MANAMA, Bahrain — The U.S. Central Command (CENTCOM) confirmed on Sunday, March 29, 2026, that the USS Tripoli (LHA 7) and the 31st Marine Expeditionary Unit (MEU) have officially entered the Middle East area of operations. The arrival of these 3,500 troops—redirected from the Indo-Pacific—comes as The Washington Post reports that the Pentagon has developed detailed plans for ground missions inside Iranian territory.
While the air campaign, “Operation Epic Fury,” enters its second month, the influx of ground-capable forces suggests a shift from purely degrading Iranian infrastructure to potentially seizing or neutralizing specific coastal assets.
The Deployment: Tripoli and the 82nd Airborne
The reinforcement consists of two primary high-readiness formations:
- The Tripoli Group: Centered on the America-class amphibious assault ship, the 31st MEU includes a reinforced infantry battalion, F-35B stealth jets, and Osprey transport aircraft. This unit is specifically trained for amphibious raids and “visit, board, search, and seizure” (VBSS) missions.
- The 82nd Airborne: Approximately 2,000 paratroopers from the Immediate Response Force have also been mobilized. These troops are capable of deploying worldwide within 18 hours to seize airfields or establish forward operating bases.
The “Weeks, Not Months” Strategy
According to leaked Pentagon assessments, any potential ground operation would fall short of a 2003-style “regime change” invasion. Instead, planners are looking at limited, high-impact strikes:
- Kharg Island: Seizing or blockading Iran’s primary oil export hub (90% of its crude flow) to cut off the regime’s financial lifeline.
- Coastal Neutralization: Raids to destroy mobile anti-ship missile batteries and drone launch sites along the Persian Gulf that are currently harassing global shipping.
- Nuclear Material Seizure: Specialized missions to secure highly enriched uranium or sabotage underground facilities that have survived the air campaign.
Washington’s Divided Front
Despite the military build-up, the political path remains murky.
- The White House: Press Secretary Karoline Leavitt stated that while the Pentagon is providing “maximum optionality,” President Trump has not yet authorized boots on Iranian soil.
- The State Department: Secretary of State Marco Rubio told reporters in France that the U.S. expects to achieve its goals in “weeks, not months,” and maintains that ground troops may not be necessary if Tehran accepts a 15-point peace proposal.
- Capitol Hill: Republicans like Senator James Lankford have not ruled out supporting ground raids if the objectives are clear, while Democrats like Senator Cory Booker have labeled the escalation “one of the greatest presidential blunders of our time.”
Tehran’s Ultimatum: “Welcome to Hell”
Iran has responded to the troop arrival with its most aggressive rhetoric to date. Parliament Speaker Mohammad Bagher Ghalibaf warned that Iranian forces are “waiting” for the arrival of American boots on the ground.
“Our men are waiting for American soldiers to enter so they can set them on fire and punish their regional partners forever,” Ghalibaf stated, accusing the U.S. of using diplomacy as a screen for a “secretly planned ground attack.”
In a further escalation, the IRGC has threatened to target American and Israeli university campuses across the Middle East if strikes on Iranian educational sites do not cease by noon on Monday.
