New Army "Caliber Configuration Study"

[stanc]

Caliber wont matter...

You said that in one fight, "My team alone expended 3200 Rounds in 8.5 hours..."

Doesn't that argue for the smallest, lightest cartridge feasible, so as to maximize the number of rounds carried?

...we need to add a LMG to the squad...

Since the infantry squad currently has two M249 LMG's, I presume you mean add one in a larger caliber? Doesn't that contradict your statement above?
