    Since nobody got it, I'll finish this one off. It's the Martel "Mechanical Coffin". Page 47, David Fletcher's book "Mechanized Force: British Tanks Between the Wars". Martel had created some of the early tankettes in the late 1920's, but after a while, he decided those were too big. So he created this silly thing. A soldier was supposed to lay down in it and drive forward. Once he got close to the enemy, it had a lift up panel he would use as armor and fire his rifle through.

    Since Xlucine suggested it in the general AFV thread, here is a new version of the old Tank ID thread that used to exist at the WoT forums, back before the great exodus to SH. The rules are simple. Post a picture of some sort of AFV and everyone has to try to name what it is. Try to avoid posting a new picture until the previous picture is identified. Generally, the person who was first to correctly ID the picture in question gets to post the next picture, unless they want to pass. If a picture is not ID'd in a day or two, the person that posted it should say what it is and bask in their own sense of superiority. They should then post a new picture for the sake of keeping the thread moving. Please, no fictional tanks, paper napkin drawings that never made it to prototype or pictures where the vehicle in question is obscured or particularly hard to see. Also, if posting a picture of an unusual variant of a relatively common vehicle, be sure to note that you are looking for the specific variant name, not just the general family of vehicles it belongs to (for example, if I post a picture of a Panzer IV with the hydrostat drive, I would say in the post something like "What makes this Panzer IV unusual?" since everyone can ID a Panzer IV) It is perfectly ok to shame those that make spectacularly wrong guesses. That's just how we roll around here. I'll start

    The ELKE test bed like many of its experimental cousins mounted the ARES "Super 75" 75mm main gun. This was an impressive gun with performance above and beyond what was expected from it's size. Here are a few pics of the Super 75 APFSDS round being live-fire tested against a fully loaded T-54...

    If The King in Orange wants to gaslight the Republican Party, I'm fine with that. Fuck those people too. Honestly, the back and forth in this thread seems to break down like so: A:"Guys, I'm worried that Trump appears to be exhibiting a repeated pattern of trying to damage institutions and traditions, embarrass officials, and glibly dismissing any criticism with a series of baffling and nonsensical one-liners that he clearly improvised." B:"FUCK YES THAT'S WHAT I VOTED FOR! IA IA, TRUMP FHTAGN! HAIL THE ALL-CONSUMING MADNESS AND MAKE AMERICA GREAT AGAIN!"

    I agree that the majority of the US population won't rise up in anger against this latest outrage, and that in a surprisingly short span it will be only vaguely remembered. I disagree that this is due to American politics being filled with latter-day Julio-Claudians, although if you are correct I eagerly anticipate full political representation for horses. Here's the deal; the US/Mexico border is fucked up. It's not just fucked up, it's completely fucked up. Trump is offering a solution, albeit a... somewhat harsh one. His opponents are offering... nothing. The Democrats haven't even cynically put forward an alternative bill that they don't really plan to pass. They learned their lesson when Trump ended DACA. Trump likes to highlight issues that are divisive for the Democrats. If they say anything substantive they will be beaten black and bloody by their own base. If they say nothing at all, they will be beaten by their own base, but less severely. The emptiness, the lack of long-term memory that you identify is part and parcel of being an anti-Trump politician today. Those poor bastards sure do talk a lot, but they don't really do anything. Trump has successfully traumatized all politicians who are not part of his agenda into metaphorically assuming the fetal position and drinking the pain away. Or perhaps they do that literally. They do complain a lot, but nobody cares about the complaints of politicians because politicians aren't people and when their feelings get hurt it's funny. Seriously, supposed anti-Trump leaders are really that feckless. Their latest master plan is to harass Trump Administration employees in restaurants. That'll teach 'em! Trump is surely finished this time! On the order of tens of millions of migrants cross the US/Mexico border every year. I say "on the order of" because the thing about undocumented immigration is that it's undocumented, so the error bars here are pretty big and nobody has a crystal-clear view of what's going on. Remember when your country was having all those refugees from Zimbabwe, who largely ended up stuck in camps because there wasn't much else to do with them? Now, imagine that half of the population of Zimbabwe crosses your border every year. Some of them stay, some of them go back. Some come in seasonally. The situation is largely driven by economics. As you might imagine, a completely unregulated, mass-scale enterprise like this leads to a free-market, Libertarian paradise. It includes all the traditional paradisaical elements of gangsters who prey on immigrants, mysterious mass graves, child prostitution, and weapons smuggling networks that somehow extend to Islamist groups in Europe. I'm not usually one to say that a situation is so morally outrageous that something must be done, but holy shit, they should probably do something about all this. Note that the article on the mysterious graves also notes that children were put in detention camps. Trump is sorta-kinda telling the truth when he says that putting children in cages was the previous administration's policy. It's just that whenever there was a large pulse of migrants, previous administrations would blink because they feared the bad optics of putting children in cages. Trump doesn't give a fuck, and ordered full steam ahead. Or, more likely, immigration hardliner Stephen Miller told them to go full steam ahead. You may wish to imagine that he swirled a twelve year old Grand Vin de Chateau Latour around a gilt human skull while he did this, but like I said before, I think the Trump Administration folks largely see themselves as men of the people, so it was more likely a mid-grade California prosecco. Trump's gamble has largely paid off. Americans are angry about children being separated from their families at the border, but more of them blame the parents than blame the Federal government. Again, we see that Trump's divide and conquer strategy succeeding generally.

    Been delayed with stuff but I've wanted to post this. Actually I'm surprised I've never seen anything in detail about this before, because it's an interesting topic. (IF there IS a topic on this I apologize and it can be merged there.) ETC tech is something you probably hear about if you hang out on tank, military or gun forums. Especially if Railguns or coilguns are mentioned. Or 'next step' in gun design like 140-152mm guns. There's lots of information out there if you look and you discover just how diverse it can be. I'm sure most people are aware that Wikipedia has a article on ETC tech and as far as Wiki articles go it's decent. But the person who worked on it in the past also wrote an article on ETC for the Nationstates draft room. It's old but still good. So despite the origins it's still useful (the writer was also a member on Tanknet IIRC. Take that as you will.) In Jane's Technology of Tanks, Ogorkiewicz also commented about ETC: Ogorkiewicz also discusses the concept in Tanks: 100 years of evolution: One realization from this is ET/ETC technology is quite diverse and can be confusing. One of the better sources covering that concerned Rheinmetall research into a German 120-140mm (courtesy of Wayback because the original source fell to link rot): Link to image of Rheinmetall ETC classifcations On the amateur experime which discusses ET/ETC stuff in detail too. If you prefer the more 'hype' side of things, ETC was also tied to the Future Combat Systems - a link some people may recognize: As you can see, ETC is evolutionary not revolutionary like EM guns. It takes existing technology and builds on it: You can settle for improving propellant ignition (minimizing electrical cost) or add electricity to boost performance (up to the 'pure' ETC idea) You can also utilize the technology on Liquid propellant and possibly even Light Gas guns - it stacks quite nicely with other ideas. You can even use it with a bigger caliber. This is part of the ETC charm. Further information on ETC stuff can be found here: AN END-TO-END MODEL OF AN ELECTROTHERMAL CHEMICAL GUN Electro-Thermal Chemical Gun Technology Study Both of these are articles I like, but there's more stuff: Electrothermal-Chemical (ETC) Technology Weaponization Issues Electrothermal-Chemical Gun Systems Utilizing Novel Electric Solid Propellants And of course DTIC is a wealth of ETC stuff: (direct pdf links): Overview on the German R&D Programs on ETC Gun Technologies for Main Battletank Weaponization ELECTROTHERMAL-CHEMICAL PROPULSION AND PERFORMANCE LIMITS FOR THE 120-MM, M256 CANNON And some dtic links to ETC stuff that requires download: Electrothermal-Chemical (ETC) Propulsion with High Loading Density Charges. Ballistic Analysis of Electrothermal-Chemical (ETC) Propellant. Trade-Offs in Performance Enhancement of Solid-Propellant (SP) Electrothermal-Chemical Guns. Sturgeon's House user sevich also posted a link to a useful ETC document off ditc here

    Abraham Maslow's later work was really weird. We briefly discussed this interview on the Discord server before, and I think I did a poor job1 of explaining why this interview reveals so much. So I will try again. What makes this piece interesting is not the interviewer. In fact, the interviewer is so bad at their job that I want to reach through time and space and (attempt to) beat the stupid out of them. I mean, look at some of this shit: What possible point is there to asking these questions? Either Brad Parscale was part of a massive criminal conspiracy with the Russians to undermine the American electoral system, in which case he would say exactly what he said above, or he wasn't, in which case he would say exactly what he said above. What possible purpose could this serve? I want to know what is wrong with this person. Brian Blessed wants to know too. Ignore all the parts of the interview that are about this shit. It's obviously pointless. Fortunately, the fact that the interviewer was too unprofessional to avoid wasting everyone's time with idiocy did not prevent Brad Parscale from stating what he came to the interview to say: OK, you got that? Facebook was the centerpiece of Trump's campaign and eventual victory. It's all about Facebook. That's what the Brad-man is here to say. You understand that message? OK, now ignore that part too. This is obviously misdirection by the Trump campaign. Social media services come and go. By their nature, they tend towards natural monopoly, so only one is really dominant in a given region of the world at any particular time. But Facebook sits atop a throne made of the bones of Myspace, Friendster, and a bunch of other dead services. In time, some new upstart will add Facebook's place and add its bones to their regal seat. There is nothing particularly magical about Facebook. They have risen and they will eventually fall. Furthermore, there are signs that their inevitable decline will occur sooner rather than later. The fact that their founder got dragged before the US congress and forced to explain technology to a bunch of senile muppets is one such sign. Getting the Democrats to commit hard to a theater of war that is already losing relevance would be a very Trump move. Alternatively, the interview reveals just how incompetent Hillary Clinton's Facebook team was: It's entirely possible that the Trump campaign is baiting the Democrats into committing more resources to a theater of war where his side is so effortlessly superior that they would just be wasting their money. But honestly telling people what his strategy was is so obviously bait that it can't be wise to take the idea that Trump won mainly as a result of Facebook literally. No, what's really interesting about this interview is that it shows how technology will change politics: The Trump campaign used, and is using (Trump never stopped campaigning) the power of the eldritch outer god of Evolution. If you know anything about Evolution and all its manifold horrors, this should scare you. But it did not scare the interviewer, as they possess that singular trait that keeps mind-shattering cosmic horror at bay: fucking ignorance. This interviewer thinks that Brad Parscale might have used black magic mind control, and this prospect is clearly disturbing to her because she is worried that evil men might connive to mind-rape people into voting for Trump. This is about the worst possible crime that this interviewer can imagine anyone committing. In fact, what Brad Parscale admitted to is far worse and the interviewer is too fucking inbred to notice. If psychographics, theoretically speaking, weren't a pile of horseshit and it were possible to mind-rape Facebook users into doing the bidding of an evil overlord, then at least the depravity Facebook users would be subjected to would be limited by the imagination of the evil overlord. Evolution is, by definition, not teleological. There is no design behind it. It just oozes by trial and error into every nook and cranny of the possible. The possible is a much larger set of unspeakable cosmic horror than the merely imaginable. The human mind came up with the works of the Marquis de Sade. Evolution came up with parasitoid wasps. Unchained, self-modifying optimization routines will do awful things that their human minders would never think of. Read this account of a coder who accidentally created a racist AI that affirmed local bigotry in a language the coder wasn't even fully literate in. That is the horror of adaptation. Evolution isn't malicious. It's much, much worse. This is just the start. In the long term, the human race is doomed to being manipulated by smart ad-bots into doing nonsensical, debasing things. Not even cynicism will protect us, no more than the potent insecticide nicotine protects the tobacco plant against tobacco hornworms. Evolution is going to torture us all for no reason forever and there's nothing anyone can do to stop it. I don't blame Brad Parscale, just so we're clear, but I would like the record to state that Trump was one of the first to enlist the aid of the outer gods in order to secure a political victory. Self-refining ads will be much, much worse than psychographics, because eventually trial and error will evolve something like psychographics that actually works. Human attention is up for grabs, and inevitably it will be captured by self-refining artificial intelligence. AI will figure out how to make ads that are more attention-grabbing and more addictive than gambling and pornography. If you want a vision of the future, imagine a small orange robot hand grabbing a human pussy - forever. Of course, everyone knew that robots would kill humanity, or worse, eventually. But a direct revelation on the exact methods they will use is a rare treat. But I realize that not everyone is a connoisseur of robo-eschatology. So I have saved my explanation of the most exciting disclosure from this interview for last: The part bolded above is why it doesn't matter if Facebook explodes tomorrow. Facebook, Google, the Kroger family of supermarkets; all of them work the same way. If a service is free, the user is the product. Services that have created mass databases of personal information have been around for years. A combination of social networking services and automation are making it possible for political campaigns to take advantage of these databases in ways that they could not previously. It is now possible for a political campaign to efficiently attack weaknesses in an opponent's coalition that were too obscure and diffuse to attack before. The traditional political coalitions will not survive this development. The ability to make targeted campaigns to small, dispersed swing demographics puts long-tail candidates on a much more even playing field with more traditional candidates. It has already been pointed out several times here that Trump's campaign in 2016-present wasn't so different from Ross Perot's in 1992. But Trump had, among other advantages, the technologically-assisted ability to get his small hands into crevices that others could not take advantage of. He has enjoyed several other advantages, like the ability to just shrug off manufactured outrage, to electrify crowds with postmodern Charlie Sheen mantras, and twenty four years for Bill Clinton to lose his edge. However, this technologically-enabled micro-targeting should be more interesting than these other advantages because it's an advantage that someone who isn't Trump could use. In short, it's a fulfillment of the prophecy laid out in this surprisingly good Newsweek article from ten years ago. I have no idea what happened to that author, by the way. They seem to have been able to write coherent articles, and yet they still worked for Newsweek. Presumably the management had them executed. 1. i.e. everyone else made a subpar effort at comprehending my brilliance

    The age of these simulations doesn't change a number of facts: when seen from an angle, the surface area behind which the crew compartment is located is greater on the Leclerc the turret bulge, gun mantlet and gunner's sight are weakspots in the armor layout that remain existent even in the more modern Leclerc variants the Leclerc's armor is physicially thinner Yes, the current models of the Leclerc (and also the Leopard 2) use much newer armor inserts than tested in Sweden; however that doesn't guarantee that the Leclerc will reach or exceed the protection level of a modern Leopard 2. Given above points, the Leclerc could even be considered inferior protected, if its armor offered a higher protection level per weight and thickness (which I doubt given that the Leopard 2A7 features new armor inserts). That's frankly a lie. Just like the stupid lie from Froggy on the SteelBeasts forum about the Greek military using the AMX-30B2's armor to simulate the Leclerc's protection level. It is stupid to lie just to pretend your favorite tank/toy is perfect, that is not true. Nobody buys a tank without knowing how well its armor will perform. Sweden was supplied with performance data (or protection level estimations) of the tanks and tested armor modules to verify that the data was correct. These tests were not necessarily done in Sweden, for example the M1A2 Abrams' armor was tested in the United States in order to ensure that the exact composition and layout of the armor array remained secret. The Swedes supervised the armor tests in the US and brought their own reference threats (i.e. two types of APFSDS, two large calibre shaped charge warheads to represent ATGMs and one smaller shaped charge to simulate the HEAT rounds fired by the Carl Gustaf recoiless rifle). We know from Swedish sources, that the M1 Abrams with Swedish armor package provides a much higher level of protection than the one seen in the comparison chart: Note that the M1A2 turret is shown with the original armor package! We also know that the Swedish armor was designed to meet the requirements (best possible protection against APFSDS with 700 mm penetration and 165 mm shaped charge warhead along the frontal arc of the turret). The Leclerc shown in the comparison chart clearly fails to meet this requirement, therefore it is not the one with enhanced armor protection. Last but not least we know that the Swedish armor was designed as add-on armor and that the base armor of the tank was kept. Therefore your claim that the comparison chart showed the Leclerc with Swedish armor package would mean that the basic Leclerc's armor would be a lot weaker. The add-on armor would replace the storage boxes at the side of the turret while adding a wedge-shaped module (like used on the Leopard 2A5) to the turret front. The Leclerc at 54.5 metric tons was designed to reach a similar level of frontal protection than the Leopard 2A4 (pre-1991: 55.15 metric tons) and the M1A1 (57 metric tons). It did so, while being lighter, having a bigger gun and having more side armor. To expect that a 54.5 tonnes tank would reach a protection level even broadly similar to MBTs with a weight of 62.5 tonnes (M1A2 and Leopard 2A5 prototype) is silly. You are misinterpreting the news. The contract between France and Germany only decided that the MGCS, the CIFS, EuroMALE and the SCAF will be developed. For the first three programs, German companies will be primary contractors, while the development of the SCAF will be headed by a French company. Which company will be chosen has yet to be decided. Germany's anti-corruption laws mean there has to be a bidding process, rather than the government dictating that KDNS will get the contract. The official press statements from the French and the German ministries of defence do not say that KDNS will be responsible for the MGCS, because they cannot make the decision yet. The press releases from KMW and Nexter pretty much say "we are cooperating, please choose us". As a matter of fact, Rheinmetall is also bidding to become the primary contractor for the MGCS. The rumor mill suggest that they are in a better position and might be prefered over KMW. Back when Krauss-Maffei was chosen for the Leopard 1 and Leopard 2 programs, it was the largest defence contractor with the capacity to manufacture MBTs in (West-)Germany. MaK, the second-largest, was chosen as a secondary contractor (making 45% of all tanks, while Krauss-Maffei made 55%). However in the past decades Rheinmetall has become a gigantic company that has swallowed roughly a dozen of smaller German & European defence vehicles and arms manufacturers (among them MaK, Thyssen-Henschel, Oerlikon, KuKa, Chempro, MAN military, etc.),: currently Rheinmetall has more than 23,000 employes, while KMW has just 2,700. The larger company also invests more into research and development (even without an official government requirement), while KMW over the past years has been satisfied with only becoming active once a requirement has been published. Finally there is a difference in structure: Rheinmetall is easier to work with, as it is not a family-owned company (like KMW). Only the future will show wether KMW's move to join sides with Nexter to form KDNS was a way to win the MGCS contract or not. Rheinmetall has announced that they will show "something" in regards to the MGCS in December of this year. Probably just some 3D models or testbed, because the exact concept of the MGCS has yet to be revealed by the governments. Rheinmetall is already working on its own idea of a next-generation tank (might become independent of the the MGCS) in their own secret facilities. Interesting note is that Ben Hudson from Rheinmetall asked "How do you defeat a tank that has four active defense systems on it?"... General Dynamics will apparently not bid for the MGCS, as they think their ASCOD 2 might be enough for the tank market of the future. https://www.defensenews.com/digital-show-dailies/eurosatory/2018/06/25/tank-makers-steel-themselves-for-europes-next-big-land-weapon-contest/ https://www.defensenews.com/digital-show-dailies/eurosatory/2018/06/14/when-does-industry-expect-france-and-germany-to-set-its-future-tank-requirements/

    What? No, that's a ridiculous oversimplification. Real power structures are filled with ambiguity, intrigue, and realities that don't line up with paper org structures. So, sure, on paper the President is in charge of the Executive Branch and therefore everyone in the US Department of State should click their heels and do exactly what he says all the time because that's what the org chart says. Meanwhile, in the real world, it hasn't worked that way since 1883. Or maybe even 1867. Ask yourself this; if the President has absolute power over all Executive departments, then why hasn't Trump fired absolutely everyone and replaced them all with his toadies? The US government did work that way at one point. It was a terrible way for the government to work because every election cycle that a new party took power, every government employee was replaced with some toady of the new president. So the Republican Party changed it in 1883 to make the vast majority of Executive departmental workers untouchable by politicians with the conspicuous exception of the cabinet-level heads of the departments, who are a vestigial remnant of the old spoils system.
