I’m not up to date on WWI tanks but this is defiantly a British male variant owing to the guns as the female variant had machine guns, it could be a MkV though I’m not sure what I can tell you is seeing one run is very rare much rarer that the Tiger especially if it had the original engine un fortunately the one used in the film is another Hollywood fiction piece that had no reality.

The British invented the tank and in the 30’s France and Russia where world leaders of tank development.
