You read a paragraph off to the doctor at meps and he decides. I probably couldn't do a job like counter intel because if I stutter that shit could get me killed. But I didn't have any job restrictions joining because mine isn't so bad. But there's plenty of officers and higher ranking personnel who stutter. I met an e-9 who stuttered, my platoon Sgt (e-6) in ait had a stutter and I met a captain who stuttered.
