The tank design was unusual in that the larger caliber gun was in a sponson mounting, with limited traverse, in the hull and the small turret had the 37mm gun. A small cupola on top of the turret held a machine gun giving the effect of one turret on top of another.
The British ordered the M3 when they were refused permission to have their tank designs made by the American amories. They were unhappy with the tall profile and had their own turret fitted - lower in profile with a bustle at the back for the radio set. This received the name "(General) Grant", unaltered M3's were called "General Lee", or usually just Grant and Lee
The design of the M3 hull was adapted by the Canadians to develop their Ram tank - a conventionally turreted tank. The hull was also used for self propelled artillery.
The M3 was withdrawn when the M4 Sherman became available.
