Stepping out of his thighs, Allison ran downward.

It was already dark inside, and Allison had just run to the staircase in the basement when he saw several figures below.

Almost without any hesitation, Allison's hand grabbed a flashbang at once, and then threw it down.

"Close your eyes!" Allison shouted.

"Boom!" The flashbang instantly lit up, and in the darkness, the bright light that suddenly flashed out made several people below scream suddenly, and then, Allison didn't take the stairs, almost directly turned his legs, and jumped down, at this time, he was agile like a monkey.

At this time, it is inconvenient to shoot, and I don't know if it is the BS people or my own hostages who are below at this time, so I can only use this non-lethal weapon.

If the person below is your own person, you should be able to understand this word, and if you close your eyes, you will not be injured.

When Allison jumped down, he heard a bang, and secretly screamed in his heart, and when his left eye looked at the night vision device, he saw a guy below, holding a grenade in his left hand, and his right hand had opened the bracelet.

There were still people who arrived before them, these few people, who were already on the first floor, so, when there was an explosion outside, they pulled their legs down, but unfortunately, they were fast, Allison was faster.

These people don't have too many weapons in their hands, they belong to the patriotic students who besieged the embassy at the beginning, for them, it is not good to have too many weapons, but there are still grenades.

Now they are going to rush to these hostages with grenades, and if the Americans want to save the hostages, then they will die together.

But it was still a step late, and when they watched the Americans come down, their instinctive reaction was to pull the grenade tab and throw it out!

At this time, this place is quite narrow, and there is no way to dodge at all, and Allison is also in a hurry after seeing that this guy has already pulled the ring of the grenade, and immediately flew up and kicked at this guy.

"Smack!" The grenade fell underneath his body, and with that, he was kicked down so hard that he collided with the opposite wall and lay down.

Under his body, he was a little panicked, and he immediately thought that this was his grenade!

That's right, it's a grenade!

This grenade has been pulled apart, the fuse is delayed, it is only a few seconds, and now, when he wants to get up, he feels a sudden sinking on his body.

"Ouch!" The second patriotic student has been kicked down by Allison.

Allison was almost a chain leg, first put down one, and then put down the second, the position was quite clever, just the two pressed together, and then, Allison's body, curled up in a corner.

"Boom!" A huge explosion sounded.

The two patriotic students stacked Arhats and suppressed the grenade, so that the moment the grenade exploded, the shrapnel was almost blocked by the two of them.

Even so, there were still some shrapnel flying, and Allison felt that his arm was like being bitten by a snake, and he began to hurt hotly, and when he covered it with his hand, it was all covered with blood.

Who would have thought that he would actually hang the lottery here.

Fortunately, there is a bulletproof vest to save my life, and I only hit this one.

In later generations, no matter where the American army fought, they all wore bulletproof vests, and the lives of American GIs were the most valuable, and at the same time, this also gave people a false sense that bulletproof vests were a kind of high-tech, and only later generations of soldiers had this treatment.

Not really.

If you talk about it earlier, the armor worn by ancient warriors can be said to be a kind of body armor, and it will definitely be bulletproof.

In modern terms, it should be considered to have begun to appear in the late 19th century, and a few years later, in 1901, after the assassination of President William McKenley, body armor attracted the attention of the United States Congress.

The first thing to be introduced was silk, which was used in body armor. Although this body armor protects against low-velocity pistol bullets, it cannot protect against rifle bullets. Moreover, silk deteriorated quickly in the trenches, and this defect, coupled with the limited bulletproof capacity and the high cost of silk, made silk body armor snubbed by the U.S. Ordnance Department in World War I and failed to become popular.

In World War II, Britain and the United States began to spare no effort to develop body armor.

In October 1942, the British army first successfully developed a bulletproof vest composed of three high-manganese steel plates. In 1943, there were as many as 23 types of body armor trial-produced and officially adopted in the United States. Body armor of this period used special steel as the main bulletproof material.

In June 1945, the U.S. military successfully developed a bulletproof vest combining aluminum alloy and high-strength nylon, and the model was M12 infantry body armor.

In the Korean War, the U.S. Army was equipped with T52 all-nylon body armor made of 12 layers of bulletproof nylon, while the Marine Corps was equipped with M1951 hard "Dolon" fiberglass bulletproof vests.

Nylon-based body armor can provide a certain level of protection for soldiers, but it is larger and weighs up to 6 kilograms.

In this way, until the early 70s, Kevlar, a synthetic fiber with ultra-high strength, ultra-high modulus and high temperature resistance, was successfully developed by DuPont in the United States and soon applied in the field of bulletproof.

The advent of this high-performance fiber has greatly improved the performance of soft textile body armor, and at the same time, it has also greatly improved the comfort of body armor. The U.S. military took the lead in using Kevlar to make body armor and developed two models, light and heavy.

Although this kind of body armor has not yet been popularized in large quantities, in the special forces, the latest model of body armor has entered the use stage.

However, only using Kevlar's fiber fabric as the main material and bulletproof nylon cloth as the envelope, such body armor is still defective.

Therefore, the body armor of the special forces also added a bulletproof plate made of titanium alloy to the front and rear, which was placed inside, which was enough to resist the shooting of the rifle.

(The kind of military fans who can't resist rifle bullets with body armor are great, and they can learn more about bulletproof inserts on the battlefield, saving the lives of many American GIs, most of them are rifle bullet shots.) ）

Now, the body armor and helmet have saved Allison's life, and now Allison, although he has been injured, is still at the forefront.

"Quick, open the basement door!" Allison shouted to the man behind him.

"Boom, boom, boom!" In the back, a soldier who was in charge of breaking the door picked up a large fire axe, and with a few clicks, the door was violently cracked.

The moment the door was opened, everyone was stunned at first, and then they were pleasantly surprised.
