Roger Obata and Robert Oikawa from S-20 were posted respectively in February and March 1946 to the US Army’s Pacific Military Intelligence Research Section (PACMIRS) in Washington, D.C. (Oki, 1967 and Ito, 1984, p. 251). PACMIRS was established in September 1944 to exploit captured Japanese records (Bradsher, 2014).
Personnel needed to screen, scan and catalogue captured documents sent back from the Pacific such as manuals and technical journals (Lamarsh, 1967). Obata translated technical documents. Robert Oikawa was recognized by his commanding officer for his expertise on translating Japanese ordnance documents (Ito, 1984, p. 254).
