In Gurps, how powerful do you need to fight a tank?

With Flight or increased SM (possibly via Stretching), I think you could potentially get away with the ability to lift half the tank's weight, as it's still resting on one track while you're lifting it. A two-handed overhead lift (taking four seconds) lets you lift up to 8xBL, so you'd only need BL equal to 1/16th the tank's weight to be able to lift it up on its side, and once it's there anyone strong enough to lift it there in the first place can knock it the rest of the way down. Without Flight or Increased SM, you'd need to be able to lift it fast enough that it has enough momentum to keep going after you let go. I'm not really certain what that would be, but I'd be tempted to say having 1/4 BL would suffice. Or maybe you could treat it as needing to be able to throw half the tank's weight as high as its width? Throwing straight up halves Range IIRC, and something like the T-72A is around 4 yards wide, so you'd need to be be able to throw something half the tank's weight 8 yards to do it - or only 4 yards if you let the character get a "free" two yards to account for them being able to lift it around that high normally. How much ST that needs, I don't have time to calculate at the moment, but you could use B355.
