Who ensures appropriate classification markings are used on correspondence?

The correct answer revolves around the responsibilities associated with maintaining the integrity of classified information. The Executive Officer (XO) typically plays a pivotal role in the administration of an organization, which includes overseeing the proper implementation of policies and procedures. This extends to ensuring that correspondence contains the appropriate classification markings, thereby fulfilling compliance with security protocols.

The XO often acts as a liaison between the Commanding Officer and the rest of the command, ensuring that everyone adheres to established standards and practices regarding classified information. This position is critical because the XO's involvement helps to maintain the security of sensitive information, preventing unauthorized access or dissemination.

In this context, the other roles, while important, do not focus primarily on managing everyday correspondence and the correct classification of documents within the organization. The Officer in Charge, Commanding Officer, and Review Board all have significant responsibilities, but the XO is most directly involved in overseeing the application of classification markings on correspondence.
