Today we get the first official trailer and some release info for the latest expansion to Battlefield 3 titled Aftermath.

The expansion adds four new maps, three new vehicles, ten new assignments, ten new dog tags, and five new achievements/trophies. There will also be a new mode called Scavenger.
