Little willie was just a prototype tank and only 1 was ever made. It was never intended to be used as a proper fighting machine, rather as a concept for what a tank could look like
The manufacturers of the Fiat 2000 only managed to complete 2 tanks before the war ended, and the tanks never saw any action.
Also, the quiz should accept just "A7V" as an answer, because that was it's official name. Sturmpanzerwagen isn't a part of it's name and it was used by the german soldiers just because it's easier to say "Armored assault vehicle" than to memorize the actual name
