Light-weight Combat Vehicle System Light-weight Combat Vehicle System The is a wheeled self-propelled artillery of the Japan Ground Self-Defense Force. Research on future multi-functional wheeled combat vehicle (Light-weight Combat Vehicle, LCV) is ongoing. LCV has remote turret with Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) firing capabilities, and dual recoil gun system providing adequate internal layout for combat crews. The LCV also has hybrid power system with in-wheel motors. The LCV provides both resistance against blast effect of IEDs (improvised explosive devices) by raising the chassis and improving driving stability. To satisfy such contrary requirements that light-weight vehicle carries large caliber gun, LCV has introduced breakthrough
