Today, I recieved a Supplemental Statement of the Case from my VA regional Office, indicating denial of a S/C for PTSD. They state that the USASCURR (United States Armed Services Center for Unit Records Research) has no evidence of the stressors. Eventhough, the RO states in it's SSOC that "although incidents that the veteran provided may be true, but they are not researchable". All the evidence I've submitted, ie. letters from military members that have knowledge of the incident, my VA Mental Hyg. Dr. confims Chronic PTSD condition, VA C&P Dr. also confirmed the PTSD condition (Chronic) during a C&P evaluation. What do I do? The RO has given me 60 days to reply. Should I keep on debating with these a....oles local or go to the BVA.
