The wyvern, a two legged dragon, by virtue of its ability to breathe fire, smoke and gas, is symbolic of the Chemical Corps mission. Wyvern is the Saxon name for viper and also suggests the chemical properties of snake venom, further alluding to the unit's mission. The collar charged with a fleur-de-lis and the sword with a wavy pale represent the unit's participation in World War II campaigns in France and the Rhineland. Cobalt blue and golden yellow are the colors traditionally associated with Chemical units.
The crest is that of the U.S. Army Reserve.
The coat of arms was approved on 7 November 1985.
