Shield
Orange and white are used for the Signal Corps. The fess crossing the field is used to represent a wire or cable and the black circle, the soft iron diagram in telegraphic equipment. The lightning flashes allude to the currents which cause the diaphragm to vibrate and thus transmit sound. The black circle thus symbolizes a sounding board from all types of signal apparatus and its construction and maintenance. The fleur-de-lis signifies combat service in Europe during World War II.
Crest
The eagle embodies strength and vigilance. It represents the organization's service in Europe in World War II and in Vietnam. Gold is emblematic of honor and high achievement. The red reflects valor and is the color of the Meritorious Unit Commendation; two were awarded to the unit for honors earned in Vietnam. The lightning flash highlights electronic capabilities and quick response, while the palm refers to the tropical nature of Vietnam.
