It could be tied to spawning default gunner on static M2 or M60:
```
SCR_BaseCompartmentManagerComponent compartmentManager = SCR_BaseCompartmentManagerComponent.Cast(m_Turret.FindComponent(SCR_BaseCompartmentManagerComponent));
if (!compartmentManager)
continue;
compartmentManager.SpawnDefaultOccupants({ECompartmentType.TURRET});
```
