Absolutely not! Because what if you have a gun, then during that time you get all pissy and throw a fit..next thing you know youd be shooting our troops. Im going to be honest talk to a Recruiter ask questions, if he asks you if you have ANY medical problems, dont you dare lie. you tell go on and tell him or her you are bipolar and ask him if it is possible to join. on some cases theyll let you join and some not. Good Luck Dude !
