Orange and white are colors traditionally associated with Signal Corps. The wavy diagonal band, representing the Rhine River, refers to the Battalion's participation in campaigns in the Central European area. Blue and the patterned bands flanking the central band are taken from the Arms of Ardennes. The "potent" pattern also represents telegraph poles and refers to the unit's signal function.
During the Vietnam War the organization provided signal support, represented by the flash, to the I Field Force, Vietnam. The sword is from the shoulder sleeve insignia of the supported organization; it is also indicative of combat support and the award of the Vietnamese Cross of Gallantry to the organization. The bamboo also refers to South Vietnam and is divided into three segments to represent the three Meritorious Unit Awards to the organization while the leaves represent the thirteen campaigns in that country.
