I think the amount of discrimination may partially depend on your location. As a military retiree, I've had no problems with medical treatment or administrative issues at either NAS Whidbey Is or the naval station in Everett Washington. I've talked to others here who have told me the care they've received at the Seattle VA facility has been absolutely fabulous.
