The deployment of the Marines could take up to two weeks, potentially placing them in the Middle East by the end of March 2026.
The exercise Iron Fist 26 took place on March 4th, 2026.
WHY:
The deployment is speculated to be related to tensions with Iran and the need to secure the Strait of Hormuz, through which 20% of the globe's oil supply transits daily.

HOW:
The MEU operates as a self-contained, sea-based force capable of launching troops, aircraft, and equipment without relying on nearby bases or infrastructure.
The USS Tripoli is equipped to carry F-35 stealth fighters and MV-22 Osprey transports, as well as landing craft for troop movements ashore.
