Wouldn’t want to be on the Russian team delivering and installing them. How do you say “sorry, you are collateral damage, tovarisich!” in Russkie?
Boomski.
Most likely the Iranian operators will be trained in Russia, and the system connected to the Russian defense grid.
There will be a period of a year or two. once they are in Iran. before they become combat ready.
The actual system delivered depends on the missiles that Russia is willing to export - usually not their best.
Tough shitski.
