THE PUNDIT

The IRGC is not simply an elite military unit, but a constitutionally protected armed and ideological institution built to defend the Islamic Revolution, preserve the ruling order inside Iran, project power abroad, manage Iran’s missile and drone core, and exert influence across politics, intelligence, and major parts of the economy.

What is the IRGC?

The Islamic Revolutionary Guard Corps was created after the 1979 revolution as a force distinct from Iran’s regular military, the Artesh. Its purpose was never only territorial defense. Article 150 of Iran’s constitution explicitly says the IRGC is to be maintained so it can continue “guarding the Revolution and its achievements,” which makes it an institutional guardian of the regime’s ideology, not just the state in the conventional sense. That constitutional role is the key to understanding why the IRGC has become more politically consequential than an ordinary army.

Over time, the IRGC grew from a revolutionary militia into what many analysts describe as the most powerful security organization in Iran. It is Iran’s most powerful security and military organization and also its most powerful economic actor. At the same time, it is the primary body responsible for Iran’s missile and drone arsenals and for managing and supporting the so-called Axis of Resistance that includes Hezbollah in Lebanon, along with other non-state actors across the Middle East.

Why was it created separately from the regular army?

The IRGC emerged because the new revolutionary leadership did not fully trust the conventional armed forces inherited from the Shah. The Artesh was seen as a state army; the IRGC was designed as a revolutionary army. During the Iran-Iraq War 1980-1988, that distinction hardened. The war helped legitimize the Guards as defenders of both the nation and the revolution, and their wartime role became one of the foundations of their later political authority.

That origin explains a basic fact about Iran’s system: there are two military logics operating side by side. The Artesh is closer to a conventional military institution tasked with territorial defense. The IRGC is a parallel force whose mission includes ideological protection, internal security, asymmetric warfare, and regional power projection.

How is the IRGC structured?

The IRGC today includes four main services roughly parallel to branches of a military: Ground Forces, Navy, Aerospace Force, and Quds Force. It also includes other powerful organs, especially the Basij and the Intelligence Organization. The IRGC’s four services parallel the regular military, but also the Guards extend beyond them through intelligence and mobilization bodies.

The Ground Forces are important for internal control as much as external defense. The IRGC decentralized command by creating 32 provincial units able to operate independently if the central leadership is struck, which also makes the force better suited for domestic security and regime survival.

The Navy is especially significant in the Gulf. The IRGC runs an independent naval force responsible for patrolling the Strait of Hormuz, and the Guards developed an asymmetric naval doctrine built around fast attack craft, anti-ship missiles, and naval mines to complicate U.S. operations and threaten shipping.

The Aerospace Force is central to Iran’s ballistic missile and drone capabilities. The IRGC is overseeing Iran’s ballistic missile program, and it is the main institution controlling the country’s missile and drone arsenals.

The Quds Force is the IRGC’s external operations arm. It is the Guards’ de facto external affairs branch, tied to armed groups in Afghanistan, Iraq, Lebanon, the Palestinian territories, Yemen, and elsewhere through training, weapons, money, and military advice.

How is the leadership structured?

The leadership of the Islamic Revolutionary Guard Corps reflects the organization’s hybrid nature as both a military command structure and a political-security institution central to the Islamic Republic. At the top sits Ahmed Vahidi, a veteran IRGC figure with decades of experience across military, intelligence, and state roles. Vahidi is widely associated with the Guards’ external strategic apparatus and later served in senior ministerial positions, making him emblematic of how IRGC commanders often move between battlefield authority and civilian power.

Beneath him, the Guard’s major branches represent Iran’s layered security doctrine. Mohammad Karami, overseeing the Ground Forces, is linked to domestic security, territorial defense, and rapid internal deployment. Majid Mousavi, heading the Aerospace Force, commands one of the most strategically significant arms of the IRGC, responsible for missile and drone capabilities central to Iran’s deterrence posture. Alireza Tangsiri, who led the Navy, became identified with Iran’s asymmetric maritime doctrine in the Gulf, focused on fast attack craft, coastal pressure tactics, and control of strategic waterways. Esmail Qaani, commander of the Quds Force, inherited one of the most sensitive portfolios in Iran’s system: managing regional networks, allied militias, and foreign expeditionary influence.

Together, this leadership structure illustrates the IRGC’s broad mandate. It is not organized solely around conventional warfare, but around four strategic pillars: domestic control, missile deterrence, maritime disruption capability, and regional power projection. The backgrounds of its commanders also show how the Guards cultivate leaders who are not only military officers, but custodians of Iran’s revolutionary-security doctrine.

What is the Basij?

The Basij is a volunteer paramilitary force operating under the IRGC. It is an auxiliary force involved in internal security, law enforcement support, special political and religious events, and morals policing, with branches across nearly every Iranian city and town. In practice, that makes the Basij one of the regime’s most important tools for social control.

The Basij matters because it gives the IRGC depth inside society. The Guards are not only a barracks institution; they have a mass mobilization arm embedded in neighborhoods, universities, workplaces, and local politics. This is one reason the IRGC is harder to isolate than a conventional military elite.

What does the IRGC do inside Iran?

Inside Iran, the IRGC’s mission is regime preservation. That includes intelligence, political signaling, and intervention against perceived internal threats. The Guards became Iran’s most powerful internal security force and that their intelligence organization came to eclipse the Ministry of Intelligence in scope and authority after the protests in 2009.

In September 2024, the U.S. Treasury said Iran’s security forces, including the IRGC and its Basij force, had led the regime’s crackdown on peaceful protests. In January 2026, Treasury again sanctioned officials accusing them of overseeing violent repression.

What does the IRGC do outside Iran?

Abroad, the IRGC is the main vehicle for Iranian power projection. Its method is usually to build influence through allied states, armed movements, militias, logistics networks, advisors, and missile or drone transfers rather than through large conventional expeditionary forces.

The same pattern extends across Iraq, Syria, Yemen, and the Palestinian arena. Iran’s regional networks include Hezbollah in Lebanon, Iraqi Popular Mobilization Paramilitaries, the Houthis in Yemen, and, until the fall of the Assad regime in late 2024, the Syrian state as a key node in Tehran’s networked regional strategy.

Why is the IRGC economically powerful?

After the Iran-Iraq War, the Guards moved heavily into reconstruction and then into major commercial sectors. The IRGC expanded into a vast business network worth billions of dollars, spanning construction, telecommunications, and oil and gas. Treasury has separately identified Khatam al-Anbiya, the IRGC’s engineering arm, as a revenue-generating vehicle owned or controlled by the Guards and involved in infrastructure and pipeline work.

This economic role matters for two reasons. First, it gives the IRGC resources independent of the normal civilian budget. Second, it creates patronage networks that deepen its influence over politics, procurement, contracting, and elite bargaining.

Why do sanctions focus so heavily on the IRGC?

Because the IRGC sits at the intersection of weapons production, regional proxy activity, and sanctions-evasion finance. In February 2026, Treasury said it was targeting networks that helped the IRGC secure precursor materials and machinery for ballistic missile and advanced conventional weapons production, while also identifying petroleum revenues as a major source of financing for repression, proxies, and weapons programs.

The U.S. State Department announced in April 2019 that it intended to designate the IRGC in its entirety, including the Qods Force, as a Foreign Terrorist Organization. In February 2026, the EU formally added the IRGC to its terrorist list, bringing asset freezes and a ban on making funds or economic resources available to it.

Is the IRGC stronger than Iran’s civilian government?

In many critical domains, yes. The key point is not that the IRGC formally replaces the state, but that it penetrates the state so deeply that it often sets the boundaries within which civilian institutions operate. Former IRGC officers occupied key positions across government and parliament. That influence has only become more visible during periods of war, protest, and succession stress.
