MARKING CLASSIFIED MATERIAL
Classified material is marked so that personnel
know the classified nature of the material, to make sure
the material receives the degree of protection required,
and to help extract, paraphrase, downgrade, and
declassify the material.
All classified material is marked so you know the
following information about the material:
The level of classification
The part(s) that contain(s) or reveal(s) classified
information
How long the material is to remain classified
Additional measures needed to protect the
material
Overall Markings
Material is marked so the security markings are
easy to see and recognize. Classified documents are
marked on their face and back cover and top and bottom
center to show the highest overall classification level of
the information they contain. (NOTE: Titles of
classified documents are usually unclassified.) On
documents, the classification level is marked or
stamped in capital letters larger than the type used in the
text to alert anyone handling the document that it is
classified. Material is marked as follows:

devices used with AIS and word processors are marked
using the appropriate SF label to indicate the highest
overall classification level of information contained in
the storage media.
PHOTOGRAPHS, SLIDES, AND TRANS-
PARENCIES.The face of a classified photograph is
marked with its highest overall classification level and
associated markings. If this is not possible, these
markings are placed on the back of the photograph.
These markings are stamped or permanently affixed by
pressure tape, labels, or other similar means.
Slides or transparencies (fig. 22-2) are marked with
their highest overall classification level and association
markings on the image area, border, holder, or frame.
Groups of slides or transparencies used and stored
together as a set are marked with their highest overall
classification level and associated markings.

containers are marked in the same manner.

have an audible statement at the beginning and end of
each recording. This statement identifies the highest
overall classification level and associated markings of

prominently marked with the highest overall
classification level and associated markings of the

items are clearly marked to show their highest overall
classification level (fig. 22-5).
Portion Markings
Each portion such as the title, section, part,
paragraph, or subparagraph of a classified document is
marked to show its classification level. By doing this, a
document is marked so you know what part or parts
contain or reveal protected information. The
classification level of a part of a document is shown by a
classification symbolTS for Top Secret, S for Secret,
C for Confidential, and U for unclassified. The symbol
