Would I be allowed to use the Meteorite (special object with a red ring) and the new Tank Turret and a light object on my force.

Yes, that would be 1 light and 2 heavy objects.

Ok thank you I figuard it would be ok but I just wanted to make sure.

So does that mean the Tank Turret, although it has the special object symbol counts as the heavy object? So you could use say green lantern (yellow), tank turret (heavy), Gamma Bomb (other)? Does this mean you could use the turret if you are playing the gauntlet?

I'm not sure what you mean by "although" here. Special objects can be any "weight" such as with the Green Lantern (light), Dumpster (heavy), or Kinetic Accelerator (immobile).

Yes.
No. It is a special object.

Thank you Harpua, very clear!
