Shield
Orange and white are colors traditionally associated with the Signal Corps. The six embattlements of the chief refer to the six World War II campaigns in which the former Battalion participated. The star and the fleur-de-lis represent that unit's two decorations the Meritorious Unit Commendation and the Croix de Guerre. The chevron denotes support and the bugle horn the martial spirit and mission of the unit.
The coat of arms was originally approved for the 147th Signal Battalion on 5 June 1964. It was redesignated for the 134th Signal Battalion with the blazon and symbolism revised on 15 May 1991.
