Iran dual military structure

Iran operates a unique dual military system where the regular army (Artesh) and the Islamic Revolutionary Guard Corps (IRGC or Sepah) function as parallel, often competing, forces.

Core Differences

• Constitutional Mandate: The Artesh is tasked with protecting Iran’s sovereignty and territorial integrity. The IRGC's mission is to safeguard the Islamic Republic's ideological system (velayat-e faqih) and prevent internal "deviant movements" or coups.
• Leadership & Loyalty: While both answer to the Supreme Leader, the IRGC is considered his "personal army," enjoying a higher degree of trust and political influence. The Artesh is often viewed by the regime as more "professional" but potentially less ideologically committed.
• Operational Focus:
  • Artesh: Traditional conventional warfare, border defense, and patrolling the Gulf of Oman.
  • IRGC: Asymmetric warfare, internal security, and regional power projection via the Quds Force (overseas operations) and proxies like Hezbollah.

• The Artesh remains largely focused on territorial defense during this crisis, though U.S. President Trump has reportedly offered immunity to both forces if they lay down their arms.
