The engineers at the Carnegie Mellon University developed a robot prototype that could theoretically perform many, if not all, ground missions.
“By creating a system that can be readily reconfigured and that also is easy to program, we believe we can build robots that are not only robust and flexible, but also inexpensive,” said Howie Choset, the inventor of this robotic system in a Carnegie Mellon University news article. “Modularity has the potential to rapidly accelerate the development of traditional industrial robots, as well as all kinds of new robots.”
Watch how the robot is assembled like Legos to create a snake, a walking six-legged machine, and other wild things:
The C-130 has a long legacy of getting troops and cargo from point A to point B. However, while the Hercules is versatile (from a gunship to wielding the powers of the Shadow) and a legend, let’s face it, it does have limitations. Part of it is the fact it can carry 22 tons at most in the C-130J-30 version.
So, Airbus decided to try to address that shortcoming. The result is the A400M Atlas, and like Japan’s C-2 transport, it is intended to fit in the niche between the C-130 and the C-17.
The difference is that while Japan chose to build a scaled-down C-17, Airbus decided that the answer involved giving the C-130 a “steroid” boost, just as Japan did with the F-16.
The result is a plane that lists more (37 tons compared to 22), has more endurance (4,800 nautical miles to 2,100), and which can still land on rough fields like the C-130. The C-17, according to an Air Force fact sheet, needs a 3,500 foot runway.
So, what exactly does this mean? The cargo hold is 58 feet long, 13 feet high, and 13 feet wide. Airbus says the plane can carry an NH90 or CH-47 helicopter, or most infantry fighting vehicles.
And we’re not talking a Stryker — we’re talking a heavy infantry fighting vehicle like Germany’s Puma.
The A400M will also be able to haul troops, and unlike the C-2 or C-17, it is also capable of being used as a tanker. Yeah, like the C-130, the Atlas is capable of topping up fighters on a ferry run or when they are headed out to carry strikes.
Below, you can see the Atlas do a move that few transports can do. But ultimately, this transport’s going to be doing a lot of hauling. Already, 46 are in service, with a total of 174 ordered.
The Orlando Police Department is crediting a Kevlar helmet with saving the life of an officer who responded to the deadliest mass shooting in U.S. history.
The department on Sunday posted a picture of the officer’s helmet showing damage from being struck by a bullet during the incident. The green paint is chipped, parts of the fabric is torn and there appears to be a small hole.
“Pulse shooting: In hail of gunfire in which suspect was killed, OPD officer was hit. Kevlar helmet saved his life,” the department tweeted on its Twitter account. The make and model of the helmet weren’t immediately known.
The officer, who wasn’t identified but was presumably a member of the department’s SWAT team, suffered an eye injury, Danny Banks, special agent in charge of the Florida Department of Law Enforcement’s Orlando bureau, told CNN.
The incident was the deadliest mass shooting in American history, with at least 50 individuals confirmed dead and another 53 injured. The shooting began around 2 a.m. Sunday at a packed Orlando nightclub called Pulse, which caters to the LBGT community.
The gunman, who was shot and killed in a shootout with police, pledged allegiance to the Islamic State in Iraq and Syria, or ISIS, during a 911 call, CNN reported. He was identified as Omar Mateen, a 29-year-old U.S. citizen and Muslim who lived in Port St. Lucie, Florida, and whose parents were of Afghan origin, Fox News reported.
“This was an act of terror and an act of hate,” President Barack Obama said during a press conference at the White House.
Obama credited first responders with preventing an even deadlier attack by quickly responding to the scene and rescuing hostages. Mateen reportedly held dozens of people hostage until about 5 a.m., at which point the Orlando Police Department’s SWAT team raided the building using an armored vehicle and stun grenades, and killed him, The New York Times reported.
“Their courage and professionalism saved lives and kept the carnage from being worse,” Obama said. “It’s the kind of sacrifice our law enforcement professionals make every day.”
Warfighting is not a 9-to-5 job. War is waged at all hours of the day. While getting into a firefight in broad daylight means you won’t need to sling NVGs over your face to see clearly, it’s arguably more convenient to raid compounds when the enemy has their pants down — figuratively and, occasionally, literally. The two tools that make night raids possible are night vision goggles and the PEQ-15, which is basically a rifle-mounted IR laser-pointer that can be seen through NVGs.
Until recently, America and its allies have been unrivaled in nighttime operations. Now, the Taliban Red Group has been spotted using stolen and black-market NVGs while they overrun checkpoints and police bases. Retired Army Col. Steven Bucci of the Heritage Foundation told Military Times that this was, in his view, “kind of inevitable.”
“When we do these kinds of missions, we basically try and buy [local forces] the same kind of equipment they already have,” Bucci said. “But, you know, we are trying to upgrade these folks and give them an advantage, so we do introduce them to things like night vision devices and maybe longer range optics for weapons, and you run the risk that they’re going to fall into enemy hands.”
Keep in mind, NVGs and weapon-mounted IR lasers are still hard to come by for the Taliban Red Group and even more so for the average terrorist. And the gear that they do acquire is typically far below our “lowest bidder” quality.
But this does throw a wrench in the well-oiled system that America and its allies have grown accustomed to fighting within. Just knowing that even one terrorist might be able to see what our warfighters see means a huge change of strategy is coming. NATO’s reliance on IR markings for everything from helicopter landing sites to troop positions will need to be adapted.
The easy solution here is for troops to maintain light discipline for IR, just as they do with every other light used during night operations. Though the darkness of night may no longer be an impenetrable concealer, we maintain the technological edge over those getting their first glimpse behind the curtain.
Quick, what countries have the second- and third-largest carrier forces in the world?
Number one, of course, is the United States with ten carriers and one on the way, even as it scraps as many as eight older ones (Forrestal, Saratoga, Ranger, Independence, Kittyhawk, Constellation, Enterprise, and John F. Kennedy).
The second-largest is . . . Japan, which has three carriers (actually called “helicopter destroyers”) in service and a fourth on the way. The third-largest carrier force belongs to India, with two in service and one on the way.
Surprised? Don’t be. India’s navy has long been one to reckon with, partially due its heritage under British rule. That Royal Navy DNA makes India a serious naval power, and India has managed to mesh technology from a variety of countries to create their navy.
INS Viraat is the former HMS Hermes, a veteran of the Falklands War. Viraat displaces about 24,000 tons and carries about two dozen aircraft. Viraat is slated to retire soon after the new Vikrant enters service. The Viraat is a V/STOL carrier, along the lines of those in service with Thailand, Spain, and Italy. Viraat is likely to stick around until 2020 — impressive, given that she was first commissioned in 1959 by the Royal Navy.
The other active carrier, INS Vikramaditya, is the former Russian carrier Admiral Gorshkov. When she entered service with the Soviet Navy as Baku, she was originally designed to operate Yak-38 Forgers and Ka-27 Helix helicopters. After the Cold War, Russia needed cash, and India took the chance to buy the Gorshkov. After a lengthy refit following her 2004 (which was a soap opera in and of itself), the Vikrmaditya entered service in 2013. Vikramaditya displaces 45,000 tons and operates three dozen aircraft.
The carrier on the way, INS Vikrant, is being built in India. Intended to displace about 40,000 tons, she can carry 40 aircraft and will enter service in 2018. She is the second carrier to carrythe name, the previous Vikrant being a British-built light carrier that served with India from 1961-1997. The first Vikrant was a museum from 2001 to 2012 before her deteriorating condition forced the Indian Navy to sell her for scrap.
The INS Viraat is the last British-built ship serving with the Indian Navy, and is one of the oldest aircraft carriers in service in the world.
India’s naval aircraft are quite diverse, as well. India operates British Sea Harriers (the Mk 51 version) from the Viraat, along with Sea King helicopters (an American design customized by the Brits) and Dhruv helicopters designed and built in India. The Vikramaditya operates Russian-designed Ka-28 and Ka-31 Helix helicopters, MiG-29K Fulcrums from Russia, and Indian-built Tejas aircraft, a mix that will also be seen on the new Vikrant when it starts trials later this year and enters service in 2018. From land, India’s maritime patrol inventory features not only the modern P-8, but Russian Il-38 “May” and Tu-142 “Bear F” aircraft as well.
Boston Dynamics has come out with a new version of its Atlas robot that is more mobile, more agile, lighter, quieter, and doesn’t require a power tether.
The new robot was introduced in a YouTube video this morning where it was shown escaping a building and marching through the snow:
Then it stacked boxes like some sort of Robo-POG:
Like other POGs, the Atlas was bullied pretty harshly on the job:
The new generation Atlas weighs only 180 pounds, approximately half the weight of its 330-pound predecessor. It is powered by onboard batteries and can navigate obstacles that tripped up earlier Atlas robots at the DARPA Robotics Challenge.
Boston Dynamics has withdrawn from the DARPA challenge to focus on building commercially-viable robots, meaning they might try to sell the robot to the military or other buyers within the next few years.
Still, the Atlas is far from reaching the battlefield. The new improvements could get it ready to serve behind the lines, but it’s about as noisy as the BigDog robot which was shelved by the Marine Corps for being too loud. And there are no signs that it’s ready to carry its own weapon.
For now, developers will probably continue to target disaster response and similar missions.
The Colombian military on Friday activated the elite Command Against Drug Trafficking and Offshore Threats (CONAT) unit. CONAT will be comprised of 7,000 troops and its purpose will be to fight narcos, rebels financed by drug trafficking and other illegal activities and which operate across the borders of Colombia and the region, and other organized gangs.
President Ivan Duque, speaking to the troops at the sprawling army base at Tolemaida in central Colombia, described the new unit as “historic.” Meanwhile, the unit displayed aircraft and armored vehicles in a show of force among the troops.
The force, Duque said, will be tasked with “subduing, beating and subjecting the structures of drug trafficking and the… threats linked to the illegal exploitation of minerals, trafficking of species, of persons and, of course, to any transnational form of terrorism.”
“The unit was born to hit, repress, and break down the structures of drug trafficking and transnational threats linked to illegal mining, the trafficking of wildlife, and people, and — of course — any transnational form of terrorism,” President Duque said at the event.
Colombia, considered the world’s largest producer of cocaine, had over 380,000 acres of the coca crop in 2019. That is an area larger than the combined bases of Fort Hood, TX and Fort Bragg, NC, the U.S. military’s two largest bases.
One controversial development is that Colombia could restart aerial fumigation of coca fields with herbicide glyphosate soon, Defense Minister Diego Molano said.
The last active rebel group in Colombia, the National Liberation Army (ELN), finances its operations through drug trafficking, kidnapping, illegal mining, and extortion. Duque said that the unit will pursue the ELN and ex-FARC rebels who had rejected the 2016 peace deal “without qualms.”
“Soldiers, it is a morally necessary, morally correct battle… Let’s go for the defense of Colombia!” Duque added.
The long drug war, as well as a decades-long insurgency, left more than 260,000 dead and have displaced millions of Colombian civilians.
That prompted Venezuelan strongman Nicolas Maduro to rattle his saber and to “respond forcefully” although Colombia made no mention of crossing the border. Maduro, who is prone to making grand pronouncements, said that he ordered the military forces to “clean the barrels of our rifles to answer them at any level we need to answer if Ivan Duque dares violate the sovereignty of Venezuela.”
Colombia has broken off diplomatic ties with Venezuela since 2019 when opposition leader Juan Guaido was recognized as the interim president. Maduro ran a show election that was rigged. The European Union (EU), and the G7 group, Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States, joined the EU in rejecting the results of the elections and denounced them as not “comply[ing] with international standards.”
Colombia has long accused the leftist government of Venezuela of supporting the terrorist insurgents of ELN and FARC. Venezuela has denied this.
No matter how hard you try and avoid it, vehicles get stuck in the mud. It can even happen to an Abrams tank. Sometimes, as with the case of the Abrams, the vehicle is able to escape the sticky situation on its own, but what happens when the vehicle can’t manage to get free on its own devices?
Thankfully, there’s a way to handle that situation. The United States Army (and the United States Marine Corps) has a vehicle designed to help others get out of the mud and get the supplies it is hauling to the troops. That vehicle is the M984 Wrecker, part of the Heavy Expanded Mobility Tactical Truck family.
According to OshKosh Defense, the latest version of this tactical tow truck is the M984A4. It has a crew of two, a top speed of 62 miles per hour, and can go 300 miles on a 155-gallon tank of gas. You read that right; it gets really sucky gas mileage — a bit less than two miles per gallon.
But here’s the capability that you get in exchange for guzzling gas: The M984A4’s recovery winch can haul 30 tons, which is enough to get most vehicles out of a muddy situation. Its crane hauls seven tons. It can retrieve objects weighing up to 25,000 pounds. This truck is a tactical, AAA-roadside-assistance machine, and it weighs less than 55,000 pounds, meaning it can be hauled by C-130 Hercules transport planes.
Check out the video below to watch an M984 crew practice getting a vehicle out of the mud at Fort McCoy:
Aircraft carriers are symbols of American military might, and, recently, a Chinese military professor caused a stir by calling for China to sink two of them to crush America’s resolve.
That’s certainly easier said than done.
The US military conducted a “Sink Exercise” test in 2005, using the decommissioned USS America for target practice to test the defensive capabilities of US carriers in order to guide the development of future supercarriers. The ship was bombarded repeatedly and hammered in a variety of attacks.
The carrier withstood four weeks of intense bombardment before it was finally sunk, according to The War Zone.
These leviathans of the seas are beacons of American power for a reason. China could knock one of the US’ 11 carriers out of the fight, but sinking one of these 100,000-ton warships is another thing entirely. That’s not to say it can’t be done. It’s just no simple task, experts told Business Insider.

“It wouldn’t be impossible to hit an aircraft carrier, but unless they hit it with a nuke, an aircraft carrier should be able to take on substantial damage,” said retired Capt. Talbot Manvel, who previously served as an aircraft engineer and was involved in the design of the new Ford-class carriers.
At 1,100 feet long, carriers are floating nuclear power plants, fuel tankers, bomb arsenals, and an airfield stacked atop each other like a layered cake. They are then surrounded by cruisers and destroyers to defend them from missiles, fighters, and torpedoes — even if that means sacrificing themselves.
China can bring a lot of firepower to a fight.
The Chinese military has a lot of different weapons it could throw at a US carrier in a war.
China has its “carrier killer” anti-ship ballistic missiles, such as the DF-21D and the DF-26, which are capable of carrying both conventional and nuclear warheads, as well as a variety of anti-ship cruise missiles and torpedoes.
China would likely use missiles to suppress the carrier, using ballistic missiles to damage the air wing’s planes and wreck the flight deck, where planes launch and land. Weapons like cruise missiles, which can strike with precision, would likely be aimed at the hangar bay, superstructure, and maybe some of the airplanes, Bryan Clark, a former US Navy officer and defense expert at the Center for Strategic and Budgetary Assessments (CSBA), told Business Insider.
These targets are all far above the carrier’s waterline and are meant to knock the carrier out of the fight.
“If they really wanted to sink the carrier, they might have to turn to a torpedo attack,” he added. “Torpedo defense is hard, not really perfected, and so [torpedoes] actually end up being the more worrying threat.”

US carriers are behemoths that are built to take a hit.
Displacing more than 100,000 tons, the US Navy’s Nimitz-class aircraft carriers are among the largest warships ever built. Their ability to take a beating “is a function of both their size and the compartmentalization of the carrier,” Clark explained.
“In the case of the USS America, the size alone resulted in it being pretty survivable,” he said before calling attention to some other aspects of the powerful ships.
Each carrier has a number of main spaces, which the crew would try to seal off should the carrier take a hit below the waterline, say from a torpedo. The ship is so incredibly large that it would take a number of these compartments filling up with water for the ship to sink.
The type of steel used on the ships also makes them difficult to penetrate, Manvel said. “It has an underbottom and side protection of several layers of steel.” There are also “voids that allow for warhead gas expansion.”
The extra armoring is also designed to keep damage from detonating the ship’s weapons magazines, where bombs and missiles are stored.
Additionally, the US Navy pays attention to how it moves weapons around the ship, keeping these bombs and missiles as protected as possible. And steps have been taken to reduce the number of hot surfaces that could ignite.
There are also a lot of redundant systems, which means that critical systems can be rerouted, making it hard to take out essentials, such as the propulsion system, which would leave the ship dead in the water if destroyed. As long as the ship can move, it can retreat if necessary.
“Given enough time and weapons, you can sink a carrier. But, if you have defenses, people doing damage control, and propulsion, the carrier can take damage and drive away to eventually come back,” Clark told BI.
US carriers “can take a lick and keep on ticking,” Manvel, who taught at the US Naval Academy, said.
The Nimitz-class aircraft carrier USS Abraham Lincoln (CVN 72) launches a rolling airframe missile (RAM).
US carriers and their escort ships are armed to the teeth.
Carriers and their escort ships are armed with sonar and torpedoes to prevent the stealthy boats from getting close enough for a torpedo attack. And the battle group is also armed with electronic countermeasures and kinetic interceptors for missile defense. They also have various close-in weapons systems to strike at incoming threats as a last resort.
Submarines are their gravest threat to sinking. Russian subs, for instance, are often armed with 1,000-pound torpedoes that were designed to destroy carrier groups, and it’s conceivable that enough fired at once and on target could sink a carrier.
For just this reason, the US has put a lot of effort into anti-submarine warfare, so US carrier strike groups have “the ability to put weapons on submarine contacts very quickly,” Clark told BI. Escort ships can launch torpedoes or rocket-fired torpedoes, and SH-60 helicopters can drop torpedoes or sonobuoys to track submarines.
The US has also put a greater emphasis on electronic warfare to prevent US carriers from being actively targeted by enemy missiles. The Chinese could “launch a weapon, but it may not be accurately targeted enough to actually hit” a moving carrier from 1,000 miles away, Clark further explained.
There is also a keen interest in improved missile-defense capabilities. “There are lots of ways to shoot it down with kinetic interceptors, like the SM-6, SM-2, Rolling Airframe Missile,” he added.
Of course, there is also the air wing, which could include up to sixty fighters, as well as a number of jammers, helicopters, and early-warning aircraft. “We have a pretty robust air wing that can go hundreds of miles out to provide a buffer for incoming stuff. It would take a lot to get through that,” Manvel said.

American carriers are never alone in hostile waters.
“It’s important to put the carrier where it is least at risk … surrounded by the battle group,” Manvel said.
US aircraft carriers are surrounded by smaller ships, known as escorts. They sail in carrier strike groups consisting of at least one carrier, one cruiser, and one or two destroyers and are capable of unleashing a lot of firepower when needed.
They are exceptionally well defended. “You have to launch hundreds of weapons at the carrier strike group to even get a few of them through,” Clark explained. That doesn’t mean a strike group can’t be overwhelmed, though.
There’s a good chance China has the ability to do that. At a recent talk at The Heritage Foundation, Clark explained that China could hurl around 600 missiles downrange at a carrier group, which could, on a good day, down roughly 75% of the incoming Chinese weapons.
This, however, creates a dilemma for the Chinese military. The People’s Liberation Army has to make the hard decision on how many weapons it will throw away just to knock a carrier out for a few weeks, assuming it has merely been damaged and not sunk.
“Those weapons are gone. They don’t have them for some other part of the fight,” Clark said. “Maybe that is worth it to them. Maybe it’s not.”
And it’s likely in a war that the US would destroy these missile batteries with bombers and long-range missiles before it sends a carrier into their range.

To strike a killing blow, China has to get close, really close.
China has decent torpedoes, and their submarines are increasingly capable. But whether or not they are good enough to slip past the defenses of a carrier strike group to deliver the kill shot to a US carrier is debatable.
In 2006, a Chinese Song-class submarine reportedly managed to skirt the defenses of the USS Kitty Hawk strike group, surfacing within firing range of the carrier as it sailed through the East China Sea, according to a report by The Washington Times, some details of which have been called into question. The incident reportedly caused the US Navy to reevaluate its approach to Chinese subs.
The US Navy can put a lot of fire on a submarine very quickly, and because submarines tend to be rather slow with limited defenses, the enemy submarine could retreat only once it was spotted.
“Once a submarine has been detected and you start throwing weapons at it, it pretty much has to leave because it is too slow to evade, it doesn’t have a lot of self-defense, and it doesn’t have the sensors necessary to stand and fight,” Clark told BI.
The big question is: Will the US Navy strike group be able to spot an enemy submarine before it manages to get a shot off?

The U.S. Air Force just flew its first test flight of the AGM-183A Air Launched Rapid Response Weapon, a hypersonic weapon Lockheed Martin says it will continue to ground and flight test over the next three years.
The weapon, known as ARRW (pronounced “Arrow”), flew on a B-52 Stratofortress bomber aircraft on June 12, 2019, at Edwards Air Force Base, California. The tests were aimed to gather data on “drag and vibration impact” to the weapon as well as the performance of the carriage bay on the aircraft, the service said. The Air Force released photos of the flight via Twitter on June 18, 2019.
As part of a rapid prototyping scheme, the Air Force has been working with Lockheed, the prime contractor, to develop the hypersonic tech that would move five times the speed of sound as the Pentagon races to win the global race for new hypersonic technologies.
Lockheed officials touted the Air Force’s first flight here at the Paris air show.
“This captive-carry flight is the most recent step in the U.S. Air Force’s rapid prototyping effort to mature the hypersonic weapon, AGM-183A, which successfully completed a preliminary design review in March,” Lockheed officials said in a release. “More ground and flight testing will follow over the next three years.”
(U.S. Air Force)
Joe Monaghen, spokesman for Lockheed’s tactical and strike missiles and advanced programs, told Military.com that the first test of ARRW represented a milestone that paved the way for future flights and continued integration.
While the Defense Department is pursuing multiple avenues for hypersonic technologies, the variety will give the Pentagon better selection “to determine what works best operationally, across the different branches and mission sets,” Monaghen said.
Boeing Co., manufacturer of the B-52, said the recent test shows that the Cold War-era bomber can operate for years to come despite its age.
(U.S. Air Force)
“This recent success put the [Air Force] well on its way to the live-launch testing of an extraordinary weapon soon,” said Scot Oathout, director of bomber programs at Boeing, in a statement. “The future B-52, upgraded with game-changing global strike capability, such as ARRW, and crucial modernizations like a new radar and new engines, is an essential part of the [Air Force’s] Bomber Vector vision through at least 2050.”
The Air Force awarded a second contract to Lockheed in August 2018 — not to exceed 0 million — to begin designing a second hypersonic prototype of ARRW. The Air Force first awarded Lockheed a contract April 2019 to develop a separate prototype hypersonic cruise missile, the Hypersonic Conventional Strike Weapon (HCSW).

The Air Force‘s Airman Battle Uniform is getting its official send-off. On Thursday, airmen will be required to retire their old “Tiger Stripe” camouflage for good and switch to the Operational Camouflage Uniform, or OCP. The service has spent three years phasing in the Army‘s service duty uniform.
The Air Force approved the OCP to be worn full-time beginning Oct. 1, 2018, with the expectation that all airmen and Space Force guardians would make the complete changeover by April 1, 2021, after wearing the Airman Battle Uniform, or ABU, for more than a decade.
The OCP already has a history with the service.
Since 2012, nearly 100,000 airmen have worn the uniform when deployed overseas to places like Afghanistan or while operating outside the wire, Maj. Gen. Robert LaBrutta, then-Air Force director of Military Force Management Policy and deputy chief of staff for Manpower, Personnel and Services, said in 2018. LaBrutta retired in 2019.
Air Force Special Operations Command members were some of the first to don the OCP, along with some Security Forces units, LaBrutta said at the time.
Service member feedback played a big role in the decision to switch to the OCP, top officials have said. Airmen have expressed on social media that moving to a single combat uniform for the service couldn’t come soon enough.
In 2013, The Washington Post reported that there were 10 different types of military camouflage uniforms in use, depending on service and where troops were stationed.
The ABU’s “tiger stripe” pattern was supposed to pay homage to camouflage used during the Vietnam War, according to the Post.
But early iterations “looked slightly off” from one uniform to the next, with multiple shades making up the pattern, according to Master Sgt. Mike Smith, who wrote a farewell tribute to the ABU earlier this year. Smith serves at the I.G. Brown Training and Education Center at McGhee Tyson Air National Guard Base in Tennessee.
“Not since leisure suit wearers were cool has an outfit been so disliked and oppositely loved,” he said in a release. “One opponent compared its camouflage design to an over-patterned couch; another advocate hailed its unique ability to channel the wind down her sleeves, from one arm to the other while driving down the road — she will miss that.”
Airmen at the Tennessee base got together to say goodbye to the ABU one last time March 29, taking selfies in the tiger stripe.
“We’ve come a long way in this uniform, here and deployed,” said Chief Master Sgt. Steven Durrance, the enlisted professional military education center commandant at McGhee Tyson.
“It’s important to capture this moment and take time for our heritage, who we are, and where we come from,” he said in a separate release.
The service will donate leftover uniform gear associated with the ABU to junior ROTC programs across the country, service officials have previously said.
The Army Combat Capabilities Development Center (CCDC) Research Lab is testing a new suppressor with an integrated muzzle brake that will help soldiers maintain accurate and quiet fire on the enemy in future battlefields. This new device is aptly named “Smuzzle.”
Smuzzle’s design was originally meant for the Army’s 155mm howitzers, yet the inventors turned afterward to one of the army’s most common automatic weapons, the M240B. Greg Oberlin, Daniel Cler, and Eric Binter, the inventors of the new equipment, were trying to reduce recoil and muzzle flash while also reducing the sound from the machinegun.
Standard suppressors for the 7.62 mm caliber were unable to withstand the intense heat of the M240B (which is known as “the pig” by the soldiers who carry it in the field).
The device is currently undergoing testing on the M240B with the NATO 7.62×51 mm round as well as the Next-Generation Squad Weapon Technology 6.8mm round. (The 6.8mm round reduces the volume at the shooter’s ear by half, volume downrange by 25 percent, and recoil by a third said Oberlin, a small arms engineer at the Army’s CCDC Army Research Lab.)
The three inventors began their research back in 2007. They were recently awarded a 20-year utility patent with the Army in late March 2020.
“A few years ago, we were asked whether our next-gen squad weapon should have a muzzle brake or a suppressor,” Oberlin said in an interview with TechLink. “We asked ourselves ‘why not both?'”
Like any small-caliber muzzle brake, this new device vents the pressurized gas of each shot to counteract the recoil of the rifle. By venting the gas through a series of tiny asymmetric holes, the device has — in testing thus far — reduced volume by 50 percent and flash signature by 25 percent with minimal weight increase (0.8-3.0 pounds). “Suppressors are notorious for increasing flash,” Cler said. Furthermore, the Smuzzle adds only three inches to the weapon’s overall length.
When a weapon is fired using a suppressor, gases are trapped inside from the sound rings from the front of the suppressor back to the breech. That spreads the carbon throughout the weapon. It can force the soldier to clean the weapon more frequently.
“That brake baffle actually has a curvature to it borrowed from a 155mm muzzle brake I designed,” Cler said. But the researchers have stated that the device is scalable to any caliber.
“It was designed for automatic and semi-automatic weapons, but it’d be useful for anyone shooting magnum cartridges,” Cler said. “It has what you could call a bottom blocker that also reduces how much dust kicks up.” A smaller Smuzzle weighing 0.8 lbs and other larger versions weighing approximately 3 lbs have been developed to be used depending on a weapon’s caliber.
Binter said in a piece with the Army Times that although they have not yet tested the prototype devices to failure, nevertheless some of them had already fired 10,000 rounds through the weapons which continue to hold up to the sound, recoil, and accuracy standards.
In one test the researchers fired hundreds of rounds through one prototype Smuzzle attached to an M240B machine gun in a full auto failure test. (See video below.)
“It was glowing red, but it never failed,” Cler said.
In testing the weapon is expected to be able to sustain a rate of fire of 600 rounds per minute.

The silk spiders produce is tougher than Kevlar and more flexible than nylon, and Air Force researchers think it could be key to creating new materials that take the load and heat off troops in the field.
Scientists at the Air Force Research Lab and Purdue University have been examining natural silk to get a sense of its ability to regulate temperature — silk can drop 10 to 15 degrees Fahrenheit through passive, radiative cooling, which means radiating more heat than it absorbs, according to an Air Force news release.

Those researchers want to apply that property to synthetics, like artificial spider silk, which is stronger than Kevlar, the polymer typically used in body armor, and more flexible than nylon.
Enhancing body armor and adding comfort for troops is one of many improvements hoped for by a team led by Dr. Augustine Urbas, a researcher in the Functional Materials Division of the Materials and Manufacturing Directorate.
“Understanding natural silk will enable us to engineer multifunctional fibers with exponential possibilities. The ultra-strong fibers outperform the mechanical characteristics of many synthetic materials as well as steel,” Urbas said in the release. “These materials could be the future in comfort and strength in body armor and parachute material for the warfighter.”
In addition to making flexible, cooler body armor, the material could also be used to make tents that keep occupants cooler as well as parachutes that can carry heavier loads.
Artificial spider silk may initially cost double what Kevlar does, but its light weight, strength, flexibility, and potential for other uses make it more appealing, according to the release.
Air Force researchers are also looking at Fibroin, a silk protein produced by silkworms, to create materials that can reflect, absorb, focus, or split light under different circumstances.
It’s not the military’s first attempt to shake up its body armor with natural or synthetic substances.

Two years ago, the Army said it was looking into using genetically modified silkworms to create a tough, elastic fiber known as Dragon Silk.
Dr. James Zheng, chief scientist for project manager Soldier Protection and Individual Equipment, told Army Times at the time that while the Army is developing and testing material solutions all the time, “Mother Nature has created and optimized many extraordinary materials.”
At the end of 2016, then-Air Force Academy cadet Hayley Weir and her adviser, professor Ryan Burke, successfully tested a kind of viscous substance that could be used to enhance existing body armor. Weir did not reveal the formula for the substance, but she used plastic utensils and a KitchenAid mixer to whip up the gravy-like goo, placing it in vacuum-sealed bags and flattened into quarter-inch layers.
The material was designed to be lighter than standard Kevlar and offer more flexibility for the wearer. During tests, when struck by bullets, the gooey material absorbed the impact and stopped the bullets.
