The M4 Sherman tank was an American tank. It uses a 75 milllimeter round and has a top speed of about 25 mph. In terms of armor and firepower, it was inferior to the Tiger and Panzer Tanks, even though the Tiger was almost twice weight of the Sherman, it was about as fast as it. It, however, was a cheap and easy tank to make, and there was 50,000 Tanks made. In the movie, several Sherman Tanks were seen in D-Day on Omaha Beach, and one is seen at the Battle of Ramelle, when all the Tigers and Panzers are gone.
