Development of the previous generation medium tank lead to the development of the M3 medium tank. This is famously known as the M3 Lee which was named after general Lee, and M3 ‘Grant’ was named after general Grant. The Grant had a modified turret, compared to the M3 Lee. Both M3’s used the same armaments.
Continuing on from the previous generations saw the development of arguably the most iconic tank in the world: The M4 Sherman, named after General Sherman. This series was developed to be low cost, simple and effective. To begin with, the Sherman was still underdeveloped compared to other medium tanks at the time. However, over its lifetime, the M4 Sherman would be redeveloped and retrofitted to be one of finest tanks ever produced.
