German officers were not permitted to be a member of any political organization.
Sorry, Obio, I don't want to start a political discussion here, but I think I have to answer on this statement:
The membership in the NSDAP in fact was set in abeyance during an officer's active duty in the Wehrmacht.
Being a NSDAP member was definately no impediment for an officer's appointment! But of course, membership could speed up an officer's career...
It's true that membership in the NSDAP was not required for an officer, but from 1934 on, an officer's candidate was obliged to proof his
"aryan" origin.
It's also true that the Nazi party tried to increase its influence on the Wehrmacht and these efforts were less successful concerning the Luftwaffe (and the Marine too...), compared to the Heer. On December 22nd, 1943 the function of a
Nationalsozialistischer Führungsoffizier (=ideological education officer), who
had to be a party member, was installed (source:
"Die Wehrmacht" by Rolf-Dieter Müller http://books.google.de/books?id=tOBQq0HA7dYC ). In the end of 1944, there were about 48.000 of those active.
For reasons of historical accuracy, this clarification had to be made.

Markus.
