Each batch of Naval cadets, referred to as crews, chose their own emblem when joining the Kriegsmarine. Here below are the emblems we know of, some are not ready yet but we'll put them in here as time goes by.
One of the most famous is of course the Olympic Rings of Crew 36 (read more about it here). The emblems were then often placed on U-boats commanded by officers of those crews.
