Concur about the article. A very interesting overview of the history, skills, and psychology of a long-range shooter.
I thought the most interesting point in the article was almost a throwaway generalization: the assertion that a sniper's role in military operations is essentially defensive. I sure never got that feeling from any of Stephen Hunter's Bob Lee Swagger novels.
(Which is not a criticism. Hunter's books are novels, not how-to manuals. I like Hunter's books a lot, but don't regard them as totally realistic. But that discussion is for another day and another thread -- maybe even another forum.)
