In the German Bundeswehr, officers of the rank of Major, Oberstleutnant and Oberst in the Heer (army) and Luftwaffe (air force), and Korvettenkapitän, Fregattenkapitän and Kapitän zur See in the German Navy are traditionally known as Stabsoffiziere (English: staff officers).
A number of other armed forces in the Commonwealth, including Australia and New Zealand, also follow this pattern.
This officer group in the United States Armed Forces has two different names depending on the branch.
