Col. Gen. Ramzan Kadyrov, vowed Russian troops would conquer all of Ukraine, and that his troops would not take prisoners in battle, but “we will burn them” all.

Ukraine will. Russia just waiting for the mud to freeze so their armored vehicles don't end up getting stuck, and thermal UAVs having a good time finding anyone trying to hide in - what before had leaves - strips of vegetation.
Pretty much all air defense is used up, lacks ammunition or was simply destroyed (and Ukraine had an insane amount of it on top of recent manpad deliveries).
Meanwhile Ukraine soldiers are sent in truly WW1 fashion style into suicide runs and easily taken out by artillery. Not many fighting capable men are left for Ukraine.
...you have a firm grasp of the situational reality....
