The best Ukraine could try, now, is to race whatever armor they have, west of the Dniepr, to try and pressure the rear and flank of the Russian armored column bearing on their Capital from the west.
Is there a Ukrainian Patton or Rommel?
Wouldn't they be blown to bits, that tank column by the Russian jets?
Remember that war in Georgia? I think it was that war.
There was this tunnel through through a mountain. They did not exploded it to collapse.
The Russians drove over 100 tanks through the tunnel, and won that brief skirmish.
Both sides used the air force, but Russia came out on top with overwhelming force.
It's odd. Recent history just repeating itself here.
Once that amour starts rolling, then they have a plan. Even running away is a plan. Hiding in the city to eventually starve, not really a plan.
