In the United States Army, tabs are cloth and/or metal arches displaying a word or words signifying a special skill that are worn on U.S. Army uniforms. On the Army Combat Uniform and Army Service Uniform, the tabs are worn above a unit's Shoulder Sleeve Insignia (SSI) and are used to identify a unit's or a soldier's special skill(s) or are worn as part of a unit's SSI as part of its unique heritage. Individual tabs are also worn as small metal arches above or below medals or ribbons on dress uniforms.
