I read about the successive attempted reforms on Wikipedia. And, unfortunately, I don’t think Putin has an effin’ clue about military organization or structure, units or formations, tactics or strategy. He has to trust the opinions of the incompetents he’s surrounded by! It will be, truly, mind-boggling if Putin’s Russia is undone by this unnecessary misadventure!
The Russians can learn from their mistakes if anything. Several pages back there is an article written by ex-PLA seems convincing for me. Their actual BTGs is actually decent, the problem is Russia can't afford many of them, and making everyone adhoc BTGs is clearly not working. BTGs being heavy on big guns light on logistics proves to be inadequate for long distance maneuvering.... no doubt they're gonna have to work on that.
And lets not kid ourselves, Russia is not gonna collapse from a little military misadventure, they practically do this every decade
