here is a link to a picture of a vehicle mounted M240 machine gun.
And here is a link to it being carried by a soldier...
I'm not sure of your point
. Can you mount a LMG on a vehicle? Why yes you can. Does that make it the only purpose of said LMG? Why no it doesn't.
I will concede on the M249 though. for some reason I was getting it confused with the M2(which is also vehicle mounted).
Not sure how you confused the mother of all heavy machineguns that fires the awesome 50 cal with a squad automatic weapon that fires assault weapon caliber ammunition.
I say we just admit there was a misunderstanding, and go back to talking about the actual point of this thread.
