What aspect of a Marine's performance does the board heavily weigh in their decision?

The board places significant emphasis on a Marine's overall military behavior, which encompasses conduct and adherence to regulations. This aspect is vital because it reflects the Marine's ability to uphold the values and standards expected of them within the Marine Corps. Demonstrating exemplary behavior not only indicates a commitment to personal integrity but also affects unit cohesion and morale. A Marine’s conduct directly influences their leadership potential and ability to serve as a role model for others.

While awards and decorations, specialized training, and social activities might enhance a Marine's profile, they do not provide the same comprehensive insight into a Marine's character and professionalism. Overall military behavior is fundamental as it inherently involves consistent application of core values like honor, courage, and commitment – essential qualities for any Marine, especially as they seek advancement in rank and responsibility.
