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.

During the Vietnam War, Marine forces conducted amphibious and helicopter-borne operations as part of Special Landing Force Alpha, including during Operation Swift, employing integrated air, ground, and logistics elements in combat that reinforced the MAGTF construct and helped shape the MEU’s role as a forward-deployed, rapid-response force.

The Marine Corps has long been committed to retaining its talented individuals. The E-8 Redesignation Pilot Program serves to continue that commitment to retaining and growing talent. By allowing master sergeants to shift into the first sergeant role, the program allows the Marine Corps to leverage the leadership capabilities of seasoned Marines, aligning talent more efficiently with the Corps’ operational needs. First Sergeant Christopher J. McCullar exemplifies talent that the Marine Corps seeks to keep. His outstanding performance over nearly two decades has afforded him the chance to chase after something he’s wanted since his early days in the Marine Corps.
