| Notes | The Italian army first saw the need for a medium tank in 1939 and Fiat came forward with what they called a break through tank and this went into production as the M11/39. This vehicle was similar to an assault gun in many ways, as the designers wanted a gun with limited traverse to be able to destroy targets and a revolving turret mounting two machine guns to deal with infantry. The first M11/39s where sent to Africa in 1940 and saw action against the British. The M11/39 was found wanting when faced with British heavy tanks such as the Matilda, but they were the only battle tanks available and suffered due to inadequate armour and mechanical failures. Surviving vehicles were withdrawn and replaced by the M13/40. |
