Months later, after Vanko attacked the Stark Expo, the Ten Rings set up a trap for James Rhodes, a friend of Stark and pilot of the War Machine armor, in order to take his suit, but they failed. However, the soldiers of the Ten Rings informed their leader, the Mandarin, that they managed to scan the armor during the battle and get enough information that would help them get their revenge on Tony Stark.
