I don't think so, I got the rating after I was discharged. It was backdated to my release from active duty. The trigger that was used was the letters written to the ARNG from my va psychiatrist and psychologist . They were requesting I get medically discharged from the ARNG and that I do not need to go to drills anymore. I was told not to go back to the unit, that the unit would handle all of the paperwork. I didn't sign anything nor was I ever told I needed to do a meb or peb. It was only after a few months that I was called and told I was discharged and was sent a ng-22. It looks like the ssmbr and state surgeon general used those letters as reason.
I feel your pain, as I am in the exact same boat. Was placed into retired reserve due to being medically unfit for prolonged PTSD. Orders dated 03 Jun 2011. Army stated non duty related. However, VA service connected it to my Iraq deployment 30% in Aug 2009. Va has sinced increased to 50% same condition. I filed with ABCMR in Oct 2011 still waiting on news. More details of my case can be seen on my post dated 6 May 2012. Hope thing work out for us brother, we have to fight for what we and our families deserve. GOOD LUCKwell, hopefully the ABCMR will intervene as I sent my "packet" to them.
