The current Navy Good Conduct Medal dates from 1961 and is issued to every active duty sailor who completes three years of honorable and faithful service. Prior to 1 January 1996, four years of honorable and faithful service was required. Service stars denote additional awards of the Navy Good Conduct Medal. The back of the Good Conduct Medal has the three words "FIDELITY ZEAL OBEDIENCE" superimposed in a semicircle. 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 or Petty Officer First Class and above, but occasionally Petty Officer Second Class.
