tier 2

My tier review was successful and they have sent the paperwork which I have returned. Does anyone know how long it takes for them to process this is it day, weeks, months???? I’ve tried to call but it just says they aren’t answering the phones in that department and the call ends.

I have recently received notification I am getting medical discharged as tier 2 with PTSD can anybody help with information as to what this means and what I need to do next? Thanks
