There are four levels of body armor ratings. Each level can protect the wearer depending on the handgun. According to NIJ, the first step to selecting the right body armor is choosing the appropriate level of protection of the body armor thus we should establish the level of protection that users need based on the realistic weapon threat they face. The body armor has not been known to fail to prevent the penetration of a bullet constituting a threat equal to or less than the protection rating of the armor. However, officers have died from the wounds received from weapons or ammunition exceeding the rated protection of the armor. The weight and bulk of the body armor are generally proportional to the level to the level of ballistic protection it provides therefore, comfort decreases as the protection level increases. Departments of the officers should strive to select body armor that their officers will wear, consistent with their ballistic protection requirements to ensure the safety of their people. The National Institute of Justice (NIJ) strongly recommends the selection of armor that protects against both the street threat and the officer’s handguns.
