New Army "Caliber Configuration Study"

[Michael]

If a .338 MMG weighs no more than a 7.62 MMG, I would expect it to be carried on foot-mobile operations just as the 7.62 MMG currently is. (Although that could change, depending on performance of the squad cartridge.)

Stan - I think this is a poor assumption as the ammo will weigh twice as much as the 7.62 ammo.
