US forces struck Islamic Revolutionary Guards Corp targets in Kermanshah Province, Iran, September 18, killing five IRGC Aerospace Force officers. The Pentagon cited retaliation for Houthi-linked attacks on commercial shipping in the Strait of Hormuz and attempted attacks on US troops. Three IRGC radar installations and one drone storage facility were destroyed. The operation was the sixth US direct-strike action inside Iran since May.

Targets and Casualties
Three IRGC air-defense radar installations and one drone storage depot in Kermanshah destroyed. IRGC Aerospace Force's brigade commander and four communications officers confirmed killed. Iran's state media initially denied casualties, then recharacterized the dead as 'martyrs.'

Strategic Context
Since May 2026, the US has conducted six direct-strike operations inside Iran targeting IRGC infrastructure. Iranian proxy forces have attacked or harassed 47 vessels in Hormuz year-to-date. Oil tanker insurance premiums have spiked over 300% since January — a direct cost that accumulates daily.

Tehran's Response
Supreme Leader Khamenei warned of 'asymmetric retaliation' without naming targets or a timeline. Tehran's previous five warnings in 2026 each ended in limited proxy actions. The Iranian rial fell 3.2% on the news, its lowest level against the dollar this year.
IRGC's attrition rate under this operational tempo is unsustainable. Tehran's response window narrows with each strike cycle.
