I love it how Sarg and Arch cover stuff they understand, e.g. western politics, video games, and other aspects of pup culture, but tbh I am less willing to trust them on anything like Real World warfare and Russian military equipment.
That said, it is plausible that some units were slacking off, Russia did this very, very haphazardly and out of the blue, but Russia's "failures" and losses imho have been puffed up out of proportion.
This does kinda-sorta validate my law about Eastern European inventory equipment.
Oh, and btw I think that cartoon parody was Serbian.
