English: The Distinctive Unit Insignia of the Maryland Army National Guard Element, Joint Force Headquarters pays homage to two of Maryland’s most famous families, with the two quarters of the insignia’s shield, arranged catawampus (roughly the 4 o’clock and 10 o’clock positions) displaying the arms of the Calvert family and the other two featuring the arms of the Crossland family. Cecil Calvert, the 2nd Lord Baltimore, inherited the second coat of arms from his grandmother, Alicia, who was the wife of Leonard Calvert, father of George Calvert who was the 1st Lord Baltimore.

The coronet serving as a crest above the shield denotes that the fact that Calvert was an earl in Maryland despite being a lower-ranked baron in England. Flanking the shield are two figures representing the true backbone of Maryland during its founding, a plowman on the left symbolizing agriculture and ranching and a fisherman on the right as an emblem of Maryland’s seafaring industries.

Also called a unit crest, this Distinctive Unit Insignia (DUI) was originally designed and approved for the HQ and HQ Detachment and all non-color bearing units of the MD Army National Guard on 9 April 1971. It would subsequently be redesignated twice, once in October 1982 for the HQ, State Area Command of the Maryland Army National Guard and again exactly 21 years later in 2003 for the Army element of Joint Force HQ, Maryland National Guard.
