The term that best describes a Marine's responsibilities and authority is "Command." In a military context, command represents not only the authority to give orders but also encompasses the responsibilities that come with that authority. A command is understood as the ability to direct personnel, make decisions, and carry out operations within the scope of one's assigned position.

When Marines receive a command, they are expected to understand the implications of those responsibilities, including the welfare of their subordinates and the successful completion of missions. Command also implies accountability, where leaders are responsible for the actions and performance of their units. This heavy responsibility is a crucial part of Marine Corps culture, fostering leadership development and operational effectiveness.

Roles, assignments, and duties also contribute to a Marine's overall responsibilities; however, they do not fully encapsulate the breadth of authority inherent to command. Role refers to a function or expected behavior within a unit, assignment pertains more to the tasks given to an individual, and duty describes the obligation to perform assigned tasks but does not inherently include authority. Command integrates these aspects while highlighting the leadership and accountability expected of a Marine in a position of authority.
