Target Sighted

(Rule)
Description: Each time a Tank Ace unit from your army (see below) Advances, do not make an Advance roll for it. Instead, until the end of the phase, add 6" to the Move characteristic of models in that unit. Each time a Tank Ace unit from your army shoots in your Shooting phase, if that unit did not Advance this turn, you can re‑roll the Damage roll. Adeptus Astartes Vehicle units from your army (excluding Fortifications, Drop Pods, Walkers and units that can Fly) have the Tank Ace keyword. In the Muster Armies step, you can select up to three Tank Ace units from your army to gain the Character keyword.  Designer’s Note: This means that the selected units can be given  enhancements, and one of them can be selected as your Warlord.
