Is my nephew entitled to military benefits?

My nephew is 12 years old and has asbergers syndrome. When he was 5 years old my sister in law took his father to court for a DNA test. He is the father but in court told the judge that he is willing to pay child support but chooses not to be in the boys life. when he was 8 he was diagnosed with asbergers. She has tried to get help and therapy for him but according to the state of VA she makes too much money-she makes 24 thousand a year before taxes. She applied for SSI but because he is an A B student they said that it was not considered a hinderance. Accademically he is a good student but socially he is very awkward, does not interact with his peers and is obsessed with school busses. He has every symptom and profile of asbergers and it is so sad to see him non interact and close himself off when he is around other children. because his father is retired army, is he entitled to any army medical benefits?

I accompanied her to court last week and she pleaded with The department of Social Security and said "If approved for SSI I don't want the money, don't send the check to me, send it to the program and therapy center-so long as he gets help!" it was so sad seeing her like that. I think everyone was crying.

please no nasty comments. just need advice.
