Is it? These are not individual Russian platoons hiking through the woods, Vietnam-style - we are seeing "traditional logistics warfare" that follows major roads towards large cities and infrastructure chokepoints. I - armchair general - would have expected finding the enemy would be relatively easy in that case: Just get a street map and trace major roads back to the (belo)russian borders...

Yes, Ukraine is very flat yet the Russians seem to stick to the roads rather than fan out. Probably due to some combination of time pressure from commanders and fear of running out of fuel. Sure makes the job easier for drones.

It is spring/winter in Ukraine, going offroad means getting stuck in mud. Already there have been photos and videos of Russian vehicles abandoned after attempting to cross fields and such.

The pictures I see are mostly snow & cold, but yes, General Mud is friend of all forces defending against mechanized forces.
