One AK model was also seen in the trailer, it definitely had a 7.62 magazine, but nothing else in the video is clear. The GameTrailers Analysis states that it is an AK-103 but this is unconfirmed. In the May 24th Trailer, many other AK variants were shown with odd custom paint camo's, most notably some looked like AK-74 Models while other's looked like the more modern AK-103 models.
Definite, seen with no attachment and possibly seen with suppressor. The May 24th trailer shows a brief scene of the Vector being used with it's experimental 26 round magazine and possible Eotech Holographic sight.
MP5
Possibly the MP5K variant, definite.
Benelli M4 Super 90
Highly probable.
IMI Desert Eagle
In one scene of the new trailer, presumably a secondary bad guy carries a Jericho 941 Handgun with a laser aiming module attached it. It's hard to say as to whether this is a Jericho or a Desert Eagle, however it appears to be too small to be a desert eagle. He quickly shoots two agents in a quick draw at point blank before possible shooting a third sitting in a car.
Confirmed as a Desert Eagle.
TMP or B&T MP-9
A TMP or a Brugger & Thornet MP-9 is seen very briefly during the Snowmobile chase, fired one handed and a slight angle.
