Did you sign your 199? those are your final ratings. are you perhaps TDRL on DOD side. or did you happen yo open another claim after you received your proposed ratings?
How did you get out of IDES without Finalized ratings? were u reserves or guard. or did MEB return you to duty and you ETS'd. Also what service were u in.
You should not be thinking 19 yrs of service. start thinking 20 yrs of service. submit a coad if you are in the meb. if not, drop your retirement packet.
So once Air evac submits your packet to MEDCOM, you will get an email once MEDCOM issues your report date. Air evac then contacts the SRU S1, that you are assigned and they are supposed to cut your orders on IPPSA.
