Joint Force Headquarters National Capital Region (JFHQ-NCR) is directly responsible for the homeland security and defense of the Washington D.C. area as well as surrounding counties in Virginia and Maryland. Primarily made up of joint military units within the National Capital Region, the JFHQ-NCR assists federal and local civilian agencies and disaster response teams in the event that the capital area's security is or possibly could be breached by acts of terrorism. Officially activated on September 22, 2004, JFHQ-NCR is part of United States Northern Command.
After the terrorist attacks on the World Trade Center and The Pentagon on September 11, 2001, military and civilian leaders recognized a need for strong cooperation and communication between agencies and national and local units in times of emergency or to prevent such attacks in the first place, something that had been severely lacking prior to that time. USNORTHCOM was subsequently established, taking the lead of several JTFs throughout the U.S. that are subordinate to the Command and charged with homeland security. The Joint Force Headquarters for the National Capital Region was created for the sole purpose of preventing and responding to future terrorist attacks within the Washington, D.C. area and its surrounding cities and counties.
JFHQ-NCR officially came into being in September 2004. However, the unit had been operating in part for at least a year prior to its official creation. Major General James T. Jackson, the Military District of Washington (MDW) Commander at the time of the September 11th attacks, was the first to take hold of the concept of the new Headquarters and began to piece various aspects of it together, particularly seeing and responding to the need for a mobile command center and a more effective central command and control headquarters. When MG Galen B. Jackman replaced Jackson in 2003, Jackman solidified the role of JFHQ, commanding the response to various regional emergencies and National Special Security Events (NSSE), proving the potential of JFHQ-NCR. When the organization finally stood up in the fall of 2004—after having had a year of practice—it was fully operational and able to provide an effective answer to the NCR's growing security concerns.
