Symbolism: The green shield recalls the Mexican War. The National flag bore fifteen stars during the War of 1812. The white cross represents the service of the Regiment in the Civil War; the arrow, the Indian Wars; the castle, the War with Spain; the bolo, the Philippine Insurrection; and the fleur-de-lis, World War I. Prior to the approval of the coat of arms, the crest and motto were in use by the Regiment for many years.
