Sorry guys, had a...lets call it "moment" there.
Back to the uniforms. If you are locked up in a tin can for over a month or more with 50+ men...I think wearing a tie and uniform jacket becomes a pretty distant memory.
If you read "Das Boot" from
Lothar-Günther Buchheim (sure you have), there is a scene when the boat bunkers in Vigo. The Captain on the "milk cow" makes a mistake and welcomes the "Eins WO" (First Officer) as the U-Boat Captain, because "Der Alte" (the old man) looks so scruffy in hes old worn out sweater..."like a beggar" Buchheim writes.
Some pic of the guys:
This pic I would say is more of a posing shot, or maybe the boat was at port. You rarely see Officers wearing ties
in any photos or films from the period.
Also check the interior in the game, there are A LOT of fans everywhere, you can see one in the 2nd pic. I think they where there for a reason
On this subject i have done a "US NAVY OFFICER HAT" and added "RANKS INSIGNIA" to the officers collars here:
