Description
On a white square each side 2 inches (5.08cm) in width overall and with one angle up, four orange barbed lightning flashes arranged per cross and surmounted by a scarlet saltire all within a 1/8 inch (.32cm) orange border.

Symbolism
Orange and white are the branch colors of the Signal Corps. The red saltire is adapted from the Alabama State flag and refers to the unit's location. The radiating lightning flashes and arrowheads symbolize the command control, training and logistic support provided by the unit. The lightning flashes also refer to speed and communications. The shape of the insignia alludes to an early radio antenna.

Background
The shoulder sleeve insignia was originally approved for the 142d Signal Brigade on 16 Aug 1978. It was amended to reflect a change in the size of the insignia on 13 Apr 1979.
