for stand-in forces expected to operate inside contested zones. The battalion’s Japan-based presence will support rapid equipping of the 4th Marine Regiment and forward-deployed naval expeditionary elements.
Marine officials say upcoming joint exercises across Japan and the First Island Chain will refine how the new logistics companies integrate with stand-in forces, Littoral Combat Teams, Expeditionary Advanced Bases (EABs), and U.S. Navy partners.
As adversaries expand long-range strike, electronic warfare, and unmanned capabilities, the Marine Corps is betting that leaner, more mobile logistics units will be essential to ensuring III MEF can sustain distributed operations—especially in the opening stages of a crisis.
