What range?
What cover?
Who approached who?
What was the vet?
I can do tests showing infantry sections losing to osttruppen you know.
If there is no actual evidence of the test, I assume it was made the same way the tests of smoking companies proving that cigarettes are not responsible for cancer but in fact cure it.
Ahhh
Range: Point blank - (Medium range is nearly auto win for conscripts from what I know since 3 rifle still out does 5 MP40s)
Cover: Nil - CQB test, where both PPSH cons and MP40 volks SHOULD excel
Vet: 0
Didnt try who approaches who, but will do next time.
In most circumstances, the PPSH cons will win out against MP-40 Volks, while having similar, if not better utility in the form of sprint, cons repair kit (if using advanced war or cons support doc), hit the dirt suppression immunity.
Both have snare, volks have smoke but loses the rather effective flame nade for a "normal" grenade of questionable effectiveness. Molotov have the retarded dance of the motherland but it is also 20 muni only, so make of it what you will.
Both upgrades are bound by cmdr choices.
