Today, an SFC from the PDA (Physical Disabilities Agency) called me. He emailed me a document (Election Relative to Re-Enlistment) on which I had to declare my intentions regarding active duty (this is separate from the one I signed for the medical board).
I initialed the “I elect to reenlist in the Regular Army/Army Reserve/National Guard within 90 days following approval of my PEB findings” box.
I was informed this document would be sent to a DoD civilian who would then contact me with further instructions regarding my “reenlistment” within the week. Below is the form I received.
