Gruppenkommandeur is a Luftwaffe position (not rank),[1] that is the equivalent of a commander of a group or wing in other air forces.
A Gruppenkommandeur usually has the rank of Major or Oberstleutnant (Lieutenant Colonel), and commands a Gruppe, which is a sub-unit of a Geschwader.
A Gruppe usually consists of three or four Staffeln (each of which is commanded by a Staffelkapitän).
