The two main types of Body Armor Plate are ceramic and steel. Ceramic plates are lightweight and can stop smaller pistol rounds and some rifle rounds. They work by shattering the projectile on impact, absorbing its kinetic energy. However, ceramic plates are more brittle and can crack or break on repeated impacts in the same area. https://fortunetelleroracle.com/business/understanding-the-protection-provided-by-body-armor-plates-954328
