Light-weight Combat Vehicle System technology so called Dual Recoil Gun System. In the system, the primary recoil brake can reduce the firing reaction, followed by the secondary recoil brake which reduces the force even more. With this technology, the LCV can carry a large caliber gun on light-weight body. 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
