Marked For Death

(Rule)
Description: At the start of the battle, once both armies have set up all their models, including any units with the Infiltrator special rules, a single enemy unit may be chosen by a player that controls any models with this special rule - this unit is considered 'marked for death'. When any models with this special rule controlled by that player are used to make an attack of any kind against the eney unit their controlling player has 'marked for death', all failed To Wound rolls of '1' may be re-rolled.
