I was discharged with an RE-3B after a divorce. Could I go Reserves or active again (or can I have my discharge code changed)?

RE-3B Individuals who have time lost during their last period of service. Ineligible for enlistment unless a waiver is granted. (paras 2-7 and 2-8a). Applicable to EM who have time lost during their last period of service.
Commonly that means AWOL, or dissertation, civilian jail without knowledge of unit so they can update SM status.

RE-3B is waiverable ...
But Id be hard pressed to approve a waiver for such conduct listed above. If it was some other reason, then perhaps...
..
The Services are cutting back ....getting rid of less then steller SM's.. Thus , cutting a waiver for someone that has lost time is stretch id think.

This should be an excellent place to get some information and insights into how to deal with your situation and answer your questions. Don't hesitate to private message some of those below if you feel comfortable in doing so, to give them more details into your unique circumstances. There is always a lot of 'back story' which will affect how your question is answered. Good luck.

I have been trying to get back in for almost 17 years now (eligible until i hit 42 per the MO Air Guard). At this point, I have to get a waiver, in order to go to MEPS to see if I can get a waiver.
It is most definitely a battle. Have your ducks in a row & make sure all "I"s are dotted & "T"s crossed. Also, it is important to have a dedicated recruiter. I went 16 years before I found a recruiter willing to go to bat all the way for me. In a little over a month, she was able to tell me more about my case than 4 other recruiters before her (of course, she also out-ranks the others, too...lol)
