Basic statutory authority pertaining to the Army national cemeteries is in chapter 7, title 24, United States Code, entitled ``National Cemeteries.'' Many of the provisions of this chapter were repealed by section 7(a) of the National Cemeteries Act of 1973 (Pub. L. 93-43, 18 June 1973, 38 U.S.C. 1000 et seq.); but section 7(b) provides that nothing in this section shall be deemed to affect in any manner the functions, powers, and duties of the Secretary of the Army with respect to Arlington and Soldiers' Home National Cemeteries.
