On a dark blue oval with a 1/8 inch (.32 cm) red border, 3 1/8 inches (7.94 cm) in height and 2 1/2 inches (6.35 cm) in width overall, between two white stars are ten silver spears palewise superimposed by the Coat of Arms of the United States in Proper colors.
A modified version of the Coat of Arms of the United States, located on the obverse of the Great Seal, authenticates our country's unity and our stand on defending the freedoms of the Homeland. The American eagle is also a symbol of strength and vigilance. The two stars represent the Adjutant General, the command level in each State to which these units report. The ten spears represent the Weapons of Mass Destruction Civil Support Teams (WMD CST) located in the ten response regions of the United States. The spears also represent the organization's heightened military readiness posture and that they are the initial military response to any WMD attacks as each WMD CST is the first unit sent to assess the situation, provide advice and support to civil authorities. The azure field represents the unit's ability to conduct continuous day and night operations and the red border signifies the resolve to protect and save lives. The total design signifies the importance of the Teams' mission to the peace and security in defense of our country.
The shoulder sleeve insignia was approved on 4 September 2007. (TIOH Drawing Number A-1-939)
