Carlos Hathcock was probably one of the most well known snipers in American military history no matter what branch you're in. If you're in the shooting club, you've heard of him. His book is one of my top books about Vietnam from the individual experience. He did lose my respect when he went and did some bullshit story about how "impossible" the JFK assassination shooting was and how Lee Harvey Oswald couldn't have made those basic shots. It's just such bullshit. Even a basic bitch Marine with a pizzabox can hit a human sized target at under 100 yards.
