Iranian Army is the conventional land force component of Iran's Armed Forces of the Islamic Republic of Iran established in its modern form following the 1921 coup d'état and subsequent reforms during the Pahlavi dynasty. It has participated in major 20th- and 21st-century conflicts including the Anglo-Soviet invasion of Iran, the Iran–Iraq War and regional operations in the Persian Gulf and Kurdistan Province. The force operates alongside the Islamic Revolutionary Guard Corps and coordinates with the Ministry of Defense and Armed Forces Logistics, maintaining peacetime responsibilities for territorial defense, border security and conventional deterrence.
History
The Army traces institutional roots to the Qajar dynasty's attempted modernization and the 19th-century efforts of figures like Amir Kabir and commanders trained in the Ottoman Empire and Imperial Russia. Reorganization accelerated after the 1921 coup by Reza Khan and the founding of the Pahlavi dynasty, which imported doctrine and equipment from France, United Kingdom, and later United States suppliers such as M1 Abrams-class procurement and training exchanges with the U.S. Army. The Army confronted the Anglo-Soviet invasion of Iran in 1941, then experienced expansion and modernization during the reign of Mohammad Reza Pahlavi including ties with NATO partners and purchases from France and West Germany. The 1979 Iranian Revolution precipitated purges and reorientation, followed by the mass mobilization of forces during the Iran–Iraq War (1980–1988), notable battles included the Battle of Khorramshahr and operations such as Operation Mersad. Post-war rebuilding involved domestic production under organizations like the Defence Industries Organization and strategic recalibration after the Gulf War and sanctions regimes.
Organization and Structure
The command hierarchy is under the Armed Forces of the Islamic Republic of Iran with the highest military authority vested in the Supreme Leader of Iran as Commander-in-Chief. The Army comprises branch-level formations: Ground Forces, Air Defense Force, Navy-land components and specialized units including Armored Corps, Infantry Divisions, Artillery Corps and Logistics directorates. Corps and provincial commands correspond to Iran's Ostan provinces, with regional headquarters in cities such as Tehran, Isfahan, Mashhad and Tabriz. Organizational reforms introduced joint command elements similar to structures seen in United States Central Command and Russian Ground Forces to enhance interservice coordination with the Islamic Revolutionary Guard Corps and the Law Enforcement Force of the Islamic Republic of Iran for internal security tasks.
Personnel and Training
Personnel levels have fluctuated due to conscription policies, voluntary service and reserve mobilization; conscription terms are regulated by the Military service in Iran system administered by the Ministry of Interior and the Ministry of Defense and Armed Forces Logistics. Senior officer development occurs at institutions like the Command and Staff College and the War College in Tehran, with historical training links to foreign academies such as the École spéciale militaire de Saint-Cyr and the United States Military Academy predating 1979. Units conduct routine exercises including large-scale maneuvers reminiscent of NATO and WTO-era wargaming—examples include annual drills alongside provincial militias and cooperative events with friendly states like Russia, China and Syria. Specialized schools cover armored warfare, artillery, engineering corps and air defense using doctrine influenced by conflicts involving Iraq, Afghanistan and regional insurgencies in Iraqi Kurdistan.
Equipment and Armaments
Procurement historically involved Western platforms such as Chieftain tanks, Centurion-type tanks, Bell AH-1 Cobra helicopters and F-14 Tomcat fighters, many of which were maintained or cannibalized post-revolution. Domestic industry under entities like the Defence Industries Organization and Aerospace Industries Organization has produced systems including the T-72-derived Zulfiqar tank, Shahab missile variants for army support, and the Ra'ad anti-tank guided missile. Artillery inventories mix towed pieces from Bofors and D-30 howitzer origins with indigenous rocket artillery such as the Fajr-3 and Zolfaghar-family ballistic rockets. Air defense includes legacy systems augmented by locally produced radars and surface-to-air missiles influenced by designs from S-200 and HQ-2 classes. Naval riverine and littoral equipment supports Persian Gulf operations including fast-attack craft and coastal anti-ship missiles derived from the C-802 lineage.
Operations and Deployments
During the Iran–Iraq War the Army fought in conventional campaigns, defensive battles and counteroffensives across fronts like Khuzestan and Iraqi Kurdistan, coordinating with the Islamic Revolutionary Guard Corps and irregular militias. Post-war deployments have included border security actions along the Shatt al-Arab waterway, counterinsurgency in Sistan and Baluchestan Province and cooperation with allied states during the Syrian Civil War via advisory and logistics roles alongside Hezbollah-aligned networks. Naval components have conducted patrols in the Persian Gulf and Strait of Hormuz with frequent encounters involving the United States Navy, Royal Navy and regional navies. Peacekeeping and training missions have been limited but include military diplomacy with Pakistan, Iraq and Turkmenistan.
Doctrine and Strategy
Doctrine emphasizes territorial defense, defense-in-depth, asymmetric complementarities with the Islamic Revolutionary Guard Corps and mobilization of reserve forces such as the Basij-adjacent elements. Strategic guidance references historical lessons from the Iran–Iraq War, deterrence in the Persian Gulf and anti-access/area denial concepts resembling aspects of anti-access/area denial frameworks used by China and Russia. Combined-arms tactics integrate armor, mechanized infantry, artillery and air defense to counter conventional threats from neighboring states like Iraq and to deter interventions by external powers such as the United States and United Kingdom. Emphasis on indigenous production, electronic warfare and missile forces aims to offset sanctions-era procurement limitations and to project influence through military diplomacy with partners including Russia and China.
