United States Indo-Pacific Command (USINDOPACOM) is one of six geographic combatant commands defined by the Department of Defense's Unified Command Plan (UCP). As a geographic combatant command, USINDOPACOM is in charge of using and integrating United States Army, Navy, Air Force and Marine Corps forces within the USINDOPACOM area of responsibility (AOR) to achieve U.S. national security objectives while protecting national interests.

The commander of U.S. Indo-Pacific Command reports to the President of the United States through the Secretary of Defense and is supported by multiple component and sub-unified commands including: U.S. Forces Korea, US Forces Japan, U.S. Special Operations Command Pacific, U.S. Pacific Fleet, U.S. Marine Forces Pacific, U.S. Pacific Air Forces and U.S. Army Pacific. These commands are headquartered in Hawai’i and have forces stationed and deployed throughout the region.
