The K21 Infantry Fighting Vehicle, armed with a stabilized 40mm automatic cannon and anti-tank guided missiles (option), can engage the enemy’s main battle tanks as well as all light armored targets. The high mobility of the K21 is comparable with main battle tanks, and its air-bag floating system enables amphibious missions.

The inter-vehicular data communication system and battlefield management system connectable to C4I provide the combined joint operation capability in a network-based future battlefield environment.

The K21 Infantry Fighting Vehicle is one of the main powers of the armored and mechanized forces in Korea.
