Crimson and yellow are the colors used for Ordnance. Buff is the color of the Quartermaster Corps and indicates the unit's origin and service as a Quartermaster company. The rayonné partition line signifies the intense fire power produced by the Ordnance material. The lion, suggested by the coat of arms of Normandy, commemorates the organization's special decoration for extraordinary heroism during the Normandy assault landing. The four divisions of the shield refer to the battalion's battle honors for service in Europe during World War II.
The crest is that of the Maryland Army National Guard.
