I was i awe at how thin and light it was. He inserted a reinforced plate in that goes over the heart. I looked at him in wonder. "And this stops bullets?" "Yep. But it's still going to hurt. A lot. Like getting hit with a 16 lbs sledgehammer in the chest." "That sounds horrible!" I cried. He looked me straight in the eye and said very simply "It's better than being dead." That conversation has stuck with me over the next 35 years.

In the early 2000s Second Chance (a body armor company) started marketing a vest made out of a material called Zylon which was manufactured by a Japanese company called Toyobo. The weight of the vest was nearly half of what the standard issue level 2 soft body armor vest was and was much more flexible. I, along with several of my fellow officers, paid extra to upgrade to these vests from our standard department issue vests. About 1-2 years later we were getting reports that officers were suffering penetrating gunshot wounds, including an Oceanside PD officer being killed, while wearing this new vest. Apparently the material would start to degrade after about a year of sweat and body heat. It resulted in numerous lawsuits for injuries and replacement of the vests, and the company Second Chance filing for Chapter 11 bankruptcy. When I retired the body armor being issued was just as stiff as the stuff I was first issued in 1996...but at least it worked.

[@bsadewitz]

This was a big scandal at the time, right? I think I remember this. Had forgotten all about it.

[@Cgopat]

@@bsadewitz Yes. I think it ended up with a couple of officers being killed while wearing the vests. The feds had also bought a bunch of them. I was fortunate because my department reissued us their stock vest made of kevlar, reimbursed us the extra we paid for the zylon vest, then sued Second Chance for the money we paid out. Second Chance was bought out by another company, probably as a result of the millions lost on this vest.

[@TheRealAaronSmith]

​@@Cgopatglad you were in a department that actually cared for your officers. Thanks for helping keep law and order in the land. It's a role not many of us have the capacity for.

[@ridermak4111]

Yes, that whole situation sucked. But I think it would be fair to mention that the founder of Second Chance Body Armor, Richard Davis, was granted a handful of patents in 1969 (‘70?-‘71?) and was the first to develop a successful concealable Kevlar vest that saved the lives of many cops for decades to come. The only way he could create sales (no concealable garment yet had been effective enough to trust the concept) he built that trust by shooting himself in the chest in front of an audience of cops. The first time with a .38 special and immediately turned and engaged targets to confirm that the impact didn’t take him out of the fight. He continued this demonstration about 150 times, and for most of them he used a .44 magnum (but added a thick phone book under the vest to dissipate the .44 shock, the bullet never penetrated the vest). Last time I checked, which was years ago, he can be found during those early days, right here on KZbin. The first time was on what appears to be 8mm film.

[@seasonallyferal1439]

I was a ghetto security in Toronto. The vest company would replace our vests if we got shot... and survived. We used to keep 3-4 thick magazines in our plate carriers because an ice pick or syringe will go through Kevlar, but paper stops it.

Good lord. Magazines. I mean, they would work, I can't fault you there.

Plus, living in Ontario, you have no restrictions on owning or wearing body armour. Get yourself some quality equipment, bro! Especially if you're still living in the GTA. Even as a civvie, I wear a concealed IIIa when I'm going out for awhile, and I have an oversized UHMWPE lvl III+ SP plate in my pack at all times. Light enough not to bother me, and big enough that if shit goes down, I can put my son(until he gets a bit bigger) between me and the plate which covers almost all his vitals while I GTFO. His diaper bag has a IIIa panel in it as well. It's inevitable to become a statistic. But you don't have to be THAT statistic.

​@@ellwoodwolfyou're asking what the core of the bullet is made of? Typically lead, with a copper "jacket" or coating to help keep the gun clean and engage with the barrel's rifling for more consistent accuracy. Now, there are more specialized ammunition types that have other materials, but that's going to be your "basic" bullets. Armo(u)r piercing rounds will typically have a small diameter penetrator made of steel, or tungsten, or a similarly dense material that is pushed into and through armor by the rest of the bullet and its own inertia.

Except they got the cause of the US entry slightly wrong. It was the Zimmerman telegram that pushed the US into joining WW1. Germany was trying to get Mexico top attack the US to ensure it stayed out of WW1. Except this was sent from the Foreign Minister, Arthur Zimmerman, by telegram and it had been intercepted by the UK as the telegraph cables passed through UK territory. Being canny, the British held off passing this to the US, only doing so after Germany restarted unrestricted submarine warfare and sinking American shipping. The sinking of US ships might have tipped things eventually, but the UK 'suddenly breaking' a coded telegram, offering German support for a Mexican invasion of the US to retake Texas, Arizona and New Mexico, was the straw that broke US isolationism.

Sorry, had to use the old word since we're bringing up Romans. That's the word that gives us "lbs" for pounds. But yes, the typical weight carried by infantry has stayed fairly consistent. As our gear weighs less, we carry more of it and carry the same amount of weight overall. Weight is most certainly the limiting factor. Or at least a major one. There's some others.

I joined the British Army in 1995, and unfortunately / fortunately depending on point of view, I never saw active service. I was occasionally required to do gate guard duty and during those occasions, I was issued 'body armour' consisting of a Flak Jacket. This item was a heavy green waistcoat about 1 1/2 inches thick with a high collar, very similar to the type used by American Armed Forces during the Vietnam War. It DIDN'T contain any hard ceramic plates, and I was told very clearly that it wouldn't stop a high velocity round. IF I was lucky, it might stop a 9mm handgun, or submachine gun, but anything from a rifle would go right through. The main purpose I was told was to hold my remains together in the event of someone throwing a 'blast bomb' at the gatehouse. Really great for inspiring confidence. At least my helmet offered some ballistic protection as it was the relatively new Mk6 helmet!

[@samisuhonen9815]

I used to play escape from Tarkov, and it is a surprisingly realistic representation of body armor. You have all the different levels and materials they are made of. The different areas they cover. And the different types of rounds and bullets in the game, have varying odds of penetrating specific armor based on distance too. Not only that, but repeated hits on armor degrade it, depending on the round that hits it, and how far it was fired from. Then you really see that in a fast paced realistic sim shooter, with a variety of different equipment levels that different combatants have... Strong bodyarmor really makes a difference. It does not make you invincible. But in a scenario where you get ambushed and hit multiple times by an enemy, it is preferable to be knocked out by the first 2-3 rounds hitting your armor, then left bleeding from the next couple that manage to hit your legs or arms, but be able to stop the bleeding and evacuate. When wielding no armor, or just level 1-2 armor, you get penetrated in the body and that's really not good. Also when shooting at an armored target, even if the plate leaves a lot of areas open, those are usually hidden by good firing positions that hide the thighs and feet. And you tend to aim for center mass anyway, in hectic combat. They also train infantry to shoot for center mass, not for the head or other spots. And those center mass hits are usually the most lethal apart from head wounds. So stopping them from happening, increases the chances of you returning home, or even returning to the fight.

Broken ribs? Frankly I'd rather rest and recuperate than rest forever - someone with a broken rib rn

[@AllisterCaine]

I am pretty sure that it isnt broken rips mostly, but dislocated cartilage. This hurts and happens very easily. I did this to myself by pushing my bicycle seat against my breast because the chain was stuck in between the gears. I guess it depends on the size of the plate and the wearer. A bigger plate could just extend over the bony end part of the rips so the whole rip acts as a lever so it breaks at your side as rips typically do. Google a picture of a ribcage and you see where the rips actually are. I really can't believe that hard body armor breaks rips since it dissipates the force very, very evenly. Maybe it only happens if you get hit at the outer edges of a plate just overlapping a bit rip. Sorry for the novel and oversciencing this lol. 😅

[@lemons1559]

@@AllisterCaine Soft body armour doesn't spread the energy as much a you might hope and keeps leaving people shot with small guns with broken ribs. Same's true for plates. If you get shot with something like 7.62x39 or 7.62x54 as many a marine has, they still got broken ribs and collapsed lungs. Those people how ever made it home alive instead of in a pine box.

The one thing Simon didn't explain in that appendix at the end was why Franz Josef was mad at his grandnephew, so much that he was relieved by his assassination. The answer is that Franz Ferdinand was supposed to marry in order to produce an heir for the Austro-Hungarian throne. The Austro-Hungarians were an *Empire*, not a Kingdom. It seems like hair-splitting to us, but Emperors are supposed to have royalty (the families of Kings and Emperors) as spouses, not mere nobility (the families of Dukes, Earls, and the like). The former Sophie Chotek, Franz Ferdinand's wife, was a mere Countess and therefor an unsuitable consort for Franz Ferdinand. His children with her would have been deemed ineligible for the Austro-Hungarian throne, because they weren't descended from royalty on both sides of their families. Franz Ferdinand's (I think) brother, the Archduke Karl (who became Kaiser Karl on Franz Josef's death in 1916) married a Belgian princess. This absurd series of rules regarding Imperial succession is similar to Imperial Russia's; it's why there's no legitimate heir to the Russian throne alive, and why the last German Czar was almost 100% German in nationality. The Imperial Russian house typically looked for wives for their Princes among the German city-states, because many of them were ruled by what was considered royalty.

[@davidnicholas7516]

I said the last German Czar and clearly meant Russian. He was Czar of all the Russians, but German by heritage--almost completely, depending on who got Catherine the Great pregnant...a mystery lost to history...

In 1538, Duke Francesco Maria della Rovere, a condottiero, commissioned Filippo Negroli to create a bulletproof vest. In 1561, Maximilian II, Holy Roman Emperor is recorded as testing his armour against gun-fire. Similarly, in 1590 Henry Lee of Ditchley expected his Greenwich armour to be "pistol proof". Its actual effectiveness was controversial at the time.

I’m disappointed that your research did not uncover the story of Rich Davis, founder of the company “Second Chance.” It was Rich, and his firm, that popularized modern soft body armor.

[@thereefaholic]

How is this video not mentioning Richard Davis? The pizza guy who supposedly invented the bullet proof vest.

[@douglaidlaw1266]

There are actually three common levels of soft armour with two more for military or special threat purposes only: NIJ IIA, II, IIIA, and III, IV, with STP (special threat plates) providing some odd-round protection or in-conjunction-with ratings. Ratings do not take into account soft or hard armour, as you can have level III soft (which protects against 7.62x39 (AK47)), but, yes, level IV is only hard, to the best of my personal experience. I will argue that II or IIA is the most common as that is what almost all of law enforcement uses, and I am fairly confident that police employment numbers surpass that of the military (at least in North America). NIJ is manufacturer independent and must certify all body armour for sale in North America. NIJ has also switched over to a more readable HF and RF (handgun and rifle, respectively) rating. VPAM is the EU rating authority with a lot of different levels, and again does not leave the standard up to the manufacturer. It is NOT manufacturer specific. Plate carriers also are usually made of ballistic nylon, NOT soft body armour. Carriers are by definition just that: carriers. They may have hangers or sleeves for soft armour as well as hard armour, a carrier is just the outer, wearable shell (with attachment points such as MOLLE or Velcro) as sewing on attachment points to soft armour would greatly reduce its effectiveness. Side note: there are also hybrid soft armours that have spike/stab resistance in addition to ballistic. Simon, thank you for the video-it was enjoyed as always. But, for a channel that does so well, and got so much history, how did you miss the present standards and current implementations? Coming from one who wears armour every day. nij.ojp.gov/specification-nij-ballistic-protection-levels-and-associated-test-threats-nij-standard-012300 mehler-protection.com/blog/ballistic-protection-levels-explained-vpam/

[@TheRealAaronSmith]

Another thing to make note of. There is NIJ *Certified* armour, that is samples have been sent to the NIJ for their industry testing standards. It is rather expensive unless you're a large and profitable business, or you're new to the game and wanting to make sure that people will reliably purchase your products and depend on them. Then there's NIJ *compliant* armour, which the company can replicate NIJ tests in-house and rate it according to those standards, but you're taking a company's word for it at that point and that's not a great way to keep yourself alive and in good health if you ask me. That said, armour can easily be built to above NIJ standards, but until it meets a threshold for the next level of armour, it has to be left rated at what the previous level of armour is. So an overbuilt IIIa vest that can stop a 7.62x39 at 100m but not 10m would still be a IIIa. Hence how ballistic helmets are rated, even though they can/will stop rifle threats at extended ranges. But there's no oversight on that. It could be overbuilt by having a single extra layer of kevlar or other aramid, or it could have another 10 layers.

[@BoomDiggety]

Wyatt Earp never got shot. All those gunfights, never even grazed.

[@Peaches-i2i]

Rifle proof plate was used in WW1 and WW2, it was just too expensive. Italian WW1 Farina armor could stop rifle projectiles as close as 100m and weighed only about 20lbs for the chest and pauldrons with a 6lb helmet. Keep in mind these were full power cartridges we'd currently refer to as battle rifle cartridges, something used mainly by snipers/DMRs. The pistol rated Russian armor in WW2 were by comparison only about 7lbs which makes sense since they were given primarily to city fighting troops for building clearing. Modern IBAs and IOTVs with plates weigh near 30lbs. We've never stopped using armor plate, it just got easier to produce. Even today we still use rifle proof steel plates or titanium. It works, with some caveats like spalling and deflected bullets still being hazards. Modern PE plate does good at surviving multiple hits, but it is not as effective as ceramic plate which uses ablation to disperse energy. Most quality plates rated for 3+ are actually ceramic strike faces backed with layers of PE.

That's what I tell people, There is no such thing as bulletproof body armor, just varying degrees of bullet resistance.

[@TJ24050]

The ESAPI (enhanced small arms protective insert) boron carbide plates I was issued in 06 were rated for up to 10 hits of steel core armor piercing 7.62x51mm. Had a buddy take a 7.62x54R round from 100 meters right on the edge of his plate and minus some frag that ended up in his forearm and a sore chest he was fine. They were heavy though. Each front and back plate weighed 8lbs. The side plates weighed 4 and all the extra Kevlar side, groin, and neck collar came to around 13lbs. I see why the guys running dismount patrols in Afghanistan went with plate carriers. You felt safe, but with even a basic combat load you felt the weight quickly. Luckily we were mech infantry so we always had a ride everywhere.

[@alexyoon-sungcucina7895]

I read a story in Newsweek or some such back during Iraqi Freedom about the protection offered by armor. There was one anecdote where apparently some guy got hit by a 30mm cannon round that went off for whatever reason (obviously not fired out of the barrel) and while it smashed the vest and some ribs and some internal injuries, the guy survived. Insane.

​@@alexyoon-sungcucina7895I mean, I believe it possible at the least, whether or not it actually happened or the way it's said to have, I don't know.

[@Nowlan-19]

No mention of modern AR500/600 coated steel plates? Multi-strike rated before frag (not spalling) ever becomes a concern. There's considerably more to modern armor than this covers. Hell, yall forgot about whacky failed concepts like Dragon Skin

[@Riname-K]

Dragon skin still exists under the ownership of Stealth Armor Systems. The reason why Dragon Skin failed was because the design was immature but was bought out by Pinnacle, who would eventually try to push it into military trials. The problem was the original design was never meant for military usage (on top of flexible rifle armor being basically a very new concept) and it didn’t even fit the requirements set by the DOD but Pinnacle still insisted on it all while also cut corners with the test samples so bad as far as using the wrong materials and poor assembly, it was purely incomplete from Pinnacle all around. Obviously Pinnacle failed, and Dragon Skin got the bad rap and controversy it didn’t deserve through the years. Pinnacle would go out of business and the Dragon Skin design would pass through the hands of a few companies who produced it until relatively recently a company called Stealth Armor Systems acquired the design and made updates/revisions to the design including the use of newer modern materials and stronger bonding agents. Here’s the thing though, Stealth Armor Systems is owned and run by the original designer of Dragon Skin and also one of the first or few companies that have a NIJ **certified** flexible rifle armor called Hexar. Now the Dragon Skin design and Stealth Armor Systems is legit and the tech has matured and works, but the issue is whether people actually need such a product because solid multicurve plates have served the world absolutely fine for decades.

[@brianfhunter]

Wait... what?? AR500 steel is really used as armor? when i worked on a metal cutting company, i was tasked to improve as much as possible the quality of plasma cutting when this material first appeared on our company, cutting with plasma wasnt a problem, but the machining boys had a very hard time, it was insanely tough.

[@Riname-K]

@@brianfhunter AR500 was popular in the civilian sector because dealer options for ceramic/composite plates were very limited up to the mid-late 2010s and AR500 was advertised as a cheaper and widely accessible alternative. However a few whistle blowers later, AR500 steel gradually became seen as a risk rather than life saving. The turbulent climate in the US also raised up demand for body armor among civilians which at the same time also raised more dealers providing access to ceramic/composite plates. These days you don’t really see much people talking about steel plates but more demand for ceramic/composite plates.

[@brianfhunter]

@@Riname-K - that makes a lot of sense, our company was producing some sacrificial parts to a concrete mixing machine for a concrete company... 3/4" of normal steel completely sanded of in 3 days, with AR500, the parts would stand at least 1 month of work.
