Thank you for trusting your question to JA today. I am a licensed attorney with over a decade of law practice and over 20 years of experience in the legal field. I’m happy to be of assistance.
Chapter 5 contains numerous different reasons for a separation, acting as a sort of catch all chapter. So, just knowing the Chapter 5 number doesn't give sufficient information to know if you'd be able to reenlist.
What matters is not the Chapter number, but rather, the Reenlist Code or RE code which would be contained on your NGB 22 form, which is the National Guard version of a DD Form 214. An RE code is an indication to all of the branches about your ability to reenlist.
An RE-1 or RE-2 generally allows for reenlistment if you meet the qualification requirements. An RE-4 is a bar to rejoining at all.
An RE-3 technically allows for rejoining with the receipt of a waiver, but right now an RE-3 is essentially the same as an RE-4 because waivers aren't being offered right now. There are too many people vying for too few jobs, though the National Guard has a little more wiggle room on this issue.
