This Programme is designed for guard forces, police, first responders and national-level civilian and military response forces that are responsible for responding to a nuclear security event. It covers best practices for planning an armed response to facilities with both armed and unarmed guards. It also covers issues surrounding public order. The goal is to present all of the issues and arguments that must be considered when designing, planning, training for and carrying out effective response. Participants will then be able to adapt these considerations to best meet the needs of their own country and region.
