Shield
The shield is blue for Infantry; blue is also the color of the South Carolina State flag. The palmetto tree is from the State flag of South Carolina, the allocation of the 327th Infantry. The red bend is taken from the arms of the ancient province of Lorraine, and the fleurs-de-lis indicate the three major operations in which the organization participated during World War I.
Crest
The nebuly delineation, a heraldic simulation for clouds, represents the descent of the 327th Infantry from the 327th Glider Infantry, an organic element of the 101st Airborne Division during World War II. The two spearheads surmounting the nebuly pierced disc indicate the combat glider landings and aggressive action of the unit in Normandy and the Rhineland. The oak leaves and acorn connote Bastogne in the Ardennes. The pierced white disc further alludes to the snow and encircled Bastogne during the Battle of the Bulge for which the organization was awarded the Distinguished Unit Citation. Additionally, the colors red and green refer to the foreign decorations French Croix de Guerre with Palm, World War II, and the Belgian Croix de Guerre, 1940.
