It's not about them HAVING SMGs. It's about how the SMGs perform.
This goes for literally all Allied SMGs.
You put an Axis SMG-wielding unit up against an Allied SMG-wielding unit at melee range, and the Allied SMGs ABSOLUTELY SHRED the Axis unit and instawipe the unit even if it starts retreating after one second of being fired upon.
Meanwhile, all Axis SMG units take half a year to wittle enemies down to half health and NEVER wipe ANYTHING unless they catch the unit on retreat with 10 health points and one model left.
You want historical accuracy and the originally intended game design that was supposed to make Conscripts incompetent but zergy? You switch the performance between Allied SMGs and Axis SMGs, so that the many-model Allied squads have to stand in close range of enemy units for a long time to deal serious damage, while the low-model Axis squads murder anyone who dares get into close range with them -- then it'll be accurate and balanced.
The bullshit is strong with this one.
I'll be brief here.
Axis SMG units are:
-weapon of 2nd cheapest unit in game and not even a combat unit, but a builder
-weapon of T0 call-in that does not require any upgrade
and
-early game weapon upgrade coming with a package with other goods, like rec acc bonus and nades, on a primarly long range infantry.
Allied SMGs are:
-literally ALL doctrinal
-most on elite infantry balanced to hardcounter squads at close range
-arrive no sooner then 10th minute, unless you coune meme AI partisans.
The two allied SMG units which are exception are:
-british REs, which arrive much later then any of axis SMG units.
-assault engies, which suck
