What should happen to technical documents if their classification status changes?

When the classification status of technical documents changes, it is essential that they be reassigned a new distribution statement. This is necessary to ensure that the information is handled in accordance with its new classification level. A distribution statement specifies who is allowed to access the document based on its classified status and the sensitivity of the information contained within it.

Reassigning a new distribution statement helps maintain compliance with security protocols and ensures that only authorized personnel can view or use the document, reflecting its updated classification. This process is crucial for protecting sensitive information and adhering to regulations regarding the handling of classified materials.

The other options do not align with proper protocol for handling changes in classification status. Destruction or public disclosure of the document could compromise security, and retaining the original markings could lead to confusion regarding who is authorized to access the information.
