The first official trailer for The Expendables 3 features the entire ensemble cast, including Sylvester Stallone, Antonio Banderas, Arnold Schwarzenegger, Wesley Snipes and Mel Gibson.

The 56-second teaser, which doesn't include any action scenes, begins with the silhouetted backs of Stallone and his crew walking toward the back of an airplane hangar. Midway, Stallone cures the 16 heavyweights, dressed in black combat gear and wielding machine guns, to turn around.

Expendables 3 introduces Mel Gibson's character Conrad Stonebanks, who co-founded the team with Barney (Stallone). Barney thought Stonebanks was dead after he killed him for becoming a ruthless arms trader. It appears he has dodged death and is out to seek revenge by destroying the new crew. Meanwhile, Barney will be recruiting several new, younger and more tech-savvy members to the team as a result.
