That's not even completely true. It was partially directed at officers, but who do you think was doing the retreating? The soldiers. So, using a commissar to halt a retreat all the way back to base does in fact fit with the spirit of Not One Step Back. Which, again, nobody had implied that the commissar would be shooting the troops, just that they would halt them from retreating further. And that, again, fits wholly within the verbage of the order.
Watch the video again. Mass disorderly retreats are the officer's responsibility, which is what 227 covers. Individual retreats is classified as desertion. If it's down to the individual, then it falls under desertion, which is court-martialing and potential execution, just like
any other army. In CoH2, the officer (you) is ordering the retreat. It's not desertion or disorderly mass retreat.
No other faction requires any misunderstood historical precedents to justify an FRP. Why should the Soviets need one?
I think everyone can agree Hollywood films are very inaccurate, and a good chunk of them are mostly propaganda. Nor do I think that is a very good film, but Russians shooting other Russians? That happened. Russia suffered the biggest military losses in history during WW2. A lot of which had to do with their suicidal tactics
Of course it happened. Russians shooting Russians did happen, as did Americans shooting Americans or Germans shooting Germans for desertion. If you watch the video, it highlights just how small a fraction the executions were in comparison to the total Soviet military. While I won't deny that the number sentenced was far higher than other nations, execution was far from a unique phenomenon. The higher numbers of executions owe in large part to the size of the army involved as the scale of ground combat on the Eastern front was far, far larger than the Western front.
You should educate yourself some more about these supposed suicidal tactics. That's just as much propaganda as the rest of it. If you don't like TIK, Military History Visualized has a
decent video about all these silly Red Army myths that amateurs keep throwing around. The portion about Red Army's 'human wave tactics' immediately follows his own take on Order 227.
The reason (my guess) is that it is because Sturm Officer has to reach vet 5 to get the Stg44 as opposed to vet 3
I'd argue that the StG is far more valuable a weapon than the PPSh. I get the rest of the squad has SVTs, but honestly I just want the PPSh for visual change and variety.
