The Good Conduct Medal, each one specific to one of the five branches of the U.S. Armed Forces, is currently awarded to any active duty enlisted member of the United States military who completes three consecutive years of "honorable and faithful service".

the Good Conduct Medal is awarded for exemplary behavior, efficiency, and fidelity in active Federal Military service. It is awarded on a selective basis to each soldier who distinguishes himself/herself from among his/her fellow soldiers by their exemplary conduct, efficiency, and fidelity throughout a specified period of continuous enlisted active Federal military service. Qualifying periods of service include each three years completed after 27 August 1940 or, for first award only, upon completion of at least one year upon termination of service if separated prior to three years. Also for the first award only, for those individuals who died before completing one year of active Federal military service if the death occurred in the line of duty. The immediate commander must approve the award and the award must be announced in permanent orders.

The "loops" indicating subsequent awards were called "hitches", a "hitch" being three years of service. During the Vietnam War it was known as the "Dentyne wrapper" (chewing gum brand) owing to it being red and white like the medal's suspension ribbon.
