Several major news organizations reported on the 13th of March of 2026 that the Pentagon has ordered the deployment of elements of the 31st Marine Expeditionary Unit to the Middle East, which consists of roughly 2,200 Marines in addition to the sailors that are manning all of the amphibious ships.

Lastly, the reports also stress that this is just to add flexibility for commanders without necessarily signaling an imminent large-scale ground invasion of Iran itself, though some analysts and commentators have speculated that it could enable operations like securing strategic points
