When stats show that OKW/SOV and OST/SOV are nearly equal in win rates and only USF and UKF are lacking, it is not logical to search for the solution in OKW. Touching Volks would upset the delicate balance with SOV. Instead, UKF and USF infantry should be slightly buffed.

I think it should be noted that infantry sections are beastly in the early game though, but seem to not scale super well anymore. Riflemen seem to be almost the other way around, with a bit weak early game and very good (but very muni intensive) late game scaling possibility.
It should also be noted that while rifles scale great with double BARs, they also have to spend by far the most munitions exclusively on infantry-carried anti-infantry weapon upgrades out of any faction. Volks only need to spend 60 per squad for about 3 squads, IS only need to spend 90 for 2-3 (or even more variance depending on particular army compositions) squads, soviets don’t need to spend any unless they go cons ppshs or guards (in which case 60 or 75 muni per squad for 3ish or 1-2 squads respectively), grens have to spend 60 or 45 depending on lmg42s or g43s for 2-3 (maybe 4) squads. Then you have riflemen, who need to eventually spend 120 muni on BARs for 3-4 squads (depending on how many rifles you make and whether you go captain or lieutenant). USF is also the only faction that has no infantry, call-in or normal, that don’t need muni upgrades to be at maximum potential against infantry (in contrast to, for example, pgrens, commandos, shocks, or falls). That’s one of my largest pet peeves wth the faction in general.
