Numbers... what are they called?

This picture is a good example of what I mean.

Do you see the numbers on the side? "K5DH"? What are they called, and if anyone happens to know what the British called those numbers, if they had a different name for them, that would be extremely helpful. But if not, I still need to know a name for them.
Thanks

 

Well the British called them squadron codes. I'm assuming the Luftwaffe did likewise.
Basically one set is the squadron code, and the other relates to that particular aircraft within it. In the RAF for example 'DB' would be the squadron, and 'C' would be a particular aircraft. Not too well up on the Luftwaffe though, sorry.

 

Thanks

 

I have that kind of information at home. so i'll look it up and see what i come up with, but the lettering does indeed indicate several identification of the Staffel involved. But Lettering was not alway used like the British Like AoKF KF being the Squadron Code and that A being the aircraft code, no the luftwaffe also used symbols as well such as cheverons, dashes, curved lines in mant occassions numbering was not used at all.

 

For the RAF movie I'm working on, I have 2 giant Stukas.

One has T6 in black, the Luftwaffe symbol, then a yellow C followed by a black P.

The other has a black A5, the luftwaffe symbol, a yellow vertical line (symbol? or maybe just an I or 1), and then a black L.

What would theses mean? In the script, I just have the group commander asking the squadron leader what a specific German's squadron numbers were, and he replies with "Squadron codes A5L". Wrong?
