Look, if u wanna be up front you go Marine. the way the military works is the marines usually clear the general path and the army follows up to clear the spot. you can join the AF but honestly unless u went to the academy your likely only to be a mechinac. the Navy/Coast Guard have the easiest jobs right about now. And the Marines are slightly better trained. but the army is G too. i personally prefer marine corps. because my uncles and cousins were/are in it and im joining up wen i turn 18.
