31st MEU Embarks with the America Amphibious Ready Group

The Amphibious Ready Group-Marine Expeditionary Unit (ARG/MEU) forms a cohesive Navy and Marine Corps combined-arms team, ready to respond across a range of military operations. The Navy and Marine Corps team delivers decisive, integrated American naval power.

The America ARG is based out of Sasebo, Japan, and is comprised of the staff of Amphibious Squadron (PHIBRON) 11 and its three ships: the amphibious assault carrier USS America (LHA 6), the amphibious transport dock ship USS San Diego (LPD 22), and the amphibious dock landing ship USS Rushmore (LSD 47). The 31st MEU, headquartered out of Camp Hansen, Okinawa, Japan, consists of a command element, an aviation combat element with F-35B Lightning II aircraft, a combat logistics battalion and a ground combat element.

“We’re looking at a pretty large chunk of INDOPACOM’s ‘ready now’ combat power,” said U.S. Marine Corps Col. Chris Niedziocha, the commanding officer of the 31st Marine Expeditionary Unit. “Here in the first island chain, the ARG/MEU team competes every day with our opponent. It’s exhilarating to be this far forward, embarked aboard warships – deterring the adversary, reassuring our partners, and signaling resolve.”

The ARG/MEU, which consists of more than 5,000 Marines and Sailors, is underway conducting routine operations in U.S. 7th Fleet area of operations. U.S. 7th Fleet is the U.S. Navy’s largest forward-deployed number fleet and routinely interacts and operates with allies and partners to preserve a free and open Indo-Pacific region.
