So, in criticizing the performance of the M4 carbine in Afghanistan, one Major General Robert Scales, Jr. USA (Ret.) suggested reviving the dormant XM8 program.
The XM8 is, of course, another carbine in 5.56 NATO.
The fact that a man so obviously ignorant of the simplest elements of riflery managed to become a Major General in the Army of my nation makes me very sad inside.
(The alternative explanation, of course, is that the "You Suck And We Hate You" company has him on retainer, but I'd prefer to think that the retired O-8 is an idiot, rather than a crook and a shill.)
As I said at Unc's, the military needs to lose its obsession with some imaginary bygone day of riflery, when every draftee could pick up his (M1873/Krag/Springfield/Garand/M-14/20″ M-16) and accurately engage point targets at mortar ranges.
