I hope someone can answer this but i fear that it is very difficult if not impossible to get any kind of accurate information of the sort you are asking out of a fascist police state like current Ukraine. People literally get imprisoned for writing the wrong thing online or having the wrong kind of app installed on their phone that can get them branded as collaborationists. As such it is very unsafe to express how they honestly feel about the war.

This is an extremely paranoid and insecure regime that is getting increasingly violent toward its own people as it loses more and more on the front line and desperately searches for more bodies to throw into the grinder. Paramilitary Nazi organizations that are too ideologically valuable for the regime to lose at the front have taken the functions of internal police, press gangs and punitive detachments.

Any organization of the proletariat right now in Ukraine is deep underground operating in small cells. We occasionally get wind of partisans hitting objects behind the Kiev regime's lines, torching this or that small objective, rumors that they occasionally give the Russians targeting info, etc. but news of any such incidents is highly suppressed by the Kiev regime. They have gotten very good at quickly finding people who post any footage not approved by the regime, and the punishments are extreme.
