Our community isn't fluent in English, so we have a problem interpreting this FAQ: There are two positions: 1) Since there is a definite article before "ARO", you have to choose which action you are delaying when you declare a delay, i.e. "This trooper delays a BS Attack" or "This trooper delays a Dodge"; 2) You can choose whether you are Dodging or Shooting if/when the marker de-camoes, the "obligatory" part only refers to the fact that if you are delaying, then you must indicate that fact to the opponent at the moment you get this opportunity; i.e. "This trooper delays an action", and then after decamouing of the target "Now he does BS Attack". Which one is right?
You never HAVE TO do an ARO. You CAN do an ARO IF YOU WANT (and other requirements: LoF, ZoC...). You CAN delay your aro IF YOU WANT (and other requirements: SixthSense in ZoC, vs a Camo...). ... And that FAQ means: "IF you WANT DELAY your aro (in same situation other troops could do it) you must say it. I.e. - Camo "A" moves in LoF with Camo "B", -Camo B delay its ARO (optional). 01 -Camo A reveals itself, Camo B can do "all" possibles AROs. 02 -Camo A moves again, Camo B loses its ARO. <br>Una ranita iba caminando... Ps. Sorry my fail.
FAQ says: Q: Is it obligatory to declare that the ARO is delayed when waiting for the second Skill when a troop in Camouflage or Impersonation State is activated? A: Yes, it is obligatory. So accoring to the information in the original question one needs to specify which ARO he/she is delaying, if we take into consideration the definite article, is it important or not?
No. The definite article in this case is referring to the concept of the ARO as a whole, not to a specific Skill being declared. The FAQ is directly related to this: Bear in mind that when reacting to a CH: Camouflage or CH: TO Camouflage Marker, you may delay your ARO declaration until after the Marker declares its second Short Skill. And just means that you have to actively say if a trooper is delaying, rather than waiting for the marker to reveal itself and then surprising your opponent with an unexpected ARO.
And just to clarify (not that I can imagine a common situation in which you would do this): When you delay your ARO, you are delaying your DECLARATION of an ARO, so you can still choose not to declare an ARO even if the marker reveals itself with its second short skill. Is that correct?
