The Food-borne Illness Full-scale Exercise is the most comprehensive type of emergency drill, involving real-time deployment of personnel, equipment, and resources to simulate a major incident (like a plane crash or natural disaster) across multiple agencies and jurisdictions to test entire emergency plans, coordination, and operational capabilities in a stressful, realistic environment. It combines functional aspects (like activating command centers) with "boots-on-the-ground" actions to identify gaps and improve response.
