Imperial and US customary measurement systems the Troy units of weight—the troy ounce used to this day for weighting precious metals. Edward I (1272–1307) broke the link between a coin's value and its weight when he debased the English coinage by introducing a groat (four pence) which weighed of 89 grains rather than the expected 96 grains. The groat was further devalued in the 1350s when its weight was reduced to 72 grains. During Saxon times land was measured both in terms of its economic value and in terms of its size. The Domesday Book used the hide, an economic unit of measure. In other references
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
