The Army Service Cap Device is comprised of a gilt eagle device, which is the Great Seal of the United States. In the late nineteenth century, this device on the blue infantry disc was listed as the equivalent of the roundel that appeared on headgear of many European armies. For officers, a large eagle device is worn. For enlisted men, a small version of the officer's insignia centered on a disc is worn on the front. Warrant Officers wear a gold eagle device centered on the cap. For garrison caps, generally the rank insignia is worn, but recent regulations call for the wear of the Distinctive Unit Insignia commonly worn on the now deregulated beret.
