It is estimated by the Department of Defense that 65,034 Puerto Ricans served in the U.S. military during World War II. Soldiers from the island, serving in the 65th Infantry Regiment, participated in combat in the European Theater – in Germany and Central Europe. Those who resided in the mainland of the United States were assigned to regular units of the military and served either in the European or Pacific theaters of the war. Some families had multiple members join the Armed Forces. Seven brothers of the Medina family known as "The Fighting Medinas", fought in the war. They came from Río Grande, Puerto Rico and Brooklyn, New York. In some cases Puerto Ricans were subject to the racial discrimination which at that time was widespread in the United States.
