Shield
The Regiment was organized in 1917 at Syracuse, New York, by drafts of personnel from the 23d Infantry. The shield is white and blue for Infantry. The device of Syracuse is a dolphin. The parentage of the Regiment is indicated in the canton. The 23d took over Alaska in 1867 and this is commemorated by the crest of that Regiment which is an eagle, the new owner America, upon a plate which is upon the head of a bear, the old owner Russia, the story being that the old owner gave a feast to the new owner when the country changed hands. The 50th's overseas service in World War I was in the Army of Occupation in the Rhine country indicated by the pale with wavy edges. It had been under orders for Silesia at the time of the Armistice.
