That's where I'm conflicted, really. I have read the study--and to me, it highlights the need for training. I'd rather carry the weight of one 7.62 round that hits target area, rather than five 5.56 rounds that don't, y'know?
To be honest, I haven't made up my mind yet. Reading all the PR flak for the XM-8, it sounded great... all the good bits of an M4, but lighter (except for that giant goofy handle). But digging a little deeper, I have my doubts.
Like I said, I'm still in the air on it. I like NDD's solution, but I'm afraid it would require more training than our leadership is currently willing to give our troops.
