I still remember the toy gun I used as a child. Those with plastic bullets pull the spring directly to the top and shoot. The spring will bounce the bullet directly. Although this kind of bullet is small, it hurts when it hits.
Then I used a slingshot. These people hold stones, hit the wall and hit the glass, and they can obviously feel the power. Especially if you accidentally hit someone, it would be tragic. My cousin once took a slingshot to school, and then his classmates played with it. As a result, he hit another student, who had a big bag on his head, and then his parents found the school and asked others to pay for it. My cousin can't escape punishment.
You see, this ordinary commodity will hurt a lot when it hits people, not to mention bullets.
Actually, guns are really dangerous. Otherwise, it would not be banned in China. Occasionally, there are some gun killings in the United States. If you know there are casualties, you should know that guns are dangerous.
Moreover, bulletproof vests are not all right after all. People's submachine guns can still penetrate you at close range, and bulletproof vests are generally anti-stray bullets. There is also a helmet that seems to protect the brain, but at close range, a direct helmet can penetrate.
We usually watch gun battles in movies, and even if the protagonist is shot, we can kill those people, but in fact, if he is shot, he will probably be dragged away. Especially in the legs or abdomen, it is more likely that you can't move. Like some submachine guns, the ak47 you see, even if you hide behind a door or a wall, the gun will go straight through when people sweep it. You can imagine how miserable it is for such a powerful bullet to hit you.
In addition, like pistols, submachine guns and snipers, their bullets are still different. Generally speaking, the bigger the bullet, the more lethal it is.
Like a pistol, the effective range is only a few hundred meters. Although it is still lethal hundreds of meters away, it is already difficult to hit people. However, if someone uses a sniper rifle, tell you to run 1000 meters before shooting. It is estimated that as long as you hit it, you will die.
