The 64th Infantry Regiment was a Regular infantry regiment in the United States Army. Only active from 1917 to 1922, it was reconstituted in 1941 but was never officially reactivated and was disbanded in an inactive status in 1952.
World War I
The regiment was organized in 1917 from personnel of the 34th Infantry, which is shown on the canton. It was in the 7th Division, which operated in Lorraine in the area formerly in the domain of the ancient lords of Commercy, whose arms were blue and scattered with golden cross crosslets, pointed at the lower end. The shield is blue for infantry with one such cross crosslet. The crest is the thistle of Lorraine, one of the old emblems of that province and still existing in the arms of the city of Nancy.
