The Military Intelligence Service (Japanese: アメリカ陸軍情報部, America Rikugun Jōhōbu) was a World War II U.S. military unit consisting of two branches, the Japanese American unit (described here) and the German-Austrian unit based at Camp Ritchie, best known as the "Ritchie Boys". The unit described here was primarily composed of Nisei (second-generation Japanese Americans) who were trained as linguists. Graduates of the MIS language school (MISLS) were attached to other military units to provide translation, interpretation, and interrogation services.
"President Harry Truman called the Japanese Americans in the Military Intelligence Service (M.I.S.) the 'human secret weapon for the U.S. Armed Forces' against the Japanese in the Pacific. Major General Charles Willoughby said, 'The Nisei shortened the Pacific War by two years and saved possibly a million American lives.'"
They served with the United States Army, Navy, and Marine Corps, as well as with British, Australian, New Zealand, Canadian, Chinese, and Indian combat units fighting the Japanese.
General Hayes Adlai Kroner was Chief of MIS at the War Department for most of the War.
