Caporegime
A caporegime or capodecina, usually shortened to just a capo, is a term used in the Mafia for a high-ranking made member of a 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.
Background
The Mafia, particularly the American Mafia, is typically divided into distinct and partially independent "crews" headed by a "capo" or leader of the individuals. Individual crew members report to the capo. The crew collects protection and other money for the capo, who at regular intervals gives a share (or "taste") of the collected money to the underboss and/or the boss. Estimates of average income of a capo varies and is difficult to quantify. Income is dependent on the success and size of a capo's crew and the state of the economy at the time.
