"Title 10, United States Code, Section 2674 (f) (2) provides the following definition: The term "National Capital Region" means the geographic area located within the boundaries of (A) the District of Columbia, (B) Montgomery and Prince Georges Counties in the State of Maryland, (C) Arlington, Fairfax, Loudoun, and Prince William Counties and the City of Alexandria in the Commonwealth of Virginia, and (D) all cities and other units of government within the geographic areas of such District, Counties, and City. Section 7302(a) (7) of the Intelligence Reform and Terrorism Prevention Act of 2004 (Pub. L. 108-458), December 17, 2004, has since amended the definition of the National Capital Region: The term "National Capital Region" or "Region" means the area defined under section 2674(f) (2) of title 10, United States Code, and those counties with a border abutting that area and any municipalities therein. However, the Homeland Security Act of 2002 limits the purview of the NCRC's oversight and coordination function within the boundaries of the NCR as defined under section 2674(f) (2) of title 10, United States Code".
