U.S. Marine Corps Forces Pacific is the largest operational command in the Marine Corps. It comprises two-thirds of the Marine Corps’ active-duty combat forces, I Marine Expeditionary Force and III Marine Expeditionary Force, collectively known as the “Pacific Marines.”
Pacific Marines serve as an expeditionary force-in-readiness. They operate as air-ground-logistics teams and are forward positioned and actively employed throughout the Indo-Pacific every day.
Pacific Marines live and work alongside the joint force and like-minded Allies and partners to prevent conflict, respond to crisis, and if the Nation calls, to fight and win.

Well before the sunlight kissed the slopes of Mount Fuji, U.S. Marines prepared to make history with a display of lethality. A highly anticipated High Mobility Artillery Rocket System (HIMARS) live-fire exercise at the Combined Arms Training Center marked a turning point in U.S. defense Oct. 27, two weeks before the Marine Corps’ Birthday.
Camp Hansen, Okinawa, Japan – In October 2025, for the first time since the USS Tripoli (LHA 7) sailed to the Indo-Pacific, the 31st Marine Expeditionary Unit (MEU) Command Element embarked the USS Tripoli, marking a pivotal shift in the unit’s operational posture and amphibious capabilities. This integration signals the beginning of a new chapter for the 31st MEU as it begins long-term operations with the Tripoli, marking the transition from USS America (LHA 6), which served as the MEU’s primary aviation platform in the Indo-Pacific for the past six years. The staff's arrival aboard Tripoli establishes the relationships needed to execute a forward, sea-based command and control node capable of directing complex expeditionary military operations across the Indo-Pacific. This integration allows the 31st MEU to have long-distance force projection from a mobile, self-sustained platform and rapidly respond to contingencies throughout the region.
