Атака имперсонатора действует так же, как и атака из ТО. Аро выполняешь только по факту выживания/
An impersonator not yet discovered can make a Ballistic Skill attack before his opponent can react. Therefore, no Face to Face Roll is made: each figure makes a Normal Roll of BS, the impersonator going first. If his adversary survives the ARM Roll, he may then return fire. After firing, the impersonator’s miniature replaces any IMP Marker.
The only possible ARO against a Impersonator is Discover or Change Facing. However, it is not compulsory that the ARO be announced immediately after the adversary declares the Marker’s first Short Skill. It is possible to wait until the Marker declares its second Short Skill, and if it reveals its presence, then an ARO may be generated to react accordingly. This rule does not cancel the advantages of Impersonator.
