would my cremated remains be at the same site as my husbandbands burried body?

Yes they could be. For the most accurate information, please contact ANC.

Yes - eligible dependents are interred or inurned with the service member.

Yes you can

As long as the spouse qualifies to be buried with their SO it doesn't matter if one is cremated.

I have friend whose parents are buried there like that.

I dont know. You would have to ask Arlington Cemetery for this question. Sorrt I couldn't hep you Betty.
