Islamic Republic of Iran Armed Forces

The Iranian Armed Forces, officially the Islamic Republic of Iran Armed Forces, are the combined military forces of Iran, comprising the Islamic Republic of Iran Army (Artesh), the Islamic Revolutionary Guard Corps (Sepah) and the Police Command (Faraja).

Iranian Armed Forces are the largest in the Middle East in terms of active troops. Iran's military forces are made up of approximately 610,000 active-duty personnel plus 350,000 reserve and trained personnel that can be mobilized when needed, bringing the country's military manpower to about 960,000 total personnel. These numbers do not include Law Enforcement Command or Basij.

Most of Iran's imported weapons consist of American systems purchased before the 1979 Islamic Revolution, with limited purchases from Russia in the 1990s following the Iran–Iraq War. However, the country has since then launched a robust domestic rearmament program, and its inventory has become increasingly indigenous. According to Iranian officials, most of the country's military hardware is domestically manufactured, and the country had already become an exporter of arms by the 2000s. Unable to import weapon systems from abroad due to international and U.S. sanctions, and suffering from an increasingly aging air force fleet, Iran has invested considerable funds into an ambitious ballistic and cruise missile program for mid-range strike capability, and has manufactured different types of arms and munitions, including tanks, armoured vehicles and drones, as well as various naval assets and aerial defense systems.

Iran's ballistic missile and space program is an internationally hot political topic over which it has consistently refused to negotiate. Iranian authorities state that the country's missile program is not designed to deliver nuclear payloads, but is used only for surgical strikes. It is therefore not relevant to any nuclear negotiations with the P5+1.

The Iranian drone program has also raised concerns across the Middle East and much of the Western world, especially with proliferation among Iranian-allied forces in the Middle East, as well as exports to countries hostile to the U.S. According to U.S. Central Command chief Gen. Kenneth McKenzie, the U.S. is "for the first time since the Korean War operating without complete air superiority" due to threats posed by Iranian drones.

All branches of the armed forces fall under the command of the General Staff of the Iranian Armed Forces. The Ministry of Defense and Armed Forces Logistics is responsible for planning logistics and funding of the armed forces and is not involved with in-the-field military operational command. The commander-in-chief of the armed forces is the Supreme Leader.

The dual military structure of the Artesh and the Islamic Revolutionary Guard Corps (IRGC) has led to structural inefficiencies, with redundancies in command, logistics, and military systems across all branches, including air, naval, and ground forces. This setup has been criticized for its lack of transparency, limited parliamentary oversight, and its questionable contribution to national defense.
