Because the [[Constitution of the United States|Constitution]] vests all military authority in [[United States Congress|Congress]] and the president, the statutory authority of the secretary of defense is derived from their constitutional authority. Since it is impractical for either Congress or the president to participate in every piece of Department of Defense affairs, the secretary of defense and the secretary's subordinate officials generally exercise military authority.
