Luft Flak Abteilung commander rank?

[Joda]

Which was the rank for a Luft Flak Abteilung commander?

Was an Oberleutnant a Batterie commander?

If so, what was the role of a Leutnant?

Many thanks in advance

A Flak Abteilung Kdr. was often Major or Hauptmann. A Batterie Chef was often Oberleutnant or even Hauptmann, in particulary in big Abteilung.
