What is the procedure for reporting lost keying/classified material?

The correct procedure for reporting lost keying or classified material requires notifying the custodian or the security manager. This is crucial because custodians and security managers are responsible for safeguarding classified materials and implementing security measures. Their immediate involvement ensures that proper protocols are followed to mitigate any potential security breaches or unauthorized access to classified information.

By informing the custodian or security manager, necessary actions can be taken in a timely manner, such as conducting an assessment of the situation, determining the extent of the loss, and coordinating any further reporting or necessary investigations. This chain of command is essential in maintaining the integrity of security measures within military operations.

In contrast, the other options may not address the specific protocols required for classified material management. Although reaching out to law enforcement, filing complaints with military police, or communicating with a command general may be appropriate in some contexts, they do not specifically align with the established protocol for handling lost keying or classified materials. The focus should always be on internal security procedures before escalating matters externally.
