North Korean leader Kim Jong Un has overseen firing drills by artillery units in the western region involving "newly-equipped super-large" multiple rocket launchers, state media KCNA said on Tuesday.
The drills came a day after South Korea and Japan reported North Korea's launch of several short-range ballistic missiles into the sea, its first such missile test in about two months.
Kim guided the drills on Monday that were aimed at testing the "real war capabilities" of 600 millimeter multiple rocket launchers and improving the operators' combat morale and readiness posture, KCNA said.
The drills also included simulating an air explosion of a shell of the super-large multiple rocket launcher at a preset altitude above the target, it said.
The unit displayed "high mobility and accurate and strong striking power" in carrying out a sudden combat mission, eliciting the young leader's praise, it said.
