A gold color metal and enamel device 1 1/8 inches (2.86 cm) in height overall consisting of a gold shield bearing on a red pile between two blue piles reversed, each charged with white bars wavy, a sea lion grasping a sword in its dexter paw, all of gold, the shield within a three segmented red scroll inscribed on the dexter segment "READY" on the center segment in base "WITHOUT" and on the sinister segment "REASON" in gold letters.
Yellow is the color used for Armor, the former designation of the unit. The blue represents the Pacific Theater where the unit was engaged in World War II and the three wavy bars denote the campaigns of New Guinea, Western Pacific and Southern Philippines. Arrowheads for two amphibious assault landings are symbolized by the two reversed piles and the award of the Philippine Presidential Unit Citation is indicated by the red pile in center charged with a gold sea lion, adapted from the seal of the President of the Philippines.
The distinctive unit insignia was originally approved for the 152d Armor Regiment on 16 July 1970. It was redesignated effective 30 September 2002, for the 152d Chemical Battalion, Alabama Army National Guard.
