Just hours after new details on the game came to light, Activision has launched the first of likely many teaser trailers for Call of Duty: Modern Warfare 3 via Facebook. Subtitled "America Under Siege," the all-too-brief clip drives home the fact that a focus of the modern combat occurring in this installment will be the USA's own front lawn.

Update: 2nd New Trailer - England Under Seige
