TEAMWORK STRENGTH SPEED
The unicorn, the heraldic animal with the body and head of a horse and the legs and feet of a deer, is strong as a horse and swift as a deer. The two unicorns symbolize the teamwork, strength and speed of the 43d Signal Battalion and its heavy construction duties. Since the unit was originally activated at Fort Crowder, Missouri, the horses further allude to the early history of the area when the starting points of the Santa Fe Trail and the Pony Express were in Missouri. The white chevron represents the lights and beacons of the Signal Corps. The Far Eastern structure, and the fountain, a conventional heraldic representation of water, refer to the overseas service, the buildings and rice paddies of Vietnam. The lightning flashes are symbolic of Communications and the four jagged points of the flashes represent the four battle honors of Ardennes-Alsace, Central Europe, Northern France and the Rhineland. The colors black and white refer to the day and night vigilance of the unit, while orange is a color of the Signal Corps.
The towers, recalling medieval signal towers, symbolize World War II service in the Rhineland and Central Europe, while the fleur-de-lis recalls participation in campaigns in Northern France and Ardennes-Alsace. The many campaigns the unit saw during the Vietnam Conflict are represented by the annulet of bamboo. The unit's most recent service in the Defense of Saudi Arabia and Kuwait is recalled by the two scimitars. Blue denotes integrity and worldwide service. Scarlet and gold signify courage and excellence respectively.
