Which concept is described as each firefighter reporting to a single supervisor?

• A. Unity of Command
• B. Span of Control
• C. Division of Labor
• D. SOPs

Answer: (A)

Unity of Command means every firefighter reports to a single supervisor, ensuring clear, single-direction instructions and accountability on the fireground. This setup prevents conflicting orders, makes it easier to coordinate actions, and clarifies who is responsible for decisions and outcomes. In practice, one supervisor provides priority guidance to each crew member, which reduces confusion in high-stress, rapidly changing situations. This concept differs from span of control, which focuses on how many direct reports a supervisor can manage; division of labor, which distributes tasks among roles; and SOPs, which are the written procedures guiding actions. So the concept described is Unity of Command.
