Carlos Hathcock

During Vietnam War American sniper Carlos Hathcock volunteered to crawl for 3 days across 2000m of the open field containing an enemy headquarters. He had bed sores from staying motionless for so long. He could only move when the wind blew the grass around him. Enemy patrols came so close that they actually stepped on his knuckles and stopped to smoke within feet of him. He took a single shot that killed an NVA General and he then had to backtrack the same way while enemy patrols were swarming looking for a sniper. He was only able to move inches at a time and made it back without being spotted.
