    Artillery, helicopters, MLRS. Looks like WW2, at some moments.

    Kind of.
     





     
    ^last one is more of military defense than civil defense though. It's a small military base.
     
    Had more of these on my PC, but can't access it atm.

    An SU-34 in Syria being re-fueled and re-armed.  Note the deflected canard.
     
    The SU-34, being a medium bomber rather than a fighter, does not need the canards so much for extreme maneuvering.  However, they are still useful.  Because the canards sit in front of the main wing, they normally move the center of lift forwards, destabilizing the aircraft.  The SU-34 is expected to carry heavy and variable loads of weapons and fuel, which also affect its stability.  By "feathering" the canards, that is, allowing them to move freely and align themselves with the direction of the air, the center of lift can be shifted rearwards to compensate for any destabilizing effect caused by the fuel or weapons load.  When the weapons are released, the canards can be "turned on" again, pulling the center of lift forward again.  In this way, trim drag can be minimized and aerodynamic efficiency maintained throughout the mission, even as the load is shifted around.
     
    The MiG YE-8 prototype used this trick, although in a more limited way:
     

     
    At subsonic speeds the canards were "feathered," and free-floated so that they did not contribute to lift.  At supersonic speeds they were locked in place to shift the center of lift forward, to compensate for the rearward shift in the center of lift that occurs over the main wings at supersonic speeds.

    I was there during this.  Part of MND-N Tuzla.  First time I ever worked with Russian soldiers (who got a kick of me understanding Russian.)

    The only way to save America from ISIS to to have a base on Mars to launch freedom lasers at super velocities and to save Aliens from Islam before you get suicide UFOs.

    I think he means that they are not doing very much if any space exploration (sending probes, etc) since the fall of the USSR.

    Fake, second part of this video is edited game footage, either from Lock On or another similar type of games (simulator). AFAIK Su-25s don't fly so low during day operations. I never actually saw Su-25 used during dayligh. They were used at night airstrikes, but thats all.

    Mohamed A reacted to Walter_Sobchak in The Preliminary T-72ology Thread   
    That picture came out of an US Armor school book on Main Battle Tanks published in 1973.  As far as I can tell, that picture was one of the first the west got of early model T-64s, which they for some reason called T-70's.  The notion that there was a tank called the T-70 persisted for a while.  In fact, there is an amusing series of letters in ARMOR magazine between Steven Zaloga and a young Jim Warford arguing about it.  I have to run off to work, but when I get home I'll look it up.

    Unlikely, maybe one of those many signals flag. Or photoshoped to it

    As i understand, we have an agreement with Israel that we don't deal with Hezbollah, don't supply them or arm them. They are coordinating with Iran, i guess.

    This article had made the rounds earlier on the Sturgeon's House Teamspeak and elsewhere, and was roundly and soundly mocked.  Weaponsman had some fun with it as well.  The authors have, bless their hearts, stuck to their guns and kept the article up, albeit edited for "greater technical clarity."

    The mistake the authors are making; a mistake obvious to anyone with a high school understanding of physics, is that re-arranging subatomic particles is quite qualitatively different than re-arranging atoms and molecules.  The authors cite, with breathless anxiety, the fact that 3D printers are able to manipulate smaller and smaller chunks of matter.  Surely the ability to arbitrarily re-arrange matter is just around the corner!
     
    Back in the real world, we know that "atoms" are well-named.  While they are not exactly un-cuttable, as the Greek etymology of the word suggests, the forces that bind the nucleons of an atom together are several orders of magnitude greater than the forces that bind the electron shells of atoms together to make molecules and metals.  Any mucking around with the arrangement of the nuclei of atoms is going to either take or produce an enormous amount of energy.  This is what makes nuclear weapons so scary in the first place.
     
    So, any civilization that could casually re-arrange matter on the subatomic level would regard our fission weapons with approximately the same consternation as they would a sharpened flake of obsidian.  They would be capable of much scarier things than silly little toys like nukes.
     
    The writers go on, incoherently, to point out that 3D printing could conceivably be used with fissile materials.  This is technically true, I suppose, although fissile materials have somewhat tricky physical properties such as multiple phase changes, and pyrophoricity.  Also, bomb cores need to be manufactured to such extreme tolerances that it's unclear what 3D printing would gain you.  And all of this of course begs the question of where said fissile material would come from in the first place.  Which the article never answers.  Because its authors know nothing about nuclear physics.  Because they are poly sci majors, and poly sci doesn't teach you anything useful about anything.  Sorry poly sci majors; you just wasted years and untold kilobucks on a completely useless education.  Better luck next time, and don't burn yourself on the deep fryer racks; that smarts like a motherfucker.
     
    This isn't even getting into the fact that the 3D printing revolution is not just around the corner; it's already here.  Additive manufacturing techniques are already used in the manufacture of important things like turbine blades and aerospace fasteners.  Typically, hand-wringing about some great advance in technology that has social implications works better when the great advance is still in the future.  That way you can make wild and absurd predictions and they're basically unfalsifiable if you word them correctly.
     
    But that's enough making fun of the poor, dumb bastards who wrote this thoroughly idiotic article.  They're just victims of the education system.  Nobody seriously believes that the technology to manipulate smaller and smaller amounts of electrical bonded matter presages the ability to manipulate subatomic matter arbitrarily, right?

    Sadly, wrong.  There is an entire field of study devoted to misunderstanding the implications of micro-manufacture.  It's called nanotechnology.  The entire field is, so far as I can discern, either outlandish claims based on bad analogies, or mundane discussion of what is already routine.  Scott Locklin provides an excellent general fisking here, while specific problems with some of claims made by nanotechnology proponents are tackled at LessWrong here.
     
    The derp is everywhere.  Sometimes it will appear wearing the uniform of someone knowledgeable.  Trust... but verify.

    Today, the Federation Council approved the use of the Russian Air Force in Syria.

    It's also funny how the Soviets did almost everything related to the space race and yet the Americans get the credit because they landed on the moon.
     
    inb4 Russia secretly lands on Mars, surprising the evil capitalists.

    AFAIK it will primarily replace the left over Tu-95MS's, which itself makes it invaluable.

    Unfortunately, it is a symptom of the United States appropriations process. Even if you could work up the political capital to allocate eleventy jillion dollars in a decade long effort to colonize Mars, eight years from now there'll be some dipshit "Budget Hawk" on an appropriations committee who'll shut it down because 60 Minutes did a news show on how part of the program is overbudget.

    Wouldn't it be very salty due to the condition on Mars? And empty from nutrients.
