Crimson and yellow are the colors associated with the Ordnance Corps, the original organization. The pile is used to simulate a pennon of honor, the four points "torn in battle" alluding to the original battalion's four battle honors of World War II; the two crimson bars referring to the two Meritorious Unit Streamers also awarded to that organization. The six blue fleurs-de-lis and two bars on yellow are the coats of arms in reversed colors of the 26th Division Quartermaster Train and subsequently the 101st Quartermaster Regiment, from which the original battalion was descended. The fleurs-de-lis represent the six World War I battle honors to which the unit was entitled.
The coat of arms was originally approved for 726th Ordnance Battalion on 6 Jun 1955. It was amended to correct the Latin form of the motto on 16 Jan 1956. On 30 Dec 1964 it was redesignated for the 726th Maintenance Battalion. The coat of arms was redesignated for the 726th Support Battalion on 10 Jun 1988. On 28 Oct 1997 the coat of arms was redesignated for the 726th Maintenance Battalion.
