2. Through Unity, Devastation

In each of your Shooting phases, you can pick an enemy unit that is visible to your Warlord. Until the end of the phase, each time you make a wound roll of 6+ against that unit for an attack made by friendly unit within 6" of your Warlord, the Armour Penetration characteristic of that attack is improved by 1 (e.g. AP0 becomes AP-1).
