Game-wise, it might be worth noticing that the MG34/42 MMG units have three men per gun, while the HMG equivalents have four - making them slightly more survivable.

Rather off-topic: while the classification of a gun as LMG, MMG or HMG in SP games does not really affect the performance of the gun (which is defined by the actual stats), in the miniature wargaming environment there are sometimes strange debates about the classification of weapons into various categories - usually as a result of game designers who want to simplify game design by having only a few generic weapon categories, rather than individual statistics for each gun.
