It does not take a real combat Infantryman to pull the trigger from 2000 yards. Pull the trigger from 10 yards in and you might know what it feels like to kill someone.
1: Have you ever been in either of those situations? If not, then STHU.
2: In every account of snipers I've ever read, there is real emotion involved in the aftermath of taking the life on another human life. Certainly, that emotion is tempered by the knowledge that the poor b-stard on the receiving end of a trigger pull deserved his fate, but that only lessens the emotional toll it takes, not removes it.
3: Snipers are as much in danger every minute they're out there as any infantryman - maybe even more, because enemy combatants target them specifically, largely because of the havoc they can wreak on them.
Wouldn’t a scope make things real close and sometimes you have to watch the enemy for days. That is kinda personal. Being face to face is also personal. Being on the other side of the world and hearing your son’s best friend who you never met has been killed is personal.
