After a couple of short teaser trailers that mostly just listed off cast members, the first proper trailer for The Expendables 3 has finally arrived online. I’m sure we all know the drill at this point, but I think this new trailer does a pretty good job of showcasing a wide variety of action sequences interspersed with some fun scenes just hanging out with the crew as well. They’ve got gun fights, fist fights, bar fights, tank fights and potentially even some dog fights… what more could you ask for? The Expendables 3 hits theatres on Aug. 15th; check out the new trailer after the jump and let us know what you think.
