Chicago Police Department - Structure - Insignia

Insignia

Chicago's five-pointed star-shaped badge (referred to as a "star" instead of a "badge" in the vernacular of the department) also changes to reflect the different ranks of officers. The stars of most Chicago Police officers (patrolmen through captain) are of silver-colored metal, with broad points. Command ranks have gold-colored stars with sharp points. A ring surrounding the full-color city seal in the star's center changes color for each rank within these two classifications. Like most American police forces, the officer's rank is written in an arc above the center element.

The Chicago Police Department's shoulder sleeve insignia, worn on the top of the left sleeve, is unusual in two regards.

• Its shape is octagonal instead of one of the more typical shapes used by most other American police forces.
• The embroidery colors vary depending upon the wearer's rank. In all cases, the patch is a white octagon with a full-color rendering of the city seal, ringed in gold, with "Chicago" written in an arc above the seal, and "Police" written in an arc below the seal. For patrolmen and detectives (detectives are occasionally uniformed for ceremonies and details), the octagon's outer edge is finished in dark blue thread, and the text is embroidered in dark blue thread. For sergeants, lieutenants and captains, the octagon's outer edge is finished in gold-colored thread, and the text is embroidered in dark blue thread. For "command ranks" (commander through superintendent), the octagon's outer edge is finished in gold-colored thread, and the text is embroidered in gold-colored thread.

Service longevity is reflected just above the left cuff on most long-sleeved uniforms. Five years of service are indicated by a horizontal bar, embroidered in gold-colored thread; ten years by two bars; fifteen by three bars; twenty by a five-pointed star, embroidered in gold colored thread; twenty-five by one star and one bar and so-forth.

An embroidered rendering of the flag of Chicago, its borders finished in gold-colored thread, is worn on the right shoulder sleeve.

A two-part nameplate in gold-colored metal is worn above the right pocket. The upper portion bears the officer's name; the lower portion indicates the command to which the officer is assigned.

The Chicago Police Department is one of only a handful of police agencies in the United States to use the checkered bands on its headgear, known as the Sillitoe Tartan after its originator, Percy Sillitoe, Chief Constable of Glasgow, Scotland in the 1930s. Where British, Australian and New Zealand Sillitoe tartans feature three rows of smaller squares, Chicago's has two rows of larger squares. The checkerboard colors for patrolmen, detectives, dogs and horses are blue and white; the colors for sergeants and higher ranks are blue and gold. Service caps, the campaign hats of the mounted unit, bicycle helmets, knit caps, dog collars, and horse browbands all bear the Sillitoe tartan; the edge of the ball caps' bills show a narrow, flattened Silitoe tartan. The department also uses the pattern on some signage, graphics, and architectural detail on newer police stations.
