The 100th Infantry Battalion was a unit within the US 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. The 100th exists today as the only remaining combat arms unit in the United States Army Reserve, the other units all being combat support or combat service support.[2] Based at Fort Shafter, Honolulu, Hawaii, the 100th Battalion has reservists from Hawaii, American Samoa, Guam and Saipan, and has been activated and deployed to Iraq and Kuwait. Historically, the unit is referred to as the "Purple Heart Battalion", with the motto "Remember Pearl Harbor".
