Stealth A unit that contains at least one model with this special rule counts its cover saves as being 1 point better than normal. Note that this means that a model with the Stealth special rule always has a cover save of at least 6+, even if it is in the open. This rule is often presented as Stealth (X) where X indicates a specific type of terrain, such as Stealth (Woods) or Stealth (Ruins). If this is the case, the unit only gains the benefit whilst it is in terrain of the specified type. Cover save bonuses from the Shrouded and Stealth special rules are cumulative (to amaximum of a 2+ cover save).
Shrouded A unit that contains at least one model with this special rule counts its cover save as being 2 points better than normal. Note that this means a model with the Shrouded special rule always has a cover save of at least 5+, even if it's in the open.
Cover save bonuses from the Shrouded and Stealth special rules are cumulative (to a maximum of a 2+ cover save).
