Military analysts say Russian forces are increasingly investigating Ukrainian lines to identify weakened positions before attacking and breaking through.
They did the same thing in WWII, the Soviets would find which portions of the Axis lines were manned by Italians or Romanians and concentrate their attack there.
Keeping a relatively high percentage of troops in reserve so they could be redeployed to exploit weak points was a core part of soviet doctrine. When all you have to do to identify a weak point is look at their flag it makes things a lot easier.
