An illiterate confederate general (who founded the KKK) once described battle as "firstest with the mostest" and that is how this war is shaping up. Vlad feed his entire force into the meat grinder scrapping up people where ever they could find them, from some of the prisoner interviews. He is having trouble finding combat troops to feed in and is hiring mercenaries out of desperation. He had no plan B, it takes time to assemble forces and move them, he dare not call up the reserve and he invaded at the worst possible time. He is having well documented logistical issues and the Ukrainians are focused on making them worse and he is a very bad strategic position in the country with his forces scattered around. He is also getting checked and beaten back around western Kyiv and being constantly drained and worn down. The Ukrainians have almost equal forces in the country and are training many more with NATO help and they will get to the fight before any help that Vlad can provide will. Chinese MRE's are one thing, trucks to get them into Ukraine might be another.
I might seem optimistic, because I try to look at the problems, many times, from the Russian's perspective and even Vlad's. Try to see the world through their eyes, the problems they face and fear. Also I know about or suspect the many things the Ukrainians are doing that we don't hear about on the news, but are sometimes mentioned in the media by the generals on TV. I speculate, but that's why many are here, to speculate, discuss events and possibilities.
