What does unity of command ensure on an incident?

• A. Each subordinate reports to multiple supervisors.
• B. Subordinates report to more than one supervisor.
• C. There is no fixed reporting structure.
• D. Unity of command ensures each subordinate reports to only one supervisor.

Answer: (D)

Unity of command means that every person on the incident has a single direct supervisor. This creates a clear line of authority and one set of instructions for each worker, which reduces the risk of conflicting orders and improves accountability and decision-making speed. If someone reported to more than one supervisor or had no fixed reporting structure, conflicting directives and confusion would arise, hampering coordination. Therefore, the correct understanding is that each subordinate reports to only one supervisor.
