What Are Chain of Command and Unity of Command?
Chain of command and unity of command are rules in the National Incident Management System (NIMS) and Incident Command System (ICS). They help teams in emergencies.
- Chain of Command: Shows who gives orders. It starts with the top boss and goes to workers.
- Unity of Command: Means each person has one boss. This stops confusion.
Why It Matters: In a crisis, like a storm, clear rules keep everyone safe and fast.
Example: In a flood, a firefighter listens to one team leader, not two bosses.

- Key Dates:
- 1970s: ICS started for wildfires.
- 2004: NIMS began to make rules for all emergencies.
- 2025: Most U.S. emergency teams use NIMS, says FEMA.
Chain of command and unity of command come from army rules. They keep things clear.
Fact: 90% of U.S. fire teams use NIMS, says a 2025 FEMA report.

What Is the Chain of Command in NIMS?
The chain of command in NIMS is a clear list of who’s in charge. It’s like a ladder:
- Incident Commander: The top boss who makes big plans.
- Command Staff: Helpers like safety or news people.
- General Staff: Leaders for jobs like rescue or supplies.
- Workers: People like firefighters or medics.
This helps operational coordination. Everyone knows their boss.
Example: In a storm, the incident commander tells the rescue leader to send boats. The leader tells workers. No one skips steps.
