With an estimated 190,000 active personnel as of 2023, the Islamic Revolutionary Guard Corps stands as a distinct and powerful military force within Iran, operating outside the regular military chain of command. Established in the wake of the 1979 Iranian Revolution, the IRGC was charged with protecting the Islamic Republic’s system, a mission that has since expanded to encompass ballistic missile development, nuclear activities, and support for proxy forces across the Middle East.
Its independent structure and parallel infrastructure have made it a formidable center of power, one that the United States designated as a foreign terrorist organization in 2019—the first time Washington labeled a component of another nation’s military as a terrorist entity.
Origins and Structure
The Guard was created in May 1979 by Ruhollah Khomeini, the founder of the Islamic Republic, to safeguard the new government’s ideological foundations. Unlike Iran’s regular army, which focuses on conventional national defense, the IRGC was designed to prevent foreign interference and suppress internal threats to the revolution’s legacy. Over time, its mandate broadened to include military, political, and economic influence, cementing its role as a major power center.
The IRGC is a multi-service force with separate branches, including the Quds Force, which specializes in extraterritorial operations. Its command structure remains independent, and it reports directly to Iran’s Supreme Leader, giving it authority that often supersedes that of the regular military.
The Guard oversees Iran’s ballistic missile program and is directly involved in the country’s nuclear ambitions, as tracked by international inspectors and intelligence agencies through its participation in uranium enrichment activities. As a primary military and security force under the Supreme Leader, the IRGC now plays a central part in regional conflicts, a role that has drawn sustained scrutiny from Washington.
Regional Reach and the Quds Force
The Quds Force, a special unit within the IRGC, has been the primary vehicle for Iranian support to militant groups across the Middle East. Until his death in 2020, the unit was led by Qasem Soleimani, under whose command it became deeply entangled with Hezbollah in Lebanon, Hamas in Gaza, and the Houthi rebels in Yemen.
These proxy forces have received Iranian support channeled through the Quds Force, extending Tehran’s influence well beyond its borders. Though Soleimani is gone, the Quds Force remains active, continuing its support for these armed groups as part of the IRGC’s broader regional strategy. The Guard’s ballistic missile program continues to advance, and its involvement in uranium enrichment keeps it at the center of international nonproliferation concerns, drawing consistent attention from intelligence agencies and United Nations inspectors.
U.S. Designation and Ongoing Threats
The United States designated the IRGC as a foreign terrorist organization on April 8, 2019, a move that marked the first time the U.S. government labeled a part of another country’s military as a terrorist entity. Since then, the IRGC has been implicated in plots to assassinate former U.S. officials. In August 2022, U.S. authorities disclosed a conspiracy targeting John Bolton, who served as national security adviser under President Donald Trump. The Trump administration maintained the terrorist designation
