A medium tank employed by the US army during WWII, was generally effective in an infantry support role, but lacked the necessary armor and armament to combat the more advanced german Tiger and Panther tanks. The tank relied on numbers and co-operation with dedicated tank destroyers to combat the superior german armor.
The tank was easilty produced, reliable, a valid engine, it was equipped with a 76mm gun, and adequate armor. It was an adequate tank, but suffered great casualties.
They were prone to combustion when attacked by the high velocity 75mm and 88mm guns the Germans employed, nick named 'Ronsons' by the British for this reason.
The standard medium tank of the allies was the Sherman tank
