so what's going on here? it seems like both sides are just trying to outlast each other. russian forces keep pushing but ukrainian troops hold firm... kinda like a stalemate 
i'm not sure about oleksandr syrskyi saying the enemy is "weakening" though... could be propaganda or just a way to boost morale
but on the other hand, if russian special forces are getting whacked and ukrainian troops aren't budging, maybe there's some truth to it
