No .. first the army asks ... can you make a <50 ton tank .. if so how ?A more logical answer than any other but still as an engineer I will be skeptical. Lets see how this progresses. And RFI should atleast have the spec boundaries (e.g. weight<50 tonnes) etc.
If no one can make <50 ton tank . Then specifications will says <60/70 ton or whatever.
