Introduction:

Outside analysis routinely treats Iran’s regular military, the Artesh, as a secondary feature of Iranian power. The IRGC dominates attention through missiles, drones, proxy networks, and internal repression, and the shorthand is understandable. It is also misleading. Iran maintains two military institutions with distinct histories, missions, and degrees of regime trust. The Artesh is the larger establishment and remains central to defending Iranian territory, airspace, and waters, yet the regime’s most politically valued and strategically consequential capabilities sit with the IRGC.

The Islamic Republic has long kept the Artesh capable enough to defend the state but constrained enough to limit its independent political weight, reflecting managed subordination rather than neglect. The events of 2025 and 2026 tested that arrangement under fire and, on balance, reinforced it. Two short, intense wars, the June 2025 conflict with Israel and the 2026 U.S.-Israeli campaign, disproportionately degraded the conventional capabilities the Artesh exists to provide, while the regime’s residual leverage shifted toward dispersed, survivable, IRGC-held systems. The death of Supreme Leader Ali Khamenei during the opening hours of the 2026 campaign removed the figure who had balanced the system’s factions and accelerated a drift toward security-military dominance.

This paper assesses the Artesh as it now stands: its composition, its relationship to the IRGC, the regime’s treatment of it, and the consequences of the recent wars for its capabilities and its place in the system. For CENTCOM, the central point is that Iranian military power is not unitary. The Artesh is the instrument of homeland defense; the IRGC is the instrument of cost imposition and escalation. Distinguishing the two bears directly on reading Iranian behavior, calibrating deterrence, and assessing the effects of force.
