The Islamic Republic of Iran Army (Persian: ارتش جمهوری اسلامی ایران‎‎) acronymed AJA (Persian: آجا‎‎), simply known as the Iranian Army or Artesh (Persian: ارتش‎‎ Arteš), is the "conventional military of Iran" and part of Armed Forces of the Islamic Republic of Iran. The army is tasked to protect the territorial integrity of Iranian state from external and internal threats and to project power. Artesh has its own Joint Staff which coordinates its four separate service branches: Ground Forces, Air Force, Navy and newly-established Air Defense Base.

The Iranian government makes a show of military force on Iran Army Day with parades every 18 April, often demonstrating new defense technologies.

The former Supreme Leader of Iran, Ruhollah Khomeini named 18 April as Army Day, calling for military parades to exhibit the nation's military preparedness. The Iranian military honors the country's National Army Day by annual military parading in many cities of Iran every 18th day of April. The biggest march is held in front of the mausoleum of Ruhollah Khomeini.
