It depend on the card wording. As Vladimir said placing and moving are different effects. I'll check it in few hours and update post with card text.
If all Soldiers in your Location have "Ghost", and a Hostile card is about to be placed in your Location, you may pay XP equal to the Hostile card's value to discard the Hostile card.
Word place have been used here but ... scenario "Sneak Attack" have soldiers with pre-selected skills both Ghost and Evasion. So there is still a question if both skills works the same and there is mistake in scenario or do they work differently.
