Around 2,200 Marines from the 31st Marine Expeditionary Unit have been ordered to deploy to the Middle East amid the ongoing conflict with Iran, according to ABC News.

They will deploy alongside the Tripoli Amphibious Ready Group, which includes the USS Tripoli (LHA-7), USS San Diego (LPD-22), and USS New Orleans (LPD-18), supported by roughly 20 F-35B Lightning II aircraft.

The USS Tripoli and the 31st Marine Expeditionary Unit are forward-based in Sasebo and Okinawa, Japan.
