Various rating systems cannot objectively reflect reality, but, of course, the Russian army is one of the best. Another thing is that in the case of Ukraine it shows itself very strangely, for example, it was obvious to everyone that it was necessary to destroy communications and the energy system of Ukraine, but the fact that the Russian army does it badly suggests some political games behind the screen of a military conflict.

Or, alternatively, with a good army, the Russian command is terribly incompetent.

Even both can be true at the same time.
