Tests of the active protection complex of the South Korean K2 Black Panther tank. This system is based on a three-dimensional radar and a thermal imager, capable of detecting approaching projectiles and ATGMs at a distance of up to 150 meters. The cost of one active protection system is 670 million won ($ 600,000). Since 2006, 40 billion won ($ 36 million) have been spent on the development of the complex. The active protection complex was tested on the K-2 tank by repeated shelling from the RPG-7 and the Metis-M ATGM.
