Help with a visor cap in a portrait

[km-spain]

Hi, can anybody help me to identify from which organization is the cap that this man is wearing?

Thanks in advance.

Was going to say NPEA NAPOLA or ORDENSBURG but the piece of the collar tab showing looks Wehrmacht HEER or Kreigsmarine Coastal Artillery...Billbert

I agree with billbert--coastal artillery wearing an NPEA cap.
Probably just wearing what the portrait photographer had on hand.

And the cap looks too small for him lol
