In modern times, war is far, far away from them, and it is also very strange, the battles they know are usually in ** games, and some people think that when they go to the battlefield and wear a bulletproof vest, they can sit back and relax.
This is actually a big misunderstanding, because the biggest function of body armor is to block shrapnel and shrapnel in battle.
General body armor, that is, to defend against the power of firearms.
As for the rifle, that's even less to say.
Not to mention, those heavy machine guns, heavy snipers used 127 mm bullets too.
If you're in the wild by 12A 7 mm caliber bullet hits, and you'll have to ask for a lot of good luck.
Even if he is wearing heavy armor, under such power, he will be cut off by the waist.
12.7 mm large-caliber ammunition is generally used as a heavy **, such as Barrett's heavy sniper, which is used in this type of ammunition.
Such a sniper can be used not only to attack enemy soldiers, but also to break through the defenses of armored vehicles.
Chechen troops were used in battles in Chechnya 127 mm machine guns inflicted too frequent strikes on armored vehicles of the Russian Army,
One shot penetrated the defenses of the armored vehicle and killed everyone. Therefore, in the middle of the battle, don't think that you can be invincible with a layer of bulletproof vests, and a thin layer of bulletproof vests just makes people feel a little at ease.
