SEALs, Rangers, and 972 Pounds of Uranium: Inside the Most Dangerous Military Option in Iran

The Deployment

Several hundred U.S. Special Operations forces — including Army Rangers and Navy SEALs — have arrived in the Middle East, joining thousands of Marines and Army paratroopers already in the region, according to two U.S. military officials cited by the New York Times on March 29. The officials spoke on the condition of anonymity to discuss operational matters. U.S. Central Command declined to comment, according to CBS News.

The commandos have not yet been assigned specific missions, according to the New York Times. Their presence gives Trump military options beyond the ongoing air campaign, including operations aimed at opening the Strait of Hormuz, seizing Kharg Island, or seizing Iran's stockpile of highly enriched uranium at the Isfahan nuclear facility, according to CBS News and the New York Times.

In total, more than 50,000 American troops are now in the Middle East — roughly 10,000 more than usual — according to the New York Times. The force breakdown as of late March: approximately 2,500 Marines from the 31st Marine Expeditionary Unit arrived on the USS Tripoli, along with approximately 2,500 sailors, according to the New York Times. A second Marine Expeditionary Unit is en route from the U.S. West Coast, according to CBS News. Elements of the 82nd Airborne Division — a contingent of under 1,500 service members — were also expected to deploy, according to CBS News.

Aaron MacLean, a CBS News national security analyst and Marine veteran, described the nuclear seizure option in particular: "This would not only be one of the riskiest special operations missions in American history, but very possibly the largest."

The Nuclear Stockpile: What's There and Where

Iran maintains a stockpile of 440.9 kilograms (972 pounds) of uranium enriched to up to 60% purity, according to the International Atomic Energy Agency (IAEA), as confirmed by PBS News and the AP. This is a short technical step away from the 90% enrichment level required for high-yield nuclear warheads, according to the same sources. At 60%, Iran is "the only non-nuclear-weapon State to produce such nuclear material," the IAEA stated, according to WTOP News.

The U.S. significantly degraded Iran's nuclear infrastructure with massive bunker-buster bombs in June 2025, targeting the Fordow and Natanz enrichment facilities and a research site near Isfahan, according to CBS News and WTOP News. However, the IAEA stated following those strikes that some highly enriched uranium could have been moved beforehand. The Bulletin of the Atomic Scientists reported an analysis concluding that Iran may have transferred a large portion — potentially all — of its 60% stockpile to Isfahan before the June 2025 strikes. David Albright, a nuclear weapons expert, told the Bulletin: "Any highly enriched uranium at Fordow was likely gone before the attack."

The uranium is stored in large steel canisters roughly the size of a home propane tank — too large to carry out in a backpack, meaning they would have to be transported on trucks, according to CBS News. At least half of the canisters are believed to be far underground in Iran's Isfahan facility, deep inside tunnels, according to CBS News. The full location of the remaining stockpile was not independently confirmed as of March 30, 2026.

Why the Mission Is Uniquely Difficult

U.S. Special Operations Forces have been training for decades to seize or neutralize Iran's uranium, according to CBS News. They have practiced repeatedly at sites in the United States designed to replicate the tunnels leading to the underground stockpile, according to CBS News. These preparations reflect the fact that this contingency has been planned for a long time — but experts say planning for it and executing it are different problems.

The mission would require getting commandos to a specific underground location deep inside Iran, physically extracting hundreds of pounds of radioactive material under fire, loading that material onto trucks, and then evacuating it — all while Iranian forces respond. Unlike a hostage rescue or leadership targeting operation, the cargo cannot simply be carried by individual soldiers. The transport requirement creates logistical exposure at every stage.

Air bombardment alone may not resolve the problem. A massive air campaign with bunker-buster munitions might entomb the stockpile deep underground, but there is no guarantee the enriched uranium would be eradicated, according to CBS News. Entombing rather than removing uranium risks contamination without certainty of destruction.

CBS News national security analyst Aaron MacLean drew comparisons to two of the most catastrophic special operations failures in U.S. history. Operation Eagle Claw (1980) was the failed mission to rescue 53 American hostages held in Iran after the revolution. After a sandstorm, mechanical problems, and a helicopter collision, the operation was aborted. No hostages were rescued and eight U.S. service members were killed. Operation Gothic Serpent (1993) — the "Black Hawk Down" mission in Mogadishu — attempted to capture a Somali warlord and ended with 18 U.S. Army Rangers dead. Both are cited by current military planners as cautionary examples of what can go wrong when high-risk special operations are conducted in denied territory.

The Diplomatic Alternative — and Why It's Complicated

Before the war began, Iran had indicated a willingness to down-blend its 60%-enriched uranium to 20% purity or below as part of diplomatic negotiations, according to The Guardian's February 21, 2026 reporting. Iran's position at that time was to dilute the stockpile domestically rather than export it — a position that would address nuclear proliferation concerns without conceding physical control of the material to a foreign power.

The U.S. 15-point ceasefire proposal conveyed through Pakistan in late March included demands that Iran dismantle its nuclear program, end uranium enrichment, hand over its enriched uranium stockpile, and limit its missile capabilities, among other demands, according to ISW's March 25 Special Report. Iran's parliament speaker described the proposal as "excessive and unreasonable," according to CBS News.

Trump's stated goal — eliminating Iran's nuclear weapons capability — could theoretically be achieved either by military seizure or a diplomatic transfer. But as of March 30, 2026, the gap between U.S. demands and Iranian counteroffers had not been bridged. Iran has publicly denied any direct talks with the U.S. are taking place, according to CBS News.

The Three Options in the Field

Based on reporting from the New York Times, CBS News, and sources familiar with the deployments, the Special Operations forces now in the region are positioned to support any of three distinct mission types:

1. Strait of Hormuz security. Commandos could be deployed alongside Marines and naval forces to help safeguard the Strait and escort commercial shipping. This is the lowest-risk option and the one with the most immediate economic impact if successful.

2. Kharg Island seizure. A combined amphibious and special operations assault on Kharg Island, Iran's main oil export terminal, would cut off the approximately 90% of Iran's crude exports that transit through the facility, according to NBC News. Trump has openly discussed this option in interviews.

3. Nuclear stockpile seizure. A special operations mission into the Isfahan facility to physically remove Iran's highly enriched uranium. This is the most operationally complex option, carrying the highest risk of casualties and international legal complications, but would directly address the nuclear dimension of the conflict.

The commandos have not been assigned to any of these missions as of the reporting available through March 30, 2026, according to the New York Times. Their presence is described as giving the president options — not as evidence that any of these operations has been ordered.
