OKINAWA, Japan - U.S. Marines with Marine Medium Tiltrotor Squadron (VMM) 265 (Rein.) and Battalion Landing Team 1st Battalion, 7th Marine Regiment, 31st Marine Expeditionary Unit, executed a long-range helicopter insert exercise to Combined Arms Training Center Camp Fuji, Japan, Sep. 23, 2025, where they conducted combined arms live-fire training to maintain operational readiness, tactical proficiency, and enhance lethality while operating within the Indo-Pacific. In less than 36-hours, two waves encompassing nearly 400 Marines assigned to BLT 1/7, were transported non-stop over 1,000 miles with eight MV-22Bs and four CH-53Es to CATC Camp Fuji, Japan from Marine Corps Air Station Futenma, Okinawa, Japan. The movement demonstrated the MEU’s ability to rapidly deploy a BLT from Okinawa to a forward deployed location utilizing only military aircraft, according to Maj. James Hurton, the operations officer for BLT 1/7. “This movement allowed the BLT to mass credible combat power at a location of our choosing along a very short timeline,” said Hurton. “This capability can be used to preposition forces within the Indo-Pacific Command area of responsibility should the need arise.” Marine Medium Tiltrotor Squadron (VMM) 265 (Rein.), the Marine Air Element attached to the 31st MEU, supported the movement by providing long-range logistical capabilities via MV-22B Ospreys and CH-53E Super Stallions.

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.
