Hello gents, some weeks ago i acquired a propaganda magazine. And one of it’s article is about indonesian native forces formed by the japanese. So there’s some identification i need help to solve in here before i put this pictures on my blog.
Is there anyone know about these shoulder sash means?

Are they some kind of instructor? Or NCO sash e.g. sergeant?

And also the armband on the man on the right.

The armband looks like a hinomaru. Kempeitai? Or non military personnel, maybe train station personnel? :confused:

Thank you.
