A ballistic shield is a protective device designed to absorb and deflect bullets and other projectiles. Typically made from materials like Kevlar or reinforced fiberglass, these shields are used by law enforcement and military personnel during high-risk situations. They come in various sizes and shapes, often featuring a transparent window for visibility. Ballistic shields are essential tools in tactical operations, providing cover for officers while they engage with threats. They can be used in hostage situations, active shooter scenarios, and other dangerous environments. The effectiveness of a ballistic shield depends on its level of protection, which is rated according to standards set by organizations like the National Institute of Justice.
