The two divisions of the shield are used to denote service during World Wars I and II. The fleurs-de-lis symbolize the original organization's action during World War I in Lorraine, Saint Mihiel and Meuse-Argonne, France. The rampant lion, suggested by the coat of arms of Belgium and the Netherlands, alludes to the former organization's drive during World War II to stem the invading enemy; and the wavy bar alludes to the wavy bend on the arms of Rhineland signifying the sweep through that province during the same campaign. The engrailed border represents a parachute and symbolizes that unit's service with the 82d Airborne Division.
The griffin (a composite of eagle and lion) symbolizes the coordinated campaign of the Allies. The five hills represent the liberation of the city of Nijmegen. The roundel, simulating a wheel, alludes to the Quartermaster and Transportation Corps. The parachute with its nine cords refers to the nine campaigns in which the parent unit participated during World Wars I and II. The colors commemorate the decorations awarded the 407th: red and green for the Belgian Fourragere, red for the Meritorious Unit Commendation and orange for the Netherlands Lanyard.
The coat of arms was originally authorized for the 407th Supply and Transportation Battalion on 5 May 1965. It was amended to correct the designation of the Battalion on 16 July 1965. It was redesignated for the 407th Supply and Service Battalion on 21 September 1974. The insignia was redesignated for the 407th Supply and Transport Battalion on 21 September 1987. It was redesignated for the 407th Support Battalion effective 16 April 1994, with blazon and symbolism revised.
