My guess is that the Ukrainians follow US/Israeli campaign design doctrine which is very much planned to the gnat's level but which allows flexible approaches. You might remember a lot of things were going on in Iraq 1991 and 2003 which were "look at what my hand is doing over here" while other things were happening. 1991 was interesting, because for all the force level that was in the Desert, the USMC and UK did the difficult breaching thing in Kuwait at the same time as the VII Corp strategic envelopment. Having total Air dominance was very nice.
2003 showed that we updated the plan and with fewer forces were able to do the same thing because of information dominance. Now, if the Ukrainians have the same level of information dominance -- assuming there is a pro-Ukrainian partisan with a cell phone (presuming a working cell signal) in every village they will try to liberate -- they might; and if the western IC services are providing world-class strategic pictures of what is happening via their national technical means, Ukraine should be able to do very similarly.
