"The SimCell is an exercise area where controllers generate and deliver injects, and receive player responses to non-participating organizations, agencies, and individuals who would likely participate actively in an actual incident. Physically, the SimCell is a working location for a number of qualified professionals who portray representatives of non-participating organizations, agencies, and individuals who would likely participate during an actual incident".
