As I recall, recruits are taught marksmanship and don’t become Marines unless they meet the Corps’ minimum standards.
True. I reacted to Happy Rain's response to:

which is true. Most people can be taught marksmanship if taught properly and practiced.
You don't have to be sniper trained to hit a man at a couple of hundred yards with a rifle.
