KNOWLEDGE, UNITY, SPEED.
Orange and white are the colors traditionally associated with Signal units. The sea-lion and the eight rays of the sun are taken from the Seal of the President of the Philippines; they commemorate the action for which the Battalion received the Philippine Presidential Unit Citation and also refer to participation in four campaigns in the Philippine area during World War II. The torch grasped by the sea-lion represents knowledge, the annulet symbolizes unity and the lightning flashes, speed. The blue disc represents Lake Ontario, which is in the vicinity of the Battalion's previous home area in New York.
The crest is that of the United States Army Reserve.
The coat of arms was approved effective 16 October 2007.
