How far we are being engaged had nothing to do with my post, I was simply saying none of our "enemies" carry 7.62x51. And if our troops run out of ammo using enemy ammo is not a viable option. That's all I was speaking to. I served my time in Afghanistan and was a designated marksmen. Not saying that means I know everything the army does etc, and not saying that qualifies me as better than anyone. But I very well understand enemy engagement at distances that a 223 and 308 are not the absolute best for the job.
