Introduction to the Iranian Army
The Islamic Republic of Iran Army, often simply referred to as the Iranian Army, is the primary conventional military branch of Iran. Its formal name, Arteš Jumhuriye-e Eslâmi-e Irân, is commonly abbreviated as AJA. This institution is fundamentally responsible for conventional military operations, distinguishing it from other military formations within the country. Unlike the Islamic Revolutionary Guard Corps (IRGC), which operates with a strong ideological underpinning, the Iranian Army functions more directly under the auspices of the national government, primarily focusing on traditional defense roles. It is a critical component of the Islamic Republic of Iran Armed Forces, designed to protect Iran's territorial integrity and national interests through conventional warfare means.A Rich Military History and Evolution
Iran's military history is as ancient and complex as its civilization itself. With thousands of years of recorded history, and due to an unchanging geographic and geopolitical condition, Iran (known as Persia in the West until 1935) has forged a long, varied, and often checkered military culture. This history ranges from triumphant and unchallenged ancient military supremacy, which afforded it effective superpower status in its day, to periods of significant challenge and transformation. Prior to the 1979 Islamic Revolution, Iran's military industry was largely limited to the assembly of foreign weapons. American firms such as Bell, Litton, and Northrop established assembly lines in Iran, where Iranian workers put together a variety of helicopters, aircraft, guided missiles, electronic components, and tanks. This period saw a significant reliance on Western military technology and expertise. The Islamic Revolution marked a profound shift. The traditional military, seen by some as too closely aligned with the Shah's regime, underwent significant restructuring and reorientation. A key symbol of this transformation is Iran's annual Army Day, celebrated on April 18. This holiday was established by the former Supreme Leader of Iran, Ruhollah Khomeini, on April 18, 1979, shortly after the revolution. Previously, Army Day was commemorated on February 21 (Esfand 3) to mark the 1921 Persian coup d'état during the Qajar era. This change reflects the new ideological framework guiding the armed forces. The Iranian Army has since evolved significantly, adapting to new geopolitical realities, sanctions, and internal political dynamics.The Dual Military System: Artesh vs. IRGC
One of the most distinctive features of Iran's military landscape is its dual structure, comprising the conventional Islamic Republic of Iran Army (Artesh) and the Islamic Revolutionary Guard Corps (IRGC). While both are integral parts of the Islamic Republic of Iran Armed Forces, they serve distinct purposes and possess different operational philosophies. The Artesh is the traditional military, focused on conventional defense, border protection, and large-scale warfare. It is the primary force responsible for maintaining a standing army, navy, and air force for national defense. In contrast, the IRGC was established after the 1979 revolution to protect the Islamic system and its values. Over the decades, the IRGC has grown immensely in power and influence, extending its reach into various sectors including economic, political, and military. It operates its own ground forces, navy, air force, and intelligence apparatus, often paralleling or even surpassing the capabilities of the conventional army in certain areas.The IRGC's Growing Influence
Today, analysts widely estimate that the IRGC's military and political power now far surpasses Iran’s regular army. The IRGC controls a significant portion of Iran's strategic assets and resources, with estimates suggesting it controls between 20% and 40% of Iran's economy. This extensive control provides the IRGC with immense resources and autonomy, allowing it to develop advanced capabilities, including a vast missile arsenal and unconventional warfare tactics, often through its elite units like the Quds Force. While the Iranian Army focuses on traditional defense, the IRGC is more involved in asymmetric warfare, regional proxy conflicts, and maintaining internal security, reflecting its ideological mandate. This dynamic creates a complex interplay, where the conventional army often finds itself overshadowed by the ideologically driven and politically powerful IRGC.Command Structure and Hierarchy
At the apex of Iran's military hierarchy stands the Supreme Leader, who holds the position of Commander-in-Chief (Farmandehe Koll-e Qova). This is the ultimate authority over all the Islamic Republic of Iran Armed Forces and the highest possible military position within the country. While a formal military hierarchy exists below the Supreme Leader, informal influence networks and interpersonal relationships play similarly prominent roles in how the armed forces function. This dynamic has been reflected by instances where the Supreme Leader, Ali Khamenei, sometimes issues orders directly to the service chiefs, bypassing intermediate command levels. The Joint Staff of the Islamic Republic of Iran Army (Persian: ستاد مشترک ارتش جمهوری اسلامی ایران), acronymed SEMAJA, serves as the chief of staff of the conventional Iranian Army. Its primary aim is to coordinate its four military branches: the Ground Forces, Air Force, Navy, and Air Defense Force. This structure ensures a cohesive operational framework for the conventional army, allowing it to execute its defensive mandate effectively.Personnel Strength and Composition In terms of active troops, the Iranian armed forces are considered the largest in the Middle East. This significant manpower provides Iran with a substantial conventional deterrent. As of 2007, estimates from the Center for Strategic and International Studies (CSIS) indicated that the regular Iranian Army had approximately 350,000 personnel, comprising 220,000 conscripts and 130,000 professionals. Additionally, there were around 350,000 reservists, bringing the total estimated strength to 700,000 soldiers. While these figures provide a snapshot, the exact numbers can fluctuate due to conscription cycles, retirement, and operational deployments. The reliance on conscription ensures a steady flow of personnel, though it also presents challenges in terms of training and maintaining professional standards across the board. The Islamic Republic of Iran Army (IRIA) specifically refers to the ground forces of the military. In Iran, it is also commonly called Artesh (ارتش), which is the Persian word for army.
Budget and Modernization Efforts
Iran's military strength has evolved significantly over the past decades, driven by a combination of internal strategic priorities and external pressures, particularly sanctions. Between 2023 and 2025, Iran significantly increased its military budget, with a substantial portion directed to the Islamic Revolutionary Guard Corps (IRGC). In 2023, Iran's military expenditure was estimated at $10.3 billion. Of this, the IRGC received approximately 37% of the budget, amounting to around $3.8 billion, highlighting the regime's continued prioritization of the IRGC.Challenges to Modernization
Despite increased spending, the modernization of Iran's conventional army faces considerable hurdles. The poor state of Iran's finances, exacerbated by international sanctions, severely limits its ability to make large foreign orders for advanced military equipment. While Iran has made strides in developing its indigenous defense industry, particularly in missile technology and drone production, its conventional forces still grapple with aging equipment and a reliance on older platforms. Along with Iran’s proxies, its conventional forces are believed to have been heavily degraded by Israeli and U.S. military operations over the past year, further underscoring the need for modernization and recapitalization. The recent Russian additions to Iran's military inventory might offer some relief, but the overall picture remains challenging for the conventional army to acquire cutting-edge technology on a large scale.Key Branches and Capabilities
The Islamic Republic of Iran Army is composed of four main branches, coordinated by the Joint Staff of the Islamic Republic of Iran Army (SEMAJA): 1. **Ground Forces (IRIA/Artesh):** This is the largest branch, responsible for land-based operations, border defense, and maintaining territorial integrity. It comprises infantry, armored divisions, artillery, and special forces. 2. **Air Force (IRIAF):** Operates fighter jets, bombers, transport aircraft, and reconnaissance planes. Its fleet largely consists of older generation aircraft, many of which were acquired before the 1979 revolution, supplemented by some indigenous designs and limited foreign acquisitions. 3. **Navy (IRIN):** Responsible for naval operations in the Persian Gulf, Gulf of Oman, and beyond. It operates a range of vessels, including frigates, submarines, and patrol boats, with a focus on asymmetric warfare and coastal defense. 4. **Air Defense Force (IRIADF):** Manages Iran's air defense systems, including radar networks, surface-to-air missile batteries, and anti-aircraft artillery, crucial for protecting Iran's airspace.The IRIAA: Iran Army Aviation
A notable component of the Ground Forces is the Islamic Republic of Iran Army Aviation (IRIAA), more commonly known as the Havānīrūz (هوانیروز). This is the army aviation arm of the Islamic Republic of Iran Army Ground Forces. Havānīrūz plays a vital role in providing air support for ground operations, including troop transport, reconnaissance, and combat support using a variety of helicopters. Its capabilities are crucial for rapid deployment and logistical support in diverse terrains.Strategic Role and Regional Ambitions
The Iranian Army's strategic role extends beyond mere defense. It is an integral part of Iran's broader military doctrine, which emphasizes deterrence, asymmetric warfare, and projecting influence in the region. While the IRGC often takes the lead in unconventional and proxy warfare, the conventional army maintains a significant presence and capability for large-scale operations. For instance, soldiers march during military parades to mark Iran's annual Army Day in Tehran, such as the one photographed on April 18, 2025, showcasing the disciplined and organized nature of the conventional force. These parades serve as a display of strength and a reminder of the army's role in national security. The depth of Iran’s military strategy and its regional ambitions are multifaceted. From elite units like the Quds Force (part of the IRGC) to its vast missile arsenal and unconventional warfare tactics, Iran seeks to protect its interests and exert influence. The conventional army contributes to this by providing a foundational military capability that allows Iran to maintain a credible deterrent against external threats.Is it a Sleeping Giant or Just a Paper Tiger?
The question of Iran’s true military strength often arises: is it a sleeping giant or just a paper tiger? This debate reflects the complexities of assessing a military force that operates under significant sanctions and integrates both conventional and unconventional capabilities. While its conventional forces might suffer from an aging inventory and the impact of sanctions, Iran's indigenous production capabilities, its strategic depth, and its extensive network of proxies provide it with unique advantages. The degradation of its conventional forces by Israeli and U.S. military operations over the past year is a significant factor, but it doesn't necessarily diminish Iran's overall capacity for regional destabilization or defense. The ability of Iran to withstand prolonged pressure and maintain a robust defense posture, despite these challenges, suggests that it is far from a mere paper tiger. Its strategic patience and willingness to leverage asymmetric advantages make it a formidable, albeit unconventional, power in the Middle East.Conclusion
The Islamic Republic of Iran Army, or Artesh, is a vital pillar of Iran's national security, distinct yet intertwined with the more ideologically driven IRGC. It represents the conventional might of a nation with a rich and complex military history, from ancient supremacy to modern-day challenges posed by sanctions and geopolitical tensions. While the IRGC often dominates headlines with its regional activities and advanced weaponry, the conventional Iranian Army remains crucial for territorial defense, maintaining a significant personnel strength and continually striving for modernization despite considerable obstacles. Understanding the nuances of Iran's dual military structure, its command hierarchy, and its evolving capabilities is essential for anyone seeking to comprehend the strategic landscape of the Middle East. The Iranian Army is not just a collection of soldiers and equipment; it is a dynamic institution adapting to an ever-changing world, embodying both the historical resilience of Persia and the revolutionary spirit of the Islamic Republic.
