# Turret

## Main turret bone

The `turret` bone represents the visible part of the hull corresponding to a tank's turret.\
It is linked to `body` bone.

If the real-life counterpart has rotation functionality, the `turret` bone operates using inverse kinematics.

## Checklist of possible elements linked to the `turret` bone

* **Primary bones**:
  * `rot_gun`: the main gun of the turret.
* **Secondary bones**:
  * `detail`: visual detail, if specified by the model's design;
  * `shield`: additional armor part, if specified by the model's design;
  * `enumerator`, if the vehicle model typically features an **Identification Number** on the turret);
  * `cover`.
* **Helper bones**:
  * Machine gun bones (if specified by the model's design);
  * `gunner2`: the position for the anti-aircraft gunner;
  * `fxfire2`: effector for spawning special effects like turret fire;
  * `turret_vol`: defines the visible turret shape and manages its collision with the game environment.
