I know this has come up and been explained, but I'm having trouble finding any direct reference. I need to go ahead and bookmark whatever answer so I can pull it up on game. The Requirements of Sixth Sense are as follows: REQUIREMENTS In order to use Sixth Sense L1, An enemy must be inside the user's Zone of Control. That enemy must declare an Attack against the user. So, I have a chasseur in camo. A model declares a short skill and walks into ZOC and I hold. The other model then declares another move or declares an attack at an entirely different model. Can the chasseur respond? I feel like I've seen a lot of reference to using the chasseur to declare off of the second skill, but the requirements make it look like the chasseur has to be targeted.
You have to let your opponent know that your marker/trooper is using Sixth Sense to delay their ARO towards the model activated by the order. If you just hold your ARO, you've forfeited it. The requirements of Sixth Sense are misrepresentative of some of the things you can do with the skill.
How do I defend this in a game though? Is there a specific link or reference? It’s pretty hard to argue with the direct rules in the PDF/book, but the second “requirement” really only sometimes applies. Me “I use sixth sense to delay.” Them “I move here.” Me “I attack with my flamethrower” Them “sixth sense says enemy must declare an attack.” Me “.......” What’s the direct reason/justification/argument for being allowed to declare something?
You point them towards the examples. http://infinitythewiki.com/en/Sixth_Sense#Example_of_Sixth_Sense_L1_vs_a_rear_attack "Had the Alguacil declared a further Movement instead of a BS Attack, the Maakrep Tracker would have been able to declare an ARO against an unseen active enemy inside her Zone of Control (Change Facing)." That's a clear example that the Sixth Sense trooper gets their delayed ARO, without having been Attacked as the active trooper declared Move-Move. In fact, the main part of that example also reinforces it: "An Alguacil, in his Active Turn, declares the first Short Skill of his Order: Moving towards a Maakrep Tracker with her back turned, keeping outside her LoF. The Alguacil is now inside the Tracker's Zone of Control so she uses her Sixth Sense L1 Special Skill to delay her ARO, waiting for the Alguacil to make his move. The Alguacil declares a BS Attack as the second Short Skill of his Order. Now that she is the target of an Attack, the Maakrep Tracker uses her Sixth Sense L1 to react as if she was facing towards the Alguacil. The Tracker chooses to declare a BS Attack so the Order is resolved with a Face to Face BS Roll between both soldiers." If delaying required being the target of an Attack, the Maakrep wouldn't be able to delay 'against' the Move - the active trooper would have to target them with the first Skill of the Order.
the example given for how to apply the rule in an actual game : Note in the example how the Tracker was able to delay using Sixth Sense in response of an Alguacil that was simply moving along minding his own business, not attacking the Tracker in any way. Also note that had the Alguacil decided to Move+Move, the Tracker would still be able to declare an ARO after having delayed it. Example of Sixth Sense L1 vs a rear attack An Alguacil, in his Active Turn, declares the first Short Skill of his Order: Moving towards a Maakrep Tracker with her back turned, keeping outside her LoF. The Alguacil is now inside the Tracker's Zone of Control so she uses her Sixth Sense L1 Special Skill to delay her ARO, waiting for the Alguacil to make his move. The Alguacil declares a BS Attack as the second Short Skill of his Order. Now that she is the target of an Attack, the Maakrep Tracker uses her Sixth Sense L1 to react as if she was facing towards the Alguacil. The Tracker chooses to declare a BS Attack so the Order is resolved with a Face to Face BS Roll between both soldiers. Had the Alguacil declared a further Movement instead of a BS Attack, the Maakrep Tracker would have been able to declare an ARO against an unseen active enemy inside her Zone of Control (Change Facing). edit: I was too slow :)
