Also, using the MBT in VE2 as your base tank (yes. it's supposed to be a M1A3) will not give you good numbers for a Russian T-72. The M1 is 33% heavier than a T-72 and proportionately bulkier around the turret and perhaps generally.

Thanks for the heads up. So just look up the armor's surface area and use that?

Fortunately, RAP appears to have turned out to be a less revolutionary technology on actual battlefields than it was in the conventional wisdom of the mid-90s.

Largely because of tandem-charge warheads quickly coming onto their own, though the current situation in Ukraine indicates that some serious corruption gutted the ERA on the tanks.

Still, it shouldn't be almost 18 metric tons for 'heavy' ERA on just the turret of the tank if what I currently checking with is any indication.
