New Army "Caliber Configuration Study"

[Michael]

And since when isn't the .338 LWMMG a portable machine gun?

All MGs are portable - even the M2 .50 and the Mk19. I think the question is what class it is in - light, medium or heavy and whether or not it's tactically feasible/a good idea to man pack it around; based on situation, terrain, ammo requirements, size of gun team etc. When you talk about light/medium/heavy weapons, the weight and bulk are considered more so than the caliber. I seem to remember Light Weight were less than about 25lbs total, Medium were 25ish to 45ish, and anything over about 45lbs was considered a Heavy weapon.

I would love to see a .338MG, but have my doubts it would be a 'medium' machine gun.
