New Army "Caliber Configuration Study"

[stanc]

It seems to me that if the Infantry has a 6.5mm LMG with a high BC projectile there will be no need to drag along the .338 MMG or any other MMG for that matter.

Quite possibly true. It sorta depends on the exact capabilities of the 6.5mm LMG, and mission requirements.

While the 50 cal can be deployed by dismounted squads, it's in no way practical, so why should we expect a .338 MMG to be implemented in this manner.

Because a .338 MMG would presumably be much, much lighter than a .50 HMG.
