The design of steel body armor and ballistics mesh well when speaking about self protection. The history books have shown that bullets and firearms are parallel and the means of preventing death when one is punctured with bullets. Around the Middle-ages, and Italian blacksmith that was know for his skills creating body armor, was commissioned by the Duke to create the first bullet or projectile proof clothing. However as time went on it became clear that body armor was reducing the effectiveness of troops. It work soldiers out because it was too heavy and slowed soldiers nearly to a stand still. As weapons became more effective, more types of bulletproof clothing were tested but none worked and the evolution of bulletproof clothing slowed way down.
