What marking should be on documents containing "foreign government information"?

The correct marking for documents containing "foreign government information" includes the classification level coupled with the notation "Foreign Government Information." This requirement ensures that anyone handling the document is immediately aware not only of its sensitivity but also of the specific nature of the information included, indicating that it pertains to a foreign government.

This additional notation is crucial for maintaining proper protocols in handling such sensitive data, as it informs personnel about the context of the information and the need for additional caution. Properly marking these documents helps prevent unauthorized disclosure and supports compliance with national security policies.

In contrast, merely stating the classification level without the specific notation does not provide adequate context about the nature of the information, potentially leading to mishandling. Similarly, marking it as "Confidential" with no notation or as "Top Secret" without additional information fails to communicate the crucial detail that the content relates to a foreign government, which is essential for appropriate handling and awareness among those who access the document.
