I will try to advise you regarding your query, and I think others in the know will probably echo what I say.

German WW2 military service records were held at one time in a records section in Aachen/Kornelimunster. These were then transferred to a central archive in Berlin, the Deutsche Dienststelle (WASt), in Eichborndamm 61. At one time, such service records were available to researchers/authors, but in more recent times it has become more difficult to obtain details, since in the normal course of events such details would only be released to next-of-kin/relatives.

So, doing the kind of research that you are seeking to do today is far more difficult than 20-30 years ago.

Sorry for being the bearer of potential bad news, but that's the way it is today.
