First Modern Warfare 3 Teasers Released

The first series of teaser trailers for Call of Duty: Modern Warfare 3 have been released upon the world. They're all pretty much the same in that not much is shown, but they all play on a common theme: the number 3.

Each trailer gives a glimpse of a location where players will be taken to. So far it's, America, France, England and Germany. Take a look.
