The NIJ standard requires that most bulletproof vests provided to US law enforcement agencies have a 5-year warranty period. This is the estimated time to maintain the level of bulletproof clothing. The frequency of wearing a bulletproof vest can affect its true level and protective effect. If you wear it to work every day, it will be more "used" than if you occasionally use it, thereby weakening it. In a few years, you should check the bulletproof plate of your vest. Check for signs of wear, such as cracks, wrinkles, burns, and even odors. If you follow the maintenance guidelines for bulletproof clothing, the vest should be able to wear longer.

Many countries, such as Germany and the United Kingdom, have their own standards for ballistic suits, but the NIJ standard 0101.06 has gained more or less widespread recognition. The bulletproof suit used to resist gunfire must meet the minimum performance standards and be tested according to NIJ standard 0101.06. This is a technical document that lists the minimum performance standards that equipment must meet to meet the needs of criminal justice institutions around the world. The maximum ballistic protection level of soft ballistic protective clothing is IIIA level. Additional ballistic plates are needed to provide better protection for rifle ammunition.
Female police officers should be able to wear bulletproof clothing that suits their bodies. Women's breasts require additional trauma protection, and their vests should have a true bra style cup, similar to the cup on a jumpsuit.
Most police officers wearing bulletproof vests will suffer less attractive abrasions due to blunt force injuries. However, this is unlikely to make you lose consciousness. Many armored officers can counterattack attackers, and in many cases, they can eliminate the threat. When you are 9mm or. 44 Mag bullet, you will experience intense stabbing, stabbing, and intense pain for a few seconds. Due to the deformation of kinetic energy and bullets within a fraction of a second, heat may leave small burn marks on the skin at the impact site. If you have a heart attack, you should seek medical attention immediately. If you have internal bleeding caused by organ rupture, an evaluation should be conducted.
