Yeah, great solution. Ignore the obvious thing that the Soviet infantry is poorly designed. We do not have PPSh-41 to fight against the LMG infantry because "I decided so." We have an eternal pull between Conscripts and Penals. We have the eclipse of the Guard because the Penals have are PTRS. What the Soviets really need is a big and radical restructuring of the infantry, because it does not work correctly.
I have pointed out the problems of the Soviet infatry numerous times. What conscripts do not need is an LMG.
The reason they do not need an LMG is simple. If all mainline infatry get an LMGs none would move them and all the fight would at max range in cover.
Infantries where design to have an optimum range of fighting and thus create a dynamic where each player wants to fight in his optimum range. This is called "relative positioning" and making all mainline infantries able to equip with LMG nullifies the whole concept.
if the BAR not a machine gun, should it not drop? Or should the SMG and AR drop, because if the BAR is just an automatic rifle, its name is deciphered. Rifles must not drop.
Weapon type is decided by it "DPS profile" and BAR does not use an LMG profile. Being dropable or not is completely irrelevant.
