Islamic Republic of Iran Army is the conventional ground, air, and naval force component of Iran's regular Armed Forces. It traces institutional continuity from the Persian Cossack Brigade and the Imperial Iranian Army through the 1979 Iranian Revolution into its present form alongside the Islamic Revolutionary Guard Corps. The Army performs territorial defense, conventional deterrence, and support to national policy under the authority of the Supreme Leader of Iran and the Ministry of Defence and Armed Forces Logistics.

History

The force originated with the Persian Cossack Brigade and expanded under the Pahlavi dynasty into the Imperial Iranian Army, participating in events such as the Anglo-Soviet invasion of Iran and modernization programs tied to Reza Shah and Mohammad Reza Shah Pahlavi. After the Iranian Revolution, the Army underwent purges and reorganization during the establishment of the Islamic Republic of Iran. It played a central role in the Iran–Iraq War (1980–1988) alongside the Islamic Revolutionary Guard Corps and took part in key battles such as Operation Tariq al-Qods and the Battle of Khorramshahr. Post-war reconstruction saw procurement efforts involving Russia, China, and indigenous programs like Defense Industries Organization initiatives. The force has since adapted during crises including the Persian Gulf War, tensions in the Strait of Hormuz, and sanctions linked to the Joint Comprehensive Plan of Action negotiations.

Organization and Command Structure

The Army is organized into several principal branches: the Ground Forces, the Navy, the Air Force, and the Air Defense Force. Command authority is exercised through the General Staff of the Armed Forces of the Islamic Republic of Iran, with strategic leadership by the Supreme Leader of Iran and political oversight by the Ministry of Defence and Armed Forces Logistics. Operational coordination occurs with the Islamic Revolutionary Guard Corps and provincial Law Enforcement units. Major regional commands include forces stationed in Tehran, Isfahan, Kerman, Khuzestan, and East Azerbaijan.

Personnel, Training, and Conscription

Personnel include voluntary professional soldiers, reservists, and conscripts subject to Iran's mandatory military service laws administered by the Law on Military Service. Training institutions comprise academies such as the Officers' School of the Army and specialized centers alongside joint staff education with the Joint Staff College. Notable training exchanges historically involved interactions with Soviet advisors, procurement-linked programs with U.S. contractors during the Pahlavi era, and later cooperation with Russian Armed Forces and Chinese programs. Conscription policy impacts demographics across provinces like Fars, Mazandaran, and Sistan and Baluchestan. Career pathways lead to decorations such as the Order of Fath and appointments within institutions like the Ministry of Defence and Armed Forces Logistics.

Equipment and Capabilities

Inventory derives from legacy U.S. platforms procured under the Pahlavi government—examples include Northrop F-5 variants—and later acquisitions from Russia (e.g., Su-24 elements), China (e.g., J-7 derivatives), and indigenous systems like Karrar and Fajr series developments under the Defense Industries Organization. Ground fleets mix Soviet-era equipment such as T-72 derivatives and locally upgraded M60 platforms. Naval capability includes patrol craft, corvettes, and mined areas monitored in the Persian Gulf and Gulf of Oman; air defense employs systems influenced by S-300 negotiations and domestic radar networks. Electronic warfare, unmanned aerial vehicles exemplified by platforms like Mohajer and Shahed 129, and anti-access/area denial (A2/AD) layers contribute to asymmetric deterrence alongside maritime speed-boat tactics associated with IRIN and coordination with IRGC Navy elements.

Operations and Deployments

The Army has conducted major operations during the Iran–Iraq War including urban and marshland campaigns around Khuzestan Province and Shatt al-Arab. Post-war deployments include Operation Nasr-era counterinsurgency and security operations in border provinces adjacent to Iraq and Afghanistan. Naval and aerial units have been active in incidents involving Hormuz transit and United Nations-reported seizures and escorts, interacting with navies such as the United States Navy and Royal Navy. The force has participated in international exercises and provided logistics in humanitarian responses to earthquakes in Bam and Varzaghan, while also contributing to internal security during events such as the 2009 Iranian presidential election protests and border stabilization operations with neighboring states.

Doctrine and Strategic Role

Doctrine emphasizes territorial defense, strategic deterrence, and integration of conventional and asymmetric capabilities inspired by lessons from the Iran–Iraq War. Strategic documents reflect concepts of layered defense, leveraging geography of the Zagros Mountains and choke points like the Strait of Hormuz, and coordination with the Islamic Revolutionary Guard Corps for force multiplication. The Army's role complements Iran's broader defense posture articulated in white papers influenced by interactions with United Nations Security Council dynamics, regional rivalries involving Saudi Arabia and Israel, and strategic relationships with partners such as Russia and China. Contemporary emphasis includes modernization, indigenous production under sanction pressures, and investment in anti-access strategies and electronic warfare capabilities.
