Which term describes the principle that each firefighter reports to only one supervisor?

• A. Span of control
• B. Team integrity
• C. Personnel accountability
• D. Unity of command

Answer: (D)

Unity of command means each firefighter reports to only one supervisor. This creates a single source of authority, so orders and priorities come from one person. In fast-paced incidents, this avoids conflicting instructions that can cause confusion, delays, or unsafe actions. It also makes accountability clear—everyone knows who is in charge and who to report to, which strengthens safety and coordination on the scene. Span of control, by contrast, describes how many direct reports a supervisor can effectively manage at once, ensuring supervision is practical and not spread too thin. Team integrity focuses on keeping the unit cohesive, while personnel accountability is about tracking who is where and what everyone is doing. These concepts support unity of command but do not define the reporting relationship itself.
