Heh, you'd think that before someone went to the trouble of buying millions of dollars worth of a property that they'd test it in the field before hand. Sad to say some troops probably lost their lives driving around in gas powered tank engines.
Chrysler's tank engines were turbine engines that had mega torque and hp. Those are basically what saved Chrysler back in then, the government bought up all those engines. Then they found out that having a gas powered tank was a bad idea because gasoline exploded easily so now all tank engines are diesel powered. Getting your hands on one of those would be next to impossible.
