General John Hammer was the leader of Leo Redlodge's army patrol in Afghanistan. When it was blown up by terrorists. He and Redlodge were the sole survivors. Hammer then defected to North Korea when his Son and Daughter in law were accidentally killed in a U.S. army strike which Redlodge led. He then raised his granddaughter to hate Redlodge.
Hammer was contacted by "the Doctor" and offered a chance at Redlodge. All he had to do was spread a rumor that terrorists were going to steal a Korean missile. He then caught Redlodge and forced him to wear an electrosuit (a suit that electrocutes anyone who wears it).
