Rep. John Boehner presents the Congressional Gold Medal to a representative of the 100th Infantry Battalion, Mitsuo Hamasu, during a ceremony Nov. 2, 2011, at the Capitol Visitors Center in Washington, D.C. The Congressional Gold Medal is awarded by the American Congress, and is the highest civilian award in the United States. The medal was awarded to Nisei Soldiers -- American sons of Japanese-born parents -- who fought in World War II. Those Soldiers fought as part of segregated, all Japanese-American units that included the 442nd Regimental Combat Team, the 100th Infantry Battalion and the Military Intelligence Service. The three units together were the most decorated units of that war.
