As unfair as that is, Russians can still rely on basically volunteers who an average choose to be there, Ukrainians do not. I've heard many horror stories from there. About men who are basically hiding in cellars so that the recruteers won't pull them off the streets.
Fucked situation all around. I want to blame Russians as the only ones responsible for that, I guess. (As in they started this. Not saying Ukraine is crystal clear with many issues they have with the army, but still I can't blame them.)
I'm Pole, so it's more personal for me. Knowing if I was born a bit more to the East, I'd be awaiting my death (and in agony).
