Interesting, Russia is sending T-62s.... this is a tank from 1961. It can only serve for the most basic occupation and civil containment tasks (sending it to fight may also be possible if you want to keep killing your own soldiers). One would thing that "your brothers" are reluctant to be Putinified.
T62s don't have autoloaders, so this is going to be interesting indeed. The rate of killing their own soldiers may go up by 33% - crew of 4 instead of 3.
Also... T62s use 115mm rounds (as opposed to 125mm in T-64/72/etc), which are probably between non-existent and 20+ years old by now. So maybe they won't be firing at all, just used as "live recon" that Russians are famous for.
All they really need is a couple TI-85s to stop the death my miscalculation problem.
