While many of the figures in the Red Box Cops set are civilian, most are in fact, American uniformed police officers from the 1920s, and 1930s.
These long coats can be either cloth or leather, and typically would be dark blue or black. Some agencies wear tan or dark brown, or even two tone uniforms with tan tops and green trousers.
Many rural areas are serviced by a county sheriff and one or more deputy sheriff officers. They do not always wear the same uniform as city police and sometimes wear little more than a badge to indicate their office. Often their population is so small that everyone knows who they are on site without a uniform. The sheriff is usually an elected official, the police chief is typically appointed by the city mayor or a civil service position.
