Distinctive unit insignia
A black enamel, grizzly bear passant above a stylized red enamel scroll bearing the inscription "CERTO DIRIGO ICTU" in gold letters. The design is adapted from the crest of the Coast Defenses of San Francisco where the old regiment and the majority of the companies of same were stationed since 1901 and where the new regiment will be organized and assigned. The motto "CERTO DIRIGO ICTU" (I Aim With a Sure Blow) is indicative of the character of the bear. The distinctive unit insignia was originally approved for the 6th Coast Artillery on 20 May 1924.
