My favorite Russian military weapon is the not so well known “2K22 Tunguska”.
It’s a frightening multi-purpose all-in-one air-defense vehicle that has multiple ways of taking down short-range enemy flying crafts and ground vehicles.
Its rate of fire is the stuff of horror movies… see it here in action:
I have no idea if the Tunguska has made it into the Ukraine battlefield and haven’t seen any evidence of it, but Russia has such a massive inventory of equipment that only a tiny portion ever makes it into combat.
