The M4A3E8 Sherman is a variant of the M4 Sherman. The M4 Sherman, officially the Medium Tank, M4, was the primary battle used by the United States and the other Allies in World War II, and proved to be a reliable and highly mobile workhorse. Nonetheless, they were significantly weaker than Heavy tanks such as the Tiger I, accurately portrayed in the movie.
In the film Fury, the main tank, Fury, is an M4A3E8 Sherman, with "FURY" painted on the barrel of the main cannon.
