Remove promotion from unit?

[Wardly]

Is there already a method built in to remove add/remove a promotion from a unit? If not what table is it that so i can run a manual sql delete statement on?

Found it.

102: bUnit:SetHasPromotion(BrigandPromo,true);
103: bUnit:SetHasPromotion(UnFriendlyPromo,false);
