Qassem Soleimani's death and the prospect of further US-Iranian military escalation raise the question of Iran's military capacity. The Islamic Revolutionary Guard Corps' (IRGC) Ground Forces are Tehran's reserve of last resort for both internal and external security challenges. The Iranian regime goes to great lengths to obfuscate the IRGC's military strength and organization of its ground forces. The Critical Threats Project (CTP) at the American Enterprise Institute (AEI) recently published the groundbreaking report Iran's Reserve of Last Resort: Uncovering the Islamic Revolutionary Guard Corps Ground Forces Order of Battle. In this episode of Overwatch, AEI Resident Scholar and CTP Director Fred Kagan and CTP Iran Team Lead Nicholas Carl discuss their recent report and the crucial role that the IRGC plays in the regime's survival and Iranian efforts to project power and export their revolution abroad.
