Secretariat of National Defense

The Mexican Secretariat of National Defense (SEDENA); Spanish: Secretaría de la Defensa Nacional is the government department responsible for managing Mexico's Army and Air Forces. Its head is the Secretary of National Defense who, like the co-equal Secretary of the Navy, is directly answerable to the President. Before 1937, the position was called the Secretary of War and Navy (Secretaría de Guerra y Marina). The agency has its headquarters in Lomas de Sotelo, Miguel Hidalgo, Mexico City. Some key figures who answer directly to the Secretary are the Assistant Secretary, the Chief of Staff of the Armed Forces, and all military tribunals.
