Ballistic armor is protective gear designed to absorb and deflect the impact of projectiles, such as bullets. It is commonly used by military personnel, law enforcement officers, and security professionals to enhance their safety in dangerous situations. The armor is made from materials like Kevlar, ceramic, or polyethylene, which are engineered to withstand high-velocity impacts. There are different levels of ballistic armor, classified by the National Institute of Justice (NIJ) standards. These levels indicate the armor's ability to stop various types of ammunition. For example, Level III armor can protect against rifle rounds, while Level II is effective against handguns.
