Tyrant Guard

While this unit is within 3" of any friendly HIVE TYRANT models, add 1 to the Attacks characteristic of models in this unit.

While a friendly HIVE TYRANT model is within 3" of this unit, that HIVE TYRANT can use the Look Out, Sir rule even if this unit contains fewer than 3 models. HIVE TYRANTS within range of this ability gain the benefits of Look Out, Sir even though they are Character units with a Wounds characteristic greater than 9.

If your army is Battle-forged, then for each HIVE TYRANT model included in a Detachment, you can include one TYRANT GUARD unit in that Detachment without it taking up a Battlefield Role slot.
