Shield
The design of the shield is similar to that of the former 164th Infantry Regiment, parent organization of the Battalion. The colors of the field and the castle have been reversed for a difference. The shield is scarlet for the Corps of Engineers. The Spanish castle, taken from the Spanish Campaign Medal, represents Spanish War service. The Philippine Insurrection service is indicated by the three mullets from the Philippine Island flag. The sun, taken from the 41st Division shoulder sleeve insignia, symbolizes World War I service with that Division.
