“In 1941 Germans had 70 millions populace and 200+ millions in occupied countries as mobilization reserve for army, industry and agriculture. USSR had 180 millions, circa 30% of this number were Central Asians who were illiterate and did not speak Russians. In first weeks of War Germans seized territory with 40 millions Russians, Ukrainians, Belorussians and 70% of USSR industry. 80 or so millions Russians would not be enough to defeat Germans with tactics described by you.”
You say, “80 or so millions Russians would not be enough to defeat Germans with tactics described by you.” Indeed, those tens of millions of Russians did prove themselves incapable of defeating the Axis by themselves while using such tactics. The Western Allies inflicted greater losses on the Axis while using a fraction of the military forces, and they also propped up the Soviet-Russian forces to save them from defeat at the same time.
The Soviet/Russian practice of killing their own Soviet military personnel to compel their suicidal style assaults was conducted for the most part by NKVD, SMERSH, and other special units of the Soviet Army otherwise known collectively as Barrier Troops. See for one quick example:

“Russian POWs were interned in filtration camps to investigate if they did not commit military crimes, about 50 000 of them were convicted. When I was living in one small miners settlement in ole USSR our neighbor was man who was sent to GULAG for serving to German occupants and betrayal of his partisan uncle one former Benderovets and several Crimean Tatars, even they were not executed.”
You are trying to deny the undeniable. Most of the repatriated Soviet POWs who were executed or murdered by the Soviets had nothing to do with Vlasov’s Army or any other disloyal Soviet citizens. They simply had the misfortune of stubbornly surviving the German efforts to exterminate them and being subjected to Stalin’s orders to treat them as disloyal Soviet citizens upon forced repatriation. The British for one example were dismayed to see the Russian POWs disembark from the British transport ship at Sevastopol only to be taken around to the other side of a wall to be shot and killed by the NKVD.
