Military - note

the Islamic Revolutionary Guard Corps (IRGC) was formed in May 1979 in the immediate aftermath of Shah Mohammad Reza PAHLAVI’s fall, as leftists, nationalists, and Islamists jockeyed for power; while the interim prime minister controlled the government and state institutions, such as the Army, followers of Ayatollah Ruhollah KHOMEINI organized counterweights, including the IRGC, to protect the Islamic revolution; the IRGC’s command structure bypassed the elected president and went directly to KHOMEINI; the IRGC played a critical role in helping KHOMEINI consolidate power in the aftermath of the 1979 revolution, and it ensured that KHOMEINI's Islamic revolutionary vision prevailed against domestic challenges from nationalists and leftist factions in the scramble for control after the Shah's departure; the Iran-Iraq War (1980–88) transformed the IRGC into more of a conventional fighting force with its own ground, air, naval, and special forces, plus control over Iran’s strategic missile and rocket forces; today, the IRGC is a highly institutionalized and parallel military force to Iran’s regular armed forces (Artesh); it is heavily involved in internal security and has significant influence in the political and economic spheres of Iranian society, as well as Iran’s foreign policy; on the economic front, it owns factories and corporations and subsidiaries in banking, infrastructure, housing, airlines, tourism and other sectors; its special operations forces, known as the Qods/Quds Force, specialize in foreign missions and have provided advice, funding, guidance, material support, training, and weapons to militants in countries such as Afghanistan, Iraq, Syria, and Yemen, as well as extremist groups, including HAMAS, Hizballah, Kata’ib Hizballah, and Palestine Islamic Jihad (see Appendix T for additional details on the IRGC and Qods Force); the Qods Force also conducts intelligence and reconnaissance operations 

the Supreme Council for National Security (SCNS) is the senior-most body for formulating Iran’s foreign and security policy; it is formally chaired by the president, who also appoints the SCNS secretary; its members include the speaker of the Majles, the head of the judiciary, the chief of the Armed Forces General Staff (chief of defense or CHOD), the commanders of the Artesh (regular forces) and IRGC, and the ministers of defense, foreign affairs, interior, and intelligence; the SCNS reports to the supreme leader; the supreme leader is the commander-in-chief of the armed forces

the Iranian Armed Forces are divided between the regular forces (Artesh) and the IRGC; the Artesh primarily focuses on defending Iran’s borders and territorial waters from external threats, while the IRGC has a broader mission to defend the Iranian revolution from any foreign or domestic threat; in 1989, Iran established the Armed Forces General Staff to coordinate military action across both the Artesh and the IRGC; Iran also has a joint military headquarters, the Khatam ol-Anbia Central Headquarters, to command the Artesh and IRGC in wartime

the Artesh Ground Force consists of about 50 combat brigades, mostly infantry with a sizable contingent of airborne, armored, commando, mechanized, and special operations forces; most units are concentrated along the Iran-Iraq border, reflecting the force’s primary mission to defend against foreign invasion; the IRGC Ground Force is organized into 31 provincial corps and a Tehran city corps, which are postured to counter internal unrest and a ground invasion; the corps have a broad mix of armored, infantry, mechanized, and commando units; the IRGC’s special operations forces are known as the Qods Force; the IRGC controls the Basij Paramilitary Forces, which are also organized into provincial corps with mobile/rapid-reaction, security, infantry, and commando battalions

the Artesh Navy is considered Iran’s “blue water” navy and has the primary mission of defending Iranian territorial waters and protecting the country’s economic interests in the Caspian Sea, Gulf of Oman, and beyond; it has approximately 10 frigates and corvettes, plus a small force of attack and midget submarines (note - Iran is the only Persian Gulf nation with a submarine force); the IRGC Navy is tasked with protecting primarily the Iranian littoral waters in the Persian Gulf and Strait of Hormuz and employs a force of mostly small, fast attack vessels armed with a variety of weapons systems including anti-ship missiles 

Iran’s air and air defense capabilities are split primarily across three services: the Islamic Republic of Iran Air Force (IRIAF) and the Islamic Republic of Iran Air Defense Force (IRIADF), both under the Artesh, and the IRGC Aerospace Force (IRGCASF); the IRIAF operates the majority of Iran’s combat aircraft and has more than 200 such aircraft, a considerable portion of which are older US models acquired before the 1979 revolution; the remainder includes older Chinese-, French-, and Russian-produced aircraft; the IRIADF controls the country’s surface-to-air missile capabilities; the IRGCASF operates some ground attack aircraft and most of Iran’s unmanned aerial vehicles; it also controls Iran’s cruise and ballistic missile force (2023)

Maritime threats

the Maritime Administration of the US Department of Transportation has issued a Maritime Advisory (2023-003 - Persian Gulf, Strait of Hormuz, Gulf of Oman, Arabian Sea, Gulf of Aden, Bab al Mandeb Strait, Red Sea, and Somali Basin-Threats to Commercial Vessels) effective 23 February 2023, which states in part that "Regional conflict, military activity, and political tensions pose threats to commercial vessels operating in the above listed geographic areas;" Coalition Task Force (CTF) Sentinel has been established to provide escorts for commercial shipping transiting the Persian Gulf, Strait of Hormuz, and Gulf of Oman
