Scouts This special rule is automatically lost by an independent character joining a unit that does not have this special rule, and vice versa.
Scouts are used to reconnoitre ahead and are always used in the vanguard of the army. To represent this, any Scouts in the army may be deployed as the start of the battle, even in scenarios where they could not normally be deployed. For example, if you are using a mission variant with the Escalation special rule, then your Scouts would set up at the start of the battle instead of being places in reserve. In addition to this rule, after both sides have deployed (including Infiltrators), any Scouts may make a 'free move'. The move happens before rolling to see who goes first. All of the normal Movement rules apply.
This rule does not apply if the Scouts begin the game embarked on a Transport.
Turbo-Boosters This special rule is automatically lost by an independent character joining a unit that does not have this special rule, and vice versa.
Units mounted on bikes and jetbikes may utilise turbo-boosters to move at extreme speed. When using their turbo-boosers they may move up to 24" in the movement phase. Controlling their bike at such speeds takes all their concentration and skill, however, so they may not move through difficult terrain, shoot, launch assaults, or move in the Assault phase in the same turn. In the following enemy shooting phase, treat the bike's Armour Save as being an Invulnerable Save, to represent the difficulty of hitting such fast-moving targets. A unit using turbo-boosters must end its move at least 18" away from its starting position to claim this Invulnerable Save, as it relies on flat-out speed.
