• D. The succession of commanders superior to subordinates through which command is exercised.

Answer: (D)

The chain of command is the formal line of authority and responsibility in the organization, along which orders are issued and accountability flows. It defines who has the authority to give directions and who is responsible for carrying them out, creating a clear path from the highest leaders down to every soldier. Each level has a direct superior and a direct subordinate, so authority moves downward and feedback or reports move upward. In practice, a platoon leader’s orders go to the platoon sergeant and squads, who execute and then report back up, with the platoon leader reporting to the company commander, and so on up the hierarchy. Unity of command—each subordinate answering to one primary supervisor—helps prevent conflicting instructions and keeps action coordinated. The chain of command isn’t just about a line for supply requests or a roster of officers; its core purpose is the authoritative structure that enables coordinated action and accountability from top to bottom.
