Shield
Yellow is the color traditionally associated with Cavalry. The "red horse," symbolizing the popular name of the regiment, is in a rampant position to denote aggressiveness and is bridled to indicate discipline. The prickly pear cactus represents service on the Mexican Border and the fleur-de-lis signifies service in France during World War I of the original 113th Cavalry.
