Stealth

Stealth troops are troops that cannot be seen by people other than the person who deployed them, that person's allies, and players with stealth troop detection active. They are ranged from Navy Seals, to Spies. Now granted, they are not the best troops to attack with, because their attack is 5-7, and their Defense is even worse some times. But, having 10 of these troops spells death for a city.
