This Interagency Threat Assessment and Coordination Group (ITACG) Intelligence Guide for First Responders is designed to assist first responders in accessing and understanding Federal intelligence reporting and to encourage the sharing of information. The information in this guide was derived, compiled, and adapted from existing unclassified Intelligence Community and open-source references. The ITACG consists of state, local, and tribal first responders from around the United States and federal intelligence analysts from the Department of Homeland Security, Federal Bureau of Investigation, and National Counterterrorism Center working to enhance the sharing of federal information on counterterrorism, homeland security, and weapons of mass destruction with state, local, and tribal consumers of intelligence.
