a. Recognition of cryptologic information may not always be an easy task.
There are several broad classes of cryptologic information, as hollows:
(1) Those that relate to COMSEC. In documentary form, they provide
COMSEC guidance or information. Normally, COMSEC documents and materials are
accountable under the Communications Security Material Control System. Examples
are: items bearing TSEC nomenclature (TSEC plus three letters), Crypto Keying
Material for use in enciphering communications, Controlled COMSEC Items (CCI),
and cryptographic keying devices.
(2) Those that relate to SIGINT. These appear as reports in various
formats that bear security classification, sometimes followed by a five-letter
codeword (World War,II's ULTRA, for example) and often carrying warning caveats
such as "This document contains codeword material," "Utmost secrecy is necessary..
Formats may appear as messages having addressees, "from" and "to" sections, and
as summaries with SIGINT content with or without other kinds of intelligence and
comment.
(3) RDT&E reports and information that relate to either COMSEC or SIGINT.
b. Commonly used words that may help in identification of cryptologic
documents and materials are "cipher," "code," "codeword," "communications in-

CATEGORIES OF INFORMATION TO BE REVIEWED FOR DECLASSIFICATION
DEPARTMENT OF THE AIR FORCE SYSTEMS
The Department of the Air Force has determined that there are no categories
of information pertaining to specific Air Force systems that must be system-
atically reviewed for declassification but that the categories identified in
enclosure 2 of this Directive shall apply to Air Force information reviewed at
20 years.

DECLASSIFICATION CONSIDERATIONS
1. Technological developments; widespread public knowledge of the subject
matter; changes in military plans, operations, systems, or equipment; changes
in the foreign relations or defense commitments of the United States; and similar
events may bear upon the determination of whether information should be declas-
sified. If the responsible DoD reviewer decides that, in view of such circum-
stances, the public disclosure of the information being reviewed would no
longer result in at least identifiable damage to the national security, the
information must be declassified.
2. The following are examples of considerations that may be appropriate in
deciding whether information in the categories listed in enclosure 2 may be
declassified when it is reviewed:
a. The information no longer provides the United States a scientific,
engineering, technical, operational, intelligence, strategic, or tactical
advantage over other nations.
b. The operational military capability of the United States revealed by
the information no longer constitutes a limitation on the effectiveness of the
Armed Forces.
c. The information is pertinent to a system that is no longer used or
relied on for the defense of the United States or its allies and does not
disclose the capabilities or vulnerabilities of existing operational systems.
d. The program, project, or system information no longer reveals a current
weakness or vulnerability.
e. The information pertains to an intelligence objective or diplomatic
initiative that has been abandoned or achieved, and will no longer damage the
foreign relations of the United States.
f. The information reveals the fact or identity of a U.S. intelligence
source, method, or capability that is no longer employed and that relates to
no current source, method, or capability that upon disclosure could cause at
least identifiable damage to national security or place a person in immediate
jeopardy.
g. The information concerns foreign relations matters the disclosure of
which can no longer be expected to cause or increase international tension to
the detriment of the national security of the United States.
3. Declassification of information that reveals the identities of clandestine
human agents shall only be accomplished in accordance with procedures estab-
lished by the Director of Central Intelligence for that purpose.
4. Special procedures of the NSA/CSS apply to the review and declassification
of classified cryptologic information. The following shall be observed in the
review of such information:

a. COMSEC Documents and Materials. If records or materials in this cate-
gory are found in agency or department files that are not under COMSEC control,
refer them to the senior COMSEC authority of the agency or department concerned
or by appropriate channels to the following address:
Director
National Security Agency/Central Security Service
ATTN: Director of Policy (Q4)
Fort George G. Meade, MD 20755
b. SIGINT Information
(1) If the SIG[NT information is contained in a document or record
originated by a DoD cryptologic organization, such as the NSA/CSS, and is in
the files of a noncryptologic agency or department, such material will not be
declassified if retained in accordance with an approved records disposition
schedule. If the material must be retained, it must be referred to the
NSA/CSS for systematic review for declassification.
(2) If the SIGINT information has been incorporated by the receiving
agency or department into documents it produces, referral to the NSA/CSS is
necessary prior to any declassification action.

CATEGORIES OF INFORMATION FOR,WHICH CLASSIFICATION HAS BEEN EXTENDED
BEYOND 20 YEARS BY THE SECRETARY OF DEFENSE
The classification of the following categories of information has been extended
beyond 20 years by the Secretary of Defense in accordance with the provisions
of this Directive. The organization of primary responsibility is shown paren-
thetically for each category extended.
1. Information encompassing strategic and tactical cover and deception
plans, policies, procedures, and organization. (OJCS)
2. Information involving operational planning when such information would
reveal courses of action, concepts, tactics, or techniques that are used in
current operations plans that are classified. (OJCS)
3. Information revealing intelligence sources, methods, or activities in-
