You can dm me but it's based on how severe we are talking. Every branch goes through the same initial medical process called MEPS. From what I know from other people they may give you a reading test. If you can read the passage with minimal stutter then you're good to go. When I personally went to MEPs stuttering wasn't much of an issue. No one knew I stuttered. I'd focus more on getting a good asvab score. Everyone thought I was a genius for scoring a 92. It may help recruiters work more with you. Seriously I was getting handshake from people I didn't even know. It was weird af.
