This discussion reminds me of a scene in the great HBO serie Generation Kill. When you get shot at by a sniper, get out of sight! Zigzagging takes more time, thus gives the sniper more opportunities to hit you. If you hear bullets flying, get behind cover and keep your head down. If you move through an open space, run as fast as you can. And since an image says more than a thousand words: http://www.youtube.com/watch?v=bdaQHTWT_ZI edit: typo's
