spent a year in iraq, shot at with everything from 5.56("friendly fire") to 109mm rocket.
never took a hit(from small arms), but a buddy handing me a bottle of water took one in his sapi plate. if he hadn't stepped right then it would have gotten me in the side.
we got ambushed by a bunch of army reservists once, luckily they really sucked, and only shot out a few tires.
also splattered with gasoline that they tried to jelly into foo gas. glad i didnt return fire then!
There is only one tactical principle which is not subject to change. It is to use the means at hand to inflict the maximum amount of wound, death, and destruction on the enemy in the minimum amount of time."
