(a) When the Director, Office of Classification, makes the initial determination that information is RD, he or she determines the appropriate level of the information based on the damage that would occur if there was an unauthorized disclosure of the information. The Director, Office of Classification, also determines the level for TFNI, and, jointly with the appropriate DoD official (as specified in DoD Instruction 5210.02 or successor instructions) determines the level for FRD information.
(b) The three classification levels of RD, FRD, and TFNI are:
(1) Top Secret. Top Secret is applied to information that is vital to the national security the unauthorized disclosure of which could reasonably be expected to cause exceptionally grave damage to the national security that the appropriate official is able to identify or describe.
(2) Secret. Secret is applied to information, the unauthorized disclosure of which could reasonably be expected to cause serious damage to the national security that the appropriate official is able to identify or describe.
(3) Confidential. Confidential is applied to information, the unauthorized disclosure of which could reasonably be expected to cause undue risk to the common defense and security that the appropriate official is able to identify or describe.
