Classification Sources
To complete the “Derived from” line, identify the applicable DD Form 254 or other classification guide. If the source is DD Form 254, include the date and applicable contract number. If the source is a classification guide, identify the guide and its date. If there are two guides, cite both. If there are more than two guides use the phrase “Multiple Sources.” Maintain a bibliography of the multiple sources.
Portion Marking
Mark each section, part, paragraph, subparagraph, or portion to show the level of classification or that a portion is unclassified. Use a capital letter in parentheses: (S), (C) or (U) to denote Secret, Confidential, and Unclassified respectively.
Headings, Subheadings, and Captions
Place the abbreviated marking before the first word of a heading, subheading, or caption. This marking must indicate the classification of that item only, except when a second level heading is included in the first line of a paragraph. In this case, the marking must show the classification of the paragraph.
Lists are marked as follows:
- (U) Items preceded by letters
- (C) This subordinate portion contains (CONFIDENTIAL) information
- (U) Items in list preceded by numbers
- (S) This subordinate portion contains (SECRET) information
- (C) This subordinate portion contains (CONFIDENTIAL) information
Footnotes
Mark each narrative footnote with its own classification preceding the footnote.
Illustrations
Fully enclose each illustration, photograph, figure, graph, drawing, chart, table and similar display material, and clearly show its classified or unclassified status. Place the unabbreviated classification marking in the lower left corner of the box, i.e. SECRET or CONFIDENTIAL.
Figure Captions
Use a letter in parentheses to indicate the classification of a figure caption. Place the classification marking between the figure number and first word of the caption. Center the caption below the image area.

Table Titles
Use a letter in parentheses to indicate the classification of a table title. Center the table number and title on one line above the table with the classification marking between the number and first word. Type the table classification in the lower left corner of the table.
