(Answered) Special armour question

[Lorcan Nagle]

Do the effects of special armour abilities remain after a unit has lost all armour points? For example, a unit with RFA takes a hit that only damages structure, do you still reduce the total damage by 1 (or half if the attack is ENE)

For RFA, yes. RFA is not removed from the unit when it's armor, and the RFA ability doesn't specify the unit must have armor remaining (or that armor must be damaged).  Reactive and Ballistic-Reinforced are the same.
