[1] There was no counterpart in the German Heer and Luftwaffe, but Kommodore would have been comparable to Oberführer in the Waffen-SS.
This was most common with U-boat commanders in charge of several submarines that were assigned to a single task force.
By World War II, Kommodore had at last become an actual - though rarely used - rank in the Kriegsmarine.
The position was considered that of a senior captain, with insignia being the shoulder boards of a Kapitän zur See with one thick admiral's rank stripe (52 mm) on the sleeve.
Shoulder straps, corresponding to those of Kapitän zur See, had to be worn on uniform jackets and consisted of twisted silver braids with two gold pips (stars) on padding in navy blue Waffenfarbe.
