When America entered World War 1 in April 1917 it was found wanting a working tank to cross the German trenches, which the British Tank Mark 1 had the previous year. Both nations joined a committee whilst in France and the design for the Liberty Tank aka Mark VIII International Tank. It had a similar layout and appearance to that of British Tanks, but with many improvements including:
Internal bulkheads separating the crew from the engine (protecting crew from fumes)
Amour thickness increased
Command and driver were stationed in a new superstructure on top of the tank
Some Liberty Tanks were built and one shipped to France, however with the signing of the Armistice, American Tank Corps were disbanded.
