Troy weight Troy weight Troy weight is a system of units of mass customarily used for precious metals and gemstones. One troy ounce (abbreviated "t oz" or "oz t") is equal to exactly , (or about 1.0971 oz. avoirdupois, the "avoirdupois" ounce being the most common definition of an "ounce" in the US). There are only 12 troy ounces per troy pound, rather than the 16 ounces per pound found in the more common avoirdupois system. The avoirdupois pound has 7000 grains whereas the troy pound has only 5760 grains (i.e. 12 × 480 grains). Both systems use the same grain defined
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
