Despite the efforts, only two Fiat 2000s were completed and production was permanently halted on November 4, 1918. It is known that at least one of the two wagons, prototype number 2, was taken to the Piave River in the spring of 1918 however there are no records of its wartime use
By the end of the war, a new direction had emerged thanks to a contract between Fiat and Renault that led to the production of Fiat 3000 light tanks (derived from the Renault FT).
The fact remains that at least one of the tanks was then transported to Libya, an Italian colony, where in the early years it formed part of the Autonomous Assault Tank Battery.
A 1924 Army inventory still testifies to the operation of only one Fiat 2000 so it appears that example No. 1 was scrapped or otherwise lost.
The last Fiat, after being modified in the mid-1930s and probably for propaganda reasons, disappears forever at the beginning of World War II, probably demolished.
