Army Doctrine Publication (ADP) 1 is prepared under the direction of the Chief of Staff of the Army and is his vision for the Army. It states what the Army is, what the Army does, how the Army does it, and where the Army is going. It establishes the Army?s contribution to America?s landpower. ADP 1 delineates the Army?s mission, purpose, and roles, deriving them from the Constitution; the Congress, in Title 10, United States Code; and the Department of Defense, in Department of Defense Directive 5100.01. Army doctrine supports and is consistent with joint doctrine. This publication connects Army doctrine to joint doctrine as expressed in the relevant joint publications, especially Joint Publication (JP) 1, Doctrine for the Armed Forces of the United States, and JP 3-0, Joint Operations.
