WARRIORS SUPPORT WARRIORS.
Scarlet is one of the colors traditionally used by Support units and the color also denotes valor and sacrifice. The chevron configuration is a symbol for support and emphasizes the support mission to the warfighter. The castle, symbol of defense and strength, signifies the unit's ties with the Engineer Branch. The following branches are also associated with the Battalion: Quartermaster Corps represented with the blue color and key; Maintenance with the wrench; Ordnance with the flaming bomb; and Transportation with the wheel. The golden sunburst is adapted from the 41st Division and recalls the Battalion's heritage.
The crest is that of the North Dakota Army National Guard.
The coat of arms was approved effective 1 September 2008.
