Interesting Guards Tank Army to be equipped with T-72s and T-80s. Guess that is because all the T-90s in Syria? /
The Western Europeans would surrender at the mere sight of any Russian tanks coming their way.
In a few years they will likely receive T-14s, as the upgraded 80 & 90s will be pushing obsolescence by then.
The T-90 is a limited production tank currently undergoing real world battle testing. Any lessons learned will go into the T-14 family of vehicles.
Meanwhile, the US is falling so far behind in both tank and plane design that it will likely - at some point - be buying Russian made gear out of necessity.
Someone is likely to say that DJT will change that, but right now he cannot win the General, and even then there is such a horrible education system in the US that any future weapon designers will arrive on H1Vs - while Millennials flaunt their degrees in feminist studies and practice being CEOs in their parents basements.
An upgraded Russian T-72 is the T-90.
