I need some help here. The rules for Weapon Mounts specify that Normal ones can hold weapons up to the size of an LMG, and that Reinforced ones can carry the bigger ones.
I cannot for the life of me find any tables or anything regarding the relative sizes of any weapons, let alone LMGs in particular. I could improvise for some things, but several of the weapon descriptions are sufficiently vague that an argument could be made either way.
