Unless Burlok is fleeing or engaged in combat, once per turn, during the Shooting phase, a friendly unit of Quarrellers, Thunderers or a Dwarf war machine that is within his Command range can either re-roll any rolls To Hit of a natural 1, or re-roll a single Artillery dice. In addition, Burlok and any unit he has joined do not suffer the usual -1 To Hit modifier when shooting at Long Range.
