The shield is in the colors of the Signal Corps. The bonfire and curling smoke symbolize one of the primitive forms of signaling.
The millrind, a symbol of strength, represents the invaluable support and skill in communications which the 53d Signal Battalion contributed to the Allied assaults first in Algeria, later in other actions in North Africa and Italy during World War II. The flashes denote skill in modern communications and speedy response to mission requirements. Participation in campaigns in Vietnam is recalled by the annulet of bamboo, signifying also unity and cooperative action. Scarlet and gold denote respectively courage and excellence.
