I see MikeyD and others are using lower level math to compute the PPSh-41 rates of fire. Also, how the game models them burning up ammo, etc. They are doing this to prove some tank rider limitations as well as SMG troop issues, etc. basically calling them one-trick ponies once they shoot their wad.
Ugh, it was selective fire weapon. Full Auto and Semi. It was used as such, and on semi, it gave reasonable short range accuracy and a large reserve of magazine capacity. Tank Riders, and most troops, also used enemy weapons but that is not modeled in the game. I am pretty sure they used trucks behind the tanks just like everyone else. It's amazing how these inbred CM 'facts' pop up from these amazing minds at the core of the game. Tank Riders often fought without the tanks!
