The Navy and Marine Corps Commendation Medal may be awarded to service members who, while serving in any capacity with the Navy or Marine Corps, distinguish themselves by heroism, outstanding achievement or meritorious service (but not of sufficient nature to warrant a higher decoration).
Acts of Heroism
To be awarded for heroism, the act must be worthy of special recognition but not the degree required for the Bronze Star Medal when combat is involved or the Navy and Marine Corps Medal when combat is not involved.
Meritorious Achievement
To be awarded for meritorious achievement, the act or acts must be outstanding and worthy of special recognition, but not to the degree required for the Bronze Star Medal or Air Medal when combat is involved or the Meritorious Service Medal or Air Medal when combat is not involved. The achievement should be such as to constitute a definite contribution to the naval service, such as an invention or improvement in design, procedure or organization.
Meritorious Service
To be awarded for meritorious service, the service must be outstanding and worthy of special recognition, but not to the degree required for the Bronze Star Medal or Air Medal when combat is involved or the Meritorious Service Medal or Air Medal when combat is not involved. the award may cover an extended period of time during which a higher award may have been recommended or received for specific act(s). The criteria, however, should not be the period of service involved, but rather the circumstances and conditions under which the service was performed. The performance should be well above that usually expected of an individual commensurate with the individual's grade or rate, and above that degree of excellence which can be appropriately reflected in the individual's fitness report or personnel records.
