In ICS terminology, the model should be used at all types of training evolutions, whether they involve live fire or not.

• A. It should be used only in live-fire evolutions.
• B. It is optional for most training sessions.
• C. It should be used at all types of training evolutions, whether they involve live fire or not.
• D. It is only applicable to large incidents.

Answer: (C)

Using the ICS model in every training evolution ensures consistent command, control, and coordination, and reinforces safety regardless of whether live fire is involved. The incident command system provides a defined structure for roles, responsibilities, and communication, so practicing it in all types of drills helps responders become fluent with the chain of command, span of control, and resource management. This consistency means when a real incident occurs, responders can quickly assume the right roles, establish an incident action plan, and coordinate safely and effectively, whether the exercise is high risk (live fire) or routine (non-live-fire).

Live-fire scenarios are inherently riskier, but applying the ICS framework still guides safety oversight, planning, and supervision; for non-live-fire drills, the same structure gives clarity and discipline to tasks, briefs, and debriefs. This approach isn’t optional, nor is it limited to large incidents—it's applicable to every training evolution to build practiced, reliable response.
