300k? You mean 30k right?

Iranian official numbers are 3.5k. the OSINT community say at least 15k in the 3 biggest cities (including peo-regime guardias of the revolution), and 'local' journalists (a lot with CIA ties though), not friend of the system say 30k.

I wouldn't trust Iran with a butter knife, so I imagine between 15 and 30k, including 1 to 2k 'guardians'
