The Cassette’s Driven Motor housing is somehow completely omitted ( it should be very important as an effort to avoid the potential for “Driver, Engine” shots to the lower LFP magically bypassing the autoloader with no damage done.) from the autoloader module entirely, since it takes up the space under the Turret since the structural guide for the Cassette doesn’t sit on the floor of the Hull. The M1’s for example also get a Hydraulic accumulator in the fighting compartment instead of the actual pump in the engine compartment where it should be.
They could similarly for example give the M1’s the 120mm Meggit autoloader that was trialed in order to make things fairer and have more tanks equipt with an autoloader.
