What is the required action a Marine must take after completing a request mast?

After completing a request mast, a Marine is required to make a written statement on their degree of satisfaction. This action is crucial as it allows the Marine to reflect on the outcome of their request and convey how their concerns were addressed. It serves both as documentation of the process and a means for the command to gain insight into the effectiveness of their handling of such requests. By providing feedback, Marines contribute to improving the overall command climate and responsiveness to service members' issues.

The focus on this written statement also underscores the importance of open communication within the ranks and the accountability of leadership to the needs of their Marines. This step ensures that there is a formal record that can potentially identify patterns or areas for improvement in leadership practices or policies.

The other options may seem relevant in the context of complaints or feedback mechanisms, but they do not capture the specific action outlined in the Marine Corps policies regarding the conclusion of a request mast.
