Best conventional russian weapon?

I was wondering what are some russia's finest weapons in their inventory. And how are they rated?

AK-xx

You know what I mean...

the russian subs

Russian tanks. They are fast,strong and powerful as well as longer range than western tanks.

Russian weapons are classed as T-xx for tanks, for planes and guns the abreviation depends on the manufacturer, for subs it's classed depending on the model plus serial number

Russian tanks are good in overall specs, defensive mesures especially.
And all russian weapons work good without much support ( fuel, amunition ; they carry a lot) plus you have a lot of innovative ideas but what lacks the most is $$$$$

When you feel like levelling a part of someones country accept no substitute:

Smerch-because you're worth it

Ivan russian tanks don't stand a chance against an Abrams sorry to disappoint you.
