Scarlet and white are the branch colors of the Engineer Corps. The castle tower, a symbol of fortification and strength, is reminiscent of the Engineer Corps Branch insignia. The poleaxes symbolize the unit's mission of combat readiness and construction of bridges and forts. The fireball characterizes the military engineer's mission to handle explosives and mines. The four flames, pointing to the major geographical directions, emphasize the capacity of the Engineers to mobilize quickly, if needed, to all points of the globe. The canton, an allusion to the Confederate flag, honors the unit's campaign participation credits for Confederate service in the Civil War; the fleur-de-lis commemorates World War I and World War II service in Northern Europe and France.
The crest is that of the Virginia Army National Guard.
The coat of arms was approved effective 1 July 1986.
