I'm listening to the HowStuffWorks podcast on "How Military Snipers Work" interesting stuff. Check out the article...
http://science.howstuffworks.com/sniper.htmFor most of us, the word "sniper" evokes some unsettling imagery -- a lone gunman, undetectable, on the hunt. And while military snipers are indeed elite shooters who hide, line up a target in their sights and pull the trigger, there is a lot more to it than that.
When a sniper takes a shot, there are countless variables to consider before squeezing the trigger --- wind speed, wind direction, range, target movement, mirage, light source, temperature, barometric pressure, and that's just the beginning. The work that goes into getting a good position to take a shot is immense. That's why snipers always work in pairs. Surprised? Most people are.
