TEHRAN, July 21 — The Islamic Revolutionary Guard Corps was born in 1979 with a single mission: shield the Islamic Republic’s system. Four decades later, it operates as a parallel military machine with its own army, navy, air force and intelligence wing — a state within a state, armed with missiles that can reach Israel and parts of Europe. Think of it like this: Iran’s conventional military is the country’s official armed forces.
The IRGC is a separate, ideologically loyal branch that answers directly to the Supreme Leader. Its special operations unit, the Quds Force, handles everything beyond Iran’s borders — training and arming proxy forces in Syria, Iraq and Yemen.
The practical upshot is that the IRGC, not Iran’s regular military, holds the keys to the country’s ballistic missile arsenal. Those missiles — the Shahab, Emad and Khorramshahr variants — have ranges up to 2,000 kilometres. In plain terms, that puts Israel well within striking distance and brings the outskirts of southeastern Europe into range, too.
On April 8, 2019, the United States designated the IRGC a Foreign Terrorist Organization. It was the first time Washington had labelled a part of a foreign government as a terrorist group.
The designation froze any assets the IRGC held under U.S. jurisdiction and made providing material support to the group a crime.
Why it matters beyond the Middle East
The IRGC’s reach extends far beyond Iran’s borders. In Syria, it has deployed advisers and fighters to prop up the Assad government. In Iraq, it has trained and equipped Shia militias that have periodically targeted U.S. forces.
In Yemen, it has supplied the Houthi movement with drones and missile technology. Here’s what it means for ordinary readers: every time a missile or drone strikes a Saudi oil facility, a U.S. base in Iraq or a ship in the Gulf, the trail often leads back to the IRGC.
The U.S. and Gulf states view the corps as a major destabilizing force in the region — not a rogue militia, but a formal arm of the Iranian state. One analogy that helps: imagine if the U.S. Marine Corps also ran its own intelligence agency, its own ballistic missile program and its own covert action network in foreign countries. That is essentially how the IRGC operates inside Iran’s power structure.
The Quds Force, the special operations arm, is the most secretive piece of the puzzle. It handles extraterritorial operations and proxy support — meaning it is the unit that meets with Hezbollah commanders in Beirut, smuggles weapons to Houthi fighters in Sanaa and coordinates with Shia militias in Baghdad.
The U.S. assassination of Quds Force commander Qasem Soleimani in January 2020 underscored just how central that unit is to Iran’s regional strategy.
What to watch next
The IRGC’s ballistic missile program remains a flashpoint. Even as Iran has engaged in nuclear diplomacy, the corps has continued to test and display new missile systems. The range of 2,000 kilometres is not static — longer-range systems have been rumoured for years.
The question, from Washington’s perspective, is whether any future deal with Tehran can constrain the IRGC’s missile arsenal without the corps itself derailing the agreement. For now, the IRGC remains both a military force and a sprawling economic empire inside Iran, with ties to construction, telecommunications and banking.
Any attempt to roll back its influence will have to contend with the fact that it is woven into the fabric of the Islamic Republic itself.
