Question from our game tonight. If a trooper in a link team (of 5 in this case) is half within an eclipse grenade zone, and an enemy model moves into base to base with it's first short order while remaining entirely in the smoke (and will then attack in CC with it's second short), what ARO's are allowed? Can the attacked model chose to fire ranged in ARO even if it didn't have LOF due to the grenade blocking it? We presumed none of the rest of the link team could do anything in ARO since they have no LOF to the attackers, but we we couldn't decide what the correct answer was for the trooper himself.
Inside a Zero Visibility Zone, troopers can only declare Skills that do not require LoF or that require them to be in base to base contact with their target. The attacked trooper can CC attack back, dodge or dodge change facing. The rest of the link team can also change-facing if the attacker was inside their Zone of Control and doesn't have stealth. The reactive model can't fire ranged because it did not have a line of sight on the model until it was in base to base contact. Also, if the members don't all do the same thing, some members will leave the Fireteam (see Fireteam Integrity on the wiki.) For example, if the attacked model CC attacks back and the rest change facing, the model making a CC ARO will leave the fireteam. Only in the Reactive Turn, if the trooper declares any type of ARO different from the Fireteam's ARO, the one declared by all the Fireteam members. When any Fireteam member declares an ARO different from the Fireteam's ARO, then the players must consider the Fireteam's ARO to be the one declared by more than half of the declaring ARO Fireteam members. For example, in a five member Fireteam where only three of them declare an ARO, if two members declare one kind of ARO, and the third one declares a different ARO, this member will automatically leave the Fireteam. When there is no majority of ARO, for example, if the three members each declare a different ARO, then the player can choose which one is considered to be the Fireteam's ARO, while the other two members will automatically leave the Fireteam.
if the link trooper holds due to SS2 and the second short skill is an attack the linked trooper can also fire back as if he had LOF due to SS2
I believe that IJW has noted that he does not consider Sixth Sense to remove the requirement for LOF - you'd need to be targeted by a BS Attack through a Zero Visibility Zone in order to respond with a BS Attack of your own, regardless of Sixth Sense. That is; Sixth Sense removes the MOD associated with ZVZ, but does not grant LOF. @meikyoushisui answer should be correct, though Stealth is irrelevant (all models involved ignore it); only the skills that are declarable while Engaged are available to the trooper that's being Engaged. The remaining Fireteam members can only choose no ARO or those declarable for ZoC triggers. All Fireteam members can Delay until the enemy has declared their second Short Skill.
Awkward, considering Sixth Sense explicitly says it allows you to do your thing without need for LoF.
Yeah, but if you take it as RAW it allows you to shoot through buildings if you get shot at by guided/spec fire weapons, or hacking attacks or Jammers. So as I understand most people play it as just meaning it allows you to ignore your facing for LOF. As always, Sixth Sense is a mess and needs rewriting.
Please let's not have this same argument again. @Trilker - I think your question has mostly been answered, with the note that there is some disagreement on whether or not a cc attack through smoke meets the requirements for sixth sense to allow you to use bs attack as an aro.
