For tactics I suggest you speak to some of the kilo leaders for xbone side.... Things may have changed since I left but when we played ghosts we would hold spawn and spread out to cover the 40% of the map on our side... Benefit of this is to stop enemy spawning behind you and keep them coming at you head on
How this would work for AW I don't know as I am yet to play with a team since returning, for reasons previously stated but the logic is still sound
