So far I have only been able to find the equivalent of Schutze - Hauptfeldwebel for the Nachrichtentruppe or Funkdienst. Can anyone help?

I hope it helps:

I wasn't able to find out anything from those that I already know of
Most specifically I'm looking for Leutnant and above equivalent ranks for them
