An Overseas Service Bar is an accoutrement on United States Army Army Service Uniform and previously on the Army Green (Class A) and the Army Blue (Dress Blue) uniforms that indicates a soldier has served six months of service in a combat zone.
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.[1] 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
