Which statement best differentiates a full-scale exercise from a tabletop exercise?

• A. A full-scale exercise is live with participants and real-time actions; tabletop is discussion-based
• B. A tabletop is live with field operations
• C. Full-scale requires no injects
• D. Tabletop involves no scenario

Answer: (A)

The main idea here is the level of realism and how participants engage. A full-scale exercise simulates a real incident with real-time actions, field deployments, and live participation from responders using actual equipment and communications. It tests how people coordinate under pressure and how resources move and interact in a true operational environment. A tabletop, by contrast, is a discussion-based session where leaders talk through responses to a scenario without moving resources or conducting field operations. It focuses on decision making, policies, and coordination in a safe, controlled setting.

So the best differentiator is that full-scale involves live actions and participants in actual operations, while tabletop remains at the planning and discussion level without real-world field activities. The other statements don’t fit because they mischaracterize either tabletop as live field operations, deny the use of scenarios, or claim full-scale requires no injects—injects are commonly used to drive realism in both types, especially in full-scale.
