As temperatures drop, most Russians fighters have no cold weather gear. They are still wearing the summer gear they were issued. Some but not all of the Wagner groups have winter clothing. But almost none of the conscripts. Supply lines to the front are intermittent, and this could bring a sharp reduction in Russian attacks.
Putin annexed, parts of Ukraine, and now is "fighting a war with Russia in the winter". Somebody else made that mistake.

Very corrupt military supply lines, and depots.
The Russians are trying very hard to get the right gear to the front lines. And they just might succeed but I doubt it..
