A silver color metal and enamel device 1 1/8 inches (2.86cm) in width consisting of a silver tower between two silver towers masoned and detailed black, superimposed in base by a green triangle charged with a silver lion rampant charged on the shoulder with a black star, all enclosed at bottom by an oriental blue scroll doubled and inscribed "DE COLLE" in silver.
Oriental blue and silver/silver gray are the colors traditionally used by Military Intelligence units. The tower, or fortification, symbolizes strength and defense. The green triangle suggests a hill and, together with the lion, represent the unit's location in Great Britain at Menwith Hill Station near Harrogate. The black star symbolizes the military presence in the United Kingdom. The multiple towers highlight the organization's mission as executive agent for The Joint Combined Operations and Installation at Menwith Hall Station. The motto "De Colle" (From the Hills) refers to the unit's location.
The distinctive unit insignia was approved on 17 Jul 1997.
