my best advice to you is to NOT take a Snipe job which would actually just be infantry if im not mistaken, id take a MOS that will benifit your civilian life
but that is just my opinion
if you wanted to know more, i would talk to a friend you know in your area who has a recruiter and then set up a lunch with that recruter and have a note pad full of questions you would like to ask about his branch and others as well
but if you want sniper i would look more into USMC
then agian i am a newbie trying to give you the best advice aAND AND AND if your serious about it.. let me know so i can G-RAP you and give you a grand (;
