The M3 Hull served in many front line tanks as the Americans found it useful, this hull went on to be used up until 1942 in which the M4 Sherman was made and can be seen in all Sherman tanks. The M3 hull gave the T40 a lower profile in which was useful in battlefield situations. Three double-wheeled bogies were situated on either side of the hull.
