RU has demonstrated repeatedly that they'll trade space for time and time for a favorable casualty ratio. hard to say how much UA has left in them but the videos of captured Ukrainian POWs (grain of salt for all the obvious reasons) are increasingly desperate, and there has been a noted increase in the rate of Ukrainian officers KIA.
as noted in what will be tomorrow's Third Rail, I fully expect a winter offensive, possibly within the proverbial "next two weeks," but almost certainly before 1 December
