Task: Question Answering
Input (English): Passage: The Expendables—led by Barney Ross and formed by Lee Christmas, Gunner Jensen, and Toll Road—extract former member Doctor Death, a knives specialist and team medic, from a military prison during his transfer on a train. They recruit Doc to assist them in intercepting a shipment of bombs meant to be delivered to a warlord in Somalia. Arriving there, they reunite with Hale Caesar, who directs them to the drop point, where Ross is surprised to find out that the arms trader providing the bombs is Conrad Stonebanks, a former co-founder of the Expendables who went rogue and was presumed dead. In the ensuing firefight, The Expendables kill all but Stonebanks, who shoots Caesar. They are forced to retreat due to Stonebanks' advanced weaponry, and Caesar is severely injured.
Back at the United States, CIA operative Max Drummer, the Expendables' new missions manager, gives Ross a mission to capture Stonebanks to bring him to the International Criminal Court to be tried for war crimes. Blaming himself for Caesar's injuries, Ross disbands the Expendables and leaves for Las Vegas, where he enlists retired mercenary-turned-recruiter Bonaparte to help him find a new team of younger mercenaries. The recruits include former U.S. Marine John Smilee, nightclub bouncer Luna, computer expert Thorn, and weapons expert Mars. Skilled sharpshooter Galgo asks to be included in the team, but Ross turns him down. 
Question: Who does the former co-founder of the Expendables shoot?
Output (English): Caesar.
