I was just wondering if the ranks of the Mafia in Sicly go by the same as the Italian Mob in America? Cause I heard the Sicilain Mafia goes by Capo-Mafiosa (the Don) and beneath him are the Soldiers

I'm guessing but I would assume
it depends on the family structure.
Mario Puzo did alot of research in his books; you may found your answer there. Or in some tell all book by a reformed gangster, generally, each mafia family has it's own set of rules an structure, and possibily different terms.
So what works in one mob family may be different in the other.
