I'll have to agree to disagree with you on a number of points.
I would invite you to post those opinions on Ar15.com or M4carbine.net.
There are folks there that have been there and done it that can give you much better info than I can on how they feel about the 5.56 in combat.
I don't have the time or inclination to debate this. This debate has been going on for many years now and my input isn't going to make a difference.
