Chongchon River
The 187th ARCT’s DZs at Sukchon and Sunchon were up the arms of a "V" formed by the main highway and railway routes that converged at Pyongyang. Sukchon and Sunchon commanded the approaches to the Chongchon River, to the north. The main highway from Pyongyang to the Yalu River and the Manchurian border at Sinuiju formed the lefthand side of the "V." Sukchon was located on this highway in a wide valley surrounded by low hills. The righthand road passed through rougher terrain to Sunchon on the west bank of the Taedong River.
