Four American servicemen pose together in field uniform during World War I, wearing the wool service shirts, breeches, wound puttees, and campaign hats typical of U.S. Army dress of the period. Photographs like this one, often taken informally among friends, offer a personal glimpse into the camaraderie shared by young Americans training for -- or serving in -- the First World War, whether stateside at installations such as Scott Field or overseas with the American Expeditionary Forces in France.
