WWII from the POV of a tank crew strikes me as a good premise for a movie. Maybe one of the men could be a little odd, and have visions he doesn't talk about of a ghostly horseman.
We recently had Fury -- it had preposterosity in common with Haunted Tank!
I'd not heard of that one; it sounds very like a Haunted Tank film. Wikipedia indicates it made a profit, and was less expensive to make than many superhero films.
Sgt. Rock-ish films might include A Walk in the Sun (1945) and The Big Red One (1980), but I've only seen portions of both.
