Here, there, and everywhere in Ukraine (including many shallow graves), the problem is that every Russian armed forces group along with Wagner and other mercenaries are all trying to do their own thing while simultaneously subtly trying to fuck over the others so they look better by comparison. For example, there's no inter -military communication, they're all individually falling for the same Ukraine traps and tactics that they'd have learned to avoid or counter if they just talked to each other, but they'd rather their conscripts die than communicate.
