Good Conduct Medal, Navy, type 1

The Good Conduct Medal is one of the oldest military awards of the United States Armed Forces. The U.S. Navy's variant of the Good Conduct Medal was established in 1869, the Marine Corps version in 1896, the Coast Guard version in 1923, the Army version in 1941, and the Air Force version in 1963; the Air Force Good Conduct Medal was discontinued from February 2006 to February 2009.
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.

The "U.S.N." Type I medal was authorized on 26 April 1869 and was produced by E. V. Haughwout Company of New York. The medal was issued with a red, white and blue material suspension ribbon without a suspension pin. The medal is in the design of a Maltese cross and the name of the recipient was engraved on the reverse.
