"100th Infantry Camp McCoy, 1942-43" 第100歩兵大隊 was a unit within the U. S. Army's 34th Infantry Division during World War II. The primarily Nisei battalion was composed largely of former members of the Hawaii Army National Guard. Upon its activation, the 100th saw heavy combat during World War II before and after combining with the 442nd Infantry Regiment, another mostly Nisei military unit, into a single fighting combat team. Historically, the unit is referred to as the "Purple Heart Battalion", with the motto "Remember Pearl Harbor". -Wikipedia
