Feelings.

Just received this via email. I don't care if it's apocryphal, I like it:

While interviewing an anonymous Marine scout sniper on his sniper skills, a Reuters News agent asked him what he felt when shooting members of Al Qaeda in Afghanistan.

The Marine shrugged and replied, "Recoil."

Edited to add that appropriate image, thanks to Roger at Curmudgeonly & Skeptical.
