It is officially referred to as Arteš Jumhuriye-e Eslâmi-e Irân and is acronymed AJA. This branch is fundamentally responsible for traditional military operations, encompassing ground, air, and naval forces. Its primary mandate is to defend Iran's borders, territorial integrity, and national interests against external threats. Unlike some other military formations within Iran, the Iranian Army functions under the direct auspices of the national government, operating with a focus on conventional defense strategies rather than purely ideological considerations. This distinction is crucial for understanding its unique role within the broader Iranian defense apparatus. ### Distinguishing the Iranian Army from Other Forces Within the complex and layered structure of Iran's military and security establishment, the Islamic Republic of Iran Army stands as one of four dominant forces. It is distinct from other powerful entities such as the Islamic Revolutionary Guard Corps (IRGC), its special operations arm the Quds Force, and the volunteer Basij militia. While all these forces contribute to the strength of the state, the Iranian Army (Arteš) is specifically tasked with conventional warfare, maintaining a more traditional military hierarchy and operational doctrine. This differentiation allows for a division of labor, with the Arteš focusing on national defense and large-scale military engagements, while the IRGC often handles internal security, asymmetric warfare, and ideological protection of the revolution. ## The Broader Landscape: Iran's Armed Forces Structure The overall command and coordination of Iran's military forces fall under the General Staff of the Armed Forces of the Islamic Republic of Iran (Setad-e Kol-e Niruha-ye Mosallah-e Jomhuri-ye Islami-ye Iran). This is the most senior military body in the country, responsible for implementing policy, monitoring, and coordinating activities across the entire spectrum of Iran's armed forces. This includes both the conventional Iranian Army and the Islamic Revolutionary Guard Corps, ensuring a unified approach to national security. ### The Role of the Supreme Leader and Informal Networks At the apex of Iran's military hierarchy is the Supreme Leader, who holds ultimate authority over all armed forces. While a formal military hierarchy exists beneath this supreme command, it's important to recognize that informal influence networks and interpersonal relationships also play a significantly prominent role in how the armed forces function. This intricate web of formal and informal power dynamics can sometimes lead to overlapping responsibilities or nuanced command structures, making the overall system highly adaptable yet complex to outsiders. The Supreme Leader's directives are paramount, shaping the strategic direction and operational priorities of both the Iranian Army and the IRGC. ### Key Pillars of Iran's Military Might As mentioned, the strength of the Iranian state's military and security establishment is constituted by four dominant forces. These include: * **The Islamic Revolutionary Guard Corps (IRGC):** An ideologically driven force established after the 1979 revolution to protect the Islamic Republic. It has its own army, navy, air force, and intelligence wings, commanding an estimated 125,000 troops. * **The Quds Force:** The special arm of the IRGC, primarily responsible for extraterritorial operations and supporting allied non-state actors in the region. * **The Volunteer Basij Militia:** A paramilitary force loyal to the regime, controlled by the IRGC. It serves as a domestic security force, a moral police, and a reserve force for military conflicts. * **The Regular Iranian Army (Arteš):** The conventional military, focused on national defense and traditional warfare, as detailed throughout this article. These four pillars, while distinct in their primary functions and organizational structures, operate under the overarching command of the Supreme Leader and the General Staff, collectively safeguarding the regime and projecting Iran's power beyond its national borders. The increased allocation in Iran's military budget, particularly towards the IRGC and the Iranian Army, underscores their central roles in these strategic objectives. ## Personnel and Manpower: The Strength of the Iranian Army The Islamic Republic of Iran Army (IRIA), specifically its ground forces, forms a substantial part of Iran's military might. In Iran, it is simply called Arteš, which is Persian for "army." Iran boasts the largest armed forces in the Middle East in terms of active troops, a significant portion of which is attributed to the conventional Iranian Army. As of 2007, estimates from the Center for Strategic and International Studies (CSIS) suggested that the regular Iranian Army had approximately 350,000 personnel. This figure was broken down into 220,000 conscripts and 130,000 professionals. Furthermore, the army could draw upon around 350,000 reservists, bringing the total potential strength to an impressive 700,000 soldiers. It is worth noting that some analysts believe these figures are, in fact, far higher, indicating a potentially even larger pool of trained personnel available to the Iranian Army. This substantial manpower, combined with continuous training and recruitment, ensures the Iranian Army remains a formidable force capable of defending the nation's extensive borders and strategic interests. ## Military Ranks and Command Structure The military ranks used by the Islamic Republic of Iran Armed Forces apply across both the Islamic Republic of Iran Army and the Islamic Revolutionary Guard Corps, though each service maintains its distinct insignia and sometimes specific titles for certain positions. This dual-track system reflects the unique nature of Iran's defense establishment, where two major military organizations coexist with overlapping yet distinct responsibilities. The ranks generally follow a structure familiar to conventional armies worldwide, progressing from junior enlisted personnel to senior officers. Interestingly, the ranks used by Iran's law enforcement forces also share a similar structure to the military, indicating a standardized approach to hierarchy and command across various security branches within the country. This commonality in ranking systems helps facilitate coordination and understanding across different segments of Iran's security apparatus. ## Evolution of Iran's Military Equipment and Technology The trajectory of Iran's military equipment and technology has been one of significant transformation, largely shaped by geopolitical shifts and international sanctions. Historically, Iran relied heavily on foreign suppliers for its defense needs, but this dependency has given way to a concerted effort towards indigenous production and innovation, particularly in areas like missile development and drone technology. ### From Western Hardware to Indigenous Innovation From 1925 until the Iranian Revolution in 1979, Iran was primarily equipped with the very latest Western hardware and equipment. Primary suppliers included the United States, Britain, France, and the Federal Republic of Germany (West Germany). There were even cases where Iran was supplied with equipment before it was made standard in the country that developed it, highlighting the close military ties Iran had with Western powers during this period. This era saw the Iranian military acquire sophisticated aircraft, tanks, and naval vessels, establishing a relatively modern conventional force. However, the landscape drastically changed after the 1979 revolution. Iran has been under various forms of sanctions since then, severely limiting its access to international arms markets and spare parts. This isolation forced Iran to become self-reliant, leading to extensive efforts in servicing and overhauling its own military and civilian aircraft, as well as developing indigenous defense industries. This period of necessity spurred significant advancements in local manufacturing capabilities, particularly in areas critical for asymmetric warfare and deterrence. The increased allocation in Iran's military budget today is likely supporting further advancements in key areas such as the development of sophisticated Iranian military equipment, missile technology, and cutting-edge Iranian drone technology. These indigenous capabilities are crucial for Iran's defense strategy, enabling it to maintain a deterrent posture despite continued international restrictions. While sanctions saw a decrease in tension in international relations in 2015, allowing the Iranian government to order a new fleet of civilian aircraft to replace aged types, the core military industries remained focused on self-sufficiency and strategic development. ## Military Budget and Strategic Allocations Iran has significantly increased its military budget between 2023 and 2025, reflecting a strategic prioritization of its defense capabilities amidst regional tensions. In 2023, Iran's military expenditure was estimated at $10.3 billion. A substantial portion of this budget, approximately 37%, was directed to the Islamic Revolutionary Guard Corps (IRGC), amounting to around $3.8 billion. This significant allocation underscores the IRGC's critical role in Iran's defense and security architecture, particularly given its involvement in both internal security and external operations. This increased funding is designed to support advancements in crucial areas such as the development of Iranian military equipment, missile programs, and Iranian drone technology. It also enables continued investment in the operations of core institutions like the IRGC and the Iranian Army, both of which play central roles in safeguarding the regime and projecting power beyond national borders. The budget reflects Iran's commitment to enhancing its deterrent capabilities and maintaining its influence in a volatile region. The focus on indigenous production, particularly in missile and drone technology, demonstrates a strategic investment in areas where Iran has developed considerable self-reliance. ## Iran's Regional Military Posture and Influence Iran's military posture is not solely focused on defensive capabilities within its borders but also on projecting influence and power across the Middle East. The Iranian Army, alongside the IRGC and its Quds Force, plays a vital role in this broader strategy. While the Arteš primarily maintains a conventional defensive stance, its existence as a large, well-trained force provides a foundational layer of deterrence. The IRGC, with its ideological mandate and specialized units like the Quds Force, is more directly involved in supporting regional allies and non-state actors, extending Iran's strategic depth. This dual approach allows Iran to maintain a robust conventional defense while also engaging in asymmetric warfare and proxy conflicts through its revolutionary forces. The development of advanced missile capabilities and Iranian drone technology further enhances Iran's ability to project power and deter potential adversaries without necessarily engaging in direct, large-scale conventional warfare. This strategic blend of conventional and unconventional capabilities shapes Iran's regional influence and its interactions with neighboring countries and global powers. The ongoing dynamics in the region, including the stances of international leaders, continuously influence Iran's strategic calculations regarding its military posture. ## Navigating International Relations and Sanctions Iran's military development and its role in regional security are inextricably linked to its complex relationship with the international community, particularly concerning sanctions. Since 1979, Iran has faced extensive sanctions, which have profoundly impacted its ability to acquire military hardware and technology from abroad. This isolation, while challenging, has paradoxically fostered a strong drive towards self-sufficiency and indigenous innovation in its defense industry. The necessity to service and overhaul its own military and civilian aircraft, and to develop its own missile and drone programs, arose directly from these sanctions. While there was a period of decreased tension and a reduction in some sanctions in 2015, allowing Iran to order new civilian aircraft, the core military sector has largely continued its path of self-reliance. This has led to Iran becoming a significant player in certain military technologies, particularly in missile development and drone technology, which are now key components of its defense and deterrence strategy. The ongoing interplay between international relations, sanctions, and Iran's strategic military investments remains a critical factor in understanding the capabilities and future trajectory of the Iranian Army and the broader Iranian Armed Forces. --- **Conclusion** The Islamic Republic of Iran Army, or Arteš, stands as a formidable and essential component of Iran's defense infrastructure. As the nation's conventional military force, it is tasked with safeguarding Iran's territorial integrity and national interests. Operating distinct from, yet in coordination with, the ideologically driven Islamic Revolutionary Guard Corps, the Iranian Army represents a significant conventional military presence in the Middle East, boasting substantial personnel and a growing array of indigenous military equipment, including advanced missile and drone technologies. From its historical reliance on Western hardware to its current emphasis on self-sufficiency driven by decades of sanctions, the Iranian Army has evolved into a resilient force. Its significant budget allocations underscore its continued importance in protecting the regime and projecting Iran's influence.
