what about bringing some new german infantry weapons to the game like the Fallschirmjägergewehr 42 (FG 42) for exemple ???
i noticed on many maps, that some allied infantry waepons are way too strong, especiallay the russian PPSh submachinegun (a 7,62mmx25 doing much more damage than 9mm parabellum). the mp 38 and 40 was a good submachine gun, slightly not as good as the PPSh, but against that gun there is nearly no chance for german infantry on the early war maps. in my opinion not everything has to be exactly balanced for playability but the PPSh is something like an Übergun in FH 0.61 (i think it's nearly as precise fired while running as a light german machingegun fired gone prone). I think the other guns are ok, even the better us carabines (you still have a chance against them).
i think there are 2 ways:
1. weaken the russian PPSh a little bit or
2. give the germans a new weapon on some of the german vs soviet maps.
for example the Fallschirmjägergewehr 42

7.62x57 mm 800rpm and 751m/s muzzle velocity
it's an airborne assault rifle which could also be used as a light machinegun (and with that x57 (lenth of the shell -> propellant) there is a reason for some amount of damage, compared with the x25 and the way too high damage of the PPSh)
