Wolf Scouts

Instead of being set up normally, one unit of Space Wolf Scouts (and their Wolf Guard leader if they have one) can be sent out ahead of the army to operate behind enemy lines. If you decide to use this option then the Scout unit must be kept in reserve, even in scenarios that don't normally allow reserves to be used. When the Scouts turn up, they must enter play from the table edge that the opposing side's reserves enter from or retreat towards, rather than from their own side's table edge. If the opponent doesn't have a table edge then roll randomly to see which edge they enter from.

This special rule is automatically lost by an independent character joining a unit that does not have this special rule, and vice versa.

In the right circumstances, stealthy troops have the ability to work their way into a forward position on the battlefield. To represent this, units with the Infiltrate ability may set up in accordance with the Infiltrate special rule in any mission that uses this special rule. If the mission does not allow troops to use the Infiltrate rule then the troops in question must set up normally with the rest of the army. The Infiltrate ability does not allow units that would normally be in reserve to deploy on the table. If a unit with this ability is equipped with a transport vehicle, it loses the Infiltrate ability.

Any infiltrators deployed on the table at the start of the game are deployed after all other units. If both sides have infiltrators, toss a coin to determine who goes first and alternate deploying these units. Infiltrators may be set up anywhere on the table that is more than 12" away from an enemy unit, if no deployed enemy unit can draw a line of sight to them. Alternatively, they may be set up anywhere on the table that is more than 18" from an enemy unit, even if they can be seen.

Some units of infantry are especially adept  at moving through difficult terrain. Accordingly, roll an extra D6 when rolling to move through difficult terrain. In most circumstances this will mean that they roll 3D6 and pick the dice with the highest score.
