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

Is the Raufoss statted out as SAP - AD (1) - or APHEX - AD (2) - in GURPS? If the latter, that might let it kill the crew (with AP, you've got to get a lucky shot where Hitting the Wrong Target results in a crew member getting got, but an internal explosion is going to be a lot more effective; technically against DR 60 that 13d+1(2) pi is going to result in "only" around 5d-1(2) pi getting through, which I think Level III armor might be able to at least drop below the Major Wound threshold, and I'm fairly confident Level IV armor would stop outright, but I don't know how common it is for tank crews to be armored up to that level; I'd expect them not to be very armored due to the confines of the tank, but I could be mistaken).
