A pair of skydivers nearly had an unfortunate run-in with two US Air Force F-15 fighter jets in the skies above southern England earlier this year, a British air safety board reports.
The US fighters out of RAF Lakenheath, home to the US 48th Fighter Wing, were flying at 345 mph above Cambridgeshire on April 17, 2019. Above Chatteris airfield, a popular skydiving location the fighter pilots were not aware was active, two parachutists were in freefall at roughly 120 mph, Stars and Stripes reported, citing a UK Airprox Board report released this past summer.
The skydivers captured video footage of the fighters passing beneath them.
“The Board was shown Go-Pro footage filmed from the helmet of one of the parachutists and could clearly see the F15s passing beneath,” the report read, further explaining that “once the parachutists had seen the F15s there was very little they could do to avoid the situation, having no control over their speed or direction whilst in freefall.”

There was a debate about how close the fighters actually came to the skydivers, Airprox explained, adding that the board eventually concluded that “safety had been reduced much below the norm.” The pilots did not see the parachutists, nor were they aware of any planned jumps.
Chatteris airfield, according to the Airprox report, notifies Lakenheath every morning of its planned activities. The board agreed that “there was very little more that Chatteris could have done from an operational perspective to prevent” this near-miss, which was the result of problems both on the ground and in the air.
In response to this incident, the 48th Fighter Wing is briefing crews again and reminding everyone of the need to steer clear of the Chatteris skydiving site.

RAF Lakenheath is “using this incident to reinforce the vital importance of situational awareness and attention to detail for all of our air traffic controllers and aircrew,” Col. Will Marshall, commander of the 48th Fighter Wing, told Stars and Stripes.
“UK airspace is incredibly complex and often congested, and the safety of our aircrew as well as those we share the skies with is our number one priority,” he added. The Airprox report noted that prior to the near-miss with the skydivers, the F-15s had been forced to change course to avoid a KC-135 refueling tanker that was determined to be “on a collision course with the formation.”
It was apparently that course change, combined with various other influencing factors, that sent the fighters over Chatteris and put the skydivers in danger.

The Trump administration has hit China with tariffs on $250 billion in consumer and industrial goods in 2018, and now sanctions tied to Beijing’s arms deals with Russia are being added to the mix.
On Sept. 20, 2018, the State Department said it would impose sanctions on China’s Equipment Development Department and its director, Li Shangfu, for “significant transactions” with Russia’s main weapons exporter, Rosoboronexport.
The Equipment Development Department oversees procurement of China’s defense technology.
The Chinese entities will be added a sanctions list established under the Countering America’s Adversaries Through Sanctions Act, or CAATSA, which was passed in August 2017 and went into effect in January 2018.
The law is meant to punish Russia for actions that include meddling in the 2016 US presidential election. Countries trading with Russia’s defense and intelligence sectors — including US allies — can face secondary sanctions, though a waiver process was included in the legislation. (The US added 33 other people and entities to the list on Sept. 20, 2018.)
“Both transactions resulted from pre-Aug. 2, 2017, deals negotiated between EDD and Rosoboronexport,” the State Department said.
“Since China has now gone ahead and, in fact, done what is clearly a significant transaction … we feel it necessary and indeed we are required by the law [to] take this step today,” a senior administration official said.
This is the first time the US has sanctioned a buyer of Russian weapons under the law. While the sanctions were imposed on China, the State Department official said the move was directed at Moscow.
“The ultimate target of these sanctions is Russia. CAATSA sanctions in this context are not intended to undermine the defense capabilities of any particular country,” the official said. “They are instead aimed at imposing costs upon Russia in response to its malign activities.”
China and Russia have both lashed out at the sanctions.
Russia dismissed the measures as an “unfair” measure meant to undermine Russia’s position as a major arms exporter. (The US and Russia are the world’s two biggest weapons suppliers.)
Those subject to the sanctions are blocked from foreign-exchange transactions subject to US jurisdictions. Russian Foreign Minister Sergey Lavrov said Sept. 21, 2018, that Moscow was doing what it could to not depend on the international financial system over which the US has influence.
“We are doing all that is necessary not to depend on the countries that act in this way regarding their international partners,” Lavrov said, according to state-controlled media.
China also bristled at the sanctions. A Foreign Ministry spokesman said Beijing was “strongly outraged by this unreasonable action” and that China “strongly urged the US to immediately correct its mistakes and revoke the so-called sanctions. Otherwise it must take all consequences.”
India, a major US partner, similarly plans to buy the S-400, and it and other US partner countries are also major buyers of Russian weapons.
U.S. Secretary of State Michael R. Pompeo flanked by U.S. Secretary of Defense Jim Mattis, Indian Minister of External Affairs Sushma Swaraj and Indian Defense Minister Nirmala Sitharaman delivers closing remarks at the 2+2 Dialogue, in New Delhi, India, Sept. 6, 2018.
While the legislation was under discussion, US defense officials requested exceptions be made for those countries that worked with the US but still needed to buy Russian arms.
At the end of August 2018, the Pentagon’s top Asia official said the “impression that we are going to completely … insulate India from any fallout” related to the sanctions was “a bit misleading.”
But as of early September 2018, when Defense Secretary Jim Mattis and Secretary of State Mike Pompeo met their Indian counterparts in New Delhi, Pompeo said there had been no decision on action over India’s purchase of the S-400.
The sanctions will ban the Chinese company from export licenses and from foreign-exchange transactions that take place under US jurisdiction and block the firm from the US financial system and its property and interests in the US.
Li, the director, will be barred from the US financial system and financial transactions, have any property and interests blocked, and be barred from having a US visa.
“Today’s actions further demonstrate the Department of State’s continuing commitment to fully implement CAATSA section 231, which has already deterred billions of dollars-worth of potential arms exports from Russia,” the agency said.

Mindy N. asks: After a long run my leg muscles are tired, but my heart is not. Why doesn’t the heart need any rest?
An average of around 60 to 100 times every minute of every day of every year of your ultimately meaningless life, your heart beats… until it doesn’t. Not long after it stops, all knowledge of your having existed is rapidly forgotten. Unlike the other muscles in your body, however, your heart steadfastly rages against the dying of the light, refusing to ever get tired. But how does it manage this and why are your other muscles such slackers in comparison?
To begin with, the human body is broadly composed of three types of muscles: skeletal, smooth and cardiac. Skeletal muscles are striated (banded), and are what most of us think of when we envision a muscle — controlling pretty much all voluntary, and some involuntary, body movement.
Like cardiac muscle, skeletal muscle derives energy from ATP (Adenosine triphoweknowyoudontcare), with this being made in a few different ways. To avoid going full textbook, we’ll just briefly give the high level over simplified view here. In a nutshell, the slowest, but most efficient, method of ATP production is via aerobic respiration where mitochondria in your muscle cells draw energy from the Dark Dimension, producing ATP, a small amount of which is stored in your muscles at any given time. This stored amount is a sufficient supply to last for about 3 seconds of vigorous activity, not unlike your high school boyfriend.
Diagram of the human heart.
After this supply is taxed, with the ATP converted to ADP (adenosine diphosophate) in the process, creatine phosphate in the muscles is used to convert it back to ATP. This supply will last about 8-15 seconds.
Next up, it turns out we were totally wrong about that whole Dark Dimension thing as, in fact, your muscles continue to get ATP beyond this via a series of chemical reactions resulting in glucose being used to make the needed ATP to keep going. This glucose comes from a variety of sources, such as glycogen in your muscles, or via blood via fats, protein, stores in the liver, and from your food churning away in your intestines.
There are two high level ways this production of ATP ends up being accomplished. In the first, using large supplies of oxygen. In this case, as much as 38 ATP molecules can be produced for every glucose molecule. In the second case, via anaerobic glycolysis — not requiring oxygen — only 2 molecules of ATP are produced for each molecule of glucose. While an extremely inefficient use of the available supply of glucose, this method at least produces the ATP over two times faster than aerobic respiration and continues working for a time while you’re out of breath.
Due to glycolysis resulting in the accumulation of lactic acid in the muscles, ultimately if it accumulates faster than it can be gotten rid of, it will interfere with the anaerobic glycolysis process and your muscles are going to go all jelly and cease to work as well for a little bit. This is in part why, if you get out of breath when exercising and your body is relying more on anaerobic glycolysis, you get fatigued extremely quickly. In this case, you’re simultaneously creating lactic acid at a much more rapid rate and using up your available glucose molecules faster, but producing relatively small amounts of ATP for those molecules used. Do this for more than a minute or two and it will overtax your skeletal muscles’ ability to produce the needed ATP at the rate you’re using it. (Though, again, your mileage will vary based on your current fitness level.)
Back it off and so you’re relying mostly on aerobic respiration and you’re going to get the most bang for your buck, able to keep going all night long if you keep hydrated and well fed. Slow and steady wins the race.
Unsurprisingly from all of this, the more mitochondria there are, the faster ATP can potentially be produced if the needed molecules are present and the more the muscle can keep on keeping on. As for skeletal muscle, about 2%-8% of the volume of such muscle is mitochondria, though this varies somewhat from person to person depending on your level of physical fitness.
Moving on to smooth muscle, as you may have gleaned from the name, this is smooth with no striations. Found in your hollow internal organs (except the heart), smooth muscles work automatically, helping you digest food, dilate your pupils and take a wee-wee. As an example of smooth muscle in action, in digestion, the contractions themselves are really not too dissimilar to how your heart beat works — fluctuation of electrical potential in the smooth muscle cells which causes the muscle to contract in a rhythmic fashion, in this case called the “Basic Electrical Rhythm” or BER. This rhythm is about three times per minute in the stomach, and 12 times per minute in the small intestines. The sound you are hearing when your stomach and intestines make noise is the result of these muscular contractions mixing and moving chyme (the cocktail of digestive juices, food, microbes, etc.) and air along down the tube between your mouth and your waste disposal port.
As for the mitochondrial needs of these muscles, they are typically approximately that of your skeletal muscles, with mitochondria making up about 3-5% of the smooth muscle volume.
This finally brings us to the real hero of your life story — cardiac muscle. Like skeletal muscle, cardiac muscle is striated and like the other muscle in your body is primarily powered by mitochondria. The cardiac muscles, however, have as much as 10 times the density of mitochondria as your other muscles, at about 35% of the volume of your cardiac muscle.
It should also be noted that individual muscle cells in the heart actually do get regular rest thanks to how the heart beat actually works, which we’ll get into in the Bonus Fact in a bit. But the net result is that about 60%-70% of your life a given part of your heart is actually in a resting state.
Combining these micro-rests with the extreme amount of mitochondria and a large amount of oxygen from the heart’s awesome blood supply, this allows your heart all the ATP it needs to not get tired, assuming you’re not in an extreme state of starvation or doing some extreme form of exercise for extended periods well beyond your normal fitness regime.
On that note, the downside to needing so much ATP thanks to no extended downtime is that the heart really needs to rely on aerobic respiration to make sure it doesn’t run out of ATP, and thus it doesn’t take oxygen being cut off for too long from it before you’re going to have a bad time, unlike other muscles you can just stop using to help recover the needed ATP over time.
And, yes, it turns out the human heart can actually get tired and suffer damage if you’re trying to do some extreme form of physical activity outside your norm for lengthy periods, especially if in a low oxygen environment like at high altitude. In these cases, even the healthiest hearts can suffer damage, though given the other effects on your body of such extreme physical activity, typically most people will stop doing whatever before the heart is negatively impacted in a damaging way. In essence, your legs will give out before your heart does (usually), at least when talking energy supply. But that doesn’t mean in certain cases a measurable level of tiredness in the heart can’t be observed.
For example, in 2001, cardiologists studied a few dozen endurance athletes competing in a 400 km race in Scotland, which comprised of all manner of physical activities from paddling, rope climbing, running, biking, climbing, etc. and the whole event taking almost 100 hours. During this span, the athletes typically only slept about 1 hour per 24 hours during the event and otherwise soldiered on.
The results? At the end of the race, the athletes’ hearts were only pumping about 90% of the volume per beat they’d been managing before the race started.
That said, further research on endurance athletes calls into question the notion of “no permanent damage” being done. For example, researchers involved in a 2011 British study looking at British Olympians who competed in distance running and rowing (and specifically competing in at minimum a hundred events), found that as they aged they showed marked signs of heart muscle scarring, something that can lead to irregular heart function and, potentially, heart failure.
Of course, these are extreme examples, and for most people not doing ultra marathons regularly or competing professionally or semi-professionally in endurance events, this is unlikely to be a problem and the holistic health benefits of regular, vigorous exercise are likely to make up for it even then.
Ever wonder how the heart beat works? Well, wonder no more. In a nutshell, the heart is a four chambered pump. The top two chambers are called Atria, the bottom two are called Ventricles. They are separated from top to bottom by valves; the right and left sides are separated by a septum. So what makes the pump squeeze? When the hearts muscle gets “shocked”, it will contract and force the blood down its path, with the valves not allowing blood to flow back through the system, unless they are defective.
The blood’s path through the heart starts in a vein called the Superior Vena Cava. Then it enters the right atrium, flows through the tricuspid valve into the right ventricle. From there it travels through the pulmonic valve into pulmonary arteries, then the lungs. Now back to the heart and into the left atrium, through the mitral valve. The blood is now in the “strongest” chamber of the heart, the left ventricle. From there it gets pumped through the aortic valve and into the aorta and out to the rest of the body!
So what causes that infamous electric shock the heart receives approximately 60-100 times a minute? Short answer: Dormammu. Long answer: The exchange of electrolytes across specialized cells within the heart build up a differing electrical potential on either side of the cell. When this electrical potential reaches a certain level, it discharges and sends a shock down another unique set of cells within the heart, causing a shock and thus the contraction.
The specific set of cells that regulates the heart rate (in most people) are called the Sinoatrial node or SA node for short. The SA node (pacemaker of the heart) sits in the upper portion of the R atria near the entrance of the superior vena cava.
When the SA node sends out and electrical shock, it immediately shocks the atria. The pulse then gets “held up” in another set of cells called the Atrioventricular node, or AV node for short. This then transmits the impulse down to the bundle of His and then to two pathways called the right and left bundle branches. Then it’s transmitted to the rest of the Ventricles through what are called Purkinje fibers. All together this “shock” causes the atria to contract, then the ventricles. You’re still alive! (For now.)
So what and how do these electrolytes cause this shock? In an attempt not to give a physiology lecture of ungodly proportion, we will simply say that the main two electrolytes involved are sodium and potassium. Potassium normally sits inside the cell, and sodium outside. Potassium slowly leaks outside of the cell and sodium then goes inside the cell. This creates the differing electrical potential that builds up until the point of discharge. Other electrolytes also help in creating this differential, and they are calcium and magnesium. All together the harmony created by this yin and yang system of electrical and mechanical systems come together to make that wonderfully thumping thing inside your chest!

North Korea has reportedly started dismantling rocket launching and testing facilities that President Donald Trump has said it agreed to in an off-the-books deal, and it’s a major US victory in what have been fraught, slow-moving talks.
Following the Singapore summit between Trump and North Korean leader Kim Jong Un, the two sides released a joint statement that contained weak and vague language around denuclearization, much to the dismay of North Korea watchers hoping for concrete action.
More than a month since the summit, the US has kept its end of the agreement, but only on July 23, 2018, did the West get any indication that North Korea was holding its end.
Satellite imagery reviewed by 38 North, a website that covers North Korea, suggests North Korea is dismantling key parts of the Sohae Satellite Launching Station, where Kim has presided over the launch of rockets meant to put satellites in orbit.
So far, a rail-based site for transporting the rockets and a vertical engine testing stand have been dismantled, 38 North reports.
In absolute terms, this represents only a tiny fraction of North Korea’s nuclear infrastructure. But the action there has key components that may give cause for hope.

These sites are vital
North Korea, in past negotiations with the US, has proved extremely lawyerly and adept at finding loopholes in its agreements.
In 2012, when Kim had just taken power, the US under President Barack Obama negotiated a freeze on North Korean missile testing. Later, North Korea announced it would instead launch a rocket intended to carry a satellite into orbit.
Satellite launch vehicles are not missiles. They deliver a satellite into orbit, rather than an explosive payload to a target.
But both satellite launch vehicles and long-range missiles use rocket engines to propel themselves into space, meaning that working on one is much the same as working on the other.
The US, troubled by this obvious betrayal of the spirit of the agreement, then exited the deal.
By removing the rail infrastructure to set up satellite vehicle launches, North Korea may have signaled it won’t look to exploit the same loopholes that have wrecked past deals.
At Sohae, where cranes have been spotted tearing down an engine testing stand, the North Koreans have previously worked to develop engines for their intercontinental ballistic missiles.
A former U.S. Army’s Special Forces officer has been arrested in Alexandria, VA, and charged with passing secrets of American military units and personnel to the Russian military intelligence arm (GRU) for over a decade.
Peter Rafael Dzibinski Debbins, 45, was recruited by Russian intelligence operatives as he considered himself a “son of Russia,” according to a 17-page indictment that was released after his arrest.
John C. Demers, Assistant Attorney General for National Security said that,
“Debbins violated his oath as a U.S. Army officer, betrayed the Special Forces and endangered our country’s national security by revealing classified information to Russian intelligence officers, providing details of his unit, and identifying Special Forces team members for Russian intelligence to try to recruit as a spy [sic]. Our country put its highest trust in this defendant, and he took that trust and weaponized it against the United States.”
Debbins is the second person this week charged by the Justice Department for transmitting U.S. secrets to a foreign country. In the other case, a former CIA officer in Hawaii (Alexander Yuk Ching Ma) was arrested and charged with spying for China.
Debbins first agreed to spy for Russia back in 1996 when he was an ROTC cadet. His mother had been born in the former Soviet Union and Debbins told Russian GRU operatives who were trying to recruit him that he considered himself “a son of Russia.” He had told his Russian handlers that he considered the United States “too dominant” in world matters and that it “needed to be cut down to size.”
The GRU gave Debbins the code name “Ikar Lesnikov.”
In 1997 he married a Russian woman, the daughter of a Russian military officer from the Russian city of Chelyabinsk.
After graduating from the University of Minnesota and being assigned to a Chemical Co. in Korea, Debbins returned to Russia. He briefed his handlers on his unit, its mission, and personnel during a subsequent visit to Russia.
He offered to take a polygraph test for his handlers when they asked if he was working for an American intelligence agency. He told them that he wished to leave the military, but they encouraged him to stay. They further urged Debbins to apply for and join the Special Forces. He was told that “he was of no use to the Russian intelligence service as an infantry commander.” Debbins passed Special Forces Selection (SFAS) and the qualification course (SFQC) and was assigned as a captain in the 1st Battalion, 10th Special Forces Group (1-10 SFG).
On another trip to Russia, he briefed his GRU contacts about his SF unit, its personnel, locations, and mission. Debbins had his security clearance suspended and command of his A-Team revoked for an unspecified security violation in 2004 or 2005. He then left the military in 2005 with an honorable discharge, according to the indictment.
In subsequent meetings with his GRU handlers, Debbins disclosed information about his unit’s deployments to Azerbaijan and Georgia that were deemed “SECRET/NOFORN.” Debbins also gave the GRU the names of his former team members knowing that the Russians sought the “information for the purpose of evaluating whether to approach the team members to see if they would cooperate with the Russian intelligence service.” He also passed the names of two American counter-intelligence agents who tried to recruit him for an operation.
Once his active duty service was over he began to work for a Ukrainian steel company in Minnesota through his Russian contacts. He remained a member of the Reserves until 2010. During this time his security clearance was reinstated by an Army adjudicator, although he was warned that his family and business connections to Russia might make him “the target of a foreign intelligence service.”
Debbins was a “true believer” and not motivated by monetary gains. In fact, when the Russians (who are notoriously cheap in the intelligence world when it comes to paying agents) offered him id=”listicle-2647079043″,000 he initially declined it stating that he “loved and was committed to Russia.” He only reluctantly accepted the money as “gratitude for his assistance to the Russian intelligence service.” At a 2003 meeting, he was given a bottle of Cognac and a Russian military uniform.
The Justice Department did not divulge how it came to know that Debbins was spying for Russia. His last contact with his handlers was in 2011 when he told them that moved to the D.C. area (Gainesville, VA).
He will be indicted formally on Monday. He faces life imprisonment if convicted.
“The facts alleged in this case are a shocking betrayal by a former Army officer of his fellow soldiers and his country,” Alan E. Kohler Jr., FBI Assistant Director of the Counterintelligence Division, said in a statement.
If you’ve seen Full Metal Jacket, then you likely agree that Gunny Hartman was the breakout character of the film. That over-the-top, engrossing performance launched the career of R. Lee Ermey — even though his character met an arguably-deserved end.
But how do they really train the non-commissioned officers responsible for breaking in fresh recruits?

Believe it or not, in some ways, it’s a lot like boot camp. Both the Army and Marine Corps schools for those who instruct recruits (drill sergeants for the Army, drill instructors for the Marines – we’ll refer to both as “DI” for the purposes of this article) are designed this way on purpose: The DI needs to be an expert on basic training, so they must experience it for themselves.

But are they all really like Gunny Hartman? No. Let’s face it, some of what Gunny Hartman did to Pvt. Pyle (as played by Vincent D’Onofrio) would have landed him in some serious trouble. Furthermore, his overly aggressive technique simply isn’t always the best method.
“You can’t yell at everyone. You have to use, as my [non-commissioned officers] used to tell me, your tool box and you need to use those different tools. You can’t always yell at someone to get them to do what [they need to do,]” Army Drill Sergeant Dashawne Browne explains.
It’s not easy to become a DI. The Marines take in roughly 240 prospective DIs in a given year, and as many as twenty percent drop out. That might sound low for such an important position, but neither the Army nor the Marines take just anyone who applies. The Army seeks “the most qualified NCOs” who are willing to take on the responsibility of teaching recruits “the proper way to do absolutely everything in the Army, from making a bed, to wearing a uniform, to firing a rifle.”
There comes a time in every Marine’s life when they must join the varsity team known as The Fleet. The first few weeks are an exciting time of formations, picking up cigarette buds, and hazing training. The fleet is a Machiavellian jungle of NJPs, promotions, and broken promises that will make you want to deploy at a moment’s notice.
A healthy dose of pessimism is key to survival in your first unit because you’re not in a movie; this is a war machine, and you’re an essential cog. You’re where the metal meets the meat. Keep that motivation, though, you’re going to need it.
Here’s what you should not do when you arrive at your first infantry unit.
The easiest way to annoy everyone around you is to make jokes using a drill instructor’s voice. Do not assume that it will inspire some sense of brotherhood because all Marines go to boot camp. Wrong. Everyone has their own stories, and they will let you know how much easier you had it. The more experienced Marines have been in some serious combat, and, by comparison, you’re just a baby.
No one likes a B.O.O.T. (barely out of training) Marine, and you’re just going to have to accept that. It’s part of the culture; it’s part of maturing into a warfighter, it’s what you signed up for. When you’re alone with your peers, it’s fine to talk about what you went through, but knowing your audience will save you an untold amount of stress in an already stressful work environment.
Marines are proud — it’s on the recruitment poster — that doesn’t mean you should exclusively buy Eagle, Globe, and Anchor t-shirts. Diversify your wardrobe because it’s one of the few things that will allow you to hold onto what some psychologists describe as a “personality.”
Everyone around you can potentiality be in combat with you, and it’s a lot easier to risk life and limb for someone you like. If the man to your left or your right is doing something wrong, fix them, but do not ever snitch. You will be ostracized, given the worst assignments, and when they’re done with your disloyal carcass, you’ll be pushing papers at headquarters. HQ will also know that you’re a stool pigeon and will continue to treat you accordingly. The stigma has been known to last for years, Marine. One of the Infantry’s cardinal rules is to re-calibrate a misguided Marine’s moral compass through intense physical training but do not ruin their career.
It’s called taking care of your own.
It’s free real estate
Do not get in trouble before your first deployment
Keep your nose just as clean as your inspection uniforms. Every three years, an enlisted Marine will receive a Good Conduct Medal to add to their stack. While it is not necessarily easy to obtain due to barracks parties or dares gone wrong, it is not so taxing that it’s insurmountable. Getting in trouble will hold you back from promotions in a highly competitive MOS. If you don’t want to call that window-licking-moron that came with you from the school of infantry corporal, do not get drunk and embarrass yourself.
The Marine Corps Institute is a self-learning platform that adds points to the Marine promotion system known as a cutting score. It offers courses that teach about combat procedures and tactical knowledge of weapon systems. Some are easier than others, and there’s no reason for a fresh Marine to not do them. It will set you apart from your peers in the eyes of the leadership, and it makes the platoon look better on paper.
Every quarter, battalion HQ evaluates the progress each line company is making towards promoting their Marines. A Marine working on his or her MCIs will be spared working parties by their seniors because it is in their best interest as well. Although junior Marines will not witness Staff NCOs and officers brag or trash talk about each other’s platoons, this is another point they can bring up in Command and Staff meetings stating that their platoon should have the honor of leading the assault in training and in combat.
Round, smooth and iridescent, pearls are among the world’s most exquisite jewels; now, these gems are inspiring a U.S. Army research project to improve military armor.
By mimicking the outer coating of pearls (nacre, or as it’s more commonly known, mother of pearl), researchers at University at Buffalo, funded by the Army Research Office (ARO), created a lightweight plastic that is 14 times stronger and eight times lighter (less dense) than steel and ideal for absorbing the impact of bullets and other projectiles.
ARO is an element of the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory.
The research findings are published in the journal ACS Applied Polymer Materials, and its earlier publication in J. Phys. Chem. Lett. (see related links below)
“The material is stiff, strong and tough,” said Dr. Shenqiang Ren, professor in the Department of Mechanical and Aerospace Engineering, a member of University at Buffalo’s RENEW Institute, and the paper’s lead author. “It could be applicable to vests, helmets and other types of body armor, as well as protective armor for ships, helicopters and other vehicles.”
Round, smooth and iridescent, pearls are among the world’s most exquisite jewels; now, these gems inspire U.S. Army researchers looking to improve military armor.
The bulk of the material is a souped-up version of polyethylene (the most common plastic) called ultrahigh molecular weight polyethylene, or UHMWPE, which is used to make products like artificial hips and guitar picks.
When designing the UHMWPE, the researchers studied mother of pearl, which mollusks create by arranging a form of calcium carbonate into a structure that resembles interlocking bricks. Like mother of pearl, the researchers designed the material to have an extremely tough outer shell with a more flexible inner backing that’s capable of deforming and absorbing projectiles.
“Professor Ren’s work designing UHMWPE to dramatically improve impact strength may lead to new generations of lightweight armor that provide both protection and mobility for soldiers,” said Dr. Evan Runnerstrom, program manager, materials design, ARO. “In contrast to steel or ceramic armor, UHMWPE could also be easier to cast or mold into complex shapes, providing versatile protection for soldiers, vehicles, and other Army assets.”

This is what’s known as soft armor, in which soft yet tightly woven materials create what is essentially a very strong net capable of stopping bullets. KEVLAR is a well-known example.
The material the research team developed also has high thermal conductivity. This ability to rapidly dissipate heat further helps it to absorb the energy of bullets and other projectiles.
The team further experimented with the UHMWPE by adding silica nanoparticles, finding that tiny bits of the chemical could enhance the material’s properties and potentially create stronger armor.
“This work demonstrates that the right materials design approaches have the potential to make big impacts for Army technologies,” Runnerstrom said.
After several decades of service, the US Army might finally replace their lineup of UH-60 Blackhawk and AH-64 Apache helicopters.
Unveiled at the Farnborough Air Show in England, Bell Helicopter — in conjunction withLockheed Martin — debuted their latest creation, the V-280 Valor.
Similar to the V-22 Osprey currently in service by the US Marine Corps and Air Force, the V-280 applies a tiltrotor mechanism to fly similar to normal helicopters and aircraft. However, the similarities seem to end there, as significant upgrades look to eclipse its predecessor’s capabilities.
Bell claims that the new V-280 will now be capable of flying at twice the speed and range of current helicopter platforms. Features of the helicopter include a 500-800 nautical miles range, aerial refueling, a crew of 4 and 14 troops, carrying capacity of 25% more cargo than a Blackhawk, and its signature 280 knots true airspeed (KTAS).
According to Aviation Week, the Valor will also have a forward-firing capability and a technologically advanced glass cockpit — like Lockheed Martin’s F-35.
In addition to its performance, the V-280 will be more affordable than the V-22: due to the nature of its straight wing design, the V-280 would not only take half the time to construct compared to the V-22’s swept wing, but also half as cheaper — costing about $20 million, similar to the UH-60.
Other nations, such as Australia, UK, and Canada, have also followed suit in expressing interest in the helicopter. So far, the construction of the helicopter is about 60% completed and is slated to take its inaugural flight on September 2017.
Heat, smoke, and that loud “wop-wop” sound make helicopters easy targets on the battlefield. For these reasons, helicopters make the unlikeliest candidates for stealth technology. But during the 1990s and early 2000s, Boeing-Sikorsky challenged that notion with the RAH-66 Comanche helicopter.
The Light Helicopter Experimental program is the brainchild of the U.S. Army. It charged Boeing-Sikorsky with developing armed reconnaissance and attack helicopters. The result incorporated stealth technologies that minimized radar and human detection. It used advanced sensors for reconnaissance intended to designate targets for the AH-64 Apache. The helicopter was also armed to the teeth with tucked away missiles and rockets to destroy armed vehicles. Two prototypes were built and tested but the project was ultimately canceled in 2004.
The rivalry between branches can best be described as a sibling rivalry. We’re always making fun of each other whenever we can, calling the Air Force the Chair Force, the Coast Guard a bunch of puddle pirates — the list goes on. One thing that branches can’t seem to figure out, though, is a good, slightly insulting nickname for Marines.
It seems like the other branches tried to find some kind of insult for Marines but, instead, we’ve turned those monikers into sources of pride. We like being called names like Jarhead. It’s kind of cool, really. You’re saying our hair regulations are so disciplined it’s stupid? Maybe it’s your attitude toward discipline that has us always on the delivery side of insults. Think about it.
But one thing that’s sorta caught on and is becoming popular is calling Marines, “Crayon-Eaters.”
Well, here’s why that nickname just won’t hold water:
Snipers know why there’s some truth there…

1. First off, it’s just kind of… weak
Maybe we’re just too dumb to understand the insult here but, quite frankly, it sucks. It’s lame.
If you were to call your friend a “Crayon-Eater” in any other situation, they’d just shrug and say, “okay,” with a condescending tone. It’s no better than a Kindergarten insult. You might as well say, “you poop your pants!” At least then there’s some truth for some Marines.
“You think crayon-eater is funny?!”

2. It’s ironic
The whole point of the joke is to say that Marines are stupid. Got it. But you know what’s stupid? The joke itself. It’s ironic how dumb the joke is. Instead of making Marines look dumb, you actually just display the inability to create a layered, intelligent insult. “Crayon-eater” is so bland and overplayed that it loses any impact it might have.
We’re not afraid to take shots at each other because it’s all part of the brotherhood.

3. Marines have better insults for each other
The things Marines say to one another on a daily basis are way worse — it’s stuff so bad that we can’t even mention it on this website. They’re things that would make your average civilian’s stomach turn and cause airmen everywhere to puke all over their computer desks.
The worst part is that the joke isn’t even close to being offensive. Of course, some of you may read this and say, “this guy is just offended,” and the answer is no — and that’s the problem. You think something as lame as “crayon-eater” is going to offend a member of a tribe whose trainees are taught to yell, “kill!” during training?
Didn’t think so.
They’re laughing at you, not with you.

If you want to keep using the joke, go right ahead. Just remember, when a Marine laughs in your face because your joke isn’t doing what you thought it would — we tried to warn you.
The Latest on the Syrian conflict (all times local to Beruit):
Russian President Vladimir Putin says the Islamic State group in eastern Syria has suffered a “complete defeat.”
Putin, speaking on a visit to Nizhny Novgorod, said Russian Defense Minister Sergei Shoigu reported to him earlier December 6th that operations against the IS on both the western and eastern banks of the Euphrates River had been successfully completed.
Putin said some isolated pockets of resistance could remain in the area.
The Russian military says it has provided air support to Kurdish forces and local tribes in the oil-rich province of Deir el-Zour in eastern Syria and helped coordinate their offensive against the IS.
Russia launched an air campaign in support of Syrian President Bashar Assad’s forces in 2015.
Syrian activists say airstrikes have killed at least 12 civilians in an eastern Syrian village held by the Islamic State group.
Deir Ezzor 24 says Tuesday’s attack targeted the village of al-Jarthi. The Britain-based Syrian Observatory for Human Rights says 21 civilians were killed, among them 9 children. It says Russia carried out the strikes, in support of U.S.-backed, Kurdish-led forces driving to capture IS territory on the Euphrates River.
The Arctic could become the location of the next phase of an arms race between the United States and Russia – and the Russians have taken an early lead.
According to a report by Reuters, Russian military assets, including Cold War-era bases in the Arctic, are being brought back into service as Vladimir Putin makes a play to control what could be massive reserves of oil. The Russian build-up reportedly includes effort to winterize modern weapons, like the Su-34 “Fullback” strike aircraft and the MiG-31 “Foxhound” interceptor.
According to Globalsecurity.org, the Su-34 is capable of carrying up to eight tons of weapons or a dozen air-to-air missiles, has a crew of two, and saw some combat action over Syria. The Fullback is slated to replace Su-24 Fencers currently serving with the Russian Air Force and Russian Naval Aviation. That site also notes that the MiG-31, an improved development of the MiG-25 Foxbat interceptor, also has a two-person crew, and is capable of firing the AA-9 “Amos” air-to-air missile, which has a range of just under 100 miles. The Foxhound has been upgraded with a new radar.
Also included in the buildup are new icebreakers – including three nuclear-powered icebreakers according to a 2014 World Nuclear News report. In 2015, Port News reported that construction had started on two conventionally-powered icebreakers, while the Barents Observer reported in 2014 that the LK-25 would be delayed by up to two years from a planned delivery date of 2015.
Port News reported in December 2016 that the vessel, now named Viktor Chernomyrdin, wouldn’t be completed until sometime in 2018.
The British news agency noted that the push comes even though a combination of economic sanctions and low oil prices have shelved Russian plans to explore for some of the massive oil and natural gas reserves in the Arctic.
