Hows it going GM2,
How much time you got left on your contract? If your chain of command is willing to let you go then the process is easy. Mine was a little difficult because I was coming from the IW community. As seen on this thread, your first step is to start process of getting a DD368 routed up your chain of command. Hopefully you are in good standing with them and they know you been wanting to do this. You will also need to talk to an Army recruiter. They will get you in the Army once NAVPERS receives your DD368 conditional release and approves for you to leave. Look at my previous posts. I lay out a step by step way to do it. Just omit the parts that pertain to IW rates (region and headquarters approval). As far as rank reduction goes I kept my rank but that is decided by the Army. Your recruiter will send in a package for a decision to be made. Don't know what really determines the outcome, but be sure to send every award and qual you got. Petty officer indoc certs as well.
As far as 11b opt 40 goes, from popular posts and from talking to many priors who have attempted, they really don't have those options available for us prior service members at the recruiters office or MEPS. Getting an 11b contract, then at basic getting hold of a RASP recruiter or waiting til they show up at your company at boot might be your best choice. This is a gamble. Everything is a gamble for people trying to get that opt40 at this time. As of lately it seems the young straight out of high school kids are getting those. But try and push for it when talking to the recruiter. If you get it you'll be the first out of many priors I know trying to land that
