I have no idea what issues caused your discharge. A "bad conduct" discharge under less than honorable conditions would probably eliminate any possible enlistment into the Coast Guard. As I mentioned earlier, the CG is probably the most selective of all 5 branches. Right now, thousands of fully qualified applicants are waiting for their chance to join, so I would venture that you have very little if any chance on enlistment. One of the recruiters will be along to chime in on this issue, but I'm afraid your prospects are bleak.
