My father, Robert H. Traina (1914-1968), U.S. Army. Photo taken in 1941, probably at Fort Dix, New Jersey. He was drafted in April of that year. Later he entered officer candidate school and served in the Coast Artillery Corps in Hawaii.
He is carrying a Springfield rifle and looks to be wearing a cavalryman's lace-up riding breeches. Part of his kit would be the WWI British-style helmet and a large shoulder bag for his gas mask.
