The magical turret probably has a lot less metal but may have some other armor technologies or metals that compensate. I don’t know if the barrel of the gun was included in the weight but they did say that the gun was half the weight, maybe it is made of titanium?
What happened to the Bradleys? That 3 round burst thing of 30mm is very effective.
I dont think we need a smaller MBT or a larger BFV. I am not liking this model.
