The M3 Lee was a medium tank, used by both the U.S. and British forces (where it had the designation M3 Grant) and saw use in the battles of North Africa. It was quite unique in that it mounted a 75mm gun in the hull and a smaller 37mm gun in a small top turret above the superstructure.

The M3 Lee Expansion Pack gives players a tank with a very similar stat line to its successor, the M4A1 Sherman. It features with a good mix of Mobility, Initiative and Survivability, whilst the fixed main gun and lower Initiative results in a lower point cost making it a good choice for gamers on a budget.
