Final answer:
The frequency of reports by the CNO and CMC on combat decorations awarded is not detailed in the references and typically would follow Department of Defense regulations.
Step-by-step explanation:
Typically, such requirements would be stipulated by Department of Defense policy or military regulations, which may not be publicly available in grand detail or may vary depending on circumstances and operational needs. To answer this question accurately, it would be necessary to refer to the relevant directives or regulations that govern military reporting requirements. These documents would outline the procedures and frequency for reporting combat decorations by high-level military officials like the CNO and CMC. However, the provided references discussing the increased operational tempo and presidential announcements in times of conflict do not contain information directly related to the reporting of award decorations.
