Once described as the worst tank that ever won a war it was built in the States by car factories, railway works and vast purpose-built factories. The M4 Sherman saw service in all theatres of the Second World War as well as in later conflicts in Korea and Israel. It came in many variants. The British gave it a bigger gun, they made 'funnies' that could throw flames or swim ashore and wade rivers or ditches, they were used to lay bridges, clear minefields and even launch rockets. Many Sherman's were sold overseas to countries such as Uganda, Italy, Paraguay, Argentina and Mexico.
