In a recently highlighted CENTCOM operation reinforcing the current regional posture, U.S. Marines from the 31st Marine Expeditionary Unit boarded the M/T Celestial Sea, an Iranian-flagged commercial oil tanker in the Gulf of Oman. The vessel was suspected of attempting to violate the U.S. blockade and was redirected. U.S. forces have now redirected over 90 commercial ships to ensure compliance.
