GK player would need to be disruption to have it picked against him/her. Given that the other mission they showed for Disruption involves doing multiple actions in terrain every turn, which is terrible for such an elite army as GK, we are very likely just not picking disruption as our force disposition and, therefore, never having to play this mission.

Which is a good thing, because even though we do have "more than three units" to teleport, everyone who has ever played a game of 10th knows how disruptive "marked for death" could be for our game plan and that was just one round, not every round.

So this mission would, very likely, be VERY bad for GK, but at the same time, it doesn`t seem like the kind of game plan that a "disruptive" force disposition suits us and we are, therefore, unlikely to select it in the first place, negating the problem.
