Besides the Armored Kill trailer that popped up earlier, two new screens for the Battlefield 3 expansion have surfaced since -- see them below.
Whereas the trailer featured new maps Bandar Desert and Alborz Mountain, these shots are set on a currently unknown map that looks an awful lot like Caspian Border. You can expect to get a full look at this one and another new one in the next trailer, whenever that hits.
One of the shots also show fancy new tank camoflauge. 20 vehicle specific unlocks have been touted -- no doubt these are part of that 20.
Armored Kill launches September, and should be $15.
