Dgarrett,
If it makes you feel any better, snipers average something around 1.3-1.7 rounds per kill, depending on where you get your figures from. Our SDMs are probably up there fairly high as well.
Some years back, some congressional weenie tried to get an investigation going concerning war crimes against (comitted by) our troops. The number of Al Qaeda and insurgent fighters that were turning up with single bullet wounds through the head was apparently disconcerting to some leftist hand-wringers over here, and they alleged that these constituted proof that our troops were executing prisoners. A little study confirmed that improved marksmanship training, combined with the advent of optics on most soldiers rifles (just try to find a recent pic of troops armed with iron-sighted rifles) meant that when they had an exposed target, they popped it. Just happened that that's what was visible to them, so that's what they shot.
As I saw it, they all got their 72 virgins, so everyone's happy . . . what's the problem?
