As this all plays out,the shock of the whole thing is inexplicable,how could Putin have miscalculated so badly for one,strictly by numbers the multi axis plan of attack was poor,ABSOLUTELY EVERYTHING had to go right,and you never expect that in war,NEVER,secondly it's simple numbers,you need at least 750,000 troops to even consider holding all this territory,maybe even a million,not 190,000 that's insane.The Russian military performance is poorer than could ever be imagined,all the way from planning at staff level,tactically in operations,performance of equipment,and morale of troops.
Prior to hostilities I was under the impression that Russia had "professionalized" their military w/contract soldiers and moving away from conscription. Russia soldiers have a track record for being quite formidable,obviously their hearts were lacking at least the conscripted troops,what kind of command structure send troops into battle under the veil of exercises(that is criminal). Russian military doctrine has never put any value on their soldiers lives and this still continues w/recon columns sent into ambushes all over Ukraine,how do you expect loyalty when you dismiss men as cannon fodder,if your a soldier in the West,you are a valuable asset who knows your NCO's,and officers from LT. thru Gen. are not looking to get you killed that makes a big diff. in morale. I just sit here stupified that Russian military doctrine has not seemed to evolve from sledgehammer brute force steamroller machine from WW2.,considering all the examples they could learn from in previous conflicts since then,no evolution=no improvement.In the end it's good because evil is not going to prevail here,but analytically it's hard to fathom.
