ShieldCrimson and light blue are colors traditionally associated with Maintenance organizations; the predecessor unit. The sunburst, suggested by the Philippine flag, refers to the predecessor organization's historical service in the Philippine Islands and the general area of the Pacific during World War II, and also to occupation duty in Korea. The arrowhead stands for the assault landings at Sanspor, New Guinea and Lingayen Gulf. The chequy alludes to the orderly performance of the unit's mission to provide field mission to contribute field support.
CrestThe sea lion, symbol of courage, is adapted from the Philippine Presidential flag. The kris is a traditional weapon from the Western Pacific area and refers to the unit's war service there. The daggers also represent two campaign participation credits earned in World War II. The red collar symbolizes the organization's Meritorious Unit Commendation. Red, white (silver) and blue, represented by the handles of the daggers, blades and sea lion respectively, commemorate the Battalion's Philippine Presidential Unit Citation.
The coat of arms was originally approved for the 706th Maintenance Battalion on 20 May 1968. It was amended to clarify the blazon and symbolism of the design on 12 November 1981. It was redesignated for the 706th Support Battalion with the blazon and symbolism revised effective 17 April 1992. The insignia was amended to include a crest on 5 February 1992.
