The shield is blue to indicate that the organization served with an Infantry Division and also that the majority of the personnel were drawn from the Infantry. The gold barrulets represent that portion of the personnel drawn from the Cavalry. The six fleurs-de-lis symbolize the operations in which the organization participated during the World War I.
The crest is that of the Massachusetts Army National Guard.
The coat of arms was originally approved for the 26th Division Quartermaster Train on 16 July 1927. It was amended to correct the motto on 4 December 1928. On 29 December 1936, the coat of arms was approved and reassigned for the 101st Quartermaster Regiment. It was authorized for the 26th Supply and Transport Battalion on 23 December 1964. As a result of the reorganization of Massachusetts, Connecticut and Vermont ARNG units, the insignia was cancelled on 16 February 1988. The coat of arms was reinstated and redesignated effective 1 September 1995, for the 101st Quartermaster Battalion. It was redesignated for the 126th Support Battalion on 23 February 2007.
