Something I have noticed in my 50 years in the halls. The VA is not the same each generation because shoes are filled and rely on that. New feet in old shoes. The Rating system changes although shouldn't.

Same for Claims..PTSD the number one Complaint now as opposed to actual wounds of war..meaning scarring. PTSD takes time to assess, difficult, to actually answer with any positive result for the Veteran. Some cases severe, some less? This takes time and experts in the field. Recently I think actual Healthcare is terrific, Compensation more difficult.
Good Luck
