Given the utter lack of care for their own people and material, I’d suggest much less.

Look at the videos from Avdiivka, they’re literally sending wave after wave of convoys and troops into the same killing zone. It’s absolutely bonkers.

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.
