From this site, a little old, I admit,
16. Where can I find German military records?
are addresses to which one can apply for records for German military personnel.
" World War II German military personnel may have service records at
Bundesarchiv - Zentralnachweisstelle
Abteigarten 6
52076 Aachen
<HTTP: standorte.php www.bundesarchiv.de>
or at
Deutsche Dienststelle (WASt)
Eichborndamm 179
13403 Berlin
<

WASt holdings center on those reported to be prisoners of war
(POW), missing in action (MIA), or killed in action (KIA), and
also on members of the navy, though other records are also held.
The Bundesarchiv has no records for navy personnel. Requests
for information may be sent to either office; they will be
forwarded as needed to the appropriate office."
As far as I am aware, no acknowledgement would be sent out on receipt of the application and that this may take a long while to process.
