If an enemy unit deep strikes onto a servo skull is it a mishap or does the servo skull retreat? What about friendly units?
In the instance of an enemy unit deep striking and landing on top of the Servo Skull, the Servo Skull would be destroyed as according to it’s rules in the Wargear Section of the Grey Knights Codex. As the models have moved within 6″ of the Servo Skull causing it to self destruct. As for a friendly unit that land on top of it, you would just place the models around it as best you can so they’re as close to the landing point as possible.
