Nearly all of the U.S.-ROK field training exercises postponed from August’s Ulchi Freedom Shield (UFS) drills on countering North Korean threats have now resumed, Seoul’s top military official said Tuesday, though not all were completed by their original September deadline.

Gen. Jin Yong-sung, chairman of the ROK Joint Chiefs of Staff (JCS), also assessed that North Korea’s newly unveiled Hwasong-20 intercontinental ballistic missile (ICBM) may have incorporated Russian technology, while stressing that ROK defenses remain capable of intercepting the new Hwasong-11Ma(E) hypersonic short-range ballistic missile (SRBM).
