Those kinds of reports haven’t been publicized to my knowledge. I will say there are reports of Ukraine looking to draft Ukrainian nationals living abroad which would suggest they’re also having personnel issues. That said, Ukraine hasn’t been using the same meat grinder tactics the Russians have been. My guess is they have pretty significant attrition but nothing like what Stalin Jr has cooked up for Russia.
According to Denise Davidov, during the last month at least one weekly report was like 35 russian loses to 1 ukrainian, counting only vehicles. Anyway, in the last few days ukraine apparently lost 2 Leopards 2, idk if it was confirmed though.
There was an article in a German paper that most of Ukraine's Leopards were out of commission... Probably from lack of maintenance rather than anything else, but still.
As long as russia can keep pushing forward, they won't care about losses. Even by UAF's own admission, they will probably be forced to abandon Avdiivka in 2 months or so at the current rate of things.
The real important question is whether the western political climate turns for the better or worse. If Ukraine would get all the aid it needs and start pushing back, that'd be a whole different situation; but if the aid ebbs, this can turn into another finnish winter war where Russia gets away with annexing a bunch of territory.
