As for police bulletproof vests, their main function can only be to prevent low-speed and medium speed bullets - handgun bullets - from harming the police's body at a certain distance. But wearing bulletproof vests is not like entering a safe, where no matter how the gun is fired, it can be unscathed, because bulletproof vests have a certain degree of bulletproof performance under certain limited conditions. Next, we will introduce the protective performance of police bulletproof vests.
Bullet proof vests are classified into soft, hard, and a combination of soft and hard materials. Generally, their bulletproof performance gradually increases, but their weight also gradually increases. Police officers in various countries often prefer to wear lightweight soft bulletproof vests instead of bulky composite bulletproof vests, despite their good protective performance, for the convenience and flexibility of their operations.
However, due to technical reasons, the soft bulletproof vests equipped in various countries cannot achieve 100% bulletproof performance. At present, bulletproof vests are mostly tested according to the US NIJ0101.04 standard for V50, which means that when the probability of penetration of the bulletproof vest is 50%, the shooting distance of this standard is generally 5-15 meters. According to relevant information, according to this standard, police bulletproof vests with steel plate lining in China can generally protect various caliber handgun bullets at a distance of 5 meters and a speed of 300-450 meters per second, while soft bulletproof vests cannot provide effective protection against steel core bullets. But this does not mean that the standard for bulletproof vests in our country is low, because even the Belgian FNP series bulletproof vests, which are famous for their bulletproof performance, can only protect various caliber handgun bullets up to 3 meters away.
The bulletproof vest in the United States, known for its high technology and standards, cannot guarantee 100% bulletproof performance. According to media reports, a certain bulletproof vest that claims to be able to withstand handgun fire from 7.5 centimeters away and is equipped with over 200000 police officers in the United States was hit by bullets twice within 10 days in 2003, resulting in one death and one injury to two police officers. Of course, the investigation conclusions are all objective reasons: when the bulletproof vest was punctured, it was not worn and used within the effective data of the bulletproof vest protection standard.
This article mainly introduces the protective performance of police bulletproof vests. Based on the above analysis, it can be seen that in anti drug incidents, bulletproof vests were pierced by Glock pistols due to various potential factors. The proximity when hit is the main factor, just like the bulletproof vest in the United States that can block handgun shots from 7.5 centimeters away, none of which can prevent bullets because the criminal's shooting distance is only 2.5 centimeters. In addition, the use of steel core bullets by drug traffickers greatly increases the probability of bulletproof vests being punctured.
