Military snipers were trained sharpshooters assigned to kill a man with one perfect shot. These highly disciplined marksman often stalked a target for days waiting for just the right moment to squeeze the trigger. Lurking in the shadows alone, the deadly stealth of the sniper made him the most feared man on the battlefield. As a young hunter, Chuck Mawhinney grew up with a gun in his hand. In October 1967, Mawhinney was just 19 years old when he made his first kill as a scout sniper in Vietnam.
