If Harrison Ford didn't know what "The Expendables" were all about before, he does now.

Arnold SchwarzeneggerInstagrammed a photo of himself, director Patrick Hughes, and Ford on the set of "The Expendables 3" on August 30, proving that you can always teach a Governator new media tricks. (Even if you can't get him to put out his stinky stogie.) Ford is wearing a flight uniform, and Arnold is rocking some sort of weird camouflage situation and sunglasses.

This isn't the first time one of the Expendables has used social media to make a splash. Star and series mastermind Sylvester Stallone took to Twitter earlier this month to announce that Ford would be joining the cast, and to throw shade at onetime cast member Bruce Willis, whom Stallone referred to as "GREEDY AND LAZY." (Sly likes all caps.)

We can only imagine the behind-the-scenes pressure that Stallone and Schwarzenegger are putting on Ford to jump into the Twitter fray. Though the person who is also named Harrison Ford on Twitter is probably hoping the "Star Wars" star will stay too grumpy for social media. For now, anyway.

"Expendables 3" hits theaters August 15, 2014.
