Which role typically does not belong to a student officer in NJROTC?

The role that typically does not belong to a student officer in NJROTC is the Naval Science Instructor. This position is filled by a qualified adult who is a member of the Navy or Marine Corps and is responsible for providing instruction, guidance, and support to the cadets. The Naval Science Instructor plays a crucial role in the leadership and educational structure of the program, but they are not students themselves.

In contrast, roles such as Executive Officer, Commanding Officer, and Cadet are all positions that can be held by student officers. The Executive Officer assists the Commanding Officer in executing the unit's plans and directives, while the Commanding Officer oversees the entire unit and holds ultimate responsibility for its operations and discipline. Cadets are the students who comprise the unit and are engaged in learning leadership, citizenship, and naval skills. Thus, the defining characteristic of the Naval Science Instructor's role distinguishes them from the positions held by student officers.
