I'm not looking at the code right now, but as I recall the ar2 energy ball is a vphysics object and only collides with other vphysics objects.
The grenades have vphysics objects as well as tracelines so they can hit animated entities' hitboxes as well. The strider has bone followers so the ar2 ball (and other vphysics objects) can hit those. I don't remember what the gunship's physics representation is - but maybe it has one that doesn't enclose a bunch of the model (or maybe it doesn't have one). So you could either modify the vphysics setup of the gunship (add bone followers?) or add tracelines to the VPhysicsUpdate of the ar2 ball to hit hitboxes like the grenade does.
