What does DD256 RE4 honorable discharge mean?
The DD256 is your honorable discharge certificate, which you can
display in a similar manner to a diploma or degree. The RE4 reentry
code means that you're not recommended for reenlistment - some
branches get more specific, and add a letter to the end of the
reentry code to give a more specific reason for the
characterization of service - some do not. The RE4 will more than
likely prevent you from being able to reenlist.
