Navy Good Conduct Medal dates from 1961 and is issued to every active duty sailor who completes three years of honorable and faithful service. Before 1996, four years of honorable and faithful service was required. During times of war, the Good Conduct Medal may be awarded for one year of faithful service. The Good Conduct Medal may also be awarded posthumously, to any soldier killed in the line of duty. Upon 12 years of honorable and faithful service, sailors are also allowed to wear gold-colored version of their Petty Officer insignia, something usually seen with those with the rank of Chief Petty Officer and above, although a few with the rank of Petty Officer 1st Class (usually in the Navy Reserve) have their version of this rank insignia. Service Bronze or Silver stars denote additional awards of the Navy Good Conduct Medal.
