Well, I specifically mentioned Stalkers, not Enforcers. The initiative of the Stalkers is 12, so they go before the Skeletons. And what will they do on their first turn? Invisibility. And the Skeletons are out of luck. The Stalkers will attack them first, and they won't be able to retaliate. And considering the Skeletons' physical weakness and their penalty in melee combat, they don't have a chance (in my opinion).
