The Allied Translator and Interpreter Section (ATIS), also known as the Allied Translator and Interpreter Service or Allied Translator and Intelligence Service, was a joint Australian/American World War II intelligence agency which served as a centralized allied intelligence unit for the translation of intercepted Japanese communications, interrogations and negotiations in the Pacific Theater of Operations between September 1942 and December 1945. During the last few months of operation ATIS primarily focused on investigation of Japanese war crimes. The section was officially disbanded on April 30, 1946.
