Anyone have a good suggestion on how/where to research a relative's military records? Something that won't cost a fortune.

I'd like to find out some details about my long deceased Uncle Ralph, and there's nobody left to ask. He was in the Army in WWII, I think I was told once he was in the Rangers, not sure. I know he saw some heavy action. I Googled his name, found his obituary, and found out he was awarded a Bronze Star and a Silver Star, so now I'm itching for details.

All I really know for sure is that whatever he went through turned him into the most severe alcoholic I've ever known, so it must have been heavy.
