Couldn't find any English sources for this:
Iran uses 73 Ballistic missiles and Shahed-136 drones against 42 targets against Kurdish groups in Iraq. Quite an impressive number of launches.
In case anyone is wondering, former US CENTCOM commander earlier this year claims that Iran has an arsenal of 3000 ballistic missiles.
I didn't expect Iran to have so many honestly, that's a pretty decent sized stockpile for Iran if that number is accurate. The fact they're willing to expend so many against some Kurdish groups means they can most likely replace them quickly. Also, they used Shahed-136 drones so they should be able to mass produced these too if they can spare a bunch to Russia.
This number should help give one a mental check to compare with anytime some think tank claims the PLARF only has a certain number of missiles.
