Military Chief of Staff Abdul Rahim Mousavi has been killed, according to Iranian state media as reported by Al Jazeera. He is the fifth senior figure confirmed dead since the campaign began, after Supreme Leader Khamenei, Supreme National Security Council Chairman Ali Shamkhani , Defence Minister Nasirzadeh, and IRGC Ground Forces Commander Pakpour.
The losses span every tier of Iran's command structure. Khamenei was commander-in-chief of all armed forces. Shamkhani coordinated national security policy across military and intelligence agencies. Nasirzadeh directed defence strategy. Pakpour commanded the IRGC's ground forces — the regime's primary instrument of internal control. Mousavi occupied the senior military coordination role between Iran's parallel armed structures — the Artesh and the IRGC — which operate under separate chains of command by constitutional design. The person responsible for making them function as one force is gone.
The three-person interim council formed under Article 111 — Ayatollah Arafi, President Pezeshkian, and Chief Justice Mohseni-Ejei — holds nominal political authority over armed forces whose entire senior leadership is dead. Iran's military doctrine emphasises distributed command, and mid-ranking officers have continued directing retaliatory strikes. But distributed command sustains pre-programmed salvos and localised resistance. It does not sustain the simultaneous coordination of a naval blockade at the Strait of Hormuz, retaliatory missile operations against multiple countries, and the suppression of domestic unrest across a country where security forces have already retreated in some provinces.
