An Overseas Service Ribbon is a service military award of the United States military which recognizes those service members who have performed military tours outside the borders of the United States of America. There are different versions of the Overseas Service Ribbons for the U.S. Army, U.S. Navy, U.S. Air Force, U.S. Space Force, and the U.S. Coast Guard. Both the U.S. Navy and the U.S. Marines receive the Navy and Marine Corps Overseas Service Ribbon. Army The Army Overseas Service Ribbon was first issued in August 1981. It is presented to any member of the United States Army who completes a standard overseas tour of duty. The length of a standard tour is dependent upon the duty location and whether the Soldier is accompanied or unaccompanied with a spouse/family member(s). The tour in question may be cut 1 month short due to manning requirements (not due to Soldier misconduct) and still receive full credit for the tour length. There are 2 types of tour designations, long tours (24+ months) and short tours (6–23 months). Anything shorter than 6 months is considered TDY (Temporary Duty Assignment). The standard unaccompanied Korean tour is 12 months, and accompanied is 24 months. The German tour is 36 months for unaccompanied and accompanied. Combat tours are typically 6–12 months and can extend beyond during critical periods. The Iraqi Surge campaign tour was 15 months. In the 11 December 2006 revision of AR 600-8-22 (Military Awards), the Army eliminated the policy which had restricted the awarding of the Overseas Service Ribbon when another campaign or service medal is awarded. Additional awards of the Army Overseas Service Ribbon are denoted by award numerals. For those Army service members performing overseas duty prior to 1981, the Army Overseas Service Ribbon may be awarded retroactively, provided that a service member was on active duty subsequent to 1981. For time served in designated combat zones, the Army also issues an Overseas Service Bar. Navy and Marine Corps The Navy and Marine Corps Overseas Service Ribbon was first proposed in 1968, but not authorized until 17 September 1986. The ribbon is awarded to any member of the Navy or Marine Corps who completes one year of consecutive or cumulative duty at a permanent overseas duty station. For inactive members of the reserve components, the first award is authorized upon completion of either 30 consecutive or 45 cumulative days of overseas
