IRGC Ground Forces (Niru-ye Zamini)

The IRGC Ground Forces (Niru-ye Zamini-ye Sepah-e Pasdaran) constitute the largest branch of the Islamic Revolutionary Guard Corps, with personnel assessed at over 150,000. Unlike the conventional Artesh ground forces, which are organized for territorial defense along a traditional military model, the IRGC Ground Forces are structured around provincial commands designed for internal security, asymmetric warfare, and ideological enforcement.

Command Structure

The IRGC Ground Forces are organized into provincial corps (sepah-e ostani), with each corps responsible for its geographic area. This provincial alignment reflects the force’s primary internal security mission — each corps maintains intelligence, operations, and rapid-reaction capabilities tailored to its region. Border provinces (Kurdistan, Sistan-Baluchestan, Khuzestan) maintain reinforced commands due to ethnic tensions and cross-border threats. Specialized brigades — including airborne, special forces, and armored units — are held at the national level for deployment as needed.

Equipment and Capabilities

IRGC Ground Forces operate a mix of domestically produced and legacy equipment. The Karrar main battle tank, based on the T-72 platform with Iranian modifications, represents the most modern armored capability. Anti-tank guided missiles include the Toofan (reverse-engineered TOW) and Dehlaviyeh (based on the Russian Kornet). Armored personnel carriers include the Boragh (M113-derived) and Rakhsh. Multiple-launch rocket systems (Fajr-3, Fajr-5) provide area fires capability. Overall equipment quality lags Western standards, but domestic production ensures supply chain independence from sanctions.

Role and Doctrine

The division of labor between IRGC and Artesh ground forces is deliberate. The Artesh handles conventional territorial defense — border security, combined arms maneuver. The IRGC Ground Forces focus on three missions: internal security and suppression of civil unrest, asymmetric warfare doctrine emphasizing guerrilla tactics and decentralized operations, and serving as a mobilization framework for the Basij in wartime. IRGC ground units regularly conduct exercises simulating urban warfare, counter-insurgency, and defense against ground invasion — scenarios that blend internal and external threats.

Operational History

IRGC Ground Forces have deployed operationally in Syria as advisors and, in some formations, as direct combat forces supporting the Assad government. Domestically, IRGC ground units have been the primary force employed in suppressing Kurdish separatist activity in western Iran and Baluch insurgency in the southeast. Their role in the 2019 and 2022 protest suppression — alongside Basij — underscored their function as the regime’s internal security backbone.
