On a Silver color metal and enamel device 1 1/4 inches (3.18 cm) in height overall consisting of a Greek style shield emblazoned: Sable, a lion sejant affronté Argent, surrounded by a bordure of the like charged with five billets arched clockwise from chief Azure, Tenné, Gules, Vert and Celeste. Arched beneath the shield a Black scroll inscribed "DUCO UNDIQUE" in Silver metal letters.
The lion represents the Spartan leader Leonidas. The bordure with five billets, each color representing the branches that make up the Special Troops Battalion: Celeste (light blue) is for Military Intelligence, Gules (scarlet) for Engineers, Azure (blue) for Chemical Corps, Vert (green) for Military Police and Tenné (orange) for Signal Corps. The arrangement of the colors on the bordure with five billets alludes to the actions of the Spartan troops that retrieved and surrounded their leader (Leonidas) who had fallen during the Battle of Thermopylae from which the unit is named. The round shield is a representation of a Greek shield used at that time, which supports the symbolism of defending their leader in battle.
The distinctive unit insignia was approved on 31 October 2005. Coat of Arms
