Body armor is graded, and the domestic level is different from that of foreign countries.

The hierarchy in China is too complicated to say for a while.

Let me take the American NIJ bulletproof standard as an example.

There are four grades, but they are divided into 1 grade, 2A grade, 2 A grade, 3A grade, 3 A grade and 4 grade. Among them, those with A are bulletproof vests with only soft bulletproof lining, and others are bulletproof inserts.

Judging from the guns that gangsters may use, a level-3 bulletproof vest with a plug-in plate is generally enough, and the level-3 bulletproof vest can prevent ordinary 7.62X54 rifles fired by M 14 rifles. Moreover, many gangsters basically only have pistols, so 3A that can resist pistols is basically safe. And if you add a patch panel, it will be heavier and not flexible enough.

The survival rate of wearing body armor is based on the premise that all bullets hit the body armor. The protection of bulletproof vests is limited. If you hit your head or other unprotected places and lose too much blood, you have to hang up.

Those who say that bulletproof vests are only for debris protection, their knowledge only stays in the last century.

American soldiers are stuffing bulletproof plates into bulletproof vests.
