 The U.S. military is this week commemorating a Japanese-American army unit that helped to liberate parts of Italy during World War II. As Villa Marks reports, many soldiers in the unit fought in Europe while family members were detained in the United States. Eighty years on from the liberation of the Tuscan town of Livorno, descendants of the all-Japanese U.S. Army unit known as Nisei are traveling there from states including California and Hawaii to pay their respects to those who fought against Nazi and Italian militants
