Threats to the United States and U.S. interests are evolving. Trends may shift in the type of threat or method of attack, but the underlying drivers remain constant. What may happen in one location could certainly happen in any location. As a nation, we must adapt to overcome these challenges, leveraging federal, state, local, and international partnerships. Collaborating allows us to foster creativity and innovation to address the many complexities facing response organizations and the broader homeland security enterprise.


Please join the Maryland-National Capital Region Emergency Response System and community partners as we “Reimagine the Threat Landscape,” exploring some of the emerging threats and how we should adjust our posture moving forward.


Specific topics covered include:


        • Analysis of January 6, 2021, events at the United States Capitol


        • Responder safety and health


        • Supply chain disruption for emergency services


        • The use of small unmanned aerial systems (sUAS) in public safety operations


        • Engaging public/private partnerships from an emergency management perspective
