- The Islamic Revolutionary Guard Corps is Iran’s most powerful security and military organization, responsible for the protection and survival of the regime.
- The Guards are also currently Iran’s most powerful economic actor, reinforcing their influence over political decisions.
- Supreme Leader Ayatollah Khamenei and the Revolutionary Guards have formed a symbiotic relationship that buttresses the supreme leader’s authority and preserves the status quo.
- U.S. and international sanctions against Iran compelled the Guards to support nuclear negotiations. However, they will strongly resist major political and even economic reforms after a nuclear deal.
Overview
The Islamic Revolutionary Guard Corps (IRGC) was created after the 1979 revolution to enforce Ayatollah Ruhollah Khomeini’s concept of an Islamic state ruled by a velayat-e faqih (guardianship of the jurist). The Guards played a crucial role not only in crushing early opposition to Khomeini’s vision, but also in repelling Saddam Hussein’s invasion of Iran in 1980. Since then, the Guards have functioned as both the primary internal and external security force. The IRGC has now eclipsed the Artesh, or conventional forces. It operates substantial and independent land, sea and air forces. It commands burgeoning missile forces. It runs asymmetric warfare through the elite Qods Force and proxy groups, such as Hezbollah. And it would most likely command a nuclear arsenal, if the regime chooses to develop a nuclear weapons capability.
Military and security role
The IRGC has played an important role in suppressing groups that opposed Khomeini’s objectives, such as the Mujahedin-e Khalq (MEK) Organization. The MEK, a leftist group founded in the 1960s, backed the revolution but then split from the theocrats; it was the largest Iranian opposition group until the 2009 election spawned the Green Movement. The Guards were also responsible for putting down various leftist and ethnic insurgencies that broke out after the revolution.

The Guards forces now number up to 150,000 men divided into land, sea and air forces. The IRGC land forces are estimated to number between 100,000 and 125,000. The IRGC’s navy may total as many as 20,000, though some estimates are significantly lower. Another 20,000 are in the IRGC naval forces. And the Qods Force totals around 5,000. The Basij militia, which is subordinate to the Guards, can also mobilize hundreds of thousands of its members to defend Iran against a foreign invasion.
The Guards are also in charge of executing Iran’s strategy of asymmetric warfare in the event of a U.S. or Israeli attack. The IRGC’s secretive Qods Force has trained and equipped proxy groups, such as Hezbollah, Hamas, Iraqi Shiite insurgents, and even elements of the Taliban. Some surrogates have already been used to target U.S. and other Western forces in Lebanon, Iraq and Afghanistan; they could be used against U.S. targets outside Iran in the event of a future conflict.

Over the last decade, Iran’s Revolutionary Guards have trained, equipped, and aided Syria’s security and military forces. Iran has played a crucial role in buttressing President Bashar al Assad, through military advice, provision of weapons, and funding of the cash-strapped Syrian government. Some Iranians have been killed in Syria, including Iranian Revolutionary Guard General Mohammed Allahdadi in January 2015. But Iran does not appear to be committing major ground forces to the conflict. Tehran instead prefers to recruit Shiite militias from across the Middle East and even Afghanistan to fight in places like Damascus and Aleppo. Iran’s profile in Syria is lower than its profile in Iraq.
The Guards have also developed an asymmetric naval strategy for use against the U.S. Navy, which has a superior conventional force. The Guards have hundreds of fast attack boats, anti-ship cruise missiles, and naval mines. Together they impede U.S. operations in the Gulf, disrupt shipping, and impose a painful cost on U.S. forces in the event of an armed conflict. The Guards also operate hundreds of ballistic missiles that can target U.S. forces stationed in Gulf Cooperation Council countries, in addition to Israel and beyond.
The Guards are also Iran’s most powerful internal security force, at times cooperating and competing with the ministry of intelligence and other security organizations. The Guards’ intelligence organization appears to have eclipsed the ministry of intelligence in scope and authority, especially after the disputed 2009 presidential election. Other security organizations such as the Basij and the Law Enforcement Forces have become subordinate to the Guards.
Economic giant
The Guards’ involvement in the Iranian economy began during Ayatollah Akbar Hashemi Rafsanjani’s presidency. Reconstruction of Iran’s economy, battered by nearly 10 years of war and revolution, was one of his major priorities. The IRGC had the manpower to engage in reconstruction activities. Rafsanjani may have also hoped to co-opt the Guards by giving them a slice of the economic pie.
Over the next 25 years, however, the Guards became Iran’s largest economic force. The Guards currently dominate most sectors of the economy, from energy to construction, telecommunication to auto making, and even banking and finance. Khatam al Anabia (the Seal of the Prophets), the Guards’ construction headquarters, is involved in much of the Guards’ official economic activities. But the IRGC is also linked to dozens, perhaps even hundreds, of companies that appear to be private in nature but are run by IRGC veterans. So the Guards’ economic influence activities encompass a broad network of current and former members rather than a single official or centrally administered organization.
The IRGC has taken advantage of its national security authority to extend its control. The Guards prevented a Turkish company from building the Imam Khomeini international airport in 2004 on national security grounds. The takeover of the Telecommunications Company of Iran by a Guards-affiliated consortium in 2009 may have also been motivated by security concerns, especially after the presidential election and subsequent unrest.
The Guards have arguably benefitted from international sanctions and Iran’s isolation, which hurt their domestic and foreign business competitors by increasing business costs. The IRGC’s ability to tap into state funds and its relatively vast independent resources have provided a decisive advantage. Under Ahmadinejad, the Guards were awarded hundreds of no-bid government contracts in addition to billions of dollars in loans for construction, infrastructure and energy projects. Some of the Guards may have become rich from the sanctions regime, but overall the Guards, like the rest of the country, have felt the heavy burden of sanctions. This made the Guards support President Rouhani’s nuclear negotiations despite some of their objections and criticisms.
Political role
The Guards’ rank and file has historically reflected Iranian society and politics at large. Many Guards members supported Khatami in 1995 and Mir Hussein Mousavi in 2009. Nevertheless, the Guards’ top leadership is comprised of conservatives and “principlists” deeply opposed to political reforms. The IRGC leadership’s opposition to Khatami’s reforms was manifested in the “chain murder” of reform intellectuals. The Guards also wrote a letter to Khatami threatening a coup d’etat if he did not rein in the 1999 student demonstrations.


But the Guards are not a united or monolithic force. And not all IRGC members are ideologues. Many respect Mousavi, who was prime minister in the 1980s, for his devotion to the revolution and his conduct during the Iran-Iraq War.

Trendlines
- The nuclear deal could pose a threat to the Guards if Rouhani pursues significant political and economic reforms. While the top Guards echelon mostly supports the nuclear agreement, they are against domestic reforms.
- The nuclear deal could empower Rouhani, but the Guards are likely to benefit from an easing of sanctions and a less economically isolated Iran. The deal, however, is not going to allow Rouhani to completely sideline the Guards from their dominant political, economic, and security roles in Iran.
