WASHINGTON (VINnews) — More than 2,000 U.S. Marines from the 31st Marine Expeditionary Unit are en route to the Middle East aboard the USS Tripoli amphibious ready group, providing President Donald Trump with additional military options amid the ongoing conflict with Iran now in its third week.

The deployment, redirected from the Pacific with approval from Defense Secretary Pete Hegseth, follows U.S. airstrikes on March 13 that targeted military facilities on Kharg Island, Iran’s primary oil export terminal. Trump described the strikes as having “totally obliterated” more than 90 military targets while sparing the island’s oil infrastructure.

Kharg Island handles approximately 90% of Iran’s crude oil exports and lies near the Strait of Hormuz, through which about one-fifth of the world’s oil passes. Iran has disrupted shipping in the strait, prompting U.S. warnings of further action.

Trump has indicated he could order the seizure of the island or destruction of its facilities if disruptions continue, describing it as leverage to reopen the vital waterway without permanently destroying oil infrastructure. The Marines’ amphibious capabilities — including helicopters, MV-22 Ospreys and infantry — could support operations to secure shipping lanes or establish control over portions of Kharg Island.

Analysts describe a full-scale seizure as high-risk given the island’s proximity to the Iranian mainland, about 15 miles offshore, and potential for strong resistance from Iranian forces. Some reports suggest the deployment raises the possibility of ground operations to secure the facility as an economic pressure point on Tehran.

The USS Tripoli, an America-class amphibious assault ship, is transiting toward the region along with associated vessels, joining other U.S. naval assets already operating in the area.

Trump has repeatedly stated the conflict will end on U.S. terms, while oil markets have shown volatility in response to escalating tensions and threats to global energy supplies.

The situation remains fluid, with U.S. Central Command overseeing operations in the region. No timetable has been provided for the Marines’ arrival, expected next week.
