A Caporegime (Capo) is a captain of a mafia family. A Capo is in charge of a crew of soldiers and associates, this is known as a regime. The capo is only outranked by the Consigliere, Underboss and the Don, the leader of the family. If all of those members die or retire, then the highest ranking capo is usually selected to become boss.
