What would happen if you wore a bulletproof vest on top of a bulletproof vest?
It would depend greatly upon the characteristics of the vests concerned - it’s not a stupid question by any means.

Some very early vests actually had two protective inserts - using one would provide something like NIJ Level I (which doesn’t exist anymore) protection and using two would provide NIJ Level II. One might assume that using three would provide very good Level IIIA protection, but I’ve never tested that.

If the panels were reasonably stiff, the trauma protection would be pretty good, as well. I did a lot of testing on this type of vest in the early 1980s - they were good vests.

The table provided in NIJ Standard 0101.06, National Institute of Justice:


Thus, if you have two NIJ Level II vests and want to protect against penetration and trauma from NIJ Level IIIA, it’s possible that using the two together would accomplish that - I’m not recommending it, nor am I saying that it will work that way - I’m saying it might work - to know, you’d have to do lab tests. Naturally, if you have two vests of the same size with removable panels, inserting both panels in the same carrier would be more comfortable.

Note that under no circumstances will a soft body armor panel protect against rifle fire, nor is it likely to protect against stabbing weapons, unless specifically certified to do so.

We used to make assault vests with the same sized front and back panels, and some operators would use both panels in the front when making an intervention - it made the operator feel better and did provide a lot better trauma protection, meaning that they could keep going. Usually, they pinched a back panel from another vest in these circumstances.

I’m not recommending that, either - just recounting an anecdote. Since no training will ever provide protection against every circumstance, this is probably not a good practice - the better option would be to buy overbuilt vests in the first place. Any competent manufacturer will design a vest for specific requirements for institutional users - remembering that a testing regimen can cost tens of thousands of dollars.

I built my first ghillie suit with utilities, burlap, and glue. I don’t recommend a glue ghillie suit. I did it right the second time with a fishing net.

My second ghillie suit was excellent. I was the best-dressed guy at Sniper School. Here’s what I remember from 20+ years ago. I used a set of woodland utilities, top and bottom. Some guys used one-piece flight suits.

Here’s what I needed:

GI seabag, nylon (Army guys call them duffel bags.)
camouflaged utility trousers
camouflaged utility blouse turned inside-out
fishing net - I found it in a craft store. It was a piece of old, thick recycled fish net made of grayish-green cord, not a filament.
burlap, tan and green
more burlap
patience
spray paint (optional)
Find someone who can sew heavy-duty fabrics, like an upholsterer or convertible repair business. I found a lady who ran a tent repair shop and made sure she understood what a ghillie suit was and how it would be used for a lot of low crawling.

She deconstructed the seabag and sewed the pieces to the front of my utilities. She worked with a heavy-duty sewing machine she used for fixing tents and still broke a few needles on the heavy seabag material. An inside-out blouse allowed the pockets to still be functional, but the buttons needed to be repositioned to the other side of the front. She doubled up the seabag on knees and elbows, too.

The fishnet went across the back of the blouse and down the back of each leg of the trousers. The net needs to be securely attached. Ghillie suits snag on everything and you don’t want it coming apart.

Cut burlap into strips of varying lengths to be tied to the netting. Loop strips through holes in the netting, leaving two ends hanging. Vary the strips’ lengths and tie-off points; they do not have to be even. Repeat a few hundred times. Save the leftover burlap. You will always be adding more.

You can spend hours fraying the burlap. Some guys tied their ghillie suits to the Humvees and dragged them down the roads. Ghillie suits, like fine wines, get better with age.

You can change your ghillie’s base colors with spray paint. Add natural vegetation. Continue to add as necessary.

What materials are the body armor purchased in large quantities made of?


Military fans with military knowledge know that there are two types of body armor, soft and hard. The difference between them is that the latter needs to insert a hard bulletproof version on the front and back of the body armor. But regardless of whether they are soft or hard, their foundations are made of Kevlar aramid fiber or high-density polyethylene (HDPE).


Kevlar aramid fiber is as shown in the picture. It was developed by DuPont Company of the United States. It was first used to replace steel to make helmets. The earliest actual combat use was in the "Gulf War" in 1991. At that time, in the US military, almost Everyone wears a Kevlar helmet.

Kevlar aramid fiber has the characteristics of high modulus, ultra-fine fiber, and high weaving density. It also has permanent heat-resistant and flame-retardant properties and permanent anti-static properties (this is very important. I am most afraid of static sparks, and some high-precision electronic equipment are also afraid), acid and alkali and organic solution corrosion, high strength, high wear resistance, pull resistance... and so on so that it can not only make bulletproof vests And the puncture-resistant interlayer of helmets and even military boots.

However, the bulletproof effect of Kevlar made into body armor is somewhat unsatisfactory. The main reason is that it should not be too dense when it is made into body armor. If it is molded as hard as a helmet, the feeling of restraint is very strong after wearing it, which makes people very uncomfortable. ! It has an impact on breathing and body movement, but weaving it to a level acceptable to the human body will greatly reduce the bulletproof effect.

It is impossible to make body armor with aramid fiber by pressing film. It is too hard to wear, so it can only be woven with ultra-long ultra-fine fibers.

Due to the reduction of the protection ability of aramid fibers against relatively powerful bullets, the world's advanced chemical countries currently use high-density polyethylene as the material for body armor. High-density polyethylene is pressurized during the production process to make its molecular arrangement more perfect. Tight, this will significantly improve its willfulness and appropriate hardness. Since the silk thread processed with it is thinner, a higher weave number can be used when weaving body armor, so the bulletproof of the body armor woven with it effect will be better.

However, the production process of high-density polyethylene is very complicated, and it cannot be manufactured in countries with some chemical capabilities. In addition, it is difficult to get the molecular density just right during the synthesis and pressurization process, so its process is not very stable. In the case of different molecular densities in several batches, if high-density polyethylene threads with different densities are used to make bulletproof vests, the bulletproof effect will also be different. Moreover, the ability of this material to withstand the natural environment is worse than that of Kevlar aramid fiber (probably because the molecules are more active), and it will be denatured after a long period of storage, and the bulletproof effect will gradually decrease, so bulletproof vests There is a shelf life (up to 5 years)

A very prominent problem with soft body armor is that although it has good impact resistance and tensile properties, its effect of greatly weakening kinetic energy is not too high, that is to say: it can prevent bullets from entering the human body, but it can The problem is that the kinetic energy (Joules) generated by the propellant propelled by the incoming bullet is also very large, which prevents the local high-pressure effect of the bullet, but cannot release the kinetic energy of the bullet. This is like a sledgehammer, although it cannot penetrate the human body, it will cause strong blunt damage, and the huge impact of kinetic energy will damage bones and internal organs... Therefore, it is necessary to use soft body armor Basically, a hard board is installed.

At present, there are three kinds of body armor and hardboard. The first one is the alumina ceramic in the picture.

Alumina material has high density and is easy to obtain. The production process is simple and the price is cheap. It is currently the most widely used bulletproof plate. Its process flow is to put high-concentration alumina powder slurry (the fineness of the powder should reach the micron level) under high pressure. Injected into the gypsum mold, because the gypsum has good water absorption performance, the alumina slurry will be dehydrated and formed quickly, and then the obtained alumina plate will be calcined at a high temperature after the mold is removed to obtain an alumina bulletproof insert. The process of grouting is relatively simple to produce, and tens of thousands of pieces can be mass-produced within a day, so its price is cheap and the bulletproof effect is also good. It has also become a large number of protective equipment purchased by the military and police.


Although alumina ceramics are cheap and high-quality, they are relatively heavy, and long-term battles and marches consume a lot of human energy. In order to solve this problem, silicon carbide ceramic bulletproof plates appear. Silicon carbide is what we commonly call "emery". Its density is relatively low, so its weight is also very light, which is almost equivalent to the high-density polyethylene mentioned above, but its price is too expensive, is 4 to 5 times that of the aluminum oxide plate, and the purchase price is too high. It is fully equipped for general troops, and can only be used by special forces with higher operational risks.


Silicon carbide ceramics have excellent normal temperature mechanical properties and excellent oxidation resistance, and also have good corrosion resistance. Its high-temperature mechanical properties are the best among known ceramics...Using it to make bulletproof inserts can also Greatly save energy, the bulletproof plates used by the royal guards of local tyrants may all be made of silicon carbide ceramics.


Better than silicon carbide ceramics is boron carbide ceramics. In the periodic table of chemical elements, the order is hydrogen helium lithium beryllium boron, carbon nitrogen oxygen fluorine neon, sodium magnesium aluminum silicon phosphorus... The density of boron is smaller than that of oxygen. So it will be lighter in weight, but the price of boron carbide is extremely expensive, more than 8 to 10 times that of silicon carbide. The price of a boron carbide bulletproof plate may buy 50 aluminum oxide plates, but its bulletproof performance and silicon carbide The difference is almost the same, this expensive thing can only be used by people at the big boss level.

But no matter what kind of board, after the soft body armor is inserted, it can greatly weaken the kinetic energy of bullets and the impact of shrapnel. The kinetic energy and high pressure will be absorbed and dispersed by the board so that soldiers can better prevent kinetic energy damage and damage. Piercing damage from sharp objects.


Generally speaking, the procurement of bulletproof equipment by the armed forces of major countries should be based on actual needs. Usually, more than two pieces are equipped for each soldier on the battlefield. The bulletproof vest needs to be replaced after being hit by a bullet because its protection ability has declined. If you wear it a lot, you may be really hurt if you continue to wear it. Therefore, it is still necessary to configure a large number of them under the condition of relatively sufficient military expenditure.

** thought it was shooting practice as usual until the Russian instructor gave me a bulletproof vest **


Russia's special tactical shooting training is not only different from the United States special tactical shooting training, but it is very different from the shooting training of virtually every other country, which gave a visiting American military show crew quite a shock. Intuition and common sense told the Americans that the Russians were crazy.



Such live-fire training, the special forces members of the training, soon have a crazy idea: "I'm in the middle of the field, and these instructors who are yelling at me with guns and firing live rounds at my head, ears, and feet, probably really want to kill me!"

This is exactly what the instructors were hoping for. Yes, it was a crazy training course, but as the American film crew later said, it was the kind of advanced training that special forces members, VIP protection team members, and all those special people who needed this kind of expertise.

Moving in the gap of shooting, in the interference of several bruiser pushing, Shouting abuse, to always pay attention to their own protection object, hold the gun, prevent accidental fire or being robbed, and use a variety of positions to shoot quickly and accurately, and hit the human target in front of you, don't forget, the human target is standing next to their teammates, but also be careful not to shoot them.

The mixing of real people with paper targets and firing at different angles, or "trust shots," is not uncommon in special forces training in different countries, but it is unusual to see such training in such intense close-quarters confrontations and appears to be unique to Russian special forces training.

In order to take part in such special training, the participants must first pass the level, that is, the trainee has to wear a bulletproof vest, and the instructor shoots him in the chest with live ammunition, each participant in the training, experiences what it is like to be hit by a bullet, which will undoubtedly increase your courage and confidence. The Russian instructors assured the American trainees that they were using "soft-headed" ammunition and would be safe. Only later did the Americans know that the "soft head" was not the non-lethal rubber bullet they understood, but the "soft head" as opposed to the "armor-piercing bullet". Since the Russians usually used the armor-piercing bullet for training, this time in order to take care of the Americans, they used ordinary armored warheads, so it seemed quite safe.

Advanced Tactical Plate Carrier For Versatile And Minimalistic Protection

The most widely used type of ballistic body armor worldwide, plate carriers are worn by both members of the armed forces and the general public. The plate carriers in 2022 have only improved on their design and protection, which is why their straightforward construction and overall protection are so useful.

This year, I've kept an eye on every new plate carrier release, and the Quadrelease Tactical Plate Carrier is the one that has so far caught my attention the most.
The Quadrelease 2.0 plate carrier should be regarded as "industry standard" in terms of design and material quality when it comes to having the ability to fast attach/fast detach.

As you might imagine, this "industry standard" improvement to the fast attach/fast detach capability will be very helpful to civilians, soldiers, law enforcement, and first responders.

Let me share with you the two key characteristics of this plate carrier that make it the ideal choice for someone looking for flexible and minimalist protection.

ADJUSTABILITY
One of the most underappreciated features of armor systems is the ability to fully alter and manipulate a plate carrier. This adaptability means that you can modify it to meet your demands and to properly fit you and your body type. Your plate carrier must fit perfectly, and being able to adjust it appropriately will enable you to do that. To achieve optimal fit and body coverage, the perfect plate carrier should allow you to alter elements like the cummerbund AND the shoulder straps. You won't receive the necessary coverage and protection if your plate carrier is unable to adapt to create a correct fit, which could have disastrous consequences.
The degree of adjustability contributes to comfort by ensuring that there are no wear or pinch points. Adjustability is undoubtedly one of the most crucial features, despite the fact that it may seem minor or unimportant.

SYSTEM MOLLE
MOLLE, which stands for modular lightweight load-carrying equipment, is an acronym. You can use the straps on gear with MOLLE webbing to attach additional pieces of equipment and gear, forming a highly solid bond that won't shift or fail you. A MOLLE system is a common component of plate carriers, and it's a handy way to connect extra magazine pouches, first aid kits, or other shooting equipment you might require. The most widely used method in the world and the best way to attach items to your plate carrier is the MOLLE system.

When mounted to your plate carrier, this enables quick and simple access, and the best plate carriers will always include this system to give you more flexibility with their platform.

These two characteristics, along with others, make the release Tactical Plate Carrier the ideal plate carrier for those looking for minimal weight and adaptable protection. I strongly suggest taking a look at the Quad release Tactical Plate Carrier if you're in the market for a new plate carrier or are just getting started with tactical gear.

We have the best, most durable plate carrier at Zennison. We comprehend that you're purchasing a bulletproof bag because you want to protect yourself or a loved one. We make sure that the dependability of our products is thoroughly examined.

Which branches of the military get along the best?


On December 20, 2019, the U.S. Space Force was officially established and became the eighth federal military force. These eight military forces include the Army, Navy, Air Force, Marine Corps, Coast Guard, Space Force, and the U.S. Public Health Service. The officer corps and the National Oceanic and Atmospheric Administration officer corps, the first 6 belong to the armed forces, and the last 2 belong to the non-armed forces. There are only officers and no soldiers.

Among the six armed forces, the land, sea, air, marine corps and space force (Space Force) are under the jurisdiction of the Department of Defense. Only the Coast Guard is under the leadership of the Department of Homeland Security. However, in extraordinary times, the federal government can belong to it Ministry of Defense leadership.

The two unarmed branches are the National Oceanic and Atmospheric Administration Commissioned Officer Corps (NOAA Corps), which is under the Department of Commerce, and the U.S. Public Health Service Commissioned Corps, which is under the Department of Health. and Human Services leaders.


The eight military departments are listed as follows according to their establishment time:

1. The army has the longest history. It was established on June 14, 1775, one year earlier than the independence of the United States. There are 478,000 active soldiers. The military song is "The Army Goes Rolling Along".

2. The navy was established on October 13, 1775, 4 months later than the army, with about 339,000 active servicemen. The military song is "Anchors Aweigh".

3. The Marine Corps was established on November 10, 1775, less than a month later than the Navy, with about 185,000 active soldiers. The military song is "Semper Fidelis".

4. The Coast Guard was established on August 4, 1790. There are about 41,000 active soldiers. The military song is "Always Ready" (Semper Paratus).


Rank table of officers by service (chart: U.S. Public Health Service Corps)

5. The public health service officer corps was established on January 4, 1889, with more than 6,500 active officers. The military song is "Public Health Service March".

6. The National Oceanic and Atmospheric Administration Corps was established on May 22, 1917, with 321 active officers. The military song is "Forward with NOAA".

7. The Air Force was established on September 18, 1947, with approximately 333,000 active servicemen. The military song is "The U.S. Air Force".

8. The Space Force was established on December 20, 2019. It is the latest branch of the military. It is still in the process of reorganization, with an establishment of about 16,000 military and civilian personnel. There is no official military song yet.

According to the above data, the total number of active-duty soldiers in the eight military branches of the United States is about 1.38 million.

Q&A: Why are bulletproof vests so short?

These are selected answers in our Quora Space.


Johnathan Smith: I'm not sure that a properly sized plate carrier is short when you factor in the necessary range of motion one must have for mobility in combat. I think the most common complaint toward one after hot and heavy is bulky. If you're talking about why the protected area is small compared to the entire torso, well, that's another matter. The idea is to strike a balance between encumberance and protection of those areas that can take away your ability to remain ambulatory immediately. A hit to the diaphragm is pretty damning to the heart and lungs. It's also a sort of hedged bet. Playing the averages, so to speak, of most anyone trained to hit a target being trained to focus on the center of the torso at approximately the solar plexus because the damage will be crucial if not immediately fatal.

Richard Kilibreaux: Because they’re made to generic proportions. Fact is, current soft body armor is inadequate for total protection. The user needs the neck, shoulders, and lower abdomen area extended, and shoulder caps would go a long way to stopping lateral hits by .22LR!

Romil Prasram: Bulletproof vests, also known as ballistic vests, are designed to protect the vital organs of the torso, including the heart and lungs, which are critical for survival. While some bulletproof vests may look short compared to other types of protective gear, they are actually designed to cover the entire torso from the collarbone to the waist, which is the area where vital organs are located.

The reason for the shorter appearance of bulletproof vests is that they are typically worn underneath clothing, so they need to be relatively lightweight and flexible in order to be comfortable for extended periods of time. As a result, bulletproof vests are often designed to be as streamlined and unobtrusive as possible, which can make them appear shorter than other types of protective gear.

It's worth noting that there are different types of bulletproof vests designed for different purposes. For example, a tactical vest worn by law enforcement or military personnel may be designed to provide more protection and coverage than a concealable vest worn by a civilian. Ultimately, the design of a bulletproof vest will depend on the specific needs of the wearer and the level of protection required.
