Ballistic protection refers to the ability of materials or equipment to withstand the impact of projectiles, such as bullets or shrapnel. This protection is commonly found in items like body armor, helmets, and armored vehicles. The effectiveness of ballistic protection is measured by its ability to stop or slow down these projectiles, often classified by specific standards. Materials used for ballistic protection include aramid fibers, polyethylene, and steel. These materials are designed to absorb and disperse the energy from impacts, reducing the risk of injury. Organizations like the National Institute of Justice set standards for testing and rating ballistic protection gear to ensure safety and reliability.
