CC with multiple units

We don't currently know whether they can or not because the interim answer that prevents them from doing so is entangled in other answers that are now outdated and the FAQ dealt with base-to-base contact requirements about as well as the original rules did (that is to say; not at all)

Edit:
Oh yeah, and as Hachiman alluded to below; you have to declare ALL details of your skill on declaration with the single exception of where the target is.

All details and choices related to the execution of a Short Skill, Short Movement Skill, Entire Order Skill or ARO must be specified when it is declared. (See FAQs & Errata.)

Q: Do you need to specify all details of a Skill when declaring it? For example where the target is for a BS Attack, or where the template is being placed for White Noise?

A: Yes, with the exception of the target’s position, which is chosen in the Resolution step, before measuring Ranges. If the order of declaration is important, the active player chooses who declares first.

 

"When declaring a CC Attack, the Player must select one Trooper or Peripheral activated by the Order. "

They have to select the model making the attack when they declare the CC attack.

The point is that, after faq 1.1, it looks like Peripheral (Synchronized) Special Skill is capable of generating multiple CC situations, and for each you need to declare which model is attacking which target.
I think @Mahtamori was referring to this rule, which in previous thread was temporarily ruled differently (active player attacking only on one of them, but being attacked in all) but the faqs brought back to this version, which, in my opinion, is quite op and weirdly different from how coordinated and fireteam work.

The example in the faq is referring specifically to Chimera:

How does the Peripheral (Synchronized) Special
Skill interact with multiple close combats in the
Active Turn? For example if a Chimera and a
Pupnik are in one close combat, and a second
Pupnik is in another combat?
You have to choose one Trooper per combat. Each
combat have to follow the Close Combat with
Multiple Troopers rules.

 

@Sirk no, what I'm referring to is that we don't know if you're allowed to declare CC Attack without first being in base contact with anyone.

Eheh, then the one I'm mentioning is just "another" case when a situation was temporarily ruled one way and faqued the other, since I remember the forum answer concluding the Chimera player would only fight in one CC (but being reacted in all of them).

By the way, is interpretation of the Peripheral (Synchronized) case above right?
Actually, it is quite straightforward and with little space for interpretations, but the multiple active CCs feel so strange that it leaves me thinkning.

 

They were always able to fight in multiple CC's AFAIK (or at least they were in N3), the FAQ just clarified it.

My answer to the question is correct regardless. You need to declare the model making the CC attack at the declaration of the CC attack.

That means if you (can) declare CC attack as your first skill, you declare the model making it then.

If you move or idle etc first you don't have to declare which model would be attacking until you actually declare the attack. Often with multiple Pupniks in one combat in the active turn this means you can sacrifice one to get normal rolls with another.

 

It does sort of raise the question of what happens if you accidentally declare CC Attack spuriously - that is to say you declare CC Attack with all your Pupniks on the same target and then move them all into CC, picking the most preferential Pupnik to do the actual attack with and not giving your opponent the benefit of knowing who is actually attacking that they would otherwise be entitled to.
