What must a U.S. classified document containing NATO information include?

The selection that indicates a clear identification of NATO classified information as a requirement for U.S. classified documents containing NATO information highlights an essential aspect of information handling within the context of NATO and U.S. guidelines. Specifically, NATO requires that any classified information derived from its material be distinctly marked to ensure proper recognition and handling by personnel who have the necessary clearance.

When documents are shared among NATO member nations, it is crucial that the documents explicitly state the nature of the NATO classification. This identification helps to protect sensitive information and maintains the integrity of the data being shared, as it informs users of the guidelines and responsibilities regarding the handling, dissemination, and potential impact of the information contained within those documents.

While a label indicating the level of classification and a classification authority signature are vital elements in the classification process, the unique context of NATO information necessitates the explicit identification of that information as part of adhering to NATO standards. This ensures that all personnel are aware of the document’s origin and the specific protection measures required.
