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

In practice tanks have a low enough center of gravity that you can't actually do that, you're going to need to lift it. You might also need flight or increased SM, I'm not sure how far you need to lift the side of a tank before it actually falls over.

The super ST rules being what they are, it's not going to make a lot of difference -- super ST 10 (+100) is likely not enough, super ST 12 (+200) is probably enough, super ST 14 (+450) is definitely enough.
