Most of the time you can simply contact the closest chapter of the VFW (Veterans of Foreign Wars) and they will handle arrangements. Just did this with my Aunt two weeks ago. I contacted the VFW, they contacted the Army and things went off without a hitch.

Matter of fact, we contacted the Chillocothe, Ohio branch and they arranged for honors at the cemetery where she was buried in Chesterland, five hours north of Chillicothe.
