Army Good Conduct Medal

The criteria for a Good Conduct Medal are defined by Executive Orders 8809, 9323, and 10444. The medal is awarded to any active-duty enlisted member of the United States military who completes three consecutive years of "honorable and faithful service". Such service implies that a standard enlistment was completed without any non-judicial punishment, disciplinary infractions, or court martial offenses. If a service member commits an offense, the three-year mark "resets" and a service member must perform an additional three years of service without having to be disciplined, before the Good Conduct may be authorized.
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 service member killed in the line of duty.
