Insignia Description
A Silver color metal and enamel device 1 1/8 inches (2.86 cm) in height overall, consisting of a shield blazoned: Per bend Azure (Oriental Blue) and quarterly Gules and Or, on a bend engrailed Argent a lightning bolt of the second and in sinister chief a wyvern's head of the fourth.

Symbolism
Oriental blue and silver gray are the colors associated with the Military Intelligence Corps. The wyvern's head has been adapted from the device of the 3d Infantry Division which this battalion supports. The wyvern is a heraldic creature known as a fearless guardian and thus symbolizes a major role of the intelligence mission. The lightning bolt on the engrailed bend alludes to the unit's special interest in communications of hostile and friendly forces as well as communications throughout the battalion. The scarlet and yellow quarters refer to the arms of Wurzburg, Germany, the unit's location and its place of activation.

History
The distinctive unit insignia was approved on 27 August 1981.
