). The Secretary is appointed by the President by and with the approval of the Senate, and is a member of the Cabinet. By statute the secretary must be a civilian who hasn't served in the active component of the armed forces for at least 10 years (- Note that Congress had passed a law to allow George Marshall to be appointed in 1950 despite having only been a civilian since 1945). The Secretary of Defense is sixth in the presidential line of succession.

History

The position was created in 1947 when the Navy, Army, and newly created Air Force were merged into the new National Military Establishment. In the same massive reorganization, the Secretary of War was replaced by the Secretary of the Army and, along with the Secretary of the Navy and the new Secretary of the Air Force, became a non-Cabinet position placed under the Secretary of Defense. In 1949, the National Military Establishment was renamed the Department of Defense, which remains the current name of the department.

Organization

Within the U.S. Armed Forces, the Secretary of Defense is often referred to as SecDef.
   The SecDef and the President together constitute the National Command Authority (NCA), which has sole authority to launch strategic nuclear weapons. All nuclear weapons are governed by the two-man rule, even at the highest levels in government. Both individuals must concur before a strategic nuclear strike may be ordered.
   The SecDef, as the head of the United States Office of the Secretary of Defense, is assisted by a Deputy Secretary and five Under Secretaries in the fields of Acquisition, Technology & Logistics; Comptroller/Chief Financial Officer; Intelligence; Personnel & Readiness; and arguably the most important, Policy. All of these positions require Senate confirmation.
   The Secretary of Defense also supervises the six members of the Joint Chiefs of Staff and the commanders of the ten Combatant Commands.
   Along with the Secretary of State, the Attorney General and the Secretary of the Treasury, the Secretary of Defense is generally regarded as one of the "Big Four" important cabinet officials.
