Shield
Cobalt blue and golden yellow (gold) are the colors traditionally associated with the Chemical Corps. The smoke bomb denotes the unit's battle history as a "Smoke Generator Battalion," it is charged with a Taeguk to indicate service in Korea, the four bursts of smoke symbolizing the unit's four decorations for that service. The lion's face commemorates European campaigns and service in World War II.
Crest
The mural crown, recalling the stone castles of Germany and France, highlights the unit's service in Europe during World War II. The five battlements of the crown reflect the unit's European campaigns. The spearhead represents the battalion's Korean War honors and decorations; red and blue are adapted from the Taeguk, which appears on the Korean coat of arms. The laurel wreath symbolizes honor and high achievement.
The coat of arms was approved on 20 September 1995. It was amended to include a crest on 2 October 1996.
