Fighters with the Fatemiyoun Brigade, an Afghan Shia militia formed under the Iranian Revolutionary Guard Corps, deployed in the desert south of Deir Ezzor, Syria, on November 5 to fight Islamic State.

This footage, from a pro-Syrian government news outlet, shows the flag of the Fatemiyoun Brigade at about 15 seconds in. Soldiers with their faces covered and with unmarked uniforms stand in formation. A French-made Aerospatiale Gazelle helicopter flies low to the ground at 0:44 seconds in the footage. Iran’s air force is not reported to possess that type of helicopter.

Soldiers can be seen loading a 107mm rocket of Iranian manufacture into a launcher at 0:57 seconds.

The Fatemiyoun Brigade moved from the T2 gas pumping station, located in the desert south of Deir Ezzor toward Al-Bukamal on November 6, Iranian media said.

Iranian Revolutionary Guard Corps and the Fatemiyoun Brigades joined Syrian government forces in their capture of Aleppo in 2016, local media said.

The same pro-government news outlet published footage credited to the Iranian National Guard Corps from fighting in Al-Mayadeen, south of Deir Ezzor city in October. Credit: YouTube/War Media Room via Storyful
