North Korea has moved scores of tanks and armored vehicles to an Army corps near the border with China in Ryanggang Province. The 12th Corps, which was established in 2010, is tasked with responding to movements of Chinese troops in an emergency.

A source on Monday said about 80 tanks have been deployed in Ryanggang Province, where there had not been a single one before. The corps has been "turned into an attack force after it has been reinforced" with an armored infantry unit, a unit of multiple rocket launchers, and a special warfare and sharpshooter brigade.
