Thousands of soldiers from the US Army’s elite 82nd Airborne Division have started arriving in the Middle East, two US officials told Reuters on Monday, as President Donald Trump weighs his next steps in the war against Iran.

Reuters first reported on March 18 that Trump’s administration was considering deploying thousands of additional US troops to the Middle East, a move that would expand options to include the deployment of forces inside Iranian territory.

The paratroopers, based out of Fort Bragg, North Carolina, add to the thousands of additional sailors, Marines and Special Operations forces sent to the region. Over the weekend, ⁠about 2,500 Marines arrived in the Middle East.

The officials, speaking on the condition of anonymity, did not say specifically where the soldiers were deploying to, but the move was expected.

The additional Army soldiers include elements of the 82nd Airborne Division headquarters, some logistics and other support, and one brigade combat team.

No decision has been made to send troops into Iran, but they will build up capacity for potential future operations in the region, one of the sources said.

Options for Trump

The soldiers could be used for several purposes in the Iran war, including an attempt to seize Kharg Island, the hub for 90% of Iran’s oil exports.

Earlier this month, Reuters reported there had been discussions within the Trump administration about an operation to take the island. Such a move would be highly risky, since Iran ⁠can reach the island with missiles and drones.

Reuters has previously reported the administration has discussed using ground forces inside Iran to extract highly enriched uranium, though that option could mean US troops deeper inside Iran for potentially longer periods of time, trying to dig out material that is deep underground.

The internal Trump administration discussions have also included potentially putting US troops inside Iran to secure safe passage for oil tankers through the ⁠Strait of Hormuz. While that mission would be accomplished primarily through air and naval forces, it could also mean deploying US troops to Iran’s shoreline.

Trump said on Monday the United States was in talks with a “more reasonable regime” to end the war in Iran, but repeated his warning to ⁠Tehran to open the Strait of Hormuz or risk US attacks on its oil wells and power plants.

Any use of US ground troops - even for a limited mission - could pose significant political risks for Trump, given low American public support for the Iran campaign ⁠and Trump’s own pre-election promises to avoid entangling the US in new Middle East conflicts.

Since operations started on February 28, the US has carried out strikes against more than 11,000 targets. More than 300 US troops have been injured and 13 service members have been killed as part of Operation Epic Fury.
