Question that came up boils down to this:
If a model (A) is shooting target (B) while behind a smoke (ZVZ) template, but is not in the template, nor shooting through the template, can another model (C) ARO through the smoke at the -6 penalty?
Assume the ZVZ is NOT between A and B, but IS between A and C. A is targeting only B, not C.
A is not in the ZVZ or interacting with it in any way. Can C ARO against A?
Put simply, does an attack blocked from LoF by a ZVZ always reveal the shooter, whether or not the attack was in any way interacting with the ZVZ?
In an active turn, miniatures with a Special Skill or Equipment which ignores the blocking of LoF created by Zero Visibility Zones, can perform a Ballistic Skill attack or Forward Observer before his target. His adversary, if he survives the attack (Succeeding at an ARM roll or corresponding reaction) and all enemy figures with LoF to the attacker can perform their ARO despite the Zone, because the attacker has revealed for a moment his location. If the reply is a Ballistic Skill attack, or Forward Observer, they must apply not only Distance and Cover Modifiers but the –6 Modifier for the Visibility Zone. So in this case, for a BS combat in, or through, a Zero Visibility Zone there is no Face to Face Roll, just Normal Rolls.
We have one group that claims the shooter needs to be acting either in or through the ZVZ to reveal himself, opening up the possibility for AROs.
The other group believes that the act of shooting makes it possible for any unit to ARO through the ZVZ (albeit after first strike and at a -6 penalty), whether or not the shooter used a some Skill or Equipment to ignore the blocking of LoF by the ZVZ.
Is this statement a prerequisite for the remainder of the paragraph: "In an active turn, miniatures with a Special Skill or Equipment which ignores the blocking of LoF created by Zero Visibility Zones, can perform a Ballistic Skill attack or Forward Observer before his target."
