Or military "experts".
A) The fact that this raging douche-nozzle was a Lieutenant General in the US Army explains quite a bit about the problems the Army is currently facing.
B) The AR-15 was never used by the US military in any capacity.
C) There is no such thing as "full semi-auto".
And in my opinion, as well as many other military members, the 5.56mm round is under-powered, weak, ineffective, and pathetic. There are reasons people have been calling for a bigger round ever since I knew what ballistics were, and that's *mumblemumble* decades now. The experiences in Iraq and Afghanistan have not made those calls any softer.
In short, this general got used by CNN like a condom, and he's worth just about as much as a used prophylactic after everything is said and done.
