Peaked cap

A peaked cap, forage cap, barracks cover or combination cap is a form of headgear worn by the armed forces of many nations, as well as many uniformed civilian organisations such as law enforcement agencies and fire departments. It derives its name from its short visor (American English, known as a peak in British English), which was historically made of polished leather but increasingly is made of a synthetic substitute. Other principal components are the crown, band and insignia, typically a cap badge and embroidery in proportion to rank.
