The South Korean military conducted live-fire missile training minutes after North Korea fired a long-range ballistic missile early Wednesday. 
 
The Joint Chiefs of Staff(JCS) said that the South's Army, Navy and Air Force staged the 20-minute combined exercise close to the Northern Limit Line in the East Sea from 3:23 a.m. in response to the North's missile launch. 
 
The Army's missile unit, the Navy's Aegis ship and the Air Force's KF-16 fighter jet joined the drill, each firing a missile at a simulated target set in consideration of the distance to the site where the North launched the ballistic missile.
 
The JCS said that the combined drill mobilized a Hyunmoo 2 ballistic missile, a Haeseong 2 ship-to-ground missile and a SPICE-2000 air-to-ground missile, which all hit the target simultaneously.
