So I may have missed this when I was reading the rules, but a question popped into my head. Let's say for sake of argument that the Tau have at least one unit with the Ranged keyword (I would probably cry if they didn't, but smart moneys on the Vior'la Marksman). If I throw a Gun Drone attachment on him (Area of Effect (2)), does that mean he gets to hit all enemies with 2 damage during the range step? Or do the abilities not interact that way?
It looks like the Gun Drones text says that the unit to which it is attached "Gains" the area of effect wording. So effectively it looks like the ranged unit would have both keywords. Thoughts?
