History
The District of Columbia National Guard descends from the 25th Battalion of the Maryland Militia, Headquartered in Georgetown, Maryland, formed 1776 to fight in the American Revolutionary War. After Congress established the Federal District in District of Columbia Organic Act of 1801, local Militia units were reorganized again, to form what would become the District of Columbia National Guard. Supervision and control of District of Columbia National Guard was delegated by the President of the United States to the Secretary of Defense pursuant to Executive Order 10030, 26 January 1949 with authority given to the Secretary to designate officials of the National Military Establishment to administer affairs of the District of Columbia National Guard. The Secretary of the Army was directed to act for the Secretary of Defense in all matters pertaining to the ground component, and the Secretary of the Air Force was directed to act in all matters pertaining to the air component of the District of Columbia National Guard by Secretary of Defense memorandum, 2 February 1949. Founded in 1997, the Mobilization Augmentation Detachment of the DC National Guard primary mission was to support the National Guard Bureau Operations Staff and Emergency Operations Center in Arlington, Virginia. On 27 September 2001, following the 9/11 terrorist attacks on America, the unit was the first Army Reserve component mobilized to support the Global War on Terrorism. Our outstanding performance and commitment prompted the decision to expand the unit into a Command, with a larger role, and opportunities for over 100 Officers and NCOs. The MAC is heavily involved in operations throughout the National Capital Region.
