12th Marine Regiment redesignated to 12th Marine Littoral Regiment (MLR) on November 15, 2023, during a ceremony at Camp Hansen, Okinawa, Japan. This redesignation is the first step in the process outlined in January’s Security Consultative Committee (“2+2”) announcement that reinforces the enduring commitment of the U.S. to the defense of Japan and to peace and stability in the Indo-Pacific.

“Today marks a significant milestone in the storied history of the 12th Marine Regiment as they redesignate to the 12th Marine Littoral Regiment,” said Maj. Gen. Christian Wortman, commanding general of the 3d Marine Division. “12th MLR is poised to meet the challenges of today and tomorrow, with a vigilant eye on the horizon and a steadfast resolve to protect our nation and support the defense of Japan.”

While forward stationed in Okinawa, Japan, 12th Marine Littoral Regiment will integrate with the Joint Force and the capabilities of our allies and partners, supporting deterrence efforts, and remaining prepared to respond to potential crises.

“12th MLR represents a vital evolution of our mission and capabilities.,” said Col. Peter Eltringham, commanding officer of 12th Marine Littoral Regiment. “We’re proud to be here in the First Island Chain, and a force prepared to respond to contingencies wherever and whenever required. It is our pledge to guard and advance the 12th Marines legacy of honor, fidelity and valor, now as the 12th MLR.”
