Not trying to belittle Clark's post, but I thought it wasn't what you wanted. When/if you talk to recruiters, SPECIFY you are talking about HAND HELD ARMS, go ahead and say 50 cal on down. Anything larger than that MIGHT get you in artillery. Also ask if they have GUARANTEED jobs in the field you are interested in. If they don't you might want to go ahead and take your chances with that branch of the service or move on to another branch. DO YOUR RESEARCH!!!
