body armor Strelok 07/27/2020 (Mon) 20:51:09 No.4494
anyone buy kevlar sleeves? I was looking at https://www.superiorglove.com/en/arm-protection/kevlar-protective-sleeves and am not sure what would be a good investment. Other site selling vests only sold gloves which doesn't seem like enough. Also any advice for how to plan to don this stuff rapidly in a safe area in emergencies? Like if there was home invasion with knives? Also wondering if there are any sleeves with NIJIII ratings against bullets since vests only cover torso. I've also read that material in bulletproof vests break down after two years, is that how often you need to buy them? Seems very expensive, wondering if some brands last longer than others.
>>4640 AR500 steel (what you'd use for a steel target) with truck bed liner for anti-spalling, and some extra padding behind it for anti-trauma. For thickness just copy what you see commercial offerings using. You won't be able to bend the steel without degrading its effectiveness though, so you're probably best off covering a small area because a flat piece of steel will be uncomfortable and hard to breathe in. Or instead of using it as portable armor, just use it to armor-up a fixed position for cover. >>4642 Quality pistol and rifle rounds will go clear through a car door FYI
>>4645 >Quality pistol and rifle rounds will go clear through a car door FYI like cutting through hot butter, sure, the point is it's enough to keep HPs from expanding FWIW

>>4646 If that's all you want farmer armor should work as well and be much lighter. Plus it can actually stop very small calibers
>>4651 >If that's all you want nahh, I want something super easy to make at home against stabbing and cutting, defeating HPs is just a bonus though a welcome one. You can live with ball passing through your waist but taking an HP, anywhere actually, bad times lol >heavy clothing I don't know what kind of clothing they tested here but expansion was well within parameters https://www.ammunitiontogo.com/lodge/barriers-and-ammo/ compare that to the effect of sheet metal
>>4652 Look at fiberglass lamnanents. I think a couple of welding blankets and a can of the right epoxy, pressed together with a few tons of force. Is exactly what you are looking for. Could even get exotic and add metal meshes as a few layers. Now you can saw through this kind of stuff. With effort and proper tools. So you could make some different plate shapes.
>>4749 >Look at fiberglass lamnanents. Yeah, it's in the video posted above, thanks nonetheless for the headsup, this is certainly the direction I'll be going. I don't know though how small those plates can be manufactured so as to still give some protection. For a comfortable wear (much) smaller would be better but I'm not sure a system of platelets of say 2" by 4" especially in the shoulder area wouldn't be simply pushed aside even if it didn't break. Now, there's obviously a lot of small stuff that is marketed as bulletproof but I really don't know about the protection it affords. It basically boils down to the question if plates are mainly manufactured the size they are because of economical reasons or if there's indeed a lower treshold below they are useless. Any informed opinions anyone?
>>4568 >Proper chainmail is rivetted together and requires a lot more expertise to work They can also be welded together. Or both actually.
>>4610 >>4630 Sulfur is honestly the least concern. You pretty much need some sort of nitrate, which means you either have access to saltpeter of some sort, or are able to synthesize it, which honestly doesn't seem that hard. And at that point, you're 90% of the way to nitric acid, which means you might as well be making nitrocellulose. I've been looking at the possibility of doing Haber-Bosch -> Ostwald process, the Ostwald process seems to honestly be the easiest way of of making almost any nitrate once you have ammonia, since it just needs O2 + NH3 + a platinum catalyst (car exhaust catalyst), and a bit of heat. Haber-Bosch is pretty easy too, just N2 + H2 + a fuckload of pressure and patience. H2 + O2 can be trivially made in almost perfect purity with electrolysis, N2 needs either an air separation filter or fractional distillation of air, which is probably the hardest part of this whole mess. The rest is just compressors, heat supply, and some pressure vessels, and enough electricity to run the whole affair. Primers are much harder, but if they require too much work, you could probably just use electric ignition without too much trouble.
>>4814 >Sulfur is honestly the least concern Not if you're talking about matchlocks and flintlocks and the like. I don't know if really need it caplocks and modern cartridges obviously don't. >Primers are much harder, but if they require too much work Making primers from scratch would be the touchiest shit ever. Fulminates and azides are not to be fucked with lightly. >you could probably just use electric ignition without too much trouble. But where you get your electricity from? If you're in a position to have to think about making primers from scratch then hopping down to the store to but a 9 volt probably isn't in the cards either. I guess you could make a piezoelectric spark device but I'm not sure how to go about that.
>>4814 Primers are piss easy provided you've got standard book matches. Take standard primer out, disassemble, add matchhead dust with some of the striker tape, reassemble carefully and these you go.
>>4817 >Making primers from scratch would be the touchiest shit ever. Fulminates and azides are not to be fucked with lightly. Thankfully you only need tiny quantities, so I'm more concerned with availability of the feedstocks, but yeah, it's certainly not ideal. >But where you get your electricity from? Honestly could be as simple as a spring powered dynamo or a lead-acid battery in your backpack and a coil pack. Post-collapse I'm assuming electric generation is going to outlast the primary stockpiles of ammunition, since it's going to be a very long time before we're out of alternators and washing machine motors to salvage. Dry cells will probably be depleted before ammunition is, even lithium ion cells will probably be worn out or dead from storage by that point
>>4817 >But where you get your electricity from Solar powered guns? Maybe hook up the dynamo of a crank-operated lamp to your gun to end up with a neo-wheellock look.
>>4820 >Solar powered guns? Growing silicon wafers are to fiddly. >Maybe hook up the dynamo of a crank-operated lamp to your gun to end up with a neo-wheellock look. Now that's an idea. I kind of like that.
>>4754 >size of plates The size of the plates doesn't affect the protective value that they provide. A 4'x6' plate rated NIJIII will provide the same protection as a 10"x12" plate rated NIJIII. Most ballistic plates are 10x12 as that size will cover the vitals for almost everyone, like a one-size fits all (for the front and back). As for armor construction, you want your ballistic plates to at least stop 55gr 5.56 unless you are in an area where that isn't a concern (the ghetto or whatever) I was thinking if you took the fiberglass hard plates from that video above, glued ceramic to the front and a metal plate to the back it could (possibly) stop 5.56 like an improvised SAPI plate
So I've found this https://www.ancient-origins.net/news-history-archaeology/archaeologists-unearth-4000-year-old-siberian-knight-armour-102090 Sorry but no archive >Wayback in september of 2014 in ruskieland, archaeologists reported on the discovery of a suit of armor made entirely of bone, which belonged to an ancient Siberian knight who lived around four millennia ago. >The armor consists of different plates made up of small fragments of bone that have been joined together. Testing is being conducted to determine the type or types of animals that the bone came from, but it is suspected to be from deer, elk, and/or horse. Analyses are yet to determine its exact age but Siberian archaeologists say it dates back up to 3,900 years. >Yury Gerasimov, a research fellow of the Omsk branch of the Institute of Archaeology and Ethnography, said that the bone armor would have belonged to an elite warrior and would have given “good protection from weapons that were used at the time - bone and stone arrowheads, bronze knives, spears tipped with bronze, and bronze axes”. > “While there is no indication that the place of discovery of the armor was a place of worship, it is very likely. Armor had great material value. There was no sense to dig it in the ground or hide it for a long time - because the fixings and the bones would be ruined,” said Gerasimov. >The Bronze Age bone armor is also inconsistent with the style and trends of the Krotov culture, which inhabited the forest steppe area of Western Siberia, and more closely resembles that of the Samus-Seyminskaya culture, which originated in the area of the Altai Mountains, approximately 1,000 km away, and later migrated to the Omsk region. This has led archaeologists to propose that the suit of armour may be a war trophy, or it could have been a gift or exchange between cultures. So this gives me a question are bones usefull as a material for armor? And is there more stuff from this.
>>11365 Bone armor was significantly weaker than basically all of the technologies that replaced it. Bone is relatively soft and brittle, and it degrades pretty quickly. On the other hand, it looks really cool.

https://www.menshealth.com/trending-news/a35110768/us-military-finally-designs-body-armor-for-women/ https://archive.is/USyny >The U.S. military is slowly, but surely, moving to body armor that is comfortable for both men and women, allowing soldiers, sailors, Marines, and airmen of all types to wear clothing better tailored to their gender. >The armed forces are increasing the diversity of body armor sizes and accommodating the needs of the troops, from helmets for those with longer hair to armor that's easier for bladder relief. >The Pentagon, USA Today reports, is responding to growing numbers of women in the ranks—21 percent of the Air Force, 20.2 percent of the Navy, 15.4 percent of the Army, and 9.1 percent of the Marine Corps—by making more body armor options available for female service members. >Sexual dimorphism, a biological principle across all animal species, means human females tend to be slightly smaller than human males. Women and men also have a variety of different physical traits, obviously. The result, then, is that body armor built for men is often less than ideal for women. >This content is imported from {embed-name}. You may be able to find the same content in another format, or you may be able to find more information, at their web site. >The services have all tackled this issue in unique ways. The Marine Corps issues a wide variety of body armor sizes to male and female Marines. The Air Force issues lightweight armor to female airmen specifically designed for women. The Army introduced the new Generation III Female Improved Outer Tactical Vest (seen above) in the early 2010s and has developed a new lightweight helmet designed to fit hair wound into a bun, as well as extra-small body armor for bomb technicians. >Until recently, the military hasn't really addressed the issue of female urination in the field. As a result, female soldiers experienced greater infections and drank less water, making field duty considerably less pleasant for women than for men. In 2016, the Army introduced the ill-named FUDD, or Female Urinary Diversion Device. The FUDD allows female soldiers to pee standing up, without having to partially disrobe. >The new body armor options, as well as new kit like the FUDD, address the reality of a mixed-gender military. More comfortable, better-rested troops who don’t have to worry about where they're going to pee next are simply more effective troops. And more effective troops lead to a more effective military—and a better-protected nation.
>>11657 I still want to know why we let such inferior quality people into the military, let alone ones that need so many accommodations, special versions of body arm, etc.

>>11658 Part of subverting a country is destroying the military by filling it up with low quality soldiers with no real loyalty to the country in question or even a will to really fight at all, and women are perfect for that.
>>11691 Their goal isn't to subvert our countries Anon, it's to destroy them. The Western Tradition and it's traditional Christian mores and ethics are the only things they see standing in the way of their one global government plots and schemes. Any sizable population of indignant Whites are hard to control. Hordes of brown golems -- regardless of their actual numbers -- are easy to control. Your subversion into degeneracy is just a step along the path to your & yours' death. This is their goal for you.
These sleeves are designed for security use, to protect against mainly knives- but also abrasions because open cuts present a HIV risk. But you will find many garments that are slash proof to varying degrees. I have one knifeproof jacket that is made out of a natural cactus polymer fiber. I have one jacket that's full skin leather. The problem with these is that other people can grab them, and when you are dealing with multiple assailants that is a huge deal. A lot of these sleeves are fake though, being expensive and sold online to largely uneducated consumers.
>>11658 Part of it is just decadence. The US hasn't really directly fought an equal power in an unlimited war since World War II and we've spent the past 40 years just playing in the Sand Box. We don't have any expectation of having to give anything close to 100% of our military to any sort of war effort. None of the wars that we're in of have been in for decades really mean anything and even outright losing any of them wouldn't be an existential treat to us. In that sort of environment foolishness and boondoggles breed like rabbits.
>>4630 If civilization really goes down the path of the collapse of all logistics, where reloading is gonna be niggeriging accidentally found materials and coping with a limited supply of spare parts, investing in autarc manufacturing capabilities would be your first hurdle. Back to basics, machines can break too. To leave out an awful lot that could be written here, maybe a return of needle rifles, but even getting a more primitive black powder and musket production up and running may be hard enough to be quite honest. I may seem pessimistic, but when was the last time anybody actually began from scratch when tinkering with their funs, and by scratch I mean the beginning of the Iron Age. Everything is bought from the store or online. That should be invested in, to be able to restart civilization and defend it. Very primitive stuff by today's standard, but almost rocket science for somebody thrown into the big shit.
>>14160 We have the distinct advantage of knowing what works, but somebody should really organize that knowledge, and also try out in practice if it can be done. Realistically speaking, the greatest problem would be to keep the basic units of the metric system accurate enough to rebuild it. But a much greater problem is that it would be too great of an effort, and you'd have to teach it to enough people that at least a few of them are going to be able to go through it if needed.
So I understand actual rifle plates but what difference is there in soft body armor? I want a concealable, stabproof, IIIa vest but don't know all the differences in tech or reputation of these companies.
>>14762 >So I understand actual rifle plates but what difference is there in soft body armor? Soft body armor and stabproof armor are two different things. One is a vest made of kevlar(or similar fibre) to stop small bullets, but they are not stabproof. The other is usually made of thin hard plastic/steel plates to protect the whole torso against cut and stab attack, but they are not bullet proof. Combi Vest with the abilities of both are made, usually for police. Look for armor that is certificated by offical governmental rating organisations to find trustworthy companies.

>>14762 In the future it's all going to move towards specialized polymer vests that rapidly reduce impact while being cut-resistant, but as of this time those are still expensive, so stab-resistant and bullet-resistant are not the same thing. "Stabproof" clothing options are designed to resist cutting/tearing/splitting but typically do little in terms of acute impact resistance past whatever meager padding has been added. Defensive "bulletproof" vests rated II or lighter (such as Kevlar) rely on dispersing the kinetic energy of the projectile over a large surface area so as to prevent it from going into your soft squishy body, but this means they're fairly worthless against rifle rounds which are more of a "piercing" round designed specifically around this body armor flaw (which is why rifle calibers are great for hunting boar, bear, moose, etc. since those animals have thick "bullet resistant" skin and hard points). This isn't considered a design flaw because typically these sorts of vests are to prevent being killed by a concealed firearm with less kinetic energy behind it, where it will hurt when you're shot but it won't cause much more than bruising. Plates ("level III and better") are the opposite in that they are designed to prevent deformation upon impact, but because of this they lack many of the features of "bulletproof" armor that people find desirable such as dispersing the impact over the surface of the protected area (E.G. you will still get blunt trauma without padding underneath). It's also heavy as shit because typically you're dealing with metal or ceramics. This makes it useful for defensive positions or specific applications, but it's typically a situation where it will only protect you once, for a high cost, and then it's worthless or its value has heavily reduced. IIIa is a meme. It tries to be the best of both worlds but is in fact the worst of both. It fails to provide the same level of protection as plates while also failing to reduce the force of impact like II/IIa armor does. There are exceptions to this rule beginning to come out, but you're looking at spending over a grand for one of those exceptions and it's anything but concealable. Depending on application, either a chest rig with III+ plates to protect your organs (very explicitly noticeable) or a II/IIa undershirt or jacket is the most ideal solution that will provide protection without reducing mobility. In your specific case, I would combine a a II/IIa tank top (these run for $100-$300 depending on brand and weigh about 10lbs) with either a welder's/construction jacket or a set of coveralls. That setup will blend into most establishments by making you look like a hick or tradesman, and welder's/construction jackets/coveralls can be bought with stab resistance, shrapnel resistance, and flame retardant properties for about $60-$150 depending on brand. Just keep in mind that there's a difference between flame retardant fabrics and clothes treated with flame retardant chemicals since most common household detergents and dryer sheets will strip flame retardant chemicals from your clothes. I believe borax and simple green are both safe, those are what I used when I had to wear flame-retardant (treated) coveralls that got hella filthy, but don't quote me on that.

>>14765 Thanks. I thought IIIa was basically the same as level II/IIa stuff but able to deal with slightly more powerful pistol rounds. Is there anything I need to know about the construction of these vests like how ceramic rifle plates can have thick padding around the strike face to lower weight and have it compare better on paper? Maybe that's the construction difference between IIIa and II/IIa?
>>14160 If Civilization goes to shit to such a degree, you shouldn't worry about firearms anymore, but about actually getting shit done. And bows and crossbows get shit done. Guns are only needed if you're in for a really big fight, and even then, you could fuck up a reasonably big enemy force by using traps and ambushes. BUT I WANT ME GUNZ Well, in that case you better hoard pdfs on the basics of science and basic chemistry, physics and engineering, because those will come in handy. Tables and charts for specific calculations too. and don't let them stay digital, print everything out, on good quality paper, bind it and keep it dry and cool. You will need every scrap of knowledge for rebuilding civilization, and therefore, guns. >>4814 Sulfur is fucking hard to get, if you don't live near a volcano or a hot spring, you're outta luck, because fucking around with extraction of sulfur from minerals is pretty high on the industrial ladder, and when you manage rig a contraption to condense evaporated sulfur from melting minerals, you may just as well relocate to an area with volcanic activity and work with abundant natural sulfur deposits. As to saltpetre: stack shit and piss with separating layers of straw, let it rot, and then wash the whole stuff with water, which you then mix with potash, boil it off and let the saltpetre crystallize. done. That way you get a pure enough product to make a good gunpowder.
>>14767 Isn't diesel fuel fairly high in sulphur? I thought that was the main byproduct produced when trying to extract platinum from a sawed-off catalytic converter? Match heads are sulfur mixed with potassium chlorate if I remember correctly (that's why you can mix them with sugar to make explosives for those toy rockets).
>>14768 Not the anon, but I think he forgot that sulphur is the main byproduct of crude oil distillation (i.e. oil refinery). It's probably a good idea to start there. Though it's not crystalline sulphur, but hydrogen sulphate, so you would need to separate it somehow, and at that point you could just as well just burn it and use it to synthesize sulphuric acid. As to matchheads, sulphur hasn't been used since... The 1950s I think? It's been replaced with red phosphorus which, instead of being part of the matchhead, is now part of the striking surface of the matchbox. Chlorate is right though.
>>14767 >Sulfur is fucking hard to get,... The only reason Sulfur was in gun powder was to lower the ignition temperature of the saltpeter/charcoal mixture of black powder. If you use another mixture for gunpowder that has a lower ignition temperature or simply use a stronger ignition system in your rounds/gun(like electricity) Sulfur can be left out.
On the topic of more primitive firearms, tubelocks seem to be a quite interesting option: https://invidious.kavin.rocks/watch?v=v_Iyl-Tnjgo https://invidious.kavin.rocks/watch?v=fmGckpMx1sI

>>14767 >>14768 >>14800 I've actually wondered if there's enough sulfur in coal to suffice for gunpowder? >>14948 Well if you're in an after the collapse sort of situation you probably aren't going to be building guns with fancy electric ignition systems. More likely you're going to be be making matchlocks and flintlocks instead.
>>14993 Not really. Also, charcoal is used for gunpowder, so pretty much nothing but carbon. Honestly, firearms aren't even the best option after a complete collapse of civilization. High tech requires high tech maintenance, and if something breaks, replacement parts are hard to get. We could survive a few decades on supplies of parts and ammo, but if you think long term, falling back on more primitive weapons is inevitable. If firearms prevail though, we will definitely see a fall back to the old practice of hand-fitted guns, every single piece being unique. Back on the topic of ammo: the hardest part isn't even the propellant, but the primers. Do you guys even know how highly sensitive explosives are made? Even the oldest primer explosives, fulminate, require either silver or mercury, nitric acid, and pure ethanol to be synthesized, and then you still need equipment to safely do it. And that's only the most basic, corrosive explosive for primers. >>14948 You're right, but an electric priming system is hardly enough for ignition of sulfurless powder. It can be ignited, but you would need to provide temperatures of about 500 degrees Celsius to ignite it, as otherwise the reaction will not start. If memory serves me right. On another note, what about pneumatic guns? The technology for making rubber and sealants is out there, and probably won't be forgotten for a long time, and high-pressure rated metal parts are all out there, in plumbing and and heating, so it seems like a logical step to concentrate on making guns that rely on compressed air, especially since you could automate the process of refilling air tanks by hooking them up to a compressor, and use wind generators to power it. Very sustainable if you ask me.
>>14993 >Well if you're in an after the collapse sort of situation you probably aren't going to be building guns with fancy electric ignition systems. Batteries are cheap and everywhere, every Nigger owns a Powerbank for his Smartphone or Tablet. Even with a war or economic problems that whipes out the indutry of cheap electronics it will take decades before they are vanished from society. >More likely you're going to be be making matchlocks and flintlocks instead. Anon the most common weapon on the planet is the AK47, a gun that is even cobbled together in 3rd world countries by Niggers living in dingy huts without elecricity. Even with a collapse of Western Civilisation be it economic, racial, pandemic or from total nuclear warfare this knowledge of guncraft will not die out, because it is so wide spread. The guns of an after collapse world will look like the guns cobbled together by the criminals of Middle and South American Favelas or the guns produced by the Resistance in Europe during WW2, but we will not go back to match- and fintlocks. >>14995 >You're right, but an electric priming system is hardly enough for ignition of sulfurless powder. It can be ignited, but you would need to provide temperatures of about 500 degrees Celsius to ignite it, as otherwise the reaction will not start. The temperature depends on the powder mixture. You don't have to use potassium nitrate+nitrate to get a gunpoweder. The advantage of the electric priming system is that you don't need a chemical primer, the powder you ignite just needs to correspond to the heat your electricity source can produce. One could even use little lightbulbs as primers, the lightbulbs without the glass gets into the cartridge so that the wire is exposed and in contact with the poweder and the firing chamber of the gun is so constructed that its just making contact with the contacts of the lightblubs.
>>14995 >Back on the topic of ammo: the hardest part isn't even the propellant, but the primers. And that limits not only the use of modern auto loaders, but also the likes of caplocks, pinfire, needlefire, etc. as well. >>14998 >Anon the most common weapon on the planet is the AK47, a gun that is even cobbled together in 3rd world countries by Niggers living in dingy huts without elecricity. It's not the guncraft that's the problem, it's the ammo. You can't really run modern style guns on BP for long and smokeless is a lot harder to manufacturer on a post apoc cottage scale. >One could even use little lightbulbs as primers, the lightbulbs without the glass gets into the cartridge so that the wire is exposed and in contact with the poweder and the firing chamber of the gun is so constructed that its just making contact with the contacts of the lightblubs. It's hard enough to find micro lamps as it is now, to say nothing of after the collapse.
>>14998 the question isn't about the primers, it's more about the propellant. The ignition temperature of the mixture has to correspond to the maximum temperature of the priming system. If your primer can't reach the needed temperature, the reaction won't happen. Either that, or your lock time increases, because the "primer" needs time to heat up. >>15001 >smokeless is a lot harder to manufacture on a post apoc cottage scale. indeed, although, if you do manage to obtain sulfuric acid, nitric acid and glycerine in sufficient amounts, you could most definitely make cordite at home, the very first smokeless propellant.
>>15001 >You can't really run modern style guns on BP for long and smokeless is a lot harder to manufacturer on a post apoc cottage scale. 1. You don't have to use Blackpoweder as gunpoweder. 2. Smokeless gunpoweder was first produced in 1884. Even with a collapse we will not fall back into a world that is more primitive than the 19th century. >It's hard enough to find micro lamps as it is now, to say nothing of after the collapse. You can buy a package of 50 oldschool micro lamps for 10€ off from Amazon here in the EU. Even my local hardware store still has them. Buy some packeges now, together with some metal tubes, ring washer, lead and a welder and you have everything to produced bullets in the after collapse once your normal ammo runs dry. >>15002 >The ignition temperature of the mixture has to correspond to the maximum temperature of the priming system. If your primer can't reach the needed temperature, the reaction won't happen. Either that, or your lock time increases, because the "primer" needs time to heat up. I know, but you guys forget the simple fact that we live in the here and now and at this moment of time there is an entire industry shitting out millions of Jet Flame lighters and Electric Arc lighters every month, they cover entire walls at local big stores together with the needed lighter fuel. If the collapse comes, you just have to get your hand on one of these things and integrate it into whatever gun you are building at home. These ligthers get really fucking hot and easily ignite whatever gunpoweder you throw together at home, even if its just sugar+potassium nitrate. Stocking up on ligthers isn't even a stupid thing for a prepper as they can be used for bartering. There are dozens of ways to build guns and ammunition for them, you just have to plan and test which is the best way for you before the collapse happens.
>>15010 >Smokeless gunpoweder was first produced in 1884. Even with a collapse we will not fall back into a world that is more primitive than the 19th century. It's not so much a question of it being beyond knowledge as it is being beyond means. I imagine that back in 1884 the smokeless that was being manufactured in major industrial centers and then distributed from there. It wouldn't have been like someone discovered the secret of cordite and then every little frontier town had a chemist that could produce a 1000 rounds per month in his little one person shop.
>>15017 Spot on. Even for cordite you need nitric and sulfuric acid, glycerine, cellulose and a jellying agent, usually petroleum jelly. And then you still need the equipment to synthesize the nitroglycerin and nitrocellulose, which you need for cordite. Then you will still need to mix the stuff, and extrude it into cords, dry it and chop it into appropriate pieces. Logistics are again the core problem of everything.

Elmer Fudd ought to become the new mascot of the armed forces. Makes sense to me. >new body armor options, as well as new kit like the FUDD, address the reality of a mixed-gender military. More comfortable, better-rested troops who don’t have to worry about where they're going to pee next are simply more effective troops. And more effective troops lead to a more effective military—and a better-protected nation. Horray I guess? Thank God there are no other problems in the world today. That piece is unintentionally amusing I confess. Still waiting for a catastrophe to happen like what the Norwegian navy had to wade through. https://archive.ph/BaoSi (link related, a classic. Bonus points at the end, acc to the article they had no insurance (didnt know that, wtf.) >>11659 Don't forget you need a shiny navy too. Go for rugged oil tankers (ice class strengthened), pack a fuckton of missile artillery on top, and if nothing else does help - go Tegethoff on them. Tegethoff - not Hasselhoff. Remember this.
>>19756 > 21 percent of the Air Force, 20.2 percent of the Navy, 15.4 percent of the Army, and 9.1 percent of the Marine Corps. Yet they fail to mention the even greater menace in the ranks in even greater numbers, janny furfags.

>>14995 >On another note, what about pneumatic guns? ... They trialled some in about 1800 with the Girandoni air rifles, so called Windbuechsen back then. You may have heard of them. One problem was reservoirs needed to be refilled in the field, either exchange empty for filled (like with mags), or send someone refilling behind the line of fire. You have no time to pump 'em up right there and then. They made handcranked compressors on carts to refill a handfull tanks at once iirc. The empties are brought back, full ones given to the troopers. The tanks need to fit well for this to work, like magazines one could use on another, similar gun. You cannot have tanks to yourself/for your gun only. Imagine the nightmare. Tanks could start leaking, which will render them unusable till you can fix them. Somewhere to the back. Also the rifles were manufactured, literally handmade. Lots of handfitting, something we can do smarter now I say. And they were finnicky in general, not very robust. Could be solved today (also if SHTF). We have advanced from 1800s to nowadays, and I believe we could overcome some of the challenges. You need e.g. to compensate for power decline as the air reservoir is emptied. To be able to hit targets until you run out of air, or bullets, which comes first. The tank needs being protected, so fit into the rifle, the best way. Exchangable buttstocks. Also a rugged simple twist-lock mechanism, lugs like how you mount bayonets. So yeah, is a thing, can be done, but as a first choice I'd rather prefer other proven solutions tbh. Range was over 100 metres/110 yards, and they didn't use true pointed projectiles, only the literal bullets or 'musket balls', not even Minié types. Reminder, 1800. When Napoléon ran out of chewing gum. So there is wiggle room for improvement too. Perhaps up to 150 metres/165 yards, seems feasable. Similar to shotgun (with slug, rifled barrel, in it's role as a musket - how ironic). But definitely more silent I think. Should be a plus, shouldn't it? https://ytb.trom.tf/watch?v=NPHPYN0NPGE (vid related is review of 'portable' compressors, the smallest is still huge as fuck.) To me it boils down to is it uncomplicated/reliable to use? Similar to the question of battery driven car versus fuel driven car. We got used to liquid fuels, they are great to store for a while, easy to transport, and it just takes minutes to refill even a big car tank. Who wants to literally stand by, waiting for half an hour and more to charge a car battery? Even if you only had to do it every few hundred kilometres/miles? Me not. Is why alcohol and fuel cell is the right thing imho. >Fill tank, produce electricity on the way, use for traction motor(s) and whatnot. Do not get me wrong pls: For fixed routes, battery-electric cars/busses/trucks and water/air/railway vehicles are alright. Like it's done with public transport of goods and passengers. They did use some in the past (e.g. German battery-electric railcar, the Wittfeld-Akkumulatortriebwagen of 1907, in service for half a century(!)), and are using boats reliably for a time now, too (a modern one is the MV Ampere catamaran ferry in Norway, since 2014 afaik). >Charge, takes a time, but you do it once a day. >Then you run the vehicle all day long. >During evening/in the morning charge again. >Rinse, repeat. This can work fine, but those vehicles in use are rather not extended-range ones. Same goes btw for compressed-air driven vehicles (little motorbikes for transporting pizza a.o., compressed-air 'fireless' locos, as shunters - awesome, no kidding). You need a compressor placed somewhere, nothing I want to take with me all the time. Or how about classic steam-engined ones, which you need to bring to temperature first - and not let them cool down else you wait. Sounds familiar? For an 'if you need to, move on - quickly, to anywhere' style of travelling it's a no-go, literally. Sorry for the long rant...

>>14995 >It can be ignited, but you would need to provide temperatures of about 500 degrees Celsius to ignite it That problem has already been solved by Daisy back in the day. They claim a temp of 2000 degrees Fahrenheit or 1093 degrees Celsius for their firing mechanism. The projectiles use a block of smokeless powder with a claimed velocity of 1150 fps for what is likely a 25 to 30 grain projectile. It would take some doing getting the air to compress and heat properly as it uses a unique obturator to do so, but not impossible to do and a patent may exist removing that work.
>>11365 I reckon you could make a serviceable piece of slash/stab/blunt trauma resistant armour using the technique shown in the bone example and only the thick rubber and steel wire found in waste tyres.
