Unity of Command means

• A. Each individual reports to only one designated supervisor.
• B. Every unit reports to the highest ranking officer.
• C. There is a separate supervisor for safety and operations.
• D. Command is rotated among several supervisors.

Answer: (A)

Unity of Command means that each person reports to only one designated supervisor, creating a single clear line of authority. In fire department operations, this keeps orders consistent and avoids conflicting directions, making accountability straightforward and communication efficient. Even with multiple units and higher-level command roles, an individual’s direct supervision remains singular, while higher-ranking officers set objectives and oversee the bigger picture.

Why the other ideas don’t fit: simply reporting to the highest ranking officer isn’t enough to guarantee a single direct supervisor for everyone; there must still be one person you directly answer to. Having a separate supervisor for safety and operations would give one person two bosses, which can lead to mixed instructions and confusion. Rotating command among several supervisors would destroy clarity of who is responsible for the decisions you follow.
