Long range weapons in cover do nothing for soviets when they can be rifle nade spammed with no risk. What conscripts need is something to force the Germans out of cover at long range with no risk. Like a long range Molotov launcher. While Germans dodge the long range molotov you Oorah in to close the distance.
A long range lolotov launcher? That would be ridiculously funny.
How about giving cons a 50mm mortar? High RoF and distance similar to german rifle grenade??
I think that would be great if Relic brings in forgotten weapons like this one and F-1 grenade aka "limonka".
