The rules state that: "If a Trooper in Hidden Deployment wants to prevent another Trooper in LoF from returning to a Marker State, they must place the corresponding Model or Marker on the table at the moment the opponent declares their intention to return to Camouflaged, Impersonation etc. State"; does the model who was camouflaging declare idle? Can he change order? Can the hidden model declare aro or he can only stop the camouflaging?
What happens is that the active trooper declares their entire order skill "I'm reactivating camouflage", and the reactive player chooses between: - Declare ARO with the hidden deployment model - Say "This trooper can see you" and reveal it (as trooper or marker, depending on what the trooper is capable of) Either one will cause the skill to fail, the choice for the reactive player is whether they want to do something more, or keep the marker state (if they have one). In both cases, the active player declared an entire order skill, they don't get any other opportunity to declare a skill that order.
Not to mention that this means that re-Camo is a sort of a "Sensor" for detecting Hidden Deployments, because the reactive player has no choice and has to reveal his HD Trooper. No roll involved either, straight up forcing you to show up. I have no idea why the reactive player with a HD trooper can't just bluff and say "cool, please re-Camo, there aren't any ARO coming your way".
it says, IF they WANT. It is not acting as a "Sensor" and completely optional by the reactive player.
OK, I looked at solkan's post and both options seemed like the only options for a reactive player in that situation. Which would've been ridiculous, obviously. Glad it's all optional then, that's a relief.
