Ukrainian commanders admitted that those offensives of theirs resulted in extremely heavy losses although the government downplayed it later for obvious reasons
I find it unlikely that they would resort to T62's right now, Especially considering Russia does actually have a shit load of T-72's and T-80's stockpiled.
Has the spring thaw mud dried up yet? If it hasn't then I'd suspect the Russians to attempt one last big push if not then they are in a bit of a stalemate.
The Moskva might be salvageable, But regardless its been knocked out of the conflict for the foreseeable future. At this point I'm just wondering how much longer Russia can sustain the clusterfuck.
