Mr. Swapp,
You were discharged on 26APR17, so you will need to re-apply to join the unit.
If your application is accepted, you'll be PM'd all the required download links.
Remember that you have 30 days to complete a recruit class and then 45 days to complete AIT, but you can request an extension by contacting your CoC at any stage.
Any questions, let me know.
Respectfully Submitted,
CPL Hardman
Recruiting Office Detachment Personnel
