When you are required to conduct wide area emergency preparedness training - be it in the setting of a CBRNe school, a dedicated military center or an industrial facility - the ongoing challenge for any CBRNe instructor is to be able to create a scenario that is realistic, safe, reliable and cost effective.
Trainees need to be equipped with the practical knowledge and skills to respond with confidence to an enormous variety of potential live incidents. And each threat brings with it a unique set of practical, physical and psychological tasks that need to be 'experienced' in order to be understood.
