Third Generation Battle Rifle

[stanc]

The only sensible small arms weapon system for an organization that refuses to allow talented and qualified officers to write doctrine is to reduce the weight of current systems, without sacrificing capability. A new standard service rifle/carbine won't do that, especially not in a larger caliber.

A new LMG that can displace some of the 7.62 belt-fed weapons with a lighter ammunition footprint would benefit even the worst offenders, no matter how illogical the chain of command and leadership climate was...

In short, we need a 3rd Generation LMG if anything...

I'm inclined to agree with all that. I just think it's unlikely that a new caliber for an LMG can be adopted without also chambering the standard rifle/carbine in the same caliber.
