He needs the under-trained conscripts to use as diversions for his loyal trained forces and evil mercenaries to make advancements. It won’t work, but Putin may just kill every Russian citizen before admitting he made a mistake attacking Ukraine for no reason than his own greed. Insane leaders, can never accept defeat, even when it’s staring them in the face. Which is why he held sham referendums that mean nothing to the country he’s invaded.
