Many Hawaii residents served in the 442nd Regimental Combat Team, a U.S. Army infantry regiment. The regiment was composed almost entirely of American soldiers of Japanese ancestry. The regiment fought primarily in Italy, southern France and Germany. The 442nd Regiment was the most decorated unit for its size and length of service in American history. Its 4,000 members had to be replaced nearly 2.5 times due to casualties. In total, about 14,000 men served, earning 9,486 Purple Hearts. The unit was awarded eight Presidential Unit Citations (five in one month). Twenty-one of its members, including Hawaii U.S. Senator Daniel Inouye, were awarded Medals of Honor. Its motto was "Go for Broke".
