Nathan, I have been in combat, it matters. Everything matters when you are fighting for your life. Having more range, accuracy and lethality is extremely important.
As Colonel Hal Moore said after the battle of the Idrang Valley, the M-16 made the difference. It was a wonderful weapon, his words. Do what you want with your life. I really don't care much what other people like but I am firmly against wrong remarks.
An Ak is just as good at firing for effect at short range but that's all. Battles the world over for 50 years have shown the M-16 the dominate and superior fighting rifle regardless of what hillbillies think. In part to it's far greater range and accuracy.
