An "Underboss" is a high-ranking member of a criminal organization, typically serving directly under the boss. This position is crucial in the hierarchy, as the underboss often oversees the day-to-day operations and manages other members. The underboss acts as a key advisor and confidant to the boss, ensuring that the organization's activities run smoothly. In many cases, the underboss is responsible for enforcing the boss's orders and maintaining discipline within the group. This role can be found in various criminal enterprises, including the Mafia and other organized crime syndicates. The underboss may also step in to lead if the boss is unavailable.
