No their exercises are entirely different from US training. I listened to too many Russians - too many screaming as they drowned while their commanders urged the rest of them on.
Not saying special, just different.
Perhaps in 50’s. These days they use pretty much the same safety rules during such trainings as the western armies. You can easily find it on YT videos and elsewhere. Kremlin is running a vast psychological operation to convince people in the west that Russian army is some kind of invincible fighting machine and that western governments must stay out of Kremlin's way or else... In fact they made some improvements in recent years but at the cost of size, so Russian army these days is relatively modern, mobile, professional and so on but it is totally unprepared for any large scale invasion. They would be struggling to conquer the whole Ukraine, even more so to hold it. And If they try to enlarge the army keeping the quality, the whole thing is going to implode just like in the 80’s.
