What should personnel do if they receive classified information incorrectly labeled?

When personnel receive classified information that is incorrectly labeled, the appropriate action is to notify the sender and correct the labeling. This approach ensures that the integrity of classified information is maintained and that all personnel handling the information are aware of its true classification level. Proper labeling is crucial in safeguarding sensitive data, and rectifying any discrepancies helps prevent potential mishandling or exposure to unauthorized individuals. Addressing the issue promptly promotes a culture of compliance and accountability within the organization while minimizing risks associated with classified information.
