The Lancia 3Ro was a heavy truck built by Lancia from 1933 to 1947 for military use by Italy. The truck was used as a troop transport, supply transport, fuel tanker, water tanker, mobile repair workshop, anti-aircraft gun, and self-propelled gun, and it was well-suited for desert warfare in North Africa during World War II. The truck was also used by the Wehrmacht after the Italian armistice in September 1943.
