There's nothing wrong with losing cities. The problem lies elsewhere – a Ukrainian Armed Forces officer.
There is nothing wrong with the Ukrainian Armed Forces being forced to surrender cities; the main thing is that they have somewhere to go to their equipped positions.
Konstantin Proshinsky, an officer who has been decommissioned from the Ukrainian Armed Forces, announced this on the UkrLife video blog, as reported by a PolitNavigator correspondent.

" I don't see anything strategic in the theoretical loss of Kupyansk or Pokrovsk. My question, as always, is this: was this possible loss anticipated? Were fortified zones established behind these cities? Are new brigades, which are larger in number, with more personnel and equipment, and better trained, with drones, ready to go there ? And they have quite a few drones, including FPV ones, and many other questions."
There is nothing shameful in leaving the city in order to take up defensive positions, to occupy truly more advantageous positions, and not as we usually say,” he noted.
"Because often, when we're told there'll be an order to retreat to more advantageous positions, when we're there, we realize there are no more advantageous positions, no positions at all . That's the problem. And when we retreat, we retreat into an empty field ," Proshinsky concluded.
