All but one are core members of Organized Crime Model.

Lawyers
Boss
Consigliere
Underboss

The only member that is not part of the core Organized Crime Model is lawyers. While lawyers may have associations with organized crime groups, they are not considered core members of the structure. The other three positions - boss, consigliere, and underboss - are key roles within the hierarchy of an organized crime group. The boss is the highest-ranking member who makes the major decisions, the consigliere acts as an adviser and counselor to the boss, and the underboss is the second-in-command who helps run the daily operations of the organization.
