A device of silver color metal and enamel 1 1/4 inches (3.18 cm) in height overall consisting of a blue dragon's head facing front with red eyes and nostrils, the last emitting red and orange flames upward along each side; entering the animal's mouth in base the blade of a silver sword with point emerging above between the ears. On either side, entwining the flames and curving across the hilt of the sword a silver scroll bearing the motto "BRAVE AND BOLD" in blue letters.
The great strength and terrible weapons of the mythical dragon are synonymous with the enemies the Brigade may face and the sword impaling his head denotes the fighting spirit displayed in the face of great odds and the victorious results. Underneath, the unit's motto "BRAVE AND BOLD" describes the basic qualities of the men of the 198th Infantry.
The distinctive unit insignia was approved on 20 October 1967.
