New Army "Caliber Configuration Study"

[nincomp]

The GPC idea seems to be an LMG that could perform in the same capacity as the current MMG where the dismounted Grunt is concerned.

The general idea is that the GPC would have the effective range of the 7.62x51 MMG and replace the 7.62x51 MMG for the dismounted "Grunt." The GPC ammo would be lighter than linked 7.62x51 per round and (hopefully) be used in lighter LMGs.

The GPC would also be used to extend the reach of a soldier's individual weapon to permit effective fire at longer ranges. This would also permit more effective suppressive fire, permitting the LMG to maneuver, among other things.

Part of the genesis of the GPC stems from the experience of Afghanistan*, where many engagements occur beyond the effective range of the 5.56. One veteran said that everyone except the MMG gunner and maybe a Designated Marksman could only twiddle their thumbs. Even in locations where our troops could easily maneuver close enough to effectively use their rifles, the attackers would have had enough time pack up and leave.

Tony has written an interesting paper which is much more detailed than my summary.

* Many of the unstable parts of the world, especially in the Middle East, have terrain where long-range fire would be expected.
