Why russians have green shoulder straps on one pics and red on other. Why I saw green furage hat on 1 pic. What colour was russian artillery crew.
The hat is easily explained as it is actually green, however troops were issued with a white cover to put over it during summer. I've seen pics where they clearly haven't and have green hats, white tunics and green trousers. Looks great so that's how I'll paint mine when I get around to it.
I can only think of one pic showing artillery crew and that's the Osprey one shown further back, hang on...
As you can see, they're also in green/white/green. (they're in the background).
As to the shoulder boards, I think that was to show company type/army/origin. I don't have the books with me to check though.
