Someone needs more range time.

Someone needs more range time.
You could go to the range everyday of the year and hit everything you are aiming at and still when the time comes to actually engage someone you miss.
Why? Simple, at the range you are not in danger.
Ask any infantryman just how well they did during their first fire fight and most (if honest) will admit not doing so well.
You are only going to do well once you get experience facing someone trying to kill you although it never gets easy killing someone (and the burden of doing so remains with you the rest of your life).
