Russia and Ukraine are two countries that have thrown everything they had at each other: from good soldiers, to inmates, to good people who’d probably never held a weapon before.
At this point I imagine that having troops who are alive and actual trained soldiers, not emotionally and physically drained (if not outright mutilated) by years of fighting is a big advantage
If I was taken from my home and suddenly sent to fight for my country, no matter how full of patriotic love I might be, one North Korean child with a knife would be enough to take me out.
yes, this is more like that little hand wave that tennis players do to acknowledge a lucky point “sorry mate, your job is gone… moving on”
