да товарищи да...I was watching "Age of Tanks" on Netflix - a bit dated and somewhat superficial, at the end they talked about the new Russian T-14. So I looked it up, and as I expected, it is not in production, not even really in testing - it sounds like Russia can't afford to put it into production. Sounds like a kewl tank, if they could work out the bugs and put it into production.

I think at this point, from a military perspective, it is the Chinese that would be most likely present a military threat to the USA, if they wanted to - ignoring the cyber attacks by both Russians and Chinese.
