I have been thinking and discussing with others about the performance of the Russian military. If we take their communication equipment; the Russian army has used civilian cellphones for communication, which is a really bad idea in a war zone. They did the same in Chechnya and in Georgia, so why don't they have military graded communication equipment. Can it be corruption? They must have known about it and probably tried to get good communication, but the money might ended up somewhere else.
The performance of the Russian military made me really questioning their military training. It is the same here. To train and having exercises cost a lot of money. The commanders might have used the funding for exercises to something else.
I found this video by the same guy that talked about the German army
