The South Korean military may fail to strike back at North Korea's border artillery as swiftly as needed in the event of a conflict because its internal communications equipment is obsolete, a lawmaker warned Monday, according to Yonhap News.
While the South Koreans appear increasingly confident they can destroy the North Korean artillery with counter-battery fire and air power, I think that this won't protect Seoul--no matter how quickly target data is sent to South Korean artillery units.
Ultimately, South Korean ground units will need to carve out a no-launch zone north of the DMZ to protect Seoul.
