The Designated Marksman comment is so true. I was the corpsman picked to go out with the dm's and snipers because I was prior service Marine Corps and had an infantry background in the national guard. The first meeting we had discussing missions and objectives, the school trained SSgt. walked in and the first thing he said to those dm's was, " let's get this straight right from the get go. Y'all are not snipers you are dm's!"
