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.
