__NOTOC__ A caporegime or capodecina, usually shortened to just a capo, is a rank used in the Mafia for a made member of the crime family who heads a "crew" of soldiers and has major social status and influence in the organization. Caporegime is an Italian word, which is used to signify the head of a family in Sicily, but has now come to mean a ranking member, similar to captain or senior sergeant in a military unit. In general, the term indicates the head of a branch of an organized crime syndicate who commands a crew of soldiers and reports directly to the Don (Boss) or an Underboss or Streetboss.
