The 100th Battalion, 442nd Infantry is the only remaining combat arms unit in the U.S. Army Reserve, the other units in the Army Reserve being combat support or combat service support.^[1] The unit combines the identities of two World War II Japanese-American units, the 100th Infantry Battalion and the 442nd Regimental Combat Team. 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.

Historically, the unit is referred to as the "Purple Heart Battalion", with the motto "Go For Broke". One of the most famous members of this unit was U.S. Senator Daniel Inouye who was part of the 442nd Regimental Combat Team. He lost his arm from wounds sustained in combat.

[edit] History of the 100th Battalion

The 100th Infantry Battalion (Separate)—known as the "One-Puka-Puka" (Puka means "hole" in Hawaiian) -- was activated on June 12, 1942, a force of over 1,400 predominantly Nisei (Second Generation Americans of Japanese Ancestry), led by a handful of "haole" (Caucasian) officers. The troops were from the Territory of Hawaii, which led to many pidgin phrases becoming common in the Battalion and in the subsequently-formed 442nd Regimental Combat Team.

Currently serving Nisei had been removed from service in Hawaiian territorial and police units following the Pearl Harbor attack, but the Hawaiian Military Governor Lieutenant General Delos C. Emmons chose not to use his option of deporting those of Japanese descent for internment on the mainland. Soon, he had been petitioned by the Nisei eager to return to military service to defend their homeland. This eventually resulted in the formation of the 100th Battalion. The battalion commander and some of the company-grade officers were Caucasian; most of its officers and enlisted men were Nisei, but the unit included men of Korean descent as well.

The unit number was an indication of the Army's recently formulated plan for a modern organization for the Combat Arms. Under normal pre-war Army procedures, all Infantry battalions were organic to the Regiment they were a part of, and were known as, for instance, "1st Battalion, 5th Regiment." With the new system of organization, the Infantry Regiment was reorganized as a Headquarters with no Organic battalions, but with three Separate Battalions attached. The Headquarters was organized into three Combat Commands that could be dispatched on separate combat actions with units that were attached. One Infantry Battalion would be assigned to a Combat Command, with attachments from the higher headquarters reserve.

After training at Camp McCoy, Wisconsin, and Camp Shelby, Mississippi, the battalion was ready to deploy, but was refused by General Dwight D. Eisenhower. General Mark Clark, commanding the Fifth Army, accepted the offer, and the One-Puka-Puka deployed to the Mediterranean in August 1943.

Fifth Army attached the battalion to the 34th Infantry Division. The unit entered combat on September 27, 1943, near Salerno in Southern Italy. The battalion fought well and took heavy casualties, leading Clark to tell the Army "Send me all you got!"

Impressed with the valor of the Nisei (including six awards of the Distinguished Service Cross in the first eight weeks of combat), the War Department recommended that more Nisei volunteers be sought, from both Hawaii and the mainland relocation camps, to form the 442nd Regimental Combat Team (RCT), activated on February 1, 1943, also to be sent to Italy. The 100th and 442nd were assigned to fight alongside each other.

The 100th Battalion fought at Cassino in January, 1944, and later accompanied the 34th Infantry Division to Anzio. In May and June, 1944 the battalion, joined by the 442d RCT, helped break out from Anzio and push the Germans north of Rome. The battalion was awarded the Distinguished Unit Citation (DUC) [later redesignated the Presidential Unit Citation (PUC)] for its actions on June 26–27.

On August 10, 1944, the 100th Battalion formally became part of the 442d RCT, for the final nine months of the War in Europe. The 442d RCT was demobilized and deactivated in August, 1946, leaving their honors, lineage and traditions to the 100th Battalion from which many had been inherited two years before. This lineage and these honors continue to be preserved by the 100th Battalion, 442d Infantry (US Army Reserve).

A nationwide campaign to urge the U.S. Postal Service to issue a commemorative postage stamp to honor the contributions of the Japanese American soldiers of World War II was begun in 2006 in California.
