US Central Command said on Saturday that it has set up Task Force Iron Gate, a 20-person civilian and military team based in Tampa, Florida. Its job is to work out how advanced weapons, dual-use technology, sanctioned materials and illegal revenue move into and out of Iran by land, and to stop that traffic.
The unit will cover Iran's land borders and the Caspian Sea. Iran shares borders with seven countries: Afghanistan, Armenia, Azerbaijan, Iraq, Pakistan, Turkey and Turkmenistan. Admiral Brad Cooper, the CENTCOM commander, described the task force as an extension of what he called the ironclad blockade the United States already runs against Iran at sea.
A small team with a wide brief
Michael Mulroy, a former US deputy assistant defence secretary for the Middle East, said the value of the unit lies in mapping routes. In his words, it will establish where weapons systems come in, how they could be cut off, and how Iran moves the energy that pays for them. Officials said the team will coordinate with other US agencies rather than act alone.
Analysts doubt it can bite
Several observers are sceptical. The United States has no military presence on the Caspian Sea, so any interdiction there would depend on neighbours such as Azerbaijan or Armenia taking part. Those countries are unlikely to help, according to analysts, because they do not want to damage relations with Russia.
Mohammed Zweiri of Qatar University put the Caspian's share of Iran's economy at about 11 percent, a figure Al Jazeera said it could not verify independently. On that reading, even a partly working blockade of the sea route would leave most Iranian trade untouched. Zweiri argued the task force may end up mostly symbolic.
Strikes, bunkers and a warning
The announcement came during another tense weekend. Iranian state media reported that US projectiles hit Qeshm Island, near the Strait of Hormuz. Iranian officials warned the country could quote rain down hell if attacks continue, while President Donald Trump said he was still open to talks.
The IRGC used the same weekend to announce plans for underground complexes that it says could keep missile and drone production running under bombardment. Satellite imagery reviewed by reporters has shown construction near missile bases. The Wall Street Journal reported that Admiral Cooper and Defence Secretary Pete Hegseth are among the officials urging Trump to approve fresh strikes.
For now the task force has a mandate, a headquarters and a small staff. What it does not have is access to the waterway at the centre of its mission.
