Address
In line with ZDv 10/8, the formal manner of addressing people with the rank Kapitänleutnant (OF-2) is "Herr/Frau Kapitänleutnant". However, in German tradition and in line with seamen's language, the title is abbreviated to "Herr/Frau Kaleu" in verbal communication (contemporary usage). Historically, in the Wehrmacht, the abbreviation spoken was "Herr Kaleun".
Rank and assignment
The United States Navy's rank of lieutenant is equal to Kapitänleutnant in NATO's military hierarchy (classed as OF-2). However German Navy Kapitänleutnant might be assigned to the so-called "line officer career" (de: Truppendienstlaufbahn or Truppendienstoffizier) or "officer specialist career" (de: Fachdienstlaufbahn or Fachdienstoffizier, officially: Offizier des militärfachlichen Dienstes).
Its rank insignia, worn on the sleeves and shoulders, are one golden five-pointed star above two golden stripes with one half stripes between them (without the star when rank loops are worn).
Line Officer career
A Kapitänleutnant (line officer) may command smaller ships (e.g. submarine class 206A, minehunter class 332) or serve as principal warfare officer on larger warships, giving the rank responsibilities more along those of a Lieutenant commander in the U.S. or Royal navies.
