 The "L3 cc" anti-tank ("controcarro") was an L3 with a Solothurn 20 mm anti-tank rifle mounted in place of its normal machine gun armament.Only a few were so modified, and they saw action only in North Africa.The Solothurn rifle could penetrate up to 18 mm of armor at 300 m (328 yards) which was effective against lightly armoured vehicles.
