The tank has a few names but not quite sure what to call it... it can be called either the Mark VIII tank, The International, or the Liberty. It was a US/UK tank prototype designed near the end of WW1 they never saw use.

It's actually an entirely fictional vehicle that takes some inspiration from the Mark VIII.
