Russia’s traditional war fighting MO has been “keep dying and surrendering in huge numbers until something major happens”.
Crimean War, Russo Japanese War, WW1, Polish-Soviet war, Winter War, WW2, Afghanistan, Chechnya 1.
If not for Lend/Lease giving Russia food, oil, guns, vehicles, bullets, boots and clothing, they would have been rolled back to middle Siberia. For all their hypermacho chest thumping, they’re shit at war.
They seem to be feasting on Russia's ham fisted attempts to bring reinforcement columns along main roads. Russia was completely unprepared for this, and Ukraine obviously was. There is almost no mention of Russian air power operating in this area, and reports that Ukraine brought their own substantial AA assets in case they did. So - you have Russian infantry and armor moving along main roads, in slow convoys, being surveilled by Western satellites the entire time, getting slammed by drones and artillery before they can even get to Kursk.
