Indeed they are.
Evil.
But what's referenced in the video and the narrative about it is quite tame.
I'm sure what DIDN'T make the video is more severe. As would be treatment of POW's/Insurgents universally in that part of the world.

It’s tame by Russkie standards. There are pictures of people with chopped off heads, or with their bodies burned up. But, rarely do we ever have them video taping their treatment of prisoners. Usually they just find the bodies in the rivers or in the woods.
