Body armor is protective clothing designed to absorb and deflect physical attacks, primarily from firearms and sharp objects. It is commonly used by military personnel, law enforcement officers, and security professionals to enhance their safety in dangerous situations. Body armor can come in various forms, including vests, plates, and helmets, and is made from materials like Kevlar and ceramic. The effectiveness of body armor is often rated based on its ability to stop different types of ammunition, with ratings established by organizations such as the National Institute of Justice. While body armor significantly increases protection, it is not completely bulletproof and should be used in conjunction with other safety measures.
