High Quality Content by WIKIPEDIA articles! The Semovente 75/18 was an Italian self-propelled gun of the Second World War. It was built by mounting the 75 mm Obice da 75/18 modello 34 mountain gun on the chassis of a M13/40 or M14/41 tank. The first 60 were built using the M13/40 chassis and a subsequent 162 were built on the M14/41 chassis from 1941 onwards. The Semovente 75/18 was intended to be an interim vehicle until the heavier P40 tank could be available.
