On a shield-shaped embroidered device 3 1/4 inches (8.26 cm) in height and 2 3/4 inches (6.99 cm) in width overall blazoned: Azure, a sword erect supporting a pair of scales Or, surmounted by a glory of six pommels Argent, bearing a mullet of the field, all entoured by a bordure Gules.
The shield-shaped patch reflects the nature of legal defense work. The sword supporting scales of justice represents the unit's mission to defend soldiers at courts-martial and separations boards; seeking justice for all soldiers. The sword also signifies that Trial Defense Service personnel are soldiers as well as lawyers. The glory, mullet, and the red border are adapted from the Department of the Army Staff Support patch previously authorized for wear by the Trial Defense Service, and provides a historical link to its organizational heritage.
The shoulder sleeve insignia was approved on 17 August 2006. It was amended to correct the height on 21 September 2012. (TIOH Drawing Number A-1-896)
