The United States has mobilised approximately 2,500 Marines to the Middle East as the war with Iran reaches its 16th day, with the focus of operations shifting toward the strategically vital Strait of Hormuz.
This significant deployment follows a surge in regional hostilities, including recent Iranian missile and drone attacks targeting the United Arab Emirates (UAE).
The deployment consists of the 31st Marine Expeditionary Unit (MEU), which is normally stationed in Okinawa, Japan.
This versatile force, frequently referred to by commanders as “America’s 9-1-1 force,” will operate from a fleet of amphibious warships, including the assault ship USS Tripoli.
As the US military’s primary rapid-response amphibious group, an MEU typically comprises four elements: a command headquarters, a ground combat element (infantry battalion), an aviation combat element, and a logistics combat element.
Its arrival provides the Pentagon with the capability to conduct rapid amphibious raids to neutralise threats to international shipping lanes.
Countering regional threats
The move comes as UAE air defences remain on high alert following repeated provocations. On Sunday, authorities in the UAE successfully intercepted four Iranian missiles and two drones.
In Dubai, residents in the Marina and Al Sufouh districts reported hearing loud sounds linked to these interceptions, while emergency teams in Abu Dhabi recently contained a fire at the Ruwais Industrial Complex caused by a drone strike.
Anwar Gargash, diplomatic adviser to the UAE President, stated that the country has exercised restraint despite facing as many as 1,909 Iranian attacks since the conflict began.
Strategic maritime operations Military planners in Washington are increasingly concerned with Iran’s asymmetric naval tactics. Rather than using large warships, Iranian forces are reportedly deploying fast boats to lay naval mines or launch strikes from islands situated near the strait.
The Marines are expected to counter these threats by targeting missile batteries and drone launch sites, as well as providing escorts for commercial oil tankers. The Amphibious Ready Group supporting the force carries F-35B fighter jets, MV-22 Osprey transports, and heavy-lift helicopters, allowing for strikes both at sea and further inland.
Global implications While the deployment strengthens the US presence in the CENTCOM area of operations – joining the Gerald R. Ford and Abraham Lincoln Carrier Strike Groups – it creates a temporary strategic gap in the Indo-Pacific.
The 31st MEU usually serves as the primary response force for crises involving Taiwan or the Korean peninsula.
Despite the widening scope of the war, Washington maintains that its primary objective is to reopen the Strait of Hormuz, which carries one-fifth of the world’s oil supply, and restore international commercial traffic.
