A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a bottony cross parted quarterly red and white with a pair of green scale pans suspended from a beam arced across the top and surmounting the cross with the point up, a blue arrowhead bearing a gold fleur-de-lis, all above a green scroll arced from the outer lateral arms and inscribed "MARYLAND'S FINEST" in gold letters, all open areas within the design of brick red.
Green and gold (yellow) are the colors used for the Military Police Corps and the cross indicates the Maryland Army National Guard. The scale pans connote equal justice in lawful processes in the overall mission of the organization. The fleur-de-lis refers to France and the central European areas where the unit participated in two campaigns during WWI and four campaigns during WWII. The arrowhead denotes the assault landing at Normandy during the latter war and blue refers to the award of the Presidential Unit Citation and red and green to the French Croix de Guerre. The brick red color, suggested by the organization, reflects assigned units.
The distinctive unit insignia was approved on 15 February 1974.
