GPSTC Supervisor Level 2 Practice Test

Chain of command is the formal line of authority within an organization, showing who has decision-making power and who reports to whom from top to bottom. Unity of command means each person reports to only one supervisor for a given assignment, so directions come from a single source and not from multiple leaders. In incident management, these ideas keep the response organized as it scales: everyone knows who is in charge, who they report to, and whose instructions to follow. Together, they provide clear accountability and smooth coordination, reducing confusion, overlap, or gaps in action. The other statements don’t fit because the chain of command is a formal structure, not informal or optional, and unity of command is required for every assignment, not something to be ignored or limited to non-emergency settings.
