[TDR]

as a normal case most Grant and Lee tanks did not have the hull mounted machine guns, .30 (2)BMG as per game.
Normal lay out was 2 .30 Mgs, one co axial and the other for the commander.
The Lee tanks also was not supplied with a turret cupola as per US vehicles

It may not be worth making this change as well as the point Aust Lee tanks were petrol and hence were disposed of after the war.
