Highly decorated (Serbian?) officer

[kuratorium]

I have a few questions for Balkan experts, because I have no knowledge in this area: Is this a Serbian or Yugoslavian Kingdom officer?
What is his rank?
Are any of his awards interesting or even rare?
Many thanks in advance!

Neck awards is Sveti Sava (Saint Sava), first on the medal bar is Beli Orao (White eagle).

Not very rare, but also not common.

Nice photo. I'd like to have one like that.

WOW - Super piece - if it is for sale, I will be honored to take it off your hands.

He is a Serbian officer - he has high orders from Serbia, France, Romania, Czechoslowakia, Russia....
