Indeed, plenty of opportunity for confusion. My wife first told me that her father was in the SS and it transpired that he was in the SA; being a civil servant (beamter) he had been pretty much given no choice but to join up. Mercifully he was taken POW in North Africa and had a fairly civilised war in the UK and Canada. Of course there were no SS in North Africa either; I believe at the specific stipulation of Rommel.
I'm looking forward to the updates on this one.
