The service of the former organization, the 139th Infantry Regiment, is indicated by the colors white and blue which represent Infantry. The gray saltire represents service as Confederate troops during the Civil War. The castle alludes to the Portuguese "Tower and Sword" decoration awarded the battalion in World War I. The key for Normandy and the battle-axe for Central Europe represent the two terminal campaigns of the unit in World War II.
The crest is that of the North Carolina Army National Guard.
The coat of arms was originally approved for the 139th Infantry Regiment on 24 May 1956. It was rescinded (cancelled) on 23 March 1960. The insignia was reinstated and redesignated for the 139th Regiment with the blazon and symbolism revised on 30 April 1997.
