Caliber Is Justice! Development of Artillery and Ships

It mainly introduces the development and combat experience of armored vehicles, artillery and ships in World War I, World War II and the early post-war period. In World War I, the army's artillery mainly used six-inch caliber as suppressive artillery, and the five-inch class as the main artillery. The three-inch gun has always been used as a tactical artillery piece. The navy's setting and use of artillery calibers is different from that of the army. The navy mostly uses long-caliber, full-charge heavy artillery, equipped with armor-piercing ammunition. This novel and its characters are purely fictitious.
