Rangers

Squad may deploy using Infiltrators special rule

Rangers add +1 to any cover saves it is allowed (e.g. a 5+ cover save becomes a 4+ cover save). If not cover, they are granted a 6+ cover save.

Rangers moving through difficult terrain can roll one additional dice when determing their movement distance.

Eldar units with this rule may run instead of shooting in the shooting phase. Roll a D6. The score is the distance in inches the unit may move in the shooting phase. This move is not affected by difficult terrain.
The Avatar; vehicles; jetbikes; any model with a saving throw better than 4+ (with the exception of Dire Avengers, Howling Banshees; Fire Dragon Exarchs and Phoenix Lords); units contain anti-grav/support weapons; and Dark Reapers may never run.

At least half the units (rounding up) in any Ulthwe Strike Force must be kept in reserve and enter play through a Wraithgate as described below, regardless of mission. These units must be noted down before deployment. Regardless of the mission being played, any unit that carries a Wraithgate automatically begins on table following the usual deployment rules.

Ulthwe Strike Force troops that are falling back must do so towards the nearest Wraithgate if one has been placed. If they are unable to they will fall back as specified in the mission. If a model from a unit that is falling back passes through the Wraightgate the entire unit is removed from play as if they had left the table. If the only model left on the table carrying a Wraithgate is destroyed, the Wraithgate is placed wih the central hole over the spot where the model died.
