I had the privilege of meeting a Vietnam War Era sniper at a local angel a couple of years ago. From looking at his target, yeah, he still had the touch. He and his spotter used to sign their casings and leave them behind as psy-ops. Said there was a no-excrement bounty on their heads.
I met a guy once who said his uncle was number two behind Hathcock in Vietnam.
If true, very special kind of hero.
