The Center for Domestic Preparedness (CDP) Integrated Capstone Event (ICE) program provides the opportunity for multiple disciplines to work together in a culminating, all-hazard, mass casualty incident training exercise. The ICE promotes interdisciplinary response where first responders and first receivers are challenged to conduct response operations within the Incident Command System, with students filling various roles based on their experience and course objectives.
