(c)2008 Given the number of technological advances made in the 20th century after the resurrection of Jesus Christ,...it only stands to reason that, in the 21st century, there will be even greater advances in all fields of science. This hovertank may not even carry an artillery gun,...but more likely a high energy lasergun. And rather than tons of armour weighing it down,....a lightweight carbon fiber and teflon shell all around. And no fossel fuel engine but a small nuclear reactor powerplant. It might not even have a crew on board but be totally automated. Can we be too far away from the age of the Terminator? :O)
