I think the situation in Kherson Oblast is a little different - it’s been flipped whereby it’s the Russians who are entrenched in static defensive positions and it’s the Ukes who have the advantage of fire and manoeuvre.Well thats classic Blitzkrieg you talking, or in proper German term a "Bewegungskrieg" (Maneuver Warfare), basis of all German/Prussian strategy since 18th century.
Problem is that they are fighting opponent who outnumber them in all important components of that strategy, air, armor and artillery, and not Iraqi who were surrendering en masse first chance they got. And of course a drones, they are absolute game changer, they make artillery so much deadlier and accurate.
When Germans were rolling up everyone at the start of WW2, they had advantage in all main three main components (air, armor and infantry), when Americans crushed poorly equipped Iraqi army, they again had massive quality advantage, Ukrainians on other hand are still grossly outnumbered in artillery, armor and air power.
The Russian advantage in numbers and equipment has been all but nullified by Ukraine over the past few weeks. They’ve destroyed Russian fuel and ammo dumps blown all the bridges across the Dnipro severely damaged Russian EW and C2 capability as well as degraded Ru AD in and around Kherson.
Russia still has more of everything but they are struggling now to resupply anything west of the Dnipro.
Time now for manoeuvre warfare - encircle Russian troop concentrations - who are short in supplies and ammo then pick them off.
IMO Ukranian CAS will play a big part over the next week or so.
