Shield
Orange and white are the colors for the Signal Corps. The unit's World War II European campaign honors are symbolized by the fleurs-de-lis. The battalion's historic affiliation with a telephone company and the signal construction mission are depicted by the telephone pole, which also represents the organization's headquarters at Maryland, a state noted as the home of the first telegraph line.
Crest
The colors orange and white are traditionally associated with the Signal branch. The bear's head and two fleurs-de-lis refer to World War II campaigns in Central Europe, Northern France and Normandy. The wavy bend refers to the Rhineland and is taken from heraldic symbolism used in the region. The lightning flashes represent the signal mission and communication expertise. Gold denotes excellence, white signifies high ideals.
The coat of arm was originally approved for the 302 Signal Battalion, Army Reserve on 18 March 1955. It was amended on 5 September 2003, to delete the Army Reserve crest and add a new crest, for the Regular Army unit.
