Concealed Positions Each unit from this Formation that deploys using the Infiltrate rule and does not have the Stealth special rule is Concealed. A concealed unit has the Stealth special rule until it Moves, Runs, Turbo Boost, Charges, or Falls Back, at which point it immediately loses the Stealth special rule for the rest of the battle.
Precision Shots If a model with this special rule rolls a 6 To Hit with a shooting weapon, that shot is a 'Precision Shot'.
Wounds from Precision Shots are allocated against a model (or models) of your choice in the target unit, as long as it is in range and line of sight of the firer, rather than following the normal rules for Wound allocation. A character that has a Precision Shot Wound allocated to it can still make a Look Out, Sir roll.
Note that Snap Shots and shots from weapons that scatter, or do not roll To Hit, can never be Precision Shots.
