My number 2 son just graduated from Marine Bootcamp last week, he had a hell of a time qualifying, and came close to washing out completely over marksmanship. Why? His "highly trained, knowledgable" instructors completely missed his cross dominance (left handed, right eyed). He's never had my interests in shooting and weaponry, so he wasn't aware of the problem. He had an excuse, but his so called expert instructors have none, IMO.I couldn't believe in a service brach that prides itself on riflery and individual marksmanship skills the instructors could be so ignorant.
