During the cold weapon period, all the soldiers who went to battle to kill the enemy wore armor, which could effectively reduce casualties. Since guns were invented, armor has basically been useless and vulnerable under the power of rifles. With the development of science and technology, after the birth of bulletproof vests and bulletproof helmets, soldiers finally got effective protection.
Bulletproof vests are also called bulletproof vests. The place it can provide protection is extremely limited, only the area in front of you. So since body armor can effectively protect against bullets, why not protect both arms and legs? If this is done, can the soldiers be effectively protected? However, the reality is very cruel. If the body armor protects the limbs of the soldiers, it is likely to increase the casualty rate of the soldiers.
Modern body armor is still in its infancy. Whether it's a flapper or Kevlar, it can't guarantee safety absolutely. They can resist stray bullets or fragments more often. If a soldier wears a body armor and is shot by the enemy head-on, no matter how tightly he protects, he cannot guarantee his safety. Of course, humans have the conditions to create a body armor that can withstand any bullet damage. If you use a steel plate a few centimeters thick for protection, it is impossible for the bullet to penetrate the body armor, but the soldier will definitely be unable to move after wearing this body armor. NS.
Even if the body armor that only partially defends bullets is worn on the body, it will affect the soldiers' actions. If the soldiers' limbs are protected with these body armor, the soldiers' hands and feet may not be able to move normally. Flapper body armor will bring a great burden to soldiers, and Kevlar's body armor will also restrict the soldiers' actions to a certain extent. Originally, body armor was used to prevent bullet fragments. The thing that caused the most casualties on the battlefield was shells. Body armor and helmets actually serve this purpose.
Of course, there is another important reason. The head and the human torso are the most important parts of the body. Once these two places are attacked, it will be fatal in all likelihood. The limbs are different. Even if he is shot, the probability of surviving is still very high. Instead of wearing a body armor that prevents your movements to protect your limbs, it is better to increase your flexibility and increase your chances of survival through flexible tactical movements. The fighters' tactical movements are all done by the limbs. If the limbs are wrapped, it is difficult to complete the tactical movements. Even the soft body armor will slow down the movements of the fighters. Wearing more protective gear, because too hot will also cause a huge consumption of physical strength, especially when worn on the legs, the effect is greater, more force and more sweat are required.
