This regulation establishes the policy for the classification, downgrading, declassification, transmission, transportation, and safeguarding of information requiring protection in the interests of national security. It primarily pertains to classified national security information, now known as classified information, but also addresses controlled unclassified information, to include for official use only and sensitive but unclassified. For the purposes of this regulation, classified national security information, or classified information, is defined as information and/or material that has been determined, pursuant to any order, to require protection against unauthorized disclosure and is marked to indicate its classified status when in documentary or readable form. It contains the minimum Department of the Army standards for the protection of classified information and material. Such standards may be enhanced but never lessened at command option. It also establishes the DA policy on the safeguarding of Restricted Data and Formerly Restricted Data as specified. It also provides guidance on the proper handling of sensitive unclassified material.
