I know this sounds crazy.....

FO; That makes sense!

The weirdest combo I have seen is a WSS sgt wearing a U-boat badge!
But it makes sense as he was a Kriegsberichter and managed to go on a 3 month U-boat patrol for propaganda purposes for whaterver reason and was indeed awarded one by the U-boat commander!
Later pictures show this guy wearing this badge proudly on the eastern front!

Maybe handed out to him by the U-boat commander, but not awarded by the U-boat CO.

General Helmuth Weidling, the last commander of the Berlin garrison, seems to be wearing a U-Boat badge at the time of his surrender.
