What title is given to one of the offices required in a unit?

The title of Chairman is often used in organizational contexts to denote a leader or presiding officer of a unit, such as a board or committee. This role typically involves overseeing meetings, ensuring that the group operates effectively, and representing the unit in official capacities.

The Chairman’s responsibilities can include setting the agenda for meetings, facilitating discussions, and guiding the decision-making process, which positions them as a crucial figure in the governance and operational framework of the unit.

While other titles such as Manager, Director, and Supervisor also denote leadership roles, the term "Chairman" specifically aligns with the context of overseeing a unit's operations or serving in an official capacity within a formal organizational structure.
