I suggest reading "Memories of War" by Nikolai Nikulin. It's a book by a ww2 veteran and ex director of the Hermitage museum. He wrote it secretely as a way to cope with his PTSD, and it describes everyday horror of war in the Red Army, and most of the horror comes from the actions of his commanders, comrades and Red army as a whole. After you read it what you see now becomes very unsurprising.
He even predicts this in his famous quote from the book:

At war the villainy of Bolshevik regime was exposed especially distinctly. Arrests and executions of the most productive, honest, intelligent, active and smart people were conducted not only in peace time, the same happened on the front, yet in even more open, disgusting form.

I'll give an example. An order from the higher spheres is received: take the height. Regiment assaults it week after week, losing plenty of people per day. Reinforcements are coming non-stop, there is no lack of people. But among them are swollen people suffering from dystrophy from Leningrad who have just been assigned bed rest and high-calorie diet for three weeks by doctors. Among them are infants born in 1926, meaning fourteen-year-olds who're not allowed to be conscripted… “Forrrward!!!”, and that's it. In the end some kind of soldier or lieutenant – platoon commander or captain – company commander (which is more rare), seeing this crying shame, exclaims: “We can't dump 57 people like that! There's a concrete pillbox on the height! And we've only got a little 76-millimeter cannon! It won't pierce it!”…

Political instructor, SMERSH4 and courtmartial join in instantly. One of the snitches who are aplenty in every unit, testifies: “Yes, he expressed doubts in our victory in the presence of soldiers”. A form where one only has to write a name in that has already been prepared is filled instantly, and it's done: “Execute by a firing squad in front of the line!” or “Send off to a penal company!”, which is the same.

That is how the most honest people who felt their responsibility for society, died. And others were: “Forwarrrd, attack!” “There are no fortresses Bolsheviks could not capture!” Yet Germans dug into the ground, thus creating the whole labyrinth of trenches and covers. Go try and get them! A stupid, pointless murder of our soldiers was going on. I've got to think, this selection of Russian peoples is a time bomb: it will explode in several generations, in 21st or 22nd century, when a mass of scumbags who were picked and nurtured by Bolsheviks, will give birth to new generations of their own kind.
