N. Korea lifts "No. 1 combat ready posture": Yonhap

North Korea is believed to have taken its field artillery units off the highest level of combat readiness last week, Yonhap News Agency reported Tuesday, citing a senior South Korean government source.

"It seems that North Korea lifted the No. 1 combat-ready posture around April 30," the source was quoted as saying, adding that it also appears to have withdrawn two intermediate-range Musudan missiles from missile mobile launchers on its east coast.

On March 26, North Korea's state media carried a statement by the Korean People's Army's Supreme Command saying all field artillery units, including strategic rocket units and long-range artillery units, had been ordered "into the No. 1 combat ready posture."

It said the long-range artillery units targeted the U.S. mainland, Hawaii and Guam and U.S. military bases elsewhere in the Pacific as well as South Korea.
