Looks like Ukraine has forced Russia into extra time. When you have a motivated and determined nation you have a team. The Russians don't want to be there.
I also don't see individual small detachments sent to do anything. They certainly realised the threat of roaming small units through the countryside full of gorilla warriors. Or... maybe they just noticed how much they lost to AWOL, and desertion?
Russians are starting to entrench in some areas, and retreated from a potential cutoff left of Dnieper.
It will be a question how they will be resupplying theese dugouts far into Ukrainian held territory?
They are starting avoiding fights in some areas, preferring to retreat, and regroup with bigger force.
Artillery, and MLRS got into the field now, and now firing on Ukrainian forces from point blank range.
Certainly, there is a new commander who knows what he is doing.
Still, Russians are severely overextended at their current land gains.
