New Army "Caliber Configuration Study"

[stanc]

...I would expect the LDAM MMG to be concentrated in support fire elements at platoon or company level, and assigned to squads for specific missions in which its very long range will be needed.

Yes, that's my view, too. Which is why I said it appears that infantry units would still have two calibers, thereby ruling out a single GPC.

As I said, I would expect CLAWS to be the ammo for standard infantry rifles, DMRs (probably) and bipod-mounted LMGs...

I agree. IMO, the question then is if CLAWS ammo needs to have the same level of performance envisioned for the notional GPC, or would a lighter weight cartridge of somewhat lesser performance be a better choice for the CLAWS/LDAM concept?
