A soldier should never be honored for something that was expected
Outskirts
Get the grunt there when you go out,but dont move on,when you first go out,there should be some flouresent lights there.not when you go all the way out to the wholel battlefield,the place where the jackels come out,the first door you go into to you can jump[crouch jump]
then look up and crouch jump forward.then if your looking forward,turn all the way around and look left,you should see an opening.jump left to it,then crouch jump up again[that 1 is a little hard you mich grenade jump]
then go left onto the other buildings,the area where the drones come.
Im sorrry its a long way and its hard to explain in words.....go to youtube and search "Halo 2 REX Sword"
