It will be the basis for supplying real property information to offices of congressional committees, the Department of Defense, Headquarters, Department of the Army, General Services Administration, and other interested Government agencies. Inquiries or requests for information by committees of the U.S. Congress or individual members of the U.S. Congress will be coordinated with the Office of the Chief, Legislative Liaison, in accordance with Army Regulation (AR) 1–20.
