One solution would be to adjust the ranges to LMG: 30″, MMG: 36″ & HMG 42″. Having commanded a scout unit that had both MMG (M60) & HMG (M2 HB), I can tell you that the HMG’s longer effective range was very real and mattered. On the other hand, the developers often simplify things for game-play purposes – such as giving all rifles the same range. In reality the M1 carbine did not have near the effective range of the M1 rifle.
