Grendel LMG

The article's points are largely an echo of the Marine Auto Rifle argument points. And there is strong suspicion in some ranks that the Marine Auto Rifle case was just a back door to get the HK into mainstream inventory ("Does it make sense to have both the M4 and the M27? They are so close. let's just simplify").

I do wish this bit of historical revisionism could be killed off. The M27 was not adopted as a backdoor replacement for the M4.
It was impossible, because the M27 was adopted five years before the M4 became the primary individual weapon for infantry.
