Brotha, go for it. If they deem it unsafe they won't let you in. You just read a paragraph and if you stutter more than a certain number of times ( idk how many, but it's pretty high) then they won't let you in. If anything it'll be a medical discharge as long as youre up front with them. If you lie about it, get it in, then they find out about it they can do legal shit. Be honest. I've known a handful of high ranked people who stuttered. They're all confident about it and don't let it hold them back. Don't get me wrong. You WILL get shit for it. So be on top of your shit at work and be the best God damn soldier out there. Cause if not you'll get shit on. Improving will come if your conscious about it but dont dwell on it. Being more comfortable in my own skin helped me.
