The colors, white and teal blue, are symbolic of the battalion's former status as an unassigned-to-branch unit. The battalion's war service as a Signal unit is shown by the colors of the fox's mask and background. Intelligence functions of the unit are represented by the censor's stamp on the fox's mask. The key is for the first battle honor (Normandy) of World War II and also alludes to Signal and Intelligence Battalions. The lightning flashes symbolize radio reconnaissance and the five charges are for the five battle honors of the unit.
The fleur-de-lis represents campaign participation in Europe. The colors blue and white suggest the unit's former designation as branch unassigned. The outer petals of the fleur-de-lis, suggestive of electronic flashes, reflect the unit's service in Communications Reconnaissance. The bar on the crosspiece is divided into five segments representing participation in five campaigns in Europe during World War II and is orange and white referring to the unit's original designation as Signal Service. The bayonet suggests the Army's offensive spirit and reflects the unit's association with U.S. Army, Europe.
