I did a total of 21 and half years between active army and national guard. Went through the PEB board and initially found not fit for duty with a 40 percent disability rating putting me on TDRL. At the end of the five years, I had my first re-evaluation and was found to only have 20 percent disability after having two back surgeries. I appealed the decision and lost. They separated me with severance pay instead of transferring me to the National Guard retirement. They bought back my 7 active duty years and left me with 14 and half years of National Guard military service. The National Guard discharged me in the beginning of my TDRL and placed me into retirement. I just checked my IPERMS and it doesn't show any of my PEB OR MEB paperwork. It shows me as retired. No one can tell me if I'm still able to apply for retirement benefits at age 60.
