There is, the "DirectRockingCoefficient=" tag. However, that is for Direct Rocking, which isn't good for an artillery piece that lobs shells some 20 cells ;i.e., shell misses, yet even if the target vehicle is no where near the shell it flips over no matter what (like on the other side of the map). DirectRocker= was orginally for the brute. But if there is a DirectRockingCoefficient= tag, wouldn't there be a plain ol' RockingCoefficient= tag? Just a hunch, but if anyone confirms that before me, post here.
I used "Rocker=" with 500 damage modifying the rocking amount guys, but the vehicle blows up before it gets a chance to tip over

. Even when the shell isn't htting it directly it STILL takes about 38 cannons to flip over one IFV. What is the probelm?
BTW, does anyone know where I can find a tutorial about making/recording new voice packs for units? That would be helpful.
