How Iran plans to fight US troops if Trump invades

Tehran has spent four decades and billions of dollars preparing to counter a ground operation


The Telegraph (UK)

Should Donald Trump order American soldiers to seize Iran’s uranium, they would not fight insurgents hiding among civilian populations or terrorists in the shadows.

Instead, they would be up against an enemy unlike any the US military has confronted in a generation: an organised army of hundreds of thousands of fighters who see dying in defence of their homeland as their highest purpose.

Tehran’s army is but one obstacle American special forces would face after Iran has spent four decades and billions of dollars preparing for a ground invasion by the US.

Its defensive architecture is based on multiple interlocking layers, each designed to counter different threats at different ranges and altitudes.

Mr Trump’s plan to seize 450kg of near-weapons-grade uranium, should Tehran decline to give it up, could see the ultimate test of these preparations.

The mission would require hundreds of troops on the ground in Iran at one or more nuclear sites in a high-risk strategy.

US forces would have to fight their way inland and fly over Iran’s mountain defences, sites designed specifically to resist such attacks, package radioactive material while under fire, then fight back through a country where a million people have been mobilised for defence.


Such an invasion plan would require “potentially the largest special forces operation in history”, said James Stavridis, a retired US admiral and former Nato commander.

Iran’s most sensitive nuclear sites occupy positions chosen specifically to complicate American military options.

Each site is more than 600 miles from the nearest potential staging areas – US bases in the Persian Gulf states or aircraft carriers in surrounding waters.

That distance alone is a logistical challenge for any ground or air force attempting to reach, secure and extract material from multiple locations simultaneously.

The terrain also functions as a defensive system. The Zagros Mountains – stretching about 1,000 miles across western Iran with very high peaks – form a natural barrier between the coast and the interior where key sites are located.

Even if American forces somehow reached the exteriors of nuclear sites away from the islands, they would confront the prospect of fighting their way through collapsed tunnels while defenders inside destroyed equipment, and possibly the uranium stockpile itself as a final resort.

Iran’s defensive doctrine relies not on preventing American forces from entering the country – a military impossibility against US air power and capability – but on making any incursion unsustainable through sustained attrition.

“If the US somehow manages to evade attacks and successfully land forces on Iranian islands like Kharg, Bu Musa, or Larak, there remains a fundamental problem with holding them, even for a short period,” state media reported over the weekend.

The primary defensive burden falls on the Islamic Revolutionary Guard Corps (IRGC), which has spent decades preparing the defensive layers for asymmetric warfare against technologically superior forces.

The system evolved from lessons learnt during the 1980-1988 Iran-Iraq war, when Iraqi missile attacks on Iranian cities revealed critical vulnerabilities.

The outermost defensive ring consists of long-range air defence systems designed to detect and destroy threats at extreme distances and altitudes.

The middle defensive layer uses medium-range systems with high mobility, designed to engage fighters, cruise missiles and drones at intermediate distances.

Iran also produces a range of man-portable air defence systems including the Misagh and Shahab Saqeb – lightweight shoulder-fired missiles effective against helicopters and low-altitude aircraft, deployable by individual soldiers for point defence.

A ground invasion would present far greater risks for the US than its air attacks do
It claims to have organised over one million fighters for ground combat, a figure that includes IRGC forces, Basij militia and volunteers.

While actual combat effectiveness remains unknown, the numbers present a challenge for any occupation force.

“The biggest mistake America would make after starting this war would be entering Iran by ground, and it makes no difference whether it’s Kharg Island or any other island,” said Eshaq Jahangiri, the former vice-president of Iran.

“Once upon a time, some countries drew red lines saying they might occupy one of Iran’s islands, and officials during the war responded that ‘occupiers must cross through a sea of blood to occupy one inch of Iran’s soil’. That sentence remains the definitive answer of Iranians.”

If American forces were able to seize nuclear sites, the mission’s objective would be to remove 450kg of enriched uranium.

This is a unique challenge that goes beyond conventional military operations.

Weapons-grade uranium requires specialised handling, transport containers and decontamination procedures.

Forces would need to bring equipment to safely package radioactive material while under potential attack, then transport it hundreds of miles back to secure areas.

The uranium exists in multiple forms at multiple sites.

Some are in gaseous form in centrifuges, while some have been converted to powder or metal for research purposes – and most of it is “under rubble,” after the sites were bombed last year, according to Iranian officials.

Extracting it all would require not just capturing sites but maintaining control long enough for specialists to identify, package and prepare transport material – hours or days during which Iranian forces would concentrate every available asset on preventing exactly that outcome.

Iran has also made clear that any American ground operation would trigger regional escalation.

Military officials warned they would open “other fronts as a surprise” if US troops landed, a threat that encompasses attacks on state infrastructure in the Gulf, American bases across the Middle East and potentially closing the Bab al-Mandeb Strait in the Red Sea in addition to the Strait of Hormuz.

Tehran’s explicit goal is to make any American ground operation in Iran simultaneously trigger costs across the Middle East that far exceed the value of the mission itself.

State media has published analyses suggesting that opening multiple simultaneous fronts would force American commanders to choose between continuing operations inside Iran or defending vulnerable assets elsewhere.

The closest historical parallel may be the attempted rescue of American hostages in Tehran in 1980, which ended in disaster in a desert 200 miles short of the capital.

That mission involved fewer than 200 troops attempting to reach a single location in Tehran and rescue 52 people.

The scale difference between that operation and seizing nuclear material from multiple fortified sites hundreds of miles apart shows the exponential increase in difficulty.

More recent experience in Iraq and Afghanistan demonstrates the challenges of sustained ground operations in hostile territory filled with armed forces ready for martyrdom.

Even with local allies and secure supply lines, American forces found maintaining control over territory costly and difficult.

Iran offers neither friendly populations in most areas nor secure logistics routes from friendly bases.

Defenders fight on familiar ground, operate on interior lines that allow rapid reinforcement, and will fiercely fight for their homeland.

Every tactical advantage seems to belong to Iran. But it is a test neither side has ever faced before.

The UK is crying because they can't atrach to USA to fight terrorists because they are already surrenderd by terrorists.

Europe, especially UK has a very healthy Islamic population. They are afraid of the implosion within their country due to an Islamic uprising if they choose to join the fight.

Cowards that supported Palestine to frustrate Israel and immediately Israel bombed their useless embassy in Palestine they abandoned Palestine instantly...and the State of Israel was born instantly.

This is for other members of separatist groups. Uk is very weak and extremely greedy..and as such are cowards, when confronted directly.

Nuff Said

The UK are wise enough not to sacrifice their children in the baseless war. The IDF should be at the war front first then the UK Army will follow.

The UK is wife enough, they knew Iran is not like Libya or Iraq where they can go and return alive.

The Zionist soldiers should be in Iran first before calling the UK Army.

Ona go wail tire with catarrh dripping through your noses


US is coming and the strait of Hormuz will be opened by force . Goat meat pepper soup go plenty

IRAN that IRAQ inder Saddam ate for breakfast?

Anyway...you have lived a life of poverty ..so enjoy your elevation to stardom for a very brief moment.

You will still return to base.

The funniest thing I read yesterday was Israel telling the US that it will not commit ground troops to any possible US invasion of Iran. Israel has baited the US into a fight but doesn't want to commit IDF soldiers to die. American soldiers will die needlessly for Israel.

Trying to explain the meaning of the word ally on this platform to first radicals then hypocrites or both is an uphill task.

They celebrated when Hezbollah, Chechnyans and the Houthi’s joined in the war, they celebrate Russia and China’s support but condemn the gulf countries for being security and economic partners with the US and Isreal.

Only they can choose who should side with the west.

If England were under any form of attack today Washington would enter the fight without asking questions but the British PM has decided to have English lessons instead.

Ridiculous. The EU and England should be very scared. Their combined military strength is less than that of the US. And as it stands the US weapons and military has been tried and tested yet again and Isreal has proven to be a greater ally and friend to the US.

England,France.. the Entire Europe has been run down by these radicals. Europe is already their turf, conquered territory. No thanks to Obama's Administration, Trumps left to clean up the mess! Imagine enriched uranium, weapon's grade in the hands of these radicals?Interesting times indeed.
