U.S. Marine Corps Forces, Pacific (MARFORPAC)

Last Revised: March 10, 2015, 3:16 pm
Overview: 

MARFORPAC has three command roles and responsibilities. The command serves as the U.S. Marine Corps component to PACOM, USFK, and Fleet Marine Forces Commander to Pacific Fleet. An additional task for MARFORPAC may be to act as a JTF CE in addition to its service component responsibilities.

MARFORPAC’s headquarters are located aboard Camp H. M. Smith, HI, and is the largest field command in our Corps, having control of two-thirds of our operational forces (OPFOR). COMMARFORPAC commands and controls all of our forces assigned to USPACOM — approximately 86,000 Marines, Sailors and civilians — operating in a diverse geographic area stretching from Yuma, AZ to Goa, India.

COMMARFORPAC supports national and theater strategic objectives, and exercises our Corps’ component responsibilities in support of operational and concept plans, theater SC, foreign humanitarian assistance, homeland defense, force posture, and lay down. These responsibilities include a planned rotational presence in Northwestern Australia, and protection of installations and forces in the USPACOM AOR.

MARFORPAC conducts more than 160 major multi-lateral and bilateral exercises and theater SC engagements with some 30 allies and partners in the Asia-Pacific region annually. MARFORPAC forces also rapidly respond to a yearly average of 14 HA/DR operations.

MARFORPAC exercises coordinating authority in a consultative relationship with (Marine Corps Installations Command (MCICOM) through unity of effort for operational force base support requirements, Defense Policy Review Initiative (DPRI) requirements in Japan and Guam, USPACOM Unified Campaign Plan (UCP) and contingency planning requirements, and other installation support initiatives affecting our Corps in the PACOM AOR.

While MCICOM exercises command and administrative control over all of our bases and stations, two of MCICOM’s regional commands, MCIWEST and MCIPAC, have USPACOM-assigned forces as tenants. As such, COMMARFORPAC exercises TACON of Marine Corps Installations Pacific (MCIPAC) and Marine Corps Installations West (MCIWEST), or both, when supporting USPACOM tasking and operational missions.

COMMARFORPAC, in consultation and accord with Commander, Marine Corps Installations Command (COMMCICOM), may assume OPCON of MCIPAC, MCIWEST, and their assigned installations during exceptional circumstances that require a response from the United States in the PACOM AOR, such as HA/DR, or major combat operations.

  • About Concepts and Programs

    The vision of the Concepts and Programs project is to provide political and military leaders with timely, accurate, and relevant information. The Concepts and Programs project is the premier strategic communications vessel the Marine Corps relies on to inform Congress, the Office of Secretary of Defense, Chairman of the Joint Chiefs of Staff, and Think Tanks about the Corps’ vision.
