Not a terrible idea, but idk...wouldn't that put a lot of weight on Sturmpio's shoulders? Building, repairing, sweeping, tank-hunting? You'd need to make at least two every game. It gives it sort of a Panzer Elite feel but I think Sturms should stick to being primarily support/repair units.
It's not like the Shreck is OKW's only source of AT against early light vehicles...I think people have forgotten how good a Puma is in the right hands.
People suggested that a long time ago and I was afraid that would be a problem as well, but it shouldn't be while Volks have a Faust. Then SPs will only have that weight if their player decides to, considering there is a reasonable alternative (Volks+R43s).
That's the thing though, if they are intending to be defensive units, that fancy stock MG34 has the capabilities to suppress anything at range.
A squad with SMGs is excellent at defending an MG from a closing flank.
It's like PGs all over again.
