As far as police body armor is concerned, its main function can only be to prevent low-speed and medium-speed bullets - pistol bullets from harming the body of the police at a certain distance. But wearing a bulletproof vest is not like going into a safe. No matter how you hit it, you can be unscathed, because bulletproof vests have certain ballistic properties under certain limited conditions. The following will introduce the protective performance of police body armor.
Bulletproof vests are divided into soft, hard and soft-hard combination types according to the material. In general, their ballistic resistance is gradually enhanced, but the weight is also gradually increased. In the execution of tasks, the police of various countries are often reluctant to wear heavy composite body armor with good protection performance for the convenience and flexibility of action, but are more willing to wear lightweight soft body armor.
However, due to technical reasons, the soft bulletproof vests equipped by various countries cannot be 100% bulletproof. At present, the bulletproof vest is basically tested according to the American NIJ0101.04 standard V50 in the bulletproof test, that is, when the penetration probability of the bulletproof vest is 50%, the shooting distance of this standard is generally 5 to 15 meters. Relevant data show that, with reference to this standard, police body armor with steel plate lining in my country can generally protect various caliber pistol bullets with a distance of 5 meters and a speed of 300-450 m/s, while soft body armor cannot protect against steel core bullets. Provide effective protection. But this does not mean that the standard of body armor in my country is low, because even the Belgian FNP series of bulletproof vests, which are famous for their anti-elastic properties, can only protect pistols of various calibers beyond 3 meters.
The American body armor, which is known for its high technology and high standards, cannot guarantee 100% bulletproof. According to media reports, it claims to be able to prevent pistol shooting at a distance of 7.5 cm. He was hit by bullets twice in the day, killing two policemen and wounding one. Of course, the investigation conclusions are all objective reasons: when the body armor is penetrated, it is not worn and used within the effective data of the protection standard of the body armor.
This article mainly introduces the protective performance of police bulletproof vests. Based on the above analysis, it can be seen that there are many potential factors for the bulletproof vest to be penetrated by the "Glock" pistol in the anti-drug incident. The short distance when being hit is the main factor. Just like the body armor in the United States that can block pistol shots from 7.5 cm away, one of them does not block bullets because the criminal's shooting distance is only 2.5 cm. In addition, the use of steel core bullets by drug dealers also greatly increases the probability of body armor being penetrated.
