Pulveriza

This (a bit from a GW FAQ recently released) is insane. That makes the Deff Rolla an absolute must. It can grind a Land Raider into dust!

Q. Can you use the Deffrolla when Ramming
vehicles or does it only work when Tank
Shocking non-vehicle units?

A. The death rolla does indeed inflict D6 S10 hits
against vehicles, as Ramming is just a type of
Tank Shock.
