After both sides have deployed all their other forces (including Scouts), but before either side has taken a turn, units with the Vanguard special rule can immediately make a 12" move regardless of their Movement value (they can't march, and are affected by terrain as normal). This cannot be used to move the Vanguard troops to within 12" of the enemy.

If both players' armies contain Vanguard troops, players should roll off. The players then alternate moving their Vanguard units one at a time, starting with the player who won the roll-off.

Units that have made a Vanguard move cannot declare a charge in the first turn if their army goes first.
