What does span of control refer to?

• A. The number of subordinates or activities under a single commander.
• B. The geographic area covered.
• C. The length of a mission.
• D. The number of staff officers per staff section.

Answer: (D)

Span of control is about how many people or activities one supervisor can effectively oversee at a given time. In a staff organization, this translates to how many staff officers directly report to a single staff section head. That number directly shapes how well the staff can coordinate across functions, assemble options quickly, and produce timely guidance. If too many people report to one person, critical details can be missed and decision cycles slow; if too few, resources may be underutilized and coordination overhead can rise. So, the option describing the number of staff officers per staff section best captures how supervision and coordination are actually managed within a command and control context. The other ideas—geographic area, mission length, or just the total subordinates under a commander—don’t reflect the specific discipline of supervising and coordinating within a staff section.
