Leave the portable turret alone. Since it was CMT's idea first (Bungie announced it in Halo 3 long after CMT said it would be in Halo CE) they can model it themselves. And let's also remember, this is Custom Map Team, not Halo 3 map team. You guys don't have to do everything the way it is in Halo 3. (as in, the models can be original, more than just the one for Spartan III's.)
