4 Photos of Odd Luft Insignia

[CampX]

Here are 4 more photos of Luft Personnal wearing odd Collar Badges.
Can anyone tell me what the insignia stands for?
One of the photos has a Luft Fellow with black backed collars, I have not seen this before

Nothing unusual there, really.

Black collar patches were worn by the Luftwaffe's construction branch, which eventually also included the air raid-protection units.

The other men (with the triangular rank "stars" on their collar patches) are Beamte (officials) of the Luftwaffe.

Thank you, what about the Officer with the collars that have leaves going almost all the way around?

Hi Dean, Andreas has it covered (as per usual!). If you look close at the pic, he is another official. The tab you asked about is illustrated here in this rank chart. Please take a look:

Cheers, Ade.

The guy in the first photo may be flak/artillery, his collar tabs would be red which appear to be quite dark in black/white photos!...
