Housed in the Château since 1948, the SHAT is the record centre for the Army, the central administration of the Ministry of Defence, the common services for the three forces, and the General Secretariat of National Defence.
It is also a body in charge of historical studies and publications (particularly the Revue Historique des Armées), and the custodian of its Army's traditions; indeed, the traditions division is in charge of two museums housed at the Château: the Musée de la Symbolique Militaire, inaugurated in 1995, and Musée de Chasseurs.
