coll is bullet impact. If you manage to remove the model (not null it's shader, but actually remove the model) it will usually take the coll with it. What you want to get rid of is their phmo... but it's possible that the rocks don't have their own phmo but just use the bsp for collision.

Collision is kind of a goofy word when it comes to Halo 2. You see coll, is short for collision, but it's kind of deceptive, since the coll only refers to an object's collision with projectiles. For example, in the Sentinel Base mod, there are the kind of arm-like things out at the edge of the map that look like you could walk on them. You can shoot them and there will be an impact. Fire a rocket and it will impact and detonate. Grenades will bounce off it. But if you get out there and try to walk on it, you'll fall right through. So would any vehicle if there were vehicles in the map, and if there were rocks or other blocs they'd fall through, too. This is because it lacks a phmo. Phmo is what keeps non-projectile objects, such as bipeds, from passing through an object. Technically, it's collision, but it's not coll.
As you may have noticed, Dazz, when you remove a model, you usually take it's coll with it: you can shoot through the space where your hog's wheels used to be; but their phmo is still there: if a fast-moving hog were to clip you with it's wheels (or the place where the wheels used to be) it would splatter you.
That was long-winded, but the point is that when the rocks were removed, their phmo remained, and I don't know if it's built into the bsp or if it goes with the scen. That's what you need to try to find out if you wanna' get rid of the rocks.
[edit] It's also worth noting that coll is one-sided in the same way as the models themselves: if you're inside the geometry (there was a spot like this in the first version of Sentinel Base) you can't see the walls: they're invisible to you. Your bullets will also pass through them. But if you're on the outside, trying to fire in, your bullets will collide with the model (these are often referred to as cheating spots when they're accidently left in maps). I don't know if phmo is one-sided since I've never gotten inside it to find out.

I will throw my 2 cents into this as well
The rocket launcher ammo has a coll tag but no phmo tag.
You can walk right through it. If you could change the collision model. I am psoitive it would make grenades and such bounce off differently. however, you could still walk through it.

I also looked at the pallete in zanzibar. If you change the collision tag for that and updated the phmo BB it will reflect the changes to the collision model. However rockets seem to miss it if don't shoot at where the original collision model would be.

Also bsp scenery, I am pretty sure has collision but it is not part of the bsp collision.

the rocks dont have a phomo or arnt part of the scenery

is it posssible that the rocks are just part of the ground?

here is the fast facts
bsp scenery is scenery who meta is contained in the sbsp tag
no, there collision is not part of the bsp collision so they have there own collision.
