So we have seen how the crew addresses the Captain in this question; but how about the Chief? At about 3:03:00, Lt. Werner asks the Chief, Kommen wir je wieder hoch, LI? and calls him ...
In the movie Das Boot, the crew address the captain with a word I don't understand. I think it may be "Kaleun", which I assume is short for "Kapitan Leutnant". Am I right? Is that a real word?
