Washington is expanding its military options in the Middle East by deploying US Marine units and airborne forces into the operational theatre. Military analysts have described this move as “strategic flexibility”, aimed at maintaining multiple operational pathways on the ground.
An interactive map presented by analyst Mohammad Rammal on Al Jazeera showed the positioning of the amphibious assault ship USS Tripoli, which carries an attack platform capable of operating F-35B fighter jets and heavy helicopters. The vessel is supported by transport and landing ships that provide integrated capability for deploying troops, heavy equipment, and conducting coastal assault operations.
This deployment is complemented by elements of the 82nd Airborne Division, known for rapid deployment and the ability to execute deep parachute insertions. Together, these forces reflect a hybrid operational posture combining amphibious coastal assaults with airborne manoeuvres targeting strategic points behind enemy lines.
Marines as the Spearhead of Intervention
Retired Brigadier General Elias Hanna explains that US Marines traditionally serve as the spearhead in American military interventions. Their structure integrates ground forces, air support, armoured units, artillery, and logistics into a cohesive combat system.
However, Hanna notes that Marine units are not designed for prolonged warfare. Their primary function is to establish a forward operational foothold, or “bridgehead”, enabling larger forces to enter and sustain broader operations.
He adds that combining Marine expeditionary units with airborne forces provides the US command with parallel operational tools:
- Amphibious forces to secure coastal landing zones
- Airborne units to penetrate deeper and seize critical centres of gravity
These operations would be supported by aircraft carriers providing intensive air cover within a wider operational framework.
Reinforcements and Expanding Presence
According to The New York Times, hundreds of US special operations forces have recently arrived in the Middle East, joining thousands of Marines and army paratroopers already deployed.
These forces add to approximately 2,500 Marines and 2,500 sailors who were recently positioned in the region. As a result, total US troop levels in the Middle East have now exceeded 50,000, marking an increase of around 10,000 above typical deployment levels.
Potential Operational Scenarios
Hanna emphasises that the key question is not military capability, but the operational theatre in which these forces may be used. Several scenarios are under consideration:
- Seizing islands that control access to the Strait of Hormuz
- Targeting Khark Island, Iran’s primary oil export hub
- Combining both options to impose simultaneous economic and military pressure
Such actions would aim to disrupt Iran’s strategic and economic infrastructure.
Complex Terrain and High-Risk Environment
Despite these options, Hanna stresses that the operational environment presents significant challenges. Iran’s coastline is extensive, its islands are located close to the mainland, and the Zagros mountain range overlooks key areas.
This geography provides Iran with strong defensive advantages and increases the vulnerability of any deployed forces to sustained fire.
Strategic Posture, Not Immediate War
Hanna concludes that these deployments do not necessarily indicate an imminent large-scale military operation. Instead, they reflect Washington’s effort to build a flexible intervention capability that can adapt to rapidly evolving conditions.
All scenarios remain on the table, but the operational cost and complexity remain high.
Escalating Rhetoric from Washington
In parallel, Donald Trump has intensified his rhetoric towards Tehran, stating that his preferred option would involve seizing Iranian oil and taking control of Khark Island. He also signalled potential military options targeting Iran’s enriched uranium stockpiles and key oil infrastructure.
