What manual outlines the responsibilities of a Staff Sergeant?

The Army Leadership Manual (ADP 6-22) is the correct response because it serves as a comprehensive guide on leadership practices within the Army, directly addressing the roles and responsibilities of non-commissioned officers (NCOs), including the Staff Sergeant. This manual outlines essential leadership principles, values, and the expectations placed on leaders at various levels, making it invaluable for understanding the specific duties and responsibilities of a Staff Sergeant.

By focusing on leadership development, ADP 6-22 emphasizes the importance of effective communication, mentoring subordinates, and fostering a positive command climate, all of which are integral to the role of a Staff Sergeant in ensuring mission success and troop welfare.
