I'm about to embark on a similar journey. Case management initiated the day after my 20-year mark. Only 7 years AFS out of 20 total for me, the rest in the ARNG, and sitting at 90% VBA rating. Case manager's already thinking medical retirement is the likely outcome, but I still need to go through the process.
The note I've read at
Defense Finance and Accounting Service > RetiredMilitary > disability > crdp (that's just beneath what
@RonG bolded in the first reply) makes me leery that I'd be able to draw retirement immediately, but the consensus here is that I actually would be under Chapter 61 after a PEB with CRDP?
What I could find using
@JoelPettit's source has a note: "A retired reserve member, retired under the provisions of 10 U.S.C., Chapter 61, is entitled to CRSC." under paragraph 8.5.2. "Reductions for Periods On or After January 1, 2013." I couldn't find a reference to CRDP in this instance though.
Sorry if I'm retreading already-answered content, I'm just looking for something more concrete than the note on the DFAS page that states "Reserve/Guard members who are retired under Chapter 61 for disability should contact their Branch of Service to determine their eligibility age." Thanks.
