According to former North Korean soldiers, the regime's special forces are capable of striking over 90 percent of targets in the South.Retired South Korean General Lee Won-seoung said on Tuesday at a forum organized by the Army that based on statements from North Korean troops who defected and drills simulating an infiltration of the South, the communist state could strike most major facilities in South Korea.The general also said that the South's military should beef up its high-tech surveillance such as unmanned aerial vehicles and infrared cameras to better deter a North Korean attack.
