What markings must you include when finalizing a draft document that contains secret information?

When finalizing a draft document that contains secret information, it is essential to include all standard markings to ensure proper identification and handling of the classified content. Standard markings typically include the classification level (in this case, "Secret"), handling instructions, and any additional designations required for protection and dissemination. This comprehensive approach ensures that those who access the document are aware of its sensitivity and the precautions necessary for its management.

Additionally, including all standard markings helps to maintain compliance with established security protocols, providing clarity in communications and minimizing the risk of unauthorized disclosure. This approach underscores the importance of properly marking classified documents to facilitate responsible management and protection of sensitive information.
