An Overseas Service Bar is an insignia worn by United States Army soldiers on the Army Service Uniform, and previously on the Army Green (Class A) and the Army Blue (Dress Blue) uniforms, that indicates the recipient has served six months overseas in a theater of war.

Overseas Service Bars are displayed as an embroidered gold bar worn horizontally on the right sleeve of the Class A uniform and the Army Service Uniform. Overseas Service Bars are cumulative, in that each bar worn indicates another six-month period. Time spent overseas is also cumulative, meaning one bar could be earned for two separate deployments totaling six months.

The Overseas Service Bars shown here as ‘Korea’ were used as Overseas Service Bars in World War II.
