Both were rescinded on 17 February 1959. The distinctive unit insignia included a 1 1/8 in (2.86 cm) gold colored metal and enamel device, which consisted of a shield with three red bars in the center below a bear, and a red and gold scroll below the shield, which was inscribed with the regimental motto, "Nunquam non paratus". The shield symbolized the United States Cavalry, the bear, similar to that on the Seal of California, represented the unit's California service in World War I, and the red bars symbolized three World War I field artillery units that were included in the regiment's lineage. The motto was Latin for "Never unprepared". The regiment's coat of arms was similar to the distinctive unit insignia except that it added the Organized Reserve crest, a Minuteman, and omitted the motto.
