Ligero Trubia tank

The Trubia A4 was a Spanish experimental light tank developed during the 1920s by the Fábrica de Armas de Trubia. Based on experience gained with the Renault FT during the Rif War, it was intended to provide the Spanish Army with the first domestically produced tank. Four prototypes were built between 1926 and 1934. Although several innovative features were introduced, it never entered production. The surviving vehicles saw limited service during the Spanish Civil War.
