The Role of Armed Non-State Actors in Iran’s Syria Strategy: A Case Study of Fatemiyoun and Zainabiyoun Brigades

Over the past two decades, there has been a growing tendency among Middle Eastern states to use armed non-state actors (ANSAs) as proxies, making them a constant feature of regional conflicts. Fatemiyoun and Zainabiyoun brigades are two recent examples of state-sponsored ANSAs, which have played a significant role as Iran’s proxies in the course of the Syrian conflict. This article seeks to answer the question as to what role the Fatemiyoun and Zainabiyoun brigades have played in Iran’s military strategy in Syria and how effective they have been in securing Tehran’s strategic interests in the war-torn country. The article argues that following the outbreak of the Syrian crisis—as the most critical challenge to Iran’s foreign policy in the Middle East over the past decade—and due to Iran’s restraints in sustaining a large-scale direct military presence in Syria, the two Afghan and Pakistani brigades acted as Iran’s ground forces, reducing human and financial costs of a direct military engagement for Tehran. The effective role played by the two brigades was mainly reflected in the four strategic battles of Aleppo, Southern Syria, Palmyra, and Eastern Syria.
