I think this goes back to what I have described before as Russian ‘supply box ops ‘.   “Here’s the package of equipment we think you need to get the job done”.

Once the box is empty you’re screwed because you can’t have any more, but the demands on what you are expected to achieve don’t change. That leads to high risk stupid attacks that fail and increases the demand on what supply you have left.
Now you have to wait until Moscow is convinced you deserve a second supply box.
The result is stalemate and it gets harder the second time to change things on the ground.
Kursk may - not because of Ukraine’s actions but because of Russian incompetence- become the very thing Ukraine actually needs it to be now - a drag on Russian forces at little cost to their own.
If they can hold on through winter it will become a stiffer challenge for the Russians.
The stupidity of the Russian command is mind boggling at times. They had this in the bag and screwed it up. Quick thinking Ukrainian tactics in defence resulted in fast withdrawals, avoiding any encirclement disasters. Russia seized almost half of the land lost. And now they’ve been stopped. And they seem utterly at a loss to find the material to carry on.
