The latest advances further south, yet way more north than I suggested likely, of the Russians with 150.000 operating soliders must be more than only numbers against a by now battle hardened Ukrainin force.
That's superior tactics embedded in a winning strategy.
They do not move major forces to Kursk, but let Ukrainian logistics overstretch the frontline supplies.
If the Russians still have the USA Vs Russian Ice Hockey teams spirit they will have way less stress and disputes among their own, but in crisis even ever more solidarity and support cruxial in Special Forces platoons as much as in long distance supply lines.
Social Skills win wars, not numbers.
If the Russians also continously improved recruit training and gave, as US forces in Iraq, continuously tactical lessons to their front line soldiers, they might have in at least parts created unites with inbetween Elite and Regular Infantry skills that are just more effective in combat than stressed out, always deployed, constantly shelled troops turning hard, but having to retreat at some point with no added theory lessons in their combat time.
