The Marine Corps is always training to become smarter, stronger, and more lethal than those who threaten to destroy our way of life. Marines are outside dogs who thrive on the hunt, however, when not forward deployed, they train the next generation to fight.
The fundamentals used to build up a puppy into a war-dog may seem asinine at first, but they are either proving a concept, developing a character trait, or conditioning muscle memory.
1. Break falls
A break fall is one, if not the first, thing you’ll learn in the Marine Corps Martial Arts Program. This exercise focuses on muscle memory: tucking the chin or looking up, not reaching out, and dispersing the energy from impact so you can get back on your feet unharmed and continue the fight.
Break falling can take years to perfect (good thing you signed that contract), but it will make you a better sparring partner and will come in handy for those “oh sh*t” moments, like getting in a fight or slipping on an icy sidewalk.
2. Grass Week
Not every Marine is an infantryman, but every Marine is a rifleman. Generally speaking, it’s probably a good idea to have all personnel achieve proficiency with the metal object they have to carry for months on end while deployed.
Grass Week is when Marines develop muscle memory of shooting positions while aiming at an object (usually a barrel) while coaches fix their posture.
Proper bone support is a fundamental of marksmanship that will help you attain that Expert Rifleman Badge (and bragging rights over your peers). Unfortunately for the Marine, this means staring at the same barrel from dawn to dusk for five days straight.
3. Fighting Holes
Offense and Defense, also known as O&D, is when Marines have to defend their position against an advancing enemy, conduct patrols, and other combat operations. This also means hours or days of digging with a tiny shovel.
There are set measurements for fighting holes, but their command may take certain liberties contingent on the environment, time, and resources. Dig, fill, relocate, repeat.
4. Speed Reloads
Speed and tactical reloads make you look and feel like the operator bad ass you imagined yourself to be when signing that contract. The concept is simple: Develop muscle memory to the point that you can reload your weapon in pitch black darkness or blind-folded.
It’s a perishable skill that must be continually honed in the infantry community and it’s a great way to look busy if your staff sergeant is on the prowl for a working party.
As we all know, one must walk before they can run, which translates to many magazines being dropped prematurely.
Right off North Carolina Highway 147 in Durham sits a relic of older railroad overpass regulations. The 78-year old bridge that runs along South Gregson Street has a clearance of only 11 feet 8 inches. It has become known across the internet as “The Can-Opener Bridge” because of the astounding number of overconfident truck drivers who think they can squeeze their vehicle under it. Recently, the bridge claimed its 130th victim: an Army LMTV.
Local truck drivers know to avoid the overpass, so nearly every vehicle that gets clipped is either a rental or from out-of-state. The costs of raising the railroad tracks would be astronomical and the city’s main sewer line runs underneath, meaning lowering the road is impossible.
Thankfully, to date, there have been no fatalities and only three minor injuries. The city of Durham is content to plaster the area with a ridiculous amount of warnings to drivers, including a traffic light and gigantic, flashing sign that triggers if a height sensor is tripped. But all of these cautions don’t deter idiots drivers who aren’t willing to take a short detour.
To be completely honest, I don’t think they even want to fix it because it’s too funny.
So, what’s a city to do that has a hilarious problem that only affects morons who obviously don’t know their vehicle and fail to acknowledge the many signals? Put up a 24/7 webcam and create an internet attraction, obviously!
The most recent addition to the bridge’s long list of victims is a U.S. Army LMTV from an undisclosed unit. Many sites have erroneously claimed that the truck was carrying some “top secret device that needed to be covered” when it hit the bridge. In actuality, it was just a regular ol’ weapon mount that’s kept covered as not to freak out civilians. The driver of the vehicle has also not been named, but the Private (or soon-to-be-Private) is definitely never going to live this one down.
The Army has been tossing around the idea of adding another uniform to their wardrobe for a while now. During last year’s Army-Navy game, Sergeant Major of the Army Dan Dailey wore an updated version of the classic, WWII-era “Pinks and Greens,” which had many people predicting the iconic uniform would be making a comeback. Well, now it’s official.
The Army announced the upcoming addition of new Army Greens on November 11th and with it comes a whole slew of information that soldiers need to know.
Say what you will about the garrison cap, but it does bring back a bit of style back to the uniform.
First and foremost, they’re not called “Pinks and Greens” like the old WWII-era uniforms. These are called, simply, “Army Greens.” It seems like someone finally got around to realizing that the beige-colored shirt and pants aren’t actually pink.
While the Dress Blues will still act as a soldier’s dress uniform and the OCPs will still be used in the field or deployment, the Greens will be worn during duty hours while the soldier is stationed in garrison stateside or outside the continental US, like in Germany or South Korea.
Get ready for uniform inspections on a near daily basis everyone…
The biggest concern that a lot of soldiers have about the new uniform change is the price — which is entirely understandable. The Army has said that the change in uniform is “cost-neutral” and won’t be coming out of tax payers’ pockets.
That being said, enlisted soldiers will need to buy them using their annual clothing allowance. Sgt. Maj. of the Army Dailey told the Army Times in September that they are doing everything in their power to keep the costs low. Even still, it’s going to cost a bit for the average Joe.
Since it’s a duty uniform, the average soldier will need at least three sets to make it through the week before doing laundry. It will also require that soldiers spend more time preparing their uniforms for the next day, setting their ribbon racks right, shining their shoes, and keeping everything ironed. This could also off-set “hip pocket training” from being more sporadic as leaders would be less willing to mess up perfectly good uniforms.
Take that as you will.
I speak for all Army veterans when I say “F*ck yes!” to that jacket.
Costs and effort aside, there are a lot of positives coming with this change.
First off, the slight variations in the uniform seem poised to revive a strong sense of pride in the Army. It hasn’t been officially mentioned yet, but it seems as though airborne and Rangers will still wear their berets instead of the garrison cap. Units authorized to wear jump boots will wear those in lieu of the brown leather oxfords. The Greens also allow for more choices for female soldiers, as they can choose between pants or a skirt and pumps or flats.
Also, the new Greens will supposedly feature an “Ike-style” bomber jacket that goes over the Greens — and that’s badass.
New soldiers will receive Greens in basic training by summer 2020 and it’ll be entirely mandatory, service-wide, by 2028.
As with most uniform changes, it’ll probably look better on the soldiers that take the initiative and start buying them as soon as they hit the PX in summer 2020.
The US cyber strategy needs some major improvements if the country hopes to defend itself against threats from China, Russia, and other adversaries, according to a report released this week by a bipartisan group of senators.
Among its 80+ recommendations are the creation of a “national cyber director” overseen by new congressional committees on cybersecurity, more personnel trained in cyber operations, and increased funding to ensure federal agencies like the Department of Homeland Security and Election Assistance Commission are equipped to carry out increasingly complicated missions.
“The U.S. government is currently not designed to act with the speed and agility necessary to defend the country in cyberspace,” concluded the report, the result of a year-long study by the Cyberspace Solarium Commission, a group created by Congress in 2018.
“We want this to be the 9/11 Commission Report without the 9/11,” Sen. Angus King, one of the commission’s co-chairs, told Cyberscoop, adding that the group is “trying to urge and foment change without a catastrophic event.”
To accomplish that goal, the commission suggested the US adopt a “layered cyber deterrence” strategy. Broadly, that involves encouraging allies to promote responsible behavior in cyberspace, shoring up vulnerabilities in private and public networks that enemies could exploit, and being able to retaliate against attackers.
“China, Russia, Iran, and North Korea all probed U.S. critical infrastructure with impunity,” the report said, while globally connected networks allowed criminals to commit cyber theft and extremist groups to raise funds and recruit followers.
“American restraint was met with unchecked predation,” the report said, advocating that the US take a more active role in deterring bad actors.
However, the report did not address some of the more controversial topics surrounding cybersecurity, like encryption — a frequent target of US Attorney General William Barr and others in law enforcement — and which offensive capabilities the US might be willing to give up to secure similar agreements from adversaries.
The Cyberspace Solarium Commission was modeled after President Dwight Eisenhower’s Project Solarium, which was formed in the 1950s to help the US devise a new foreign policy strategy around the Cold War, showing that the US is fundamentally rethinking how it’s approaching new digital battlegrounds as the nature of warfare evolves.
It took 104 years, but the Marine Corps Reserve has grown from just 35 personnel to more than 40,000. To celebrate the USMC Reserve’s August 28 birthday, here’s a look at Marine heritage and culture.
USMC-R History and Origins
The Marines’ reserve component dates back to the Civil War when military and civilian readers recognized a need for a Naval Reserve to augment the fleet during wartime.
Leading up to WWI, individual states tried to fill the need through state-controlled naval militias, but the lack of a centralized national force limited combat effectiveness.
In 1916, President Woodrow Wilson recognized the need for an operational Reserve Force, and on August 29, the USMC Reserve was born. The organization grew from just 35 Marines on April 01, 1916, to 6,467 by the time Germany surrendered in November 1918.
Reserve Marines fought on the sea and land in major battles during WWI, and as the Marine Corps began expanding its horizons during WWII, the Reserve component continued to grow. The USMC Women’s Reserve was activated in July 1942, and in 1943, the USMC WR swore in its first director, Maj. Ruth Cheney Streeter.
However, by 1947, it seems like the Marine Corps and the Reserve component were going to be disbanded. Fortunately, the Armed Forces Unification Act created the Department of Defense, which helped standardize pay for Marine Corps Reserve service members, along with creating a retirement pay program.
At the end of the military draft and the transition to an all-volunteer military in the 1970s, the USMC-R would grow to be almost 40,000 members strong.
Celebrating the USMC-R Birthday
This internal observance isn’t a widely known date or public holiday, but Reservists don’t mind. To honor and celebrate the history of the USMC Reserve on its birthday, you might consider flying the Marine Corps flag alongside the American flag this week.
Consult the Marine Corps Flag Manual to learn how to properly display a USMC-R service flag alongside the national colors. Fair warning, and in true USMC nature, this flag-flying manual is no less than 50 pages long, so be prepared for a long and thorough read.
TL;DR: The flag represents a living country and is considered a living thing. The right arm is the sword arm, and so the right is the place of honor, so the edge of the flag should be toward the staff. Flags should be displayed from sunrise to sunset. If a “patriotic effect is desired for specific occasions,” the flag can be displayed for a full 24 hours if properly illuminated during hours of darkness.
Famous USMC Reservists
Like the other branches of the military, being a part of the USMC-R can significantly impact civilian careers. For Reservists, being a Marine often means being able to also continue with life’s other passions. Take a look at the most famous Marine Reservists. You might not know they were Leathernecks, but we’re pretty sure you know their work!
After enlisting in the Reserves in 1980, Carey went on to serve a total of six years. The comedian says that he adopted his trademark crew cut and horn-rimmed glasses because of his time in service. During his time in the Reserves, Carey was always looking for new ways to make money. Someone in his unit suggested using his jokes. Of his big break in Hollywood, Carey has often remarked that he would still be serving if he hadn’t made it big.

Retired Lt. Col. Riggle served in the USMC Reserve as a PAO from 199-2013. He served in Kosovo, Liberia and Afghanistan. He joined the Marines after getting his pilot’s license with the intent of becoming a Naval Aviator but left flight school to pursue his comedy career. He has appeared on the Daily Show and had a running role on The Office.
Interested in joining the USMC Reserves?
The USMC-R is a critical component to being able to provide a balanced, ready force. There’s no telling that you’ll end up a famous comedian like Drew Caret or Rob Riggle, but chances are you’ll grow as a person and learn something in the process, too. Find out more here.
Days after the first-in-class aircraft carrier USS Gerald R. Ford sailed out of a “challenging” post-shakedown work period that was extended three months because of maintenance problems, the dry dock holding the second Ford-class carrier, the USS John F. Kennedy, was flooded, launching the carrier three months early.
The Kennedy’s builders and crew have gotten a boost from the Ford, according to the ship’s commanding officer, Capt. Todd Marzano.
“We are definitely benefiting from being the second aircraft carrier in the class,” Marzano told Business Insider last week. “We’re leveraging their lessons learned, which has helped not only from the construction side but from our sailor training.”

A graduate of Naval Fighter Weapons School, or Top Gun, Marzano has gone to sea aboard Kitty Hawk-, Nimitz-, and Ford-class carriers, serving as a fighter squadron commander as well as executive officer and commanding officer of the carrier itself.
At a ceremony in May, Marzano recalled driving past the Ford as construction began in late 2015 and thinking that “some lucky captain” would get to be its first skipper. In a mast-stepping ceremony after that speech, he put his first set of gold aviator’s wings under the 650-ton island as it was lowered onto the flight deck.
That “signified my commitment as the CO of the ship to ensure … that I’m going make sure that the crew is ready to do their job and operate the ship when we take it out to sea,” Marzano said. “So it meant a lot to me. This is definitely a pinnacle tour in my career.”

Marzano assumed command of the Kennedy, designated CVN-79, on October 1, at a ceremony attended by the carrier’s first 43 sailors, who were handpicked for the assignment.
“We officially stood up the command on October 1, and as of today we have just over 150 crew members on board, and that number just continues to grow daily,” Marzano said on Nov. 19, 2019. “The current focus since they’ve shown up is to create a solid foundation, which means getting our programs, our procedures established. We’re also focusing on a lot of training and, most importantly, developing a healthy culture throughout all levels of the command.”
Marzano added that “some of the sailors on the Ford have now been transferred over to our ship, so we can benefit from their knowledge … gained on their tour.”
The Ford-class carriers — the Ford, the Kennedy, the Enterprise, and the unnamed CVN-81 — are or will be equipped with new technology the Navy believes will keep them effective for decades to come. The Ford’s first sailors, with months or even years of hands-on experience with that tech, were creating “basically instructions on how to operate this ship with its systems and its new design,” as one sailor put it.
“Now we’re going to benefit from that, and they can help train our new sailors,” Marzano said.
The island of the Kennedy is placed on the flight deck during a mast-stepping ceremony in Newport News, Virginia, on May 29, 2019.
In addition to changing or excluding some features, the Navy and the carrier’s builder, Huntington Ingalls Industries, have made changes to the Kennedy’s build strategy to control costs and stay on schedule.
The Ford was being built as it was being designed, according to Mike Butler, Huntington Ingalls’ program manager for the Kennedy. But the Kennedy had a complete model, saving time.
“Every piece of pipe, every cable, every other piece of equipment was loaded in a three-dimensional product model, and that gave us the ability, for example, [to do] hole cuts, where you have a bulkhead or a deck and you have to cut a hole in it for a pipe to go through or an electrical cable,” Butler told Business Insider on Nov. 29, 2019.
On Nimitz-class carriers, “prior to the product model,” Butler said, “we probably cut 75% of those holes on ship once we ran the pipe and saw where it went through the bulkhead.”
There was “much less” cutting on ship on the Ford because of the product model, Butler said. But on the Kennedy, “with the complete product model, I virtually cut 100% of all of those hole cuts in the ship.”
“While the shop was still fabricating the deck plates and bulkhead panels, they could go in and robotically locate and cut all of those holes in those structural members while it was still in the shop environment, which is a big deal because there are probably close to 100,000 holes that go through decks and bulkheads that have to be cut,” Butler added.
The upper bow unit of the Kennedy is fitted to the primary structure of the ship on July 10, 2019.
The design and planning documents for the Kennedy were updated as work continued on the Ford. But the biggest change was in how the second Ford-class carrier was actually put together, Butler said.
About 1,100 structural boxes are built to assemble the carrier, each outfitted with components like wiring. Those boxes are put together into larger sections called super lifts, which are outfitted further. The carrier is then assembled from those super lifts — “sort of like a Lego build,” Butler said.
On the Kennedy, “particularly early in the program, we did a lot more outfitting,” Butler said. “We built larger boxes in our steel fabrication division. We brought those to our final assembly plant. We built larger super lifts than we did on [the Ford] in some areas, and we put more outfitting in a lot of those super lifts, particularly early in the program.
“So we ended up with less lifts into the dock and many cases of larger super lifts that had more outfitting … which drives your cost down as well,” Butler added.
“We’re definitely aggressively seeking the lessons learned and then applying them to the Kennedy, and we’re already seeing benefits of that. Construction progress has gone much more efficiently,” Marzano said. “So both on the construction and the level-of-knowledge side for the sailors, that’s paying off. Being the second in class is definitely easier in that regard for sure.”

The Ford’s marquee features have been among the most troublesome, particularly the advanced weapons elevators, drawing congressional scrutiny and the ire of former Navy Secretary Richard Spencer, who excoriated Huntington Ingalls, saying last month that the shipbuilder had “no idea” what it was doing.
Those electromagnetically powered elevators are supposed to carry more ordnance faster — up to 24,000 pounds at 150 feet a minute over Nimitz-class elevators’ 10,500 pounds at 100 feet a minute — from storage magazines deep in the hull. But just four of the Ford’s 11 elevators have been certified and turned over to the crew.
Those new elevators have new electrical and mechanical technology and are “a lot more complex than traditional weapons elevators,” with “a lot tighter tolerances because of that,” Butler said.
Work on the Kennedy’s elevators was delayed to incorporate lessons from the Ford, Butler added.
“A lot of the areas where they’ve had issues that they’ve had to resolve we’ve been able to hold back, get those issues resolved, change the design, change the work documents,” Butler said. “That allows us now to go in and do that work the first time with those lessons learned already.”
Sailors review safety procedures for the Upper Stage 1 advanced weapons elevator in the Ford’s weapons department on Jan. 16, 2019.
Those pauses didn’t affect work on the hull and parts of the ship exposed to seawater, allowing it to be launched ahead of schedule in October 2019, Butler said.
In addition to being ahead of schedule, the Kennedy was also 5% more complete than the Ford at the time of its launch, according to James Geurts, the Navy’s acquisitions chief.
Like Marzano’s crew, Butler’s team has also benefitted from an influx of personnel from the Ford.
Butler said that “working through all those different technical issues” on the Ford, they had “developed a set of industry experts at the shipyard, and our design, manufacturing, construction, and testing of those elevators.”
“Now that expert team is beginning to migrate to my ship, bringing those people and those lessons learned, working with my team,” Butler added, “so that we’ve got people on the deck plate who’ve been through these elevators, helping us modify our build plan to improve that process.”
Butler declined to comment on Spencer’s criticisms, saying he was “laser-focused” the Kennedy.
“Morale is great. We know we’ve worked through a lot of the first-in-class problems,” Butler added. “We are building this ship cheaper; we’re building the ship faster. And to us that is showing that first-of-class-to-second-of-class improvement is exactly what we thought it would be.”

Sometime after August 2008, the US Department of Defense contracted dozens of researchers to look into some very, very out-there aerospace technologies, including never-before-seen methods of propulsion, lift, and stealth.
Two researchers came back with a 34-page report for the “propulsion” category titled, “Warp Drive, Dark Energy and the Manipulation of Extra Dimensions”.
The document is dated April 2, 2010, though it was only recently released by the Defense Intelligence Agency. (Business Insider first learned about in a post by Paul Szoldra at Task & Purpose.) The authors suggest we may not be too far away from cracking the mysteries of higher, unseen dimensions and negative or “dark energy” — a repulsive force that physicists believe is pushing the universe apart at ever-faster speeds.
“Control of this higher dimensional space may bе а source of technological control оvеr the dark energy density and could ultimately play а role in the development of exotic propulsion technologies; specifically, а warp drive,” the authors write. “[T]rips to the planets within our own solar system would take hours rather than years, and journeys to local star system would be measured in weeks rather than hundreds of thousands of years.”
However, Sean Carroll, a theoretical physicist at Caltech who studies and follows the topics covered by the report, had a lot of cold water to pour on the report’s optimism.
“It’s bits and pieces of theoretical physics dressed up as if it has something to do with potentially real-world applications, which it doesn’t.” Carroll said. “This is not crackpot. This is not the Maharishi saying we’re going to use spirit energy to fly off the ground — this is real physics. But this is not something that’s going to connect with engineering anytime soon, probably anytime ever.”
James Т. Lacatski, a Defense Intelligence Agency official listed as a contact on the report, did not immediately to respond a query from Business Insider.
Where the warp-drive study came from
The nature of this study is still making its way to the public.
What is known is that it’s an “acquisition threat support” reference document, which helps the US military anticipate or describe new enemy technologies — apparently including (very, very) notional ones. It was also one work in “а series of advanced technology reports” for something called the Advanced Aerospace Weapon System Applications Program, or AAWSAP.
The New York Times and Politico revealed AATIP’s existence in December 2017. The outlets said former Nevada senator Harry Reid helped organize it and secure millions in secret government funding (sometimes called “black money”) for the effort.
A large share of this money reportedly went to Robert Bigelow — a real-estate mogul who’s working to build private space stations through Bigelow Aerospace, is a friend of Reid’s, and someone who has funded his own UFO research for years. The billionaire reportedly formed a separate entity, called Bigelow Aerospace Advanced Space Studies, to secure the government funding and use it to hire 46 researchers and “dozens of other support personnel,” KLAS-TV said.
An anonymous senior intelligence official told Politico that AATIP began mostly to root out the existence of unknown Chinese and Russian military technologies. But after a couple of years, “the consensus was we really couldn’t find anything of substance,” the official said. “They produced reams of paperwork. After all of that there was really nothing there that we could find.” AAWSAP and AATIP reportedly ran out of funding in 2011 or 2012.
Scientists are also skeptical of UFOs, even after viewing spooky videos obtained by AATIP, one of which shows an undated encounter with “an aircraft surrounded by some kind of glowing aura traveling at high speed and rotating as it moves,” the Times wrote.
Seth Shostak, a senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute previously told Business Insider that, after 50 years of reported alien visits, “the really good evidence that we’re being visited still has failed to surface.” He added: “It is a little odd that aliens would come hundreds and hundreds of light-years to do nothing.”
The larger program that looked into the feasibility of warp drives, wormholes, and stargates is meeting similar scrutiny from established experts.
The physics of warp drives
In the warp-drive study, the authors laid out several well-established ideas in physics.
Those concepts include dark energy; general relativity, which Albert Einstein pioneered and predicted some bizarre-yet-real phenomena in the universe (like the warping of spacetime and gravitational waves); the Casimir effect, which describes the existence of a quantum “vacuum energy”; and M-theory — the idea that perhaps seven extra dimensions (which a warp drive could exploit) may be wrapped up in the four we’re familiar with, including time.
It then mashes this work together to lay out a potential use of these properties that’d circumvent Einstein’s cardinal rule: Nothing can travel faster than light in a vacuum.
“If one is to realistically entertain the notion of interstellar exploration in timeframes of а human lifespan, а dramatic shift in the traditional approach to spacecraft propulsion is necessary,” said the report, which goes on to suggest that a warp drive might be feasible.
The study includes a table of various destinations and how quickly they might be reached by bending spacetime to travel 100 times faster than light.
The way this might work, the report says, is by using a lot of dark (or negative) energy to expand an extra dimension into a “bubble.” Such a bubble would be made large enough to fit a spaceship of perhaps 100 cubic meters — roughly the size of a semi-trailer truck.
A contracting region of spacetime in front of the ship, plus an expanding region behind it, would then propel the bubble and ship down a sort of spacetime tube without technically exceeding the speed of light.
Carroll also said that the concept of a warp drive “is not crackpot” — Miguel Alcubierre, a Mexican theoretical physicist, invented the concept in 1994.
“You can’t go faster than the speed of light. But what you can can imagine doing is effectively twisting spacetime so that it looks like you’re moving faster than the speed of light,” Carroll said. “If you want to go to Alpha Centauri, for example, you can ask yourself, ‘Well, could I bend spacetime so that Alpha Centauri is next to me, so that it takes a day to go there, rather than tens of [thousands of] years? Can I make the warping of spacetime do that?’ And the answer is sure, you can do that.”
But Carroll said the DIA report goes too far in its analysis.
“There is something called a warp drive, there are extra dimensions, there is a Casimir effect, and there’s dark energy. All of these things are true,” he said. “But there’s zero chance that anyone within our lifetimes, or the next 1,000 years, are going to build anything that makes use of any of these ideas, for defense purposes or anything like that.”
The problems and perils of faster-than-light travel
Carrol said warp drives are so removed from plausible reality because no one knows what negative energy is, how to make it, or how to store it, let alone put it to use.
What’s more, the amount of negative energy you’d need to reach a place like Alpha Centauri — the nearest star system to Earth, at 4.367 light-years away — in a couple years with a 100-cubic-meter ship is truly astronomical.
“If you took the entire Earth and annihilated it into energy, that’s how much energy you’d need, except you’d need a negative amount of that, which no one has any clue how to make,” Carroll said. “We’re not taking the atoms of the Earth and dispersing them like the Death Star would do. We’re making them cease to exist.”
Then this energy has to be captured, stored, and used with 100% efficiency.
“It’s completely crazy talk,” Carroll said. “It’s not something like, ‘Oh, we need better transistors.’ This is something that is not anywhere within the realm of feasibility.”
The study states that its conclusions are speculative, admits the negative-energy figure “is, indeed, an incredible number,” and adds that “a full understanding of the true nature of dark energy may be many years away.”
However, it suggests “that experimental breakthroughs at the Large Hadron Collider оr developments in the field of M-theory could lead to а quantum leap in our understanding of this unusual form of energy and perhaps help to direct technological innovations.”
Nearly a decade on, none of these developments have panned out. The LHC has yet to find any evidence of particles that’d crack the mysteries of dark energy, nor have experiments really advanced M-theory.
But assuming negative energy could somehow be extracted, a planet’s worth of exotic matter fed into a spaceship’s warp drive engines, and a suitable destination picked out, the crew might encounter a number of show-stopping problems.
Interstellar travelers may lose control of their ship the moment they start it due to the warping of space itself. Hawking radiation — which is theoretically found at the edges of black holes and other highly warped regions of space — might roast passengers while shutting down their warp field. And slowing down may be deadly: Several light-years’ worth of cosmic dust and gas between the origin and destination might turn into a dangerous shockwave of high-energy particles and radiation upon arrival.
“It’s possible in the sense that I can’t actually rule it out, but I don’t think it’s actually possible,” Carroll said of warp drives and faster-than-light travel. “I think if we knew physics better, we’d just say, ‘No, you can’t do that.'”

When you think of badass U.S. Presidents, you likely aren’t thinking of Herbert Hoover. In fact, he’s probably very low on your list of presidential badassery, right there with James Buchanan, Millard Fillmore, and Chester A. Arthur.
But what if you saw him and his wife fighting with the U.S. Army’s 9th Infantry, his wife brandishing a .38 Smith Wesson, to fight Chinese rebels trying to murder tons of foreigners?
Before he became President of the United States, Hoover was the general manager for the Chinese Engineering and Mining Corporation. He and his wife lived in China around the turn of the 20th Century and was generally well-regarded by the Chinese for his progressive views regarding their treatment.
But the Boxer Rebellion soon broke out in 1900, a semi-spiritual effort to rid China of foreigners, often by ridding their heads of their bodies. It spread from sporadic acts of violence against Western influence to a full-on peasant uprising. That’s when the Chinese Empress Dowager Tsu’u Hzi declared war on all foreign nations at the same time.
Good call, lady.
The powers allied against China included France, Germany, the British Empire, the United States, Russia, Italy, Austria-Hungary, and Japan, who mobilized a multi-national force (called the Eight-Nation Alliance) to protect foreign interests and recuse the besieged foreign legations and citizens around the country.
The Hoovers were in Tianjin, and they were ready for the Boxers.
For a month, Hoover and his wife – along with the rest of the city – resisted the siege of Tianjin. Future First Lady of the United States, Lou Henry Hoover, defended herself with a Smith Wesson .38 caliber pistol while traveling from the battlefield to the hospital.
Initially, the Hoovers enlisted the 800 other Westerners and Chinese Christians (also a target of the Boxers) to maintain a defense of the west end of Tianjin. They reinforced the area with bags of grain and sugar while arming U.S. Marines and sailors who happened to be there.
Hoover was known to have rescued Chinese children caught in the crossfire during the street-to-street fighting. Both Hoovers did duty manning the barricades. It’s not known if the Hoovers — devout pacifist Quakers — actually killed anyone, but they did keep the Boxers from doing it.
The beginning of the end came as the multinational relief column — including the U.S. Army’s 9th Infantry Regiment, to this day known as the “Manchus” — arrived in Tianjin. Hoover himself led U.S. Marines, along with columns of British, French, and Japanese troops around the city. His knowledge of the area and its terrain was critical to their success there.
Later, biographer David Bruner recalled Mrs. Hoover’s account of her time in his book, Herber Hoover: A Public Life. She said she “had a splendid time during the Boxer Rebellion and would not have missed it for anything.”
Tianjin was the bloodiest battle of the entire Boxer Rebellion.
The Barrett M82, known by members of the U.S. military as the M107 .50-caliber semi-automatic rifle, is one of the military’s most beloved weapons in use today. Its service history is as storied – and as American – as the history of its inventor, Ronnie Barrett.
Before his name became synonymous with American military supremacy, Barrett was a professional photographer in his home state of Tennessee. He never studied science or engineering in college – in fact, he didn’t go to college at all. He went to Murfreesboro High School before going out and starting a photography studio.
That all changed during the course of his usual work.
And many, many U.S. and allied troops are better off for it.
In 1982, Barrett was snapping a photo of a river patrol gunboat during a military exercise on the Stones River near Nashville, Tenn. Mounted on that boat were two M2 Browning .50-caliber machine guns. The size of the ammunition cartridge got Ronnie Barrett thinking. He was “wowed” by the Ma Deuce, but he wanted to know if the .50-caliber cartridge could be fired from a shoulder-mounted sniper rifle.
He was out on the water that day to snap promotional photos for the Browning Firearms Company, but he ended up starting a rival firm, one that would become as closely-linked with the U.S. military as Browning.
The photo also won a first-place award from the Tennessee Professional Photographers Association. No joke.

Barrett went home and began work on a 3D sketch of what would soon become the Model 82A1 – M107. Within just seven years, Barrett was able to sell his powerful sniper rifle to the Swedish military and eventually the United States Marine Corps, then the U.S. Army and the U.S. Air Force.
Not bad at all for someone with no college education, but a whole lotta vision. Welcome to Ronnie Barrett’s America, folks.
The US Army on Feb. 6, 2019, announced that it would buy an Israeli missile-defense system to protect its soldiers in a de facto admission that existing US missile defenses just don’t work.
“The U.S. Army has announced its intent to procure a limited number of Iron Dome weapon systems to fill its short-term need for an interim Indirect Fire Protection Capability (IFPC),” a US Army statement sent to Business Insider read.
Israel’s Iron Dome missile-defense system, indigenously designed with a 9 million US investment backing it, represents the world’s only example of working missile defense.
While the US, Russia, and China work on high-end missile systems meant to shoot down stealth aircraft in ultra-high-tech wars with electronic and cyber warfare raging along the sidelines, none of these countries’ systems actually block many missiles, rockets, or mortars.

On the other hand, Israel’s Iron Dome has shot down more than 1,200 projectiles since going operational in 2011. Constant and sporadic attacks from Hezbollah in Lebanon and Iranian-aligned forces in Syria have turned Israel into a hotbed of rocket and mortar activity, and the system just plain works.
Not only do the sensors and shooters track and hit targets reliably, the Iron Dome, unlike other systems, can tell if a projectile is going to miss a target and thereby save a 0,000 interceptor fire.
While the system does not run entirely without error, US and Israeli officials consistently rate the dome as having a 90% success rate on the Gaza border, one of the most active places in the world for ballistic projectiles.
But the US already has missile defenses for its forces.
The US, unlike Israel, which is surrounded by enemies bent on its ultimate destruction, doesn’t get many enemies firing ballistic missiles at its forces. Still, to protect its soldiers, the Army typically deploys Patriot defenses to its bases to protect against short-range missile attacks. In Iraq, the US Army also experimented with a Phalanx gun system that would rapid fire 20mm rounds at incoming rockets and mortars.
Overall, the US Army’s statement announcing the Iron Dome purchase made it clear that this would just be a short-term buy while the US assesses its options.
“The Iron Dome will be assessed and experimented as a system that is currently available to protect deployed U.S. military service members against a wide variety of indirect fire threats and aerial threats… it should be noted that the U.S. Army will assess a variety of options for” the long term, the statement continued.
But the Army is well aware of its own Patriot system and any planned or possible updates.
By buying an Israel system with a great track record and overlooking a US system with a checkered past, the US may have finally admitted its shortcomings in missile defense.

In 1863, Union soldiers attempted to root out deeply entrenched Confederate soldiers at Vicksburg, Mississippi. Repeated assaults failed to breach the defenses, leading to over 100 troops committing acts that would later earn them Medals of Honor for valor — including 78 soldiers who took part in a nearly suicidal attempt to build a bridge under fire.

Vicksburg was the ultimate target of Gen. Ulysses S. Grant’s campaign down the Mississippi. His assault started with a landing on the shore of the Mississippi on April 30, 1863, and he fought his way south in the battles of Port Gibson to Champion Hill and Big Black River.
Within weeks, Grant was outside Vicksburg, the city President Abraham Lincoln called, “the key to victory” and President Jefferson Davis called the “nailhead that holds the South’s two halves together.” The Confederates pulled back inside the “Fortress City.”
The defenders were crouched in a ring of forts with 170 cannons, many aimed at bottlenecks and approaches to the city. Grant hoped to take the city before the defenders could truly settle in.
“First at Vicksburg” depicts the 1st Battalion, 13th Infantry Regiment which was the only unit to reach the top of the fortifications on May 19, but even they were later thrown back.
He sent his infantry against an earthen fort named Stockade Redan on May 19, but they were repelled with 1,000 casualties. Grant spent the next two days coming up with a new plan.
He once again chose Stockade Redan, but the new plan called for two feats of combat engineering under fire. One feat was quickly erecting scaling ladders against the wall, a challenging but time-tested move. Before the ladders went up, though, a group of volunteers would need to cross a quarter-mile of open ground while under fire and construct a bridge across an 8-foot-wide ditch.
A call went out for 150 volunteers, only single-men need apply. They came and were split into three groups. The first group carried beams to span the gap, the second group carried the planks that would form the rest of the bridge, and the last group carried the scaling ladders.
These men were collectively known as “Forlorn Hope.” Their assault was part of a three-phase operation. First was a four-hour artillery barrage, then the bridge construction and ladder emplacement, and then an assault by a brigade up the ladders.
But Confederate artillery and rifle fire quickly rang out, and an estimated half of Forlorn Hope was hit and down before they reached the ditch. The survivors quickly found that, with so few people still carrying the materials, they did not have enough pieces to construct the bridge.
They scattered, some attempting to take cover in the ditch or against the stockade wall as others ran back across the open field.

Grant and his men were forced to conduct a siege that would drag on for six more weeks before the city finally surrendered. In 1894, 53 survivors of Forlorn Hope were awarded Medals of Honor for their heroism at Vicksburg, another 25 soldiers who took part in the failed effort would receive the same award in other ceremonies. Approximately 42 other Medals of Honor were awarded for actions during the siege and assaults, bringing the total to 120.
The Confederate forces had their own Medal of Honor, and Confederate Navy Capt. Issac Newton Brown received the medal for his actions on the CSS Arkansas while trying to fight past the U.S. Navy to relieve the pressure on Vicksburg.
Aluminum has served in war since ancient times, but its most common application today is as armor, allowing for well-protected but light vehicles that can tear through rough terrain where steel would get bogged down. But aluminum has an unearned reputation for burning, so troops don’t line up to ride in them under fire.

Aluminum got its start in war as alum, a salt composed of aluminum and potassium. This was one of the earliest uses of aluminum in military history. Ancient commanders learned you could apply a solution of the stuff to wood and reduce the chances it would burn when an enemy hit it with fire.
As chemists and scientists learned how to create pure aluminum in the 1800s, some military leaders looked to it for a new age of weaponry. At the time, extracting and smelting aluminum was challenging and super expensive, but Napoleon sponsored research as he sought to create aluminum artillery.
Because aluminum is so much lighter than steel, it could’ve given rise to more mobile artillery units, capable of navigating muddy lanes that would stop heavier units. Napoleon’s scientists could never get the process right to mass produce the metal, so the ideas never came to fruition.
But aluminum has some drawbacks when it comes to weapon barrels. It’s soft, and it has a relatively low melting point. So, start churning out cannon balls from aluminum guns, and you run the risk of warping the barrels right when you need them.
Instead, the modern military uses aluminum, now relatively cheap to mine and refine, to serve as armor. It’s light, and it can take a hit, making it perfect for protection. The softness isn’t ideal for all purposes, but it does mean that the armor isn’t prone to spalling when hit.
But aluminum’s differences from steel extend deep into the thermal sphere. While aluminum does have a lower melting point than steel, it also has a higher thermal conductivity and specific energy (basically, it takes more heat to heat up aluminum than it does to heat up steel). So it can take plenty of localized heat without melting away.

(In industrial applications that rely on aluminum burning, the process is usually started by burning another metal, like magnesium, which burns more easily and releases enough heat, and the aluminum is crushed into a fine powder and mixed with oxygen so that the soot doesn’t halt the reaction.)
In a book published in 1993, after the Bradley became one of the heroes of Desert Storm, he claimed that the vehicles survived because of changes made after those tests. But while the Army might have switched the locations where ammo was stored and other design details, they didn’t change the hull material.
But, again, aluminum does melt. And the few Bradley’s that did suffer extended ammo fires did melt quite extensively, sometimes resulting in puddles of aluminum with the steel frame sitting on top of it. This spurred on the belief that the aluminum, itself, had burnt.

But aluminum melts at over 1,200 Fahrenheit, hot enough that any crew in a melting aluminum vehicle would’ve died long before the armor plates drip off. Aluminum is great at normal temperatures, providing protection at light weights.
And so aluminum protects vehicles like the M2 Bradley and the M113 armored personnel carrier. The new Armored Multi-Purpose Vehicle that is slated to replace the M113 has, you guessed it, an aluminum hull. But while troops might enjoy the increased space, they’ll probably leave off any discussion of the vehicle’s material while bragging.
The comprehensive construction and upgrade of new airfields in the high Arctic has been practically completed and we are flying there and back, says Major General Igor Kozhin, leader of the Russian Naval Air Force.
Russia has over the last years invested heavily in military bases all over its wide-stretched Arctic, and there are now potent forces deployed all the way from the westernmost archipelago of Franz Josef Land to the Wrangle Island near the Bering Strait.
In addition comes the bases on Novaya Zemlya, Severnaya Zemlya and the New Siberian Island. New bases and air fields are also located on the Arctic mainland, from the Kola Peninsula to Cape Shmidt in the Chukotka Peninsula. The new base in Tiksi, was started in fall 2018 and is planned to be completed already in the course of the first half-year of 2019.
Upgrades are also in the making at the airfields of Vorkuta, Tiksi, Anadyr and Alykel.

The Navy’s northernmost air force is located in the Franz Josef Land where the Nagurskoye base offers pilots a 2,500 meter long landing and takeoff strip.
In east Arctic archipelago of New Siberian Island, the Temp airbase is about 1,800 meters long.
According to Igor Kozhin, most of the new air fields will over the next few years be operational all though the year and capable of handling all kinds of aircraft.
“We have prepared the air force command structures and established a force than is capable of resolving its appointed tasks,” Kozhin says to Krasnaya Zvezda, the newspaper owned and run by the country’s Armed Forces.
Furthermore, the Air Force has not only boosted its strength and hardware in the region, but also significantly improved its tactical capabilities, the major general underlines.
That not only includes the regional air space, but also the situation under the Arctic ice.
“We are not only talking about the air space, we are also working on breaking up the situation under the ice,” Kozhin says. “We are pretty seriously working with this. That means that the pilot, when in the air, must be able to have a full control over the situation.”
Surveillance capabilities have been improved.
“In the course of the last years we have on the request of the General Staff conducted several experiments on the development of a unified and real-time system on information-battle in the naval air force space,” the military representative says.
“This allows us to discover and eliminate threats before damage is made, the reaction time is significantly reduced and we get the possibility to neutralize the danger in its early stage.”
According to Kozhin, the Armed Forces have also managed to develop a new hard cover for airstrips that can be more efficiently applied in Arctic conditions. The new technology, that can be put on the ground in temperatures down to minus 30 degrees centigrade, has reportedly already successfully been tested in one of the Arctic airfields.
“This new material has proved itself excellent and opens a range of new opportunities that allows us to in short time restore restore the capability of the takeoff and land strip and extend its usage and heighten flight security.”
