Japanese Army Type 89 I-Go medium tank (opening-stock lower bound)

A conservative one-tank category lower bound based on the Japanese Army's official Type 89 history: the Army standardized the type in October 1929 as its first main tank, and the source records Army operations in 1931 and 1932. It is not a claim of total Type 89 production or a reconstruction of Japanese Army tank strength. The explicit reviewed mapping is armor-light, the scenario catalogue's available armoured unit category.
