Old tank in world war 2
Pictured above is the turret of a M4 Sherman poking it's turret out of the watwe off the coast of Saipan, where it was sunk trying to come ashore on June 16th, 1944.
The American-built M4 Sherman was the most ubiquitous tank of the war, as far the Western allies were concerned. Entering service in 1942, it was used extensively by the British and Americans. With a crew of five, it mounted a 75mm gun, two . 30 caliber machine guns (one in the turret next the the main gun and the other in the assistant driver's seat) and usually a M2 Browning .
50 cal on the outside of the turret but sometimes this was a M1919. Automotively it was very reliable and capable of a speed of 24 mph (38 kph). The major drawback of the M4 Sherman was a tendency to catch fire when hit, mainly because some ammunition was stowed in the turret. Also it had weak armor and a gun which was incapable of penetrating most of the German tanks.
This would change during the war when different variants like the M4A2E8 "Easy Eight" and Sherman "Jumbo" were put into action with better guns and armor. Fun Fact: The German's nicknamed the M4 Sherman the "Ronson" after the popular lighter brand.
