FIDELITY AND SERVICE.
The blue of the shield is for Infantry. The bend is taken from the arms of Lorraine where the organization saw service during the World War, but the tincture has been changed. The Iowa State Flag as approved in 1921, is blue, white and red; accordingly the shield is of similar tinctures. The ear of corn alludes to "The Corn Song," the soldier's marching song of Iowa.
The crest is that of the U.S. Army Reserve.
The coat of arms was originally approved for the 350th Regiment Infantry, Organized Reserves on 27 Mar 1928. It was amended to withdraw "Organized Reserves" from the designation and delete the Organized Reserves' crest from the coat of arms for the 350th Infantry Regiment on 10 Feb 1954. The coat of arms was redesignated for the 350th Regiment on 5 May 1999.
