The first is a tiny new facility in the region just south of the disputed maritime border with North Korea — or the Democratic People’s Republic of Korea (DPRK) — established in 1953 by the United Nations Command as the Northern Limit Line (NLL). In late June, ROK announced the construction of an installation for up to 100 troops, featuring a small dock, barracks, and training grounds on the island of Baengnyeong. Baengnyeong is one of five islands west of the Korean peninsula in the area that saw the sinking of the ROK Navy (ROKN) warship ROKS Cheonan (PCC-772) by North Korea in 2010, killing 46 South Koreans. While the islands are not themselves claimed as part of North Korea’s own Inter-Korean Maritime Demarcation Line, they are often targeted as the outposts upholding the NLL; the DPRK in 2010 shelled another of the islands, Yeonpyang, killing four.
