Marshal Kliment Voroshilov is pretty bad. Budyonny, at least, realised that the Red Army had to retreat from Kiev (or something like that.)
Whereas Voroshilov was the most swashbuckling, "asskicking equals authority" type of general you could imagine: gunslinging at Panzers, inspiring the men by standing in the midst of artillery bombardments. The trouble was, his generalship was magnificently poor.
Or perhaps Mekhlis, he who didn't allow his troops to dig in so as to avoid a loss of "offensive spirit", and behaved like a Warhammer Commissar, roaring around in a Jeep brandishing a handgun at retreating soldiers, but lacking any other knowledge of military affairs. Or Lazar "Lazarus" Kaganovich, a constantly angry Soviet Commissar, who was a competent administrator, but alas failed to lead his troops with any success. Hilariously, when his staff car was blocked, he went bezerk: "Demote! Court Martial! Arrest! Shoot!" he bawled, in a characteristic rage.
Really, I could go on listing Soviet political leaders who at one time led troops. Many were actually pretty brave-Kaganovich, for example, was wounded by shell fire. But, alas, incompetent when it came to military leadership. Blairwitch, Budyonnoy at least had a moment of strategic inspiration that was entirely absent amongst my other examples.
