South Korea showcased its largest ballistic missile for the first time as it marked Armed Forces Day in an apparent warning against North Korea's nuclear and missile threats. The ground-to-ground missile, dubbed a monster for its size, had been shrouded in secrecy due to its strategic importance. It is known to be able to carry a warhead weighing about 8 tons and capable of destroying underground bunkers. The transporter erector launchers crawled across the air base, each of them carrying a massive canister, apparently housing the "high-power" and "high-precision" missile known to be able to target anywhere in North Korea.
