New Army "Caliber Configuration Study"

[Tony Williams]

So, since the 7.62 MMG is being used routinely, and not being restricted to specialized missions, why should we think it would necessarily be any different if the 7.62 MMG is replaced by a .338 MMG?

It wouldn't be different if the 5.56mm remains the standard infantry weapon calibre. It would be different if the 5.56mm were replaced by a GPC. The only reason that 7.62mm weapons are carried by dismounted squads now is because of the inadequate range of 5.56mm. A GPC capable of matching the long-range ballistics of the 7.62mm would mean that 7.62mm weapons would no longer need to be carried - so why should .338 be, in normal circumstances?
