So pop cap is the ONLY thing that matters and since weapons don't have pop cap they should all perform the same.... Right?
They all shoot bullets, therefore they should all perform the same.
QED.
Assault Grenadier, Volksgrenadier and Pioneer SMGs are utterly useless, while Allied SMGs are extremely deadly -- not only because of the weapons themselves (Axis SMGs only deal damage in melee range) but also because of the units wielding them (no Axis units get a received accuracy buff when they receive their SMGs, making it impossible to use them as assault troops).
So stats-wise, Allied SMGs have higher DPS and actually work beyond melee range, making them viable, while Axis SMGs have terrible DPS and only work in melee range, making them unviable.
The only unit worthy of mention there is Assault Grenadiers. Not because of damage, but that they fall flat in utility after the first 5 mins of the game. Which reminds me of several other allied units with SMGs as well.
Volks SMG would see use if they didn't get access to STG which are way stronger, even with all the utility they get.
Assault Grens will never be a force to be reckon with if they are CP0. Same problem as Assault Engis.
Volksgrenadier Assault Package
Grants 0.93 received accuracy to the squad
Let's ignore plenty of SMG non ever seen units because they are allied and OP only plays Axis at 4 rank digit...
1-Complains about Pios, even though at 200mp category, they are the best starting engineer in the game. Compare it to RET/CE. RE coming later with stens are still not doing nothing worth mentioning.
2-What are grease guns and what's the point on using a vet 0 vehicle crew.
3-What are Partisans, Assault Guards, Assault Engineers.
The problem with SMGs, is that the moment they are GOOD, you are gonna complain way harder because now the game revolves around running around the map and immediately rushing below 10 range with blobs.
