That wasn’t even accurate in the Great Patriotic War, it was just Nazi cope to try and excuse their defeat at the hands of a Soviet army that managed to regularly outsmart them and thus appear to have more soldiers than they really did by employing various deception tactics as well as smart use of local numerical superiority. For the first half of the war the Nazis either outnumbered or were on par numerically with the Soviets on the eastern front. The reality is that the Soviets never employed “human wave” tactics because that is not a tactic that can lead to success, it is not viable to throw away your manpower like that.

Unfortunately today’s Ukrainian leadership doesn’t understand that and it is they, not the Russians, who are the ones who have been trying to compensate for the overwhelming Russian superiority in firepower by simply throwing wave after wave of untrained conscripts at the problem hoping to overwhelm with sheer numbers. This results in horrifically skewed casualty ratios. As usual the MO for the pro-Ukrainian propaganda has been projection, projection, projection. If they are accusing the Russians of something you can be virtually sure they themselves are actually guilty of it. This is yet another example of that.
