I would like to obtain military records for my great-uncle Sigmund Haas. I was told he served in the Austrian Army on the Italian front during WWI. He was born 1891 and died 04 Oct 1918. I attached a burial record from Wiener Zentralfriedhof cemetery. The burial record contains the comments "Occupation: Feldwebel d.k.k. Reg. 36 Zug k.k. Reg. 136 Died In: 1160, Radetzkykaserne Tomb: No Urn: NoComments: Mannschaftsgrab". Can the comments help with finding his military records?
