Ghazghkull Thraka (Codex)

You can re-roll charge rolls for this unit.  When doing so, you can re-roll all or any of the dice.

When using the Leadership characteristic of this unit, you can use either its own Leadership characteristic, or you can choose for the characteristic to be equal to either the number of models in the unit, or the number of models in another friendly unit within 6" that has this ability.

Each time you roll an unmodified hit roll of 6 for an attack with a ranged weapon by a model in this unit, that hit roll succeeds regardless of modifiers.

In addition, immediately make an additional hit roll against the same target using the same weapon. These additional hit rolls cannot themselves generate extra hit rolls. When firing a weapon with randomly determined characteristics (ie. Bubblechukka), any additional hit rolls use the same characteristics as the hit roll that generated the additional hit roll.  This ability does not affect weapons that automatically hit their target.
