Some of the armor is accurate, some of it is not. There is no evidence of the shoulder or hip armor in the picture. His torso armor is called "mirror armor" or "krug armor". His helmet looks like a stylized version of a real helmet sometimes called a migfer (although I'm fairly certain that's just the word "helmet" in another language). "Chicak" is another word for ottoman helmets. The lower legs are somewhat accurate (they're poorly rendered, but all the pieces are there), but I don't know if they have a special name. I can't make out the rest of the armor enough to give you any more information than that, but he 'should' be wearing bazubands if he's supposed to be ottoman. Googling "Ottoman Armor" will show you some good results of what kind of armor they wore.
