The rule states I am not allowed to declare an attack against neutral units, but goes on tostate that if when I declare such an attack, it is cancelled. Civilian rule last point states that it is not cancelled, but rather the civilian is not effected. Does this mean, that the RAW is that I can not declare an attack that will effect the civilian at all, as per the main rule's first sentence. Or does it mean that I can declare, it.. It goes on to be cancelled, and is not cancelled finally as per the Civilian rule's last bullet-point?
No it says you can't declare attacks against Allied or Neutral Troopers. So it's not cancelled but the Civilian is just not effected by the template but everyone else is.
It specifically is cancelled? "Therefore, if when declaring an Attack with a Template Weapon, an Allied or Neutral Trooper would be affected by the Template, that shot is cancelled"
Lets go step by step. You can not declare an attack that would include a civilian. That you are not permitted to declare the attack if the template would include a civilian in the area of effect you just can't declare it so you must declare something else if the template can't be placed in a way that it won't contact the civilian. The next bit need to be there because of involuntary templates (I can only think of Explode off the top of my head) if you meet the criteria for explode and a civilian is effected then the entire Explode is cancelled so nobody is effected. The only thing I don't quite get the reasoning for is what template weapon doesn't have a PS or cause states?
Civilian: Game element with attributes? Belongs to the army list of any player? Can spend Orders? So by this definition a Civilian doesn't actually count as a Trooper. It is Neutral, but not a Neutral Trooper.
You can declare a Template Attack agaisnt Enemy Model A, while a Civilian is under the template too. The attack is not cancelled, but the Civilian is unaffected. You CANNOT declare a Template Attack agaist a Civilian, while an Enemy Camo Marker is under the template too. The Civilian is not a legal target.
