The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Major of Artillery A. Joseph Marzac, French Army, for exceptionally meritorious and distinguished service in a position of great responsibility to the Government of the United States, during World War I. In Command of the Aerial Gunnery School at Cazeaux, Major Marzac displayed exceptional zeal and technical knowledge, combined with keen interest in the training of American students detailed to this school. He enabled them to secure training which rendered them markedly efficient at the front, thus rendering most valuable services to the American Expeditionary Forces.
