yes, but that doesn't take into account that an HMG has a larger supply of ammo, and can fire continously much longer, then a lmg. And other features that make HMGs more of a threat and deadlier.

If that is not a factor into calculating the kill specs? what is taken into account? is it just caliber and ROF, like Mark said?

in response to, the MG-42 part. so the weapons where identical , except for their mountings (bipod,heavy tripod)?
