The United States (US) and South Korean Combined Forces Command (CFC) began the 2017 Ulchi-Freedom Guardian (UFG) Exercise on August 21, 2017. UFG is a computerized command post military Exercise. The exercises are the first large-scale U.S.-South Korea military drills since North Korea’s first-ever tests of an intercontinental-range ballistic missile (ICBM) in July 2017. This year’s exercise would, for the first time, include a nuclear war game.
