Portion Markings
Mark each portion (section, part, paragraph,
or subparagraph) of a classified document to
show its level of classification or the fact that
it is Unclassified. These markings eliminate any
doubt as to which portions of a document contain
or reveal information requiring protection.
However, be sure you consider each portion for
classification on the basis of its content and its
association with other information. Place the
appropriate parenthetical symbol immediately
following the portion letter or number. In the
absence of letters or numbers, place the
appropriate symbol immediately before the
beginning of the portion.
When a major numbered or lettered paragraph
and all of its subparagraphs are Unclassified, you
don’t need to mark each paragraph. Marking the
lead-in paragraph with a (U) is sufficient.
