Bring a Spectre [url=http://www.youtube.com/watch?v=8UKEsAUFh2s]in addition to the Banshee[/url] and clone Johnson several times. Get the Johnsons on the ledge. Plasma grenades from enemy Brutes won't move them (though it will affect the Spectre so you want to move that one back). Then attack Tartarus with the Banshee. Johnsons can see Tartarus even if he's cloaked, though their firing rate will be diminished iirc. Or try [url=http://www.youtube.com/watch?v=7qiCJqUR15Q.png]this out[/url]. With so many sword Elites keeping Tartarus busy, there will be an endless flow of friendly AI. With so many beam rifle Elites, Tartarus is -blam!- toast.
