Mass infantry attacks and indifference to troop losses are traditional to the Russian military but are a sign of desperation and near certain failure against the phenomenal destructive power of modern weapons and munitions. In the current context, that illustrates the inability of Russia to adopt modern military methods and that the new offensive will be a bloody failure in a strategic sense. At most, it may make enough territorial gains for Putin to claim victory, which seems to be what he expects to do no matter the cost in Russian lives.
I think he should try to claim victory no matter what happens. Even if Russian forces are beaten out of Ukraine he can say “Missioи Accomplisнед” and claim that NATO was taught a lesson, the dangerous Biolabs were eliminated and then jail whoever disagrees.
There are actually scholars who say that is a canard about Russian troop use in WWII
More accurate about Mao
Or Grant in general
Or Lee ordering the charge at LRT at battle of Gettysburg
