Black Eagles can be shot down 3 times in an enemy Patriot Missile but harriers are weaker than the Black Eagles, capture a soviet construction yard so you can build iron curtain, if your superweapon is ready iron curtain your harriers, how's that... they can't shot down your harriers without any damage!!!! Remember you must build your airforce command near at the enemy's base, iron curtain runs out in seconds so you must be a fast player!
