On Sept. 11, 2001 no one believed the National Capital Region would be a target for those who wish to do us harm. As a nation, we found that to be false. In direct response to the events of that fateful day, JFHQ-NCR was established as the responsible headquarters for land-based homeland defense, defense support to civil authorities and incident management in the national capital region. We have unique skills and are prepared to defend people, territory, critical infrastructures and sovereignty in a supporting role to a lead federal agency.
On a 24/7 basis JFHQ-NCR monitors security requirements; coordinating with the military services, the Department of Homeland Security and local first responders in identifying capabilities the military can provide in case of an emergency or National Special Security Event (NSSE). Once an event is designated, the command becomes a Joint Task Force-National Capital Region (JTF-NCR). JTF-NCR then directs military assistance to federal and civil authorities in safeguarding the nation’s capital.
