I'm not sure Russia really possesses the amount of precision weapons the west does , we never ever see them used very much in any russian conflict that or they are not as Uber as they make them out to be...
But you could be right in that they want to inflict this kind of damage but it's not going to help them to control Ukraine in the long run?
Once Russia have ousted the present Government in Ukraine, the majority of the populace will fall into line.
Yes there will be resistance, but once the majority are behaving, the minimal resistance will be quashed.
