Symbolism
Shield:
The shield is blue for Infantry, the original designation of the unit.
The gold bend is taken from the arms of Alsace; the 349th Infantry served as a unit of the 88th Division during World War I, where the division wore the blue quatrefoil.
The fleur-de-lis indicates the regiment's baptism of fire in France.
The chief is made white, so as not to have a blue quatrefoil on a blue field.
Crest: The crest is that of the U.S. Army Reserve.
