NO, what I'm saying is he can receive both railroad retirement and social security in addition to va disability. I've only been receiving railroad retirement and VA disability for the last 2 years.
When I was talking about railroad retirement and social security together I got completely off subject. Since 1984, individuals can't receive both railroad retirement and social security. The WWII vet probably retired before 1984 and can receive both railroad retirement and social security, because he was grandfathered under the old law.
But I think this all applies only if he is service connected, not attempting to get non-service connected VA pension.
