New Army "Caliber Configuration Study"

[stanc]

That would not alter the fact that a single cartridge replacing 5.56mm and 7.62mm in all infantry rifles, DMRs and LMGs in the company would still be a GPC as far as I'm concerned.

The original premise of the notional GPC was to replace all 5.56mm and 7.62mm weapons -- including GPMGs/MMGs -- in infantry units, thereby replacing a two-caliber system with a single caliber. That would have made "General Purpose Cartridge" an accurate description.

If 7.62 is replaced by .338 for GPMGs/MMGs, with other weapons using a different caliber, then the infantry would still have a two-caliber system. That makes the "GPC' something less than a GPC.
