User blog comment:Deathmanstratos/Some Call of Duty: Advanced Warfare singleplayer background information revealed/@comment-98.155.204.8-20140506013231

I know that according to the Advanced Warfare Reveal Trailer that at the 0:18-19 mark the tail on the VTOLs have the acronym USAF, implying that the U.S. Military will somehow interact with the player either as a friendly faction or a faction that you change into during the course of the game.

Also, at a brief glimpse (if you time the pausing correctly) at the 0:20 mark as well as the 2:03 mark, with the picture of the VTOLs flying in formation, in the city on the left there is a structure resembling the Seattle Space Needle. Possibly implying that Seattle is a level.

at the 0:38 and the 1:11 mark, the sign on the overpass indicates the direction to "Keep Lagos Clean", Lagos, which is a city in Nigeria implies that the game will also take place there as well.

And at the 1:19 mark, as the Golden Gate Bridge is collapsing, it appears as if the San Francisco Police Department also appears as a friendly faction to the player.
