THE VOICE OF THE SAINTS.
Orange and white are the colors for the Signal Corps. The design, taken from the badge of the former 4th Signal Company, symbolizes the battalion's functions.
The lion is taken from the arms of Normandy. The heraldic representation of the spearhead held aloft is a reference to the battalion's participation in the invasion of Normandy.
The coat of arms was approved on 5 January 1959. It was amended to correct the blazon of the shield on 21 June 1968. The insignia was amended on 24 February 2004, to correct the blazon of the shield and crest.
