South Korean President Park Geun-hye's top security advisor Kim Kwan-jin warned Wednesday that South Korea will "strongly" retaliate should North Korea undertake any provocations to protest the decision by Seoul and Washington to deploy an advanced US anti-missile system here. 
Kim Kwan-jin, chief of the National Security Office under the presidential office Cheong Wa Dae, made the remarks a few days after Pyongyang warned of "physical actions" against the allies' decision to station a Terminal High-Altitude Area Defense (THAAD) battery on South Korean soil, according to South Korea's (Yonhap) News Agency. 
"If provoked, South Korea will strongly retaliate," Kim said during a session of the National Assembly's House Steering Committee. "For this, (the South Korean military) is ready." The former defense minister also brushed aside Pyongyang's latest warning of physical actions, saying that the communist state has "routinely" made menacing remarks against its southern neighbor. 
Kim also pointed out that although the THAAD battery will be a company-level unit, it would bear a "significant meaning" in terms of countering the North's nuclear threats. 
Last week, Seoul and Washington announced that they had reached an agreement to deploy a THAAD battery here to better cope with Pyongyang's nuclear and missile threats. 
THAAD, a core part of America's multilayered missile defense program, is designed to intercept incoming ballistic missiles at altitudes of 40 to 150 kilometers during the terminal phase of flight after detecting the missiles with a land-based radar system. 
A THAAD battery consists of six truck-mounted launchers, 48 interceptors (eight per launcher), a fire control and communications unit, and an AN/TPY-2 radar.
