The U.S. Armed Forces widely uses the M249 SAW light machine gun, as it’s tried and tested on the battlefield — but all weapons have limitations, as a new video from West Coast Armory shows.
To test the durability of a suppressor, a device used to mask muzzle flash and muffle sound from firearms, the guys at West Coast Armory, a Washington state-based gun range, set up the M249 on a bipod and fed a belt of 700 rounds through it.
To be clear, this qualifies as ridiculously overdoing it and is not advisable in any but the most controlled scenarios.
In the clip below, watch the suppressor get utterly destroyed and the M249’s barrel become red hot.
VA scientists are working to create a 3D-printed artificial lung that they tout as having the potential to revolutionize the treatment of Veterans affected by lung disease.
One such lung disorder—chronic obstructive pulmonary disease (COPD)—is one of the most prevalent and costliest ailments in the Veteran population.
Dr. Joseph Potkay, a biomedical engineer at the VA Ann Arbor Health Care System in Michigan, is leading the VA-funded research. It calls for making a prototype of the 3D-printed artificial lung. Potkay and his team hope to build what they call the first wearable artificial lung that is compatible with living tissue and is capable of short- and long-term respiratory support.
The lung is seen initially as a temporary measure, a bridge to help patients awaiting a lung transplant or an aid for those whose lungs are healing. Future versions could have longer-term applications, the researchers say.
Potkay says this is the first time high-resolution 3D polymer printing is being used to create microfluidic lungs with three-dimensional blood flow networks.

Microfluidic artificial lungs, a new class of artificial lungs, mimic the structure of the natural lung better than conventional artificial lungs. Tiny blood channels, some thinner than a human hair, are closer in shape and dimension to those in a person, allowing for blood flow similar to that in the human body.
The biocompatible coatings on the lung’s surface are equally important. Anytime blood comes in contact with an artificial surface, an immune response leads to hardening of the blood and clotting. Biocompatible coatings will help curtail that immune reaction.
“We hope that these microfluidic flow paths and biocompatible coatings will be more compatible with living tissue, thereby reducing the body’s immune response and increasing the lifetime of the device,” says Potkay, who is also a researcher at the University of Michigan. “The flexibility in design afforded by 3D printing gives us more freedom and thus the ease to build artificial lungs with a small size and pressure drops that are compatible for operation with the body’s natural pressures.”

When American servicemen fall and are buried, it’s generally assumed that their resting place will be their last. Whether it’s a troop who was killed in World War I and buried in an American cemetery in France or a hero brought to rest at Arlington National Cemetery, the honored dead are not to be disturbed. However, some of these fallen heroes, whose identities were once unknown, are being disinterred.
One such ceremony took place in mid-July, 2018, at the National Memorial Cemetery of the Pacific near Honolulu, Hawaii. This cemetery, also known as the Punchbowl, is where thousands of servicemen who fell during operations in the Pacific Theater of World War II and the Korean War have been buried (some prominent civilians and non-KIAs are also buried there).
The reason for disturbing this rest is a damn good one, though.

Perhaps the most high-profile disinterment for the purpose of identifying a fallen serviceman was of the Unknown Soldier of the Vietnam War, who had been interred at the Tomb of the Unknown Soldier in 1984. In 1998, evidence pointing to the identity of that soldier resulted in the decision to disturb the Tomb of the Unknown Soldier to conduct DNA testing.
In 1998, the Department of Defense disinterred the Unknown Soldier of the Vietnam War to conduct DNA tests to determine his identity,
The tests eventually led to identifying the remains asthose of Air Force First Lieutenant Michael Blassie, killed in action when his A-37 Dragonfly was shot down. Blassie’s remains were turned over to his family and he was buried in the Jefferson Barracks National Cemetery. You can see the July 2018 disinterment at the National Memorial Cemetery of the Pacific in the video below.
A new report compiled by U.S. Senate researchers warns that Russia has been emboldened by its efforts to interfere in U.S. and European elections, and calls for a stronger U.S. response to deter Moscow.
The report, released Jan. 10 by staff members of the Senate Foreign Relations Committee, listed a series of policy recommendations to counter what it called “Russian President Vladimir Putin’s nearly two-decade-long assault on democratic institutions, universal values, and the rule of law across Europe and in his own country.”
The document highlighted various efforts by European governments to counter what researchers called Kremlin policies.
For the United States, the report calls for establishing a single government body to coordinate the U.S. response to Kremlin operations, publicizing assets and wealth held by Kremlin officials and politically connected businessmen in the West, and formalizing various Russia-related sanctions programs into a single designation: “State Hybrid Threat Actor.”
Other recommendations include working more closely with U.S. allies in Europe on a joint approach to deterring Russia and cyberthreats, pressing social-media companies like Facebook and Twitter to be more transparent in political advertising, and reducing European imports of Russian natural gas and oil.
But the report also strongly criticizes President Donald Trump’s administration, saying its response has emboldened Moscow.
“Never before in American history has so clear a threat to national security been so clearly ignored by a U.S. president,” it says.
The White House did not respond to requests for reaction to the report.
In the past, Trump officials have given mixed messages about how to deal with Russia, with Trump himself espousing more conciliatory policies, while others backing stronger responses, including financial sanctions and more U.S. military weaponry for European allies.
The Republican-controlled Congress, meanwhile, has pushed forward with Russia-related legislation, largely in response to the U.S. intelligence agencies’ finding that Moscow actively meddled in the 2016 presidential election.
In August, lawmakers passed the Countering America’s Adversaries Through Sanctions Act overwhelmingly and the measure was reluctantly signed into law by Trump.
Russia has repeatedly denied any effort to interfere in the 2016 presidential election.
On Jan. 8, Deputy Foreign Minister Sergei Ryabkov rejected assertions by CIA chief Mike Pompeo that Moscow planned to meddle in the November 2018 elections that will determine whether the Republicans retain control over both houses of Congress.
The report was authored by staffers working for Democratic members of the Senate Foreign Relations Committee, and commissioned by the panel’s lead Democrat, Ben Cardin, an outspoken critic of the Kremlin.
Asked at a briefing on Jan. 9 why Republican committee staffers or members were not involved in the report, staffers insisted that Republicans would be supportive its findings and recommendations.
A contingent of more than 70 mountain troops from a motorized rifle brigade based in the North Caucasus republic of Karachai-Cherkessia is participating in the Druzhba-2018 exercises, Russia’s Southern Military District said in a statement on Oct. 22, 2018.
The military exercises are set to run through Nov. 4, 2018.
The Dryuzhba (Friendship) drills have been held annually since 2016. In 2017, more than 200 troops took part in the exercises held in mountainous Karachai-Cherkessia.
The purpose of the war games is to strengthen cooperation between the two countries’ militaries and exchange professional experience, particularly in counterterrorism.

Pakistan and Russia signed a defense cooperation agreement in 2014 that provides for cooperation on promoting international security.
The accord calls for the intensification of counterterrorism efforts and arms control activities as well as strengthening military cooperation and sharing experiences in counterterrorism operations.
Warm ties between Moscow and Pakistan’s regional rival India go back to the Soviet era, but Russia has also sought to improve relations with Pakistan in recent years.
The months and weeks leading up to separation or retirement can be exciting and terrifying. Some of you have a post-military career lined up, and others of you are faced with the overwhelming reality that there is no obvious and predictable next step.
To ensure you control as much of the career transition process as possible, you will need to do some deep thinking, self-reflection, and self-marketing to make yourself attractive to potential employers. Whether you are starting your own business, working for the government, joining a non-profit organization, or seeking employment in a private company, here are four important actions you can take to position yourself for success:
1. Define your goal and set a strategy
Defining your career goal to closely tie to the industry or job you are pursuing. For instance, if you want to be a journalist, it would help if your first job was in writing or editorial work. Your strategy might include getting connected to influencers and decision makers in journalism or publishing, demonstrating your abilities (perhaps you’ll write a blog, publish an article or write an essay showing your skills), and preparing a portfolio of your work that highlights your abilities and talents.
Next, get more detailed in your plan. Your first step might be to get lists of key publications you would like to work for, identifying the right person to contact for an informational interview (see number 3 below), and reading through their website to understand the opportunities and challenges facing that publication.
2. Make yourself findable online
As you transition out of military service (even if you will join the Guard and Reserve), your social networking will evolve. Now, more than ever, pay attention to your online presence. Recruiters, employers and hiring managers scour online profiles to find potential candidates, evaluate them, and find consistency in their values, experience, and talents.
Follow these rules to make yourself findable online:
Create a profile that genuinely represents you. From your headshot to your summary of your experiences and goals, make sure you represent your goals and values authentically. Recruiters are looking for real people with real ideas and credible experience.
Work your online networks. Platforms like Monster.com, LinkedIn, Google+, and Twitter are best used for business and career, so keep them professional. Have a plan for adding your voice to important conversations, and building your visibility in key groups and forums where recruiters for companies in your target industries participate.
Remember that everything you post is public. Nothing typed into or shared on a computer, smart phone, or tablet is private – ever! Anyone can share a screen shot of your instant message or “offline” post. Assume the hiring manager for your dream job is seeing that photo or that post… would they still want to hire you?
3. Request informational interviews
Instead of asking for a job, consider asking professionals for informational interviews. This type of meeting is an opportunity for you to spend 15-30 minutes with people in the industries, companies, or jobs you want to pursue, asking them about their field, career and insights. Because you are not asking for employment, it is a more relaxed meeting where you might inquire: “How did you get into this career?” or “Where do you see this industry headed over the next 10 years?”
4. Enlist champions
Use the contacts you make in the informational interviews, online connections, and mentors you connected with during your service to become your advocates. They can write your recommendations, introduce you to key contacts that might be helpful to your strategy, and endorse you when asked about your talents, character, and skills.
Nurture the relationship with your champions – send handwritten notes to say thank you, and let them know what you’re up to (successes and frustrations). Keep your energy level high and optimistic in your communications with them; people want to back a winner, so make sure you communicate that you are a good investment for them to support.
The transition process is not easy. Even those who have a career path lined up after taking off the uniform will find many nuances of the civilian work place different, frustrating and exciting. Start with a strategy for building your career, instead of just finding “a job” and you will reap the rewards of your hard work!
Director Paul Katis sits down for an exclusive interview with We Are The Mighty to discuss the story behind the making of ‘Kilo Two Bravo’, hitting select theaters November 13th and available on iTunes on November 10th!
Over more than 20 years in United States Army special operations, first as a Ranger and then a Delta Force operator, Dalton Fury learned that effective leaders never wait for perfect certainty to act.
Fury is the pseudonym he uses for both his nonfiction and fiction writing, since his time in the highly secretive Delta Force has required him to conceal his true identity.
In an emailed list of leadership lessons sent to Business Insider, Fury posited a hypothetical question before giving a surprising answer: “How much information or intelligence does a special operations unit need before they launch a high-risk kill or capture mission? I argue that very rarely will the intelligence picture be better than a 70% solution, and at that point action should be taken.”
Waiting for that extra 5-10% closer to 100% clarity only further closed the window of opportunity.
Fury argued that only after the American special forces and their elite allies adopted this 70% mentality were they able to finally take the steps that led to eliminating Al-Qaeda in Iraq leader Abu Musab al-Zarqawi.
And though Fury operated in extreme situations on a battlefield, he said the “pull the trigger” mentality is as necessary in an office.
To Fury, leaders of special operators (spec ops troops) and corporate managers are placed in the same situation, where they need to make decisions with limited data, resources, and time.
“Special operators aren’t required for every problem set,” he wrote. “But, special operators are expected to manage risk, get on target, figure it out, and run it down even when the picture is sketchy.”
The Navy plans to arm its destroyers and other ships with high-tech, low-cost ship-board laser weapons engineered to quickly incinerate enemy drones, small boats, aircraft, ships and missiles, service officials told Scout Warrior.
The Office of Naval Research is working on 12-month, $53-million deal with Northrop Grumman to develop a Laser Weapon System Demonstrator through three phases; the phases include an initial design phase, ground-testing phase and then weapons testing at sea aboard a Navy Self Defense test ship, a Northrop statement said.
“The company will design, produce, integrate, and support the shipboard testing of a 150-kilowatt-class solid state (electric) laser weapon system,” the Northrop statement added. “The contract could grow to a total value of $91 million over 34 months if ONR exercises all of its contract options.”
Office of Naval Research officials told Scout Warrior an aim of the developmental program is to engineer a prototype weapons for further analysis.
“This system employs multi-spectral target detection and track capabilities as well as an advanced off-axis beam director with improved fiber laser technologies to provide extended target engagement ranges. Improvements of high power fiber lasers used to form the laser beam enable the increased power levels and extended range capabilities. Lessons learned, operating procedures, updated hardware and software derived from previous systems will be incorporated in this demonstration,” Dr. Tom Beutner, director of the Air Warfare and Weapons branch, Office of Naval Research, told Scout Warrior in a written statement a few months ago.
“The possibilities can become integrated prototypes — and the prototypes become reality when they become acquisition programs,” an ONR official said.
It is not yet clear when this weapon might be operational but the intention seems to be to arm surface ships such as destroyers, cruisers and possibly even carriers or an LCS with inexpensive offensive or defensive laser weapons technology.
“It is way too early to determine if this system will ever become operational. Northrop Grumman has been funded to set-up a demo to “demonstrate” the capabilities to senior leadership, who will then determine whether it is an asset worth further funding and turning into a program of record,” a Navy official told Scout Warrior.

Both Navy and Northrop Grumman officials often talk about the cost advantages of firing laser weapons to incinerate incoming enemy attacks or destroy enemy targets without having to expend an interceptor missile worth hundreds of thousands of dollars.
Navy officials describe this as getting ahead of the cost curve.
“For about the price of a gallon of diesel fuel per shot, we’re offering the Navy a high-precision defensive approach that will protect not only its sailors, but also its wallet,” said Guy Renard, director and program manager, directed energy, Northrop Grumman Aerospace Systems.
Meanwhile, the Navy has already deployed one laser system, called the Laser Weapons System, or LaWS, which has been operational for months.
Two Defense Department artificial-intelligence experts testified on Capitol Hill Dec.11, 2018, on DOD’s efforts to transform delivery of capabilities enabled by artificial intelligence to the nation’s warfighters.
Lisa Porter, deputy undersecretary of defense for research and engineering, and Dana Deasy, DOD’s chief information officer, testified at a hearing of the House Armed Services Committee’s subcommittee on emerging threats and capabilities.
The John S. McCain National Defense Authorization Act for fiscal year 2019 directed the defense secretary to conduct a comprehensive national review of advances in AI relevant to the needs of the military services. Section 238 directed the secretary to craft a strategic plan to develop, mature, adopt and transition AI technologies into operational use.
“Today we are experiencing an explosion of interest in a subfield of AI called machine learning, where algorithms have become remarkably good at classification and prediction tasks when they can be trained on very large amounts of data,” Porter told the House panel. Today’s AI capabilities offer potential solutions to many defense-specific problems, such as object identification in drone video or satellite imagery and detection of cyber threats on networks, she said.
Deputy undersecretary of defense for research and engineering Lisa Porter.
However, she added, several issues must be addressed to effectively apply AI to national security mission problems.
“First, objective evaluation of performance requires the use of quantitative metrics that are relevant to the specific use case,” she said. “In other words, AI systems that have been optimized for commercial applications may not yield effective outcomes in military applications.”
DOD is working to address such challenges and vulnerabilities in multiple ways, she said, most of which will leverage the complementary roles of the new Joint Artificial Intelligence Center and the department’s research and engineering enterprise.
Second, Porter said, existing AI systems need enormous amounts of training data, and the preparation of that data in a format that the algorithms can use, in turn, requires a large amount of human labor.
“AI systems that have been trained on one type of data typically do not perform well on data that are different from the training data,” she noted.
The JAIC’s focus on scaling and integration will drive innovation in data curation techniques, while the Defense Advanced Research Projects Agency will pursue algorithms that can be “robustly trained with much less data,” Porter said.
“The high-performance computing modernization program is designing new systems that will provide ample processing power for AI applications on the battlefield,” she added.
Department of Defense Chief Information Officer Dana Deasy.
Countering adversarial AI is one of the key focus areas of DARPA’s “AI Next” campaign, she emphasized. “Ultimately, as we look to the future, we anticipate a focus on developing AI systems that have the ability to reason as humans do, at least to some extent,” Porter said. “Such a capability would greatly amplify the utility of AI, enabling AI systems to become true partners with their human counterparts in problem solving. It is important that we continue to pursue cutting-edge research in AI, especially given the significant investments our adversaries are making.”
Three themes of JAIC effort
Deasy detailed the JAIC and highlighted three themes of its effort.
“The first is delivering AI-enabled capabilities at speed,” he said. “JAIC is collaborating now with teams across DOD to systematically identify, prioritize and select mission needs, and then rapidly execute a sequence across functional use cases that demonstrate value and spur momentum.”
The second theme is all about scale, he said.
“JAIC’s early projects serve a dual purpose: to deliver new capabilities to end users, as well as to incrementally develop the common foundation that is essential for scaling AI’s impact across DoD,” he explained. “This means [the use of] shared data, reusable tools, libraries, standards, and AI cloud and edge services that helped jumpstart new projects.”
The third theme is building the initial JAIC team.
“It’s all about talent,” he said. “And this will be representative across all the services and all components. Today, we have assembled a force of nearly 30 individuals. Going forward, it is essential that JAIC attract and cultivate a select group of mission-driven, world-class AI talent, including pulling these experts into service from industry.”
In November 2018, before more than 600 representatives of 380 companies, academic institutions and government organizations at DOD’s AI Industry Day, Deasy said, he announced that the department had achieved a significant milestone: “JAIC is now up and running and open for business.”
Do you still love fitness? Are you transitioning out of the military and thinking about what the next steps of your future career will be?
Think about a hobby you love. Can you make your hobby into a job or even just a part-time position for starters?
How about a job in the fitness industry? There are many veterans in the fitness industry, including myself, a tactical fitness writer. But writing is far from the only option in the multibillion-dollar fitness business. From personal trainers, gym owners, strength coaches, supplement affiliates, inventors and program developers to athletes who compete in all types of competitions, there are plenty of fitness-related career paths.
If fitness is part of your life or used to be, consider finding that love again. You might find something inside you that reconnects with the world you left behind when you first joined the military.
Here are some of the many fitness career paths that can help you get moving again, fine-tune your fitness knowledge and skills, and teach people who need your motivation, passion and example.

1. Group Trainer
One of the easier ways to get involved in training people is to lead a group at an established fitness center. Or you could build your own outdoor fitness boot camp program, especially if the weather permits most of the year. A group training instructor could be as basic as a boot camp fitness class or a learned training program on spin bikes, yoga, kickboxing, Zumba, barre, aquatic fitness or CrossFit. No matter what you pick, these are fun ways not only to teach others, but to get your own workout accomplished with a group of people who need your leadership. It can also be a good supplemental income if you can spare an hour or two a few days a week.
2. Personal Trainer
Like the title suggests, this business model is more personal, and you get to really know and develop training programs for the goals, needs and abilities of a client. Personal training is also better paying than group fitness. You can offer personal training as part of an existing fitness center or set up your own hustle and train people at their own homes or in an outdoor area.
3. Online Fitness Business
If you like to create content for people to read or view, you may find a promising business model with a website store and social media. Whether it is through your own products, articles and videos or using an affiliate model, you can make significant income online with just a little bit of technology skill.

4. Invent a Fitness Device
Two friends of mine created companies around their inventions. Randy Hetrick of TRX and Alden Mill of Perfect Pushup fame both created products that fit into the fitness industry very nicely and maybe even revolutionized it to some degree.
5. Can You Still Compete?
Many veterans are still going hard-core after service and compete in professional racing and sports from CrossFit Games, to the Olympics and Paralympic Games, to becoming sponsored and professional athletes in the racing world. Moving that athletic fame into social media and internet fitness businesses is a great way to continue training and helping others, as well as earning a living.
Fitness is important for the transitioning veteran. Whether you decide to make fitness part of a way to make extra income, or you just get involved in volunteer coaching in your community, you will find that the physical activity you do and the coaching and teaching you provide are helpful to you and others.

Gurkhas are known as some of the fiercest warriors ever to take up arms. These soldiers from Nepal regularly receive high valor awards from both Britain and India because of their bravery, and they are skilled, in one case defeating Taliban ambushes while outnumbered over 30 to 1. They fought in British forces in almost every major conflict of the 20th and 21st centuries including both World Wars and in Iraq and Afghanistan.

The Kathmandu Valley is surrounded by the Himalayan mountains. In 1767, the three valley kings had been fighting each other for years and suddenly realized that the Gurkha Army was invading. The Gurkha conquered parts of the valley and began a siege of one of the kingdoms’ capitals.
In order to prevent conquest by the Gurkha, the Kathmandu kingdoms asked British officers serving nearby in the East India Company armies for assistance.
Capt. Captain George Kinloch led 2,500 soldiers with then-modern weapons into the valley to prevent the Gurkha expansion but failed to properly plan. Battlefield defeats against the Gurkha were made worse by disease and inadequate medical supplies.
A wave of desertions and a two-pronged assault launched by the Gurkha cinched the deal and Kinloch was forced to retreat from the valley. By 1768, the Gurkha armies were able to declare the valley and many of the surrounding mountains to be their own new nation, Nepal.
Over the next 46 years, both the Gurkha and the British expanded their areas of influence and control, creating a number of friction points both between themselves and other nations.
These friction points triggered the Anglo-Nepalese War in 1814. The Gurkha possessed much better knowledge of the terrain and plenty of veteran fighters. The British had numerical and technological advantages with tens of thousands of Indian soldiers equipped by the East India Company.
Despite numerous British advantages, the campaign went badly for the first year. One of the generals was killed in a small skirmish the day before war was officially declared. Other generals were known for cowardice on the battlefield, failing to attack when ordered. One even walked out of his camp.
Check the WATM podcast to hear the author and other veterans discuss how the Gurkhas became feared warriors.
Still, some of the British forces fought valiantly. Col. David Ochterlony led a siege at the primary Gurkha fortress in 1815 while another colonel and 2,000 men captured a secondary fort. The Gurkha eventually surrendered the main fort to Ochterlony and peace documents were drafted.
The Gurkha leaders failed to accept the peace treaty and the British launched a second campaign to settle the matter, this time with Himalayan soldiers marching into the valley beside the British and Indian troops. This second campaign in 1816 made it nearly to the capital of Kathmandu before the Gurkha finally accepted the peace treaty.
They served with distinction in wars against the Sihk, but they were truly lauded for actions in the Indian Mutiny of 1857. Gurkha soldiers served as the final guard of Brtish military and government leaders as rebelling Indian troops attempted to kill them.
While the British were successful in re-establishing rule in India, atrocities committed by the East India Company and their soldiers during the conflict led to the British crown abolishing company control of India.
When the crown established direct control of India, the Gurkha regiments were incorporated into the British Army.
Since the breakup of the British empire, Gurkha soldiers have been able to choose to fight in the British or Indian armies which still contain “Gurkha” and “Gorkha” units respectively. They are known for their khukuri knives which feature a curved, 18-inch blade.
In the British military, Gurkha men were limited to serving as enlisted soldiers in Gurkha units until recently. Now, they can try out for both slots in officer training and coveted positions in special operations.
The USS Illinois (SSN 786) was commissioned Oct. 29 in a ceremony at Groton, Connecticut.
The Virginia-class fast attack submarine can carry 12 Tomahawk cruise missiles to strike at targets on enemy shores, or it can switch some of its missiles out with other payloads to deliver special operators or mines to contested areas around the world.
Conventional periscopes don’t exist on the Illinois or other Virginia-class submarines. Instead, they feature photonic masts that send video and other image data to screens throughout the ship.
The Illinois is a Block III-version of the Virginia class, and features a horseshoe-shaped sonar instead of the older, spherical sonars. And, instead of packing 12 vertical missile tubes, Block III subs carry two sets of six missiles in Virginia Payload Tubes. If the Navy adopts a new missile in the future, the VPTs allow the Illinois to more easily switch to the new weapon.
The boat carries an S9G pressurized water reactor. The nuclear reactor powers the vessel for its entire lifecycle without ever needing refueling. The pump-jet propulsors push the boat forward are quieter than a traditional propeller.
Missions on the Illinois can go on for three months or longer, and the crew can spend nearly the entire time submerged.
