Russia showed off its new “Star Wars-like” combat suit on Thursday at a science and technology university in Moscow, state-owned media outlet RT reported.
The “next-generation” suit comes with a “powered exoskeleton” that supposedly gives the soldier more strength and stamina, along with “cutting-edge” body armor, and a helmet and visor that shields the soldier’s entire face, RT said.
The suit also has a “pop-up display that can be used for tasks like examining a plan of the battlefield,” Andy Lynch, who works for a military company called Odin Systems, told MailOnline. There’s also a light on the side of the helmet for inspecting maps or weapons.
Russia hopes to produce the suit “within the next couple of years,” Oleg Chikarev, deputy chief of weapons systems at the Central Research Institute for Precision Machine Building, which developed the gear, told MailOnline.
It should be noted, however, the video only showed a static display of the suit, and it’s still an open question of whether it actually has any of the capabilities that are claimed.
Still, Russia is not the only country developing such technology, Sim Tack, a Stratfor analyst, told Business Insider in an emailed statement.
The US hopes to unveil its own Tactical Light Operator Suit, also known as the “Iron Man” suit, in 2018.
Tack said that France is perhaps furthest along in creating its Integrated infantryman equipment and communications system, or FELIN, but it’s not as high-tech as the Iron Man suit.
Nevertheless, it’s “unclear whether these type of suits will eventually make it to the battlefield,” Tack said.
Some technical problems still persist: for example, the batteries required to power the exoskeletons — many of which have leg braces that evenly distributes weight and allows the soldier to run faster and jump higher — are too bulky because the suits require so much power, Tack said.
But given how much effort countries are putting into developing these suits, “we may well see some type of them reach the battlefield at some point,” Tack said.
“Patton’s Panthers” was one of the most effective tank battalions in World War II, fighting a continuous 183 days at the front and inflicting heavy casualties on the Germans while crews racked up accolades from their peers, including three Medal of Honor nominations in their first month of combat.
The first black armored unit was the 758th Tank Battalion which received 98 black enlisted men in 1941. The 761st followed in March 1942 as a light tank battalion but converted to medium tanks in September 1943.
It was on that day that the battalion struck a German roadblock that could spell doom. The tanks were forced to stop, making them easy targets for German guns.
Despite fierce German fire, Staff Sgt. Ruben Rivers rushed out of his tank and attached a cable to the roadblock before dragging it out of the way. The American tanks pushed forward through the opening and the attack was successful.
The next day, Charlie Company 1st Sgt. Samuel Turley found his company under heavy German fire with wrecked tanks. He ordered the crews to dismount and organized a resistance before climbing from a ditch to lay down cover fire. His gamble saved his men, but he was cut down by German machine gun fire.
The day after that, on Nov. 10, Sgt. Warren G.H. Crecy fought his way forward to save his men under fire until his tank was destroyed. He then commandeered another vehicle and killed his attackers with a .30-caliber machine gun before turning the weapon on German artillery observers.
On Nov. 11, Crecy was back at it. His tank was immobilized and he attempted to get it going until he saw German units attacking the nearby infantry. So he climbed onto his .50-cal. and gave them cover. Later that day, he destroyed machine gun nests and an anti-tank weapon.
Rivers was back in the spotlight Nov. 16-19. A mine shot fragments through his leg and destroyed his knee on Nov. 16. Despite the recommendation that he immediately evacuate, Rivers led the way across a brand-new bridge the next day and took on four German tanks, killing two and driving two more back.
By Nov. 18, Rivers’ leg was infected but he still refused to go home. The next day, Rivers directed fierce fire onto German anti-tank guns until two rounds pierced his own tank and went through his head, killing him instantly.
All three men, Rivers, Crecy, and Turley, were nominated for the Medal of Honor but only Rivers received it.
The next month the 761st conducted assaults aimed at breaking up the German forces at the Battle of the Bulge, slowing German resupply and taking the pressure off the units under siege despite the fact that the 761st was fighting a numerically superior enemy.
After another month and a half of fighting, the 761st threw itself against a dug in and numerically superior enemy once again while leading the armored spearhead through the Siegfried Line and fought “the fiercest of enemy resistance in the most heavily defended area of the war theater” for 72 hours according to its Presidential Unit Citation.
On May 5, 1945, the 761st linked up with Russian Forces in Steyr, Austria. Over the course of the war, the unit had lost nearly 50 percent of its starting forces and 71 tanks. It was also credited with inflicting 130,000 casualties.
The latest venture north began Tuesday, when Navy and Coast Guard ships joined Canadian, Danish, and French vessels for the annual Canadian-led exercise Operation Nanook in the waters between Canada and Greenland.
The exercise consists of “basic tactical operating in the higher latitudes,” elements of which are “significantly different than how we operate” elsewhere, Lewis said.

“If you fall in the water where they’re going to be operating, you’re not going to survive very long unless you have the proper equipment on board, which is something that we have taken off our ships in recent years, and now we’ve put it back in,” Lewis said.
“You have to have the flexibility and the timing built into your scheme of maneuver … because the weather has a huge impact on your ability to make it through straits or going through a certain chokepoint,” Lewis said.
US Navy guided-missile destroyer USS Thomas Hudner will also do rigid-hull inflatable boat operations as part of the exercise. “It is the first time that we’re putting a boat in the water recently in these temperature climates,” Lewis said.

“It’s by nature a fairly challenging environment anyway,” Lewis added. “But then you throw the temperature and the potential sea state being higher — that’s something we need to kind of take a crawl-walk-run approach to.”
Nanook will have gunnery and other drills, such as tracking vessels of interest. “A lot of it has to do with basic warfare serials … and then basic security tasks and operating together,” Rear Adm. Brian Santarpia said Tuesday.
Santarpia, who commands Canadian naval forces in the Atlantic and Arctic, said it was “great” to get sailors into unfamiliar surroundings.
“Once we put them up there, they’re going to solve all the problems on their own,” Santarpia said. “They just have to recognize that there is a challenge and then they tend to get after it.”

‘We’re going to learn a lot’
The Canadian military has conducted Operation Nanook since 2007, working with local and foreign partners to practice disaster response and maritime security across northern Canada. There will be no operations ashore this year because of COVID-19.
The Canadian ships left Halifax on Tuesday with US Coast Guard medium-endurance cutter Tahoma. They will meet USS Thomas Hudner and sail north to meet French and Danish ships and operate around the Davis Strait, off Greenland’s west coast.
“This will be the farthest north that we have deployed this class of cutter, so we’re excited to showcase the agility of our fleet,” Vice Adm. Steven Poulin, the Coast Guard’s Atlantic Area commander, said Tuesday.
“That’s one of the reasons we wanted to push this medium endurance cutter so far north. We’re going to learn a lot about our own operations” and about “the logistics chain that’s required to support our Coast Guard assets that are so far north,” Poulin said.

The Canadian military adjusted Nanook in 2018 to include “everything we did in the Arctic,” Santarpia said. “It demonstrates … to anybody who is interested in the Arctic that Canada knows … how to take care of its own security and sovereignty in that area.”
Santarpia said more activity in the Arctic, facilitated by a warming climate, underscores the need to be present there for strategic reasons as well as emergency response.
“Last year was the warmest year in the Arctic that they’ve ever had. This year’s on pace to be warmer yet. It allows us to operate [there] for a little bit longer,” Santarpia said, adding that Canada’s navy didn’t “have any [Arctic] ability until just Friday, when the very first Canadian Arctic offshore patrol ship was delivered.”
That ship, HMCS Harry DeWolf, arrived two years late, but five more are to be delivered to Canada’s navy and two to its coast guard in the coming years.
“Next year, it’ll be part of the of the exercise, and that vessel can operate actually in the first-year ice that’s a meter thick,” Santarpia said. But until then the Canadian navy “is limited to where the ice is not pack ice.”
As those waters become navigable for longer periods, “we will slowly be able to spend more time in the north,” Santarpia added. “As the new capability comes online … we’ll be up there for the majority of year eventually.”
Breakthrough research from the University of California-San Diego could take the US military one step closer towards having cloaked aircraft and drones.
Researchers Li Yi Hsu, Thomas Lepetit, and Boubacar Kante havesucceeded in creating an ultra thin “dielectric metasurface cloak,” which is composed of a multitude of ceramic cylinders embedded into a layer of Teflon.
Like an invisibility cloak, this coating could mask objects from visible light and radio wavelengths, the Army Times notes, and the military is paying attention.
“I am very excited about this work,” Kante told the Army Times.
The cloak functions by either absorbing or directing electromagnetic waves away from an object. This, in turn, effectively masks the object making it ‘invisible.’ While experiments in 2006 first showcased a limited degree of invisibility cloaking, the new breakthrough has two main advantages over older methods.
First, Kante told the Army Times, the new material his team discovered uses ceramics rather than metal particles making the material easier and cheaper to manufacture. Second, the method of using ceramics and Teflon allows the cloak to be effective with coating layers as thin as millimeters.
“Previous cloaking studies needed many layers of materials to hide an object, the cloak ended up being much thicker than the size of the object being covered,” Hsu said in a statement. “In this study, we show that we can use a thin single-layer sheet for cloaking.”
These advantages make a world of difference in real world applications, which is why the military has taken a keen interest in the new cloak. Whereas older cloaking technology would have required 30cm of Teflon coating to mask a Predator drone from a surveillance system, the new cloaking technology could hide the same drone from the same radar with only 3mm of coating, the Washington Post reports.
This suddenly takes the idea of cloaking away from the realm of sci-fi and moves it firmly towards real world applications. Kayla Matola, a research analyst with the Homeland Defense and Security Information Analysis Center, told the Army Times that the new cloaking technology is “basically what the military’s looking for.”
“If anything this could provide the military with air superiority,” Matola told the Army Times.
And although the technology is still in its nascent stages, Matola estimates that due to the ease of manufacturing the coating from ceramics and Teflon, full scale production and utilization of the technology could occur within the next decade.
“There’s no fundamental roadblocks,” Kante told the Army Times. “It would be easy to manufacture.”
However, despite Matola’s optimism, there are still fundamental issues associated with the technology. The cloak can only be used to block one potential wavelength at a time currently, Endgadget reports, drastically limiting the current applicability of the current cloak.
Additionally, the cloak only blocks wavelengths that hit the target within a six degree range of a 45 degree angle. Beyond that range any item covered in the cloak would still be fully visible. The researchers said they are working on widening the range.
The US Air Force is now accelerating a massive AI push to cyber-harden networks, improve weapons systems, and transform functions of large combat air platforms such as the B-2, F-15 and F-35, service officials said.
“The Air Force has over 600 projects incorporating a facet of artificial intelligence to address various mission sets,” Capt. Hope Cronin, Air Force spokeswoman, told Warrior Maven.
While AI can of course massively expedite data consolidation, cloud migration and various kinds much-needed cybersecurity functions, it is increasingly being applied more broadly across weapons systems and large platforms.
AI performs a wide range of functions not purely restricted to conventional notions of IT or cyberspace; computer algorithms are increasingly able to almost instantaneously access vast pools of data, compare and organize information and perform automated procedural and analytical functions for human decision-makers in a role of command and control.
When high-volume, redundant tasks are performed through computer automation, humans are freed up to expend energy pursuing a wider range of interpretive or conceptual work.
For the F-35, B-2 and F-15, rapid data-base access, organizing information and performing high-volume procedural functions are all decided advantages of AI applications. Algorithms, for example, are increasingly able to scan, view and organize targeting, ISR and sensor input such as navigation information, radar warning information, images or video.

The F-35, for instance, uses early iterations of artificial intelligence to help acquire, organize and present information to the pilot on a single screen without much human intervention. Often referred to as easing the cognitive burden upon pilots, the effort is geared toward systematically presenting information from a range of disparate sensors on a single screen. The F-35s widely-discussed sensor fusion, for example, is evidence of this phenomenon, as it involves consolidating targeting, navigation and sensor information for pilots.
An F-35 computer system, Autonomic Logistics Information System, involves early applications of artificial intelligence wherein computers make assessments, go through checklists, organize information and make some decisions by themselves — without needing human intervention.
The computer, called ALIS, makes the aircraft’s logistics tail more automated and is able to radio back information about engine healh or other avionics.
A single, secure information environment provides users with up-to-date information on any of these areas using web-enabled applications on a distributed network, a statement from ALIS- builder Lockheed Martin says.
ALIS serves as the information infrastructure for the F-35, transmitting aircraft health and maintenance action information to the appropriate users on a globally-distributed network to technicians worldwide, the statement continues.
As a result, F-35 pilots will be able to control a small group of drones flying nearby from the aircraft cockpit in the air, performing sensing, reconnaissance and targeting functions.
At the moment, the flight path, sensor payload and weapons disposal of airborne drones such as Air Force Predators and Reapers are coordinated from ground control stations.
For instance, real-time video feeds from the electro-optical/infrared sensors on board an Air Force Predator, Reaper or Global Hawk drone could go directly into an F-35 cockpit, without needing to go to a ground control station. This could speed up targeting and tactical input from drones on reconnaissance missions in the vicinity of where a fighter pilot might want to attack. In fast-moving combat circumstances involving both air-to-air and air-to-ground threats, increased speed could make a large difference.
The prospect of using advanced algorithms and on-board computers to quickly perform a range of aircraft functions, while enabling human decision makers in a role of command and control, is further explored in a research paper from a London-based think tank called “Chatam House – Royal Institute of International Affairs.”
The 2017 essay, titled “Artificial Intelligence and the Future of Warfare,” explains how fighter and bomber pilot “checklists” can be enabled by AI as “cognitive-aiding tools.”
“…pilots rely significantly on procedures to help them manage the complexity of various tasks. For instance, when a fire-light illuminates or another subsystem indicates a problem, pilots are trained to first stabilize the aircraft (a skill) but then turn to the manual to determine the correct procedure (rule following). Such codified procedures are necessary since there are far too many solutions to possible problems to be remembered,” the Chatam House paper writes.
The Air Force’s stealthy B-2 bomber is yet another example; the aircraft is receiving a new flight management control processor which increases the performance of the avionics and on-board computer systems by about 1,000-times, Air Force officials said.
The upgrade is a quantum improvement over the legacy system, providing over a thousand times the processor throughput, memory, and network speed, according to senior Air Force leaders. The new processor will help automated navigation programs and expedite the B-2s “fly-by-wire” technology — all of which are designed to enable a pilot to expend energy upon the most pressing combat tasks with less intervention.

The B-2 Flight Management Control Processor Upgrade, also known as the Extremely High Frequency, Increment 1 processor upgrade, completed the final aircraft install in August 2016, Air Force officials told Warrior Maven in 2017.
Faster, more capable processors will enable the aircraft’s avionics, radar, sensors, and communications technologies to better identify and attack enemy targets. The sensor-to-shooter time will be greatly reduced, allowing the B-2 to launch weapons much more effectively, therefore reducing its exposure to enemy attacks.
Although built in the 1980s, the B-2 is a digital airplane which uses what’s called a “glass cockpit” for flight controls and on-board systems.
The upgrade involves the re-hosting of the flight management control processors, the brains of the airplane, onto much more capable integrated processing units. This results in the laying-in of some new fiber optic cable as opposed to the mix bus cable being used right now — because the B-2’s computers from the 80s are getting maxed out and overloaded with data, Air Force officials told Warrior.
Improved Processing capacity for the B-2 will enable the upcoming integration of digital nuclear weapons, such as the B61-12, service officials explained.
Also, the Air Force F-15 is now being engineered with the fastest jet-computer processor in the world, called the Advanced Display Core Processor, or ADCPII.
“It is capable of processing 87 billion instructions per second of computing throughput, translating into faster and more reliable mission processing capability for an aircrew,” Boeing spokesman Randy Jackson told Warrior in 2017.

A new poll from the University of Maryland indicates that the majority of Americans favor of cutting funding from the U.S. defense budget in five out of seven major areas.
Specifically, they favor defunding one of the U.S.’ 11 aircraft carriers, and the F-35 Lightning II, DefenseNews.com reports.
“Given all the talk about increasing the defense budget, we were surprised to find how much Americans are not sold on increases, including a majority of Republicans nationwide,” said Steven Kull, director of the University of Maryland’s Program for Public Consultation.
Indeed the survey, which polled more than 7,000 U.S. voters across the nation, shows that a majority of Republicans would prefer to keep defense spending where it is, a majority of Independents favor reducing the defense budget by $20 billion, and Democrats favor slashing the budget by $36 billion.
The survey presented 2015 figures on spending and offered alternatives. For example, when informed that cutting funding to the F-35 program would save $6 billion this year, and $97 billion through 2037, 54 percent of citizens polled supported cutting the program.
Though the desire to save money and be fiscally responsible is admirable and understandable, top brass in nearly all U.S. military services have expressed concern that nations like Russia and China threaten the U.S.’ foreign interests, and some have even gone as far as to call them existential threats.
On Tuesday, top Air Force acquisitions personnel took to Congress and re-asserted the need for the U.S.’ fifth generation fighter planes. “We’ve seen both Russia and China develop airplanes faster than was anticipated,” said Lt. Gen. James “Mike” Holmes, according to the Air Force Times.
The survey suggested that Americans supported cutting the number of U.S. aircraft carriers to 10 from 11.
Surprisingly, nationally, the majority of Americans did not support shrinking the submarine fleet from 12 to eight, nor did they want to cut funding to development of a new long range strike bomber.
For anyone who’s been through it, recruit training (or boot camp or whatever your service calls it) conjures up memories of hard work, new life lessons and a real sense of accomplishment.
But while the reward at the end of the experience seems worth it when it’s over, a lot of boot camp just plain sucks.
So here are eight things you surely don’t miss about basic training.
1. Losing sleep
The days of sleeping until noon are over. Getting up at 0400 or 0500 every morning is the norm. At times, trainees only get four hours of sleep due to night training events. Eventually, recruits learn to take “power naps” during moments of downtime to make up for the lack of sleep.
2. Eating in a hurry
During basic training, you have mere minutes to eat your food. This is where the old saying of “eat your chow in a hurry, you’ll taste it later” earns its meaning.
3. Fire Guard
You are sleeping comfortably following a long day of training when suddenly a fellow trainee wakes you up and tells you “it’s your turn for fire guard.”
It’s 0200, you walk around the barracks or sit at a desk while making sure the doors are secure and everyone is accounted for is part of military conditioning during training.
On fire guard, you must also be alert because drill sergeants could show up at any time to make sure guards are not sleeping on duty. They may even ask you some military questions or ask you to recite your general orders.
4. Running everywhere
Some days you may have felt like Forrest Gump because at boot camp you “just kept running” everywhere you went. “Double time” is a way of life.
5. Buffing floors
It feels like trainees should earn a special badge for the number of times they buff the floors during basic training. The sad part is those floors only stay clean for about a half day.
6. Doing push-ups
Doing hundreds of push-ups every day will make you stronger. However, at some point your arms will feel like they are going to fall off.
7. The gas chamber
I don’t think anyone misses the feeling of choking, thinking your eyes are coming out of their sockets and mucus flowing out of your nose.
8. Getting yelled at all day long
After finishing boot camp, you’ll appreciate having a conversation with someone who isn’t 1 inch from your face and screaming in your ear.
Tell us what you don’t miss from basic training/boot camp in the comments section below.
War heroes can emerge from plenty of unexpected places, and that includes kennels, lofts, and stables. Here are seven awesome war heroes who didn’t let being an animal get in the way of winning human conflicts.
1. The pigeon who saved 194 American lives after being shot through the chest.
Cher Ami was a messaging pigeon serving in the Argonne Forest with the 77th Infantry Division when the battalion of 550 soldiers she was with was completely cut off by German forces. After four days of heavy fighting, friendly artillery decided the battalion must have surrendered already and began firing on the 77th.
In 1917, Stubby joined a group of American soldiers training for the trenches of World War I. He deployed with the men overseas and proved himself in battle multiple times, waking soldiers as he sensed incoming artillery attacks and infantry assaults that human sentries hadn’t yet detected.
Despite being caught in multiple gas attacks, Sgt. Stubby survived the war and the supreme commander of American Forces in World War I, Gen. John Pershing, personally awarded him a gold medal in 1921 for his efforts.
Wojtek the bear was bought and adopted by Polish soldiers making their way back east after they were released from a prison camp in Siberia in 1942.
4. The horse that ferried ammunition and wounded Marines despite two wounds from enemy fire.
Sgt. Reckless was a Marine in an anti-rifle platoon during the Korean War. She served in a few battles as an ammo carrier and evacuated wounded troops when necessary. In the Battle of Vegas in early 1953, Reckless carried rounds for three days straight.
5. Simon continues catching rats during a siege after nearly dying of injuries from artillery fire.
In April 1949, the HMS Amethyst was ordered up the Yangtse to guard the British embassy in Nanking during the war between Communists and Nationalists in China. As the Amethyst moved up the river, it came under heavy fire from a Communist shore battery and ran aground.
Besieged by Communist forces, the Amethyst was trapped for a total of 101 days. The ship’s cat, Simon, was riddled by shrapnel and partially burnt by artillery fire in the initial attack but forced himself back into service to combat a surge of rats that were damaging the limited rations in the ship. His efforts allowed the men to just barely survive the siege as rations nearly ran out. He was the first member of the Royal Navy to receive the Dickin Medal for animal valor.
7. Nemo the dog fights off attackers after being blinded.
Nemo and his handler, Airman 2nd Class Bob Thorneburg, were patrolling a cemetery near their base in Vietnam on Dec. 4, 1966 when they were attacked by the Viet Cong. Nemo was shot in the eye while Throneburg took a round to the shoulder.
America has fought in a lot of wars so it can be hard to keep track of all of them. As a quick reference guide, here is every American war, each captured in a single tidy sentence.
American Revolution: The Colonials hated King George and his taxes on tea and so fought to be ruled by President George instead.
Whiskey Rebellion: Americans hated President George and his taxes on whiskey, but Washington won a bloodless victory and kept his tax.
Quasi-War: America didn’t want to pay debts owed to France, so France started stealing ships, America recreated its Navy, and everybody fought until they realized the war was costing everyone more money than anyone was making in profit.
Barbary Wars: Americans fought two wars to navigate the waters north of Africa freely, losing the first and winning the second.
War of 1812: Mad about the British restricting American trade and capturing U.S. sailors, America declared war, lost much of her merchant fleet, watched the White House burn down, and then got what they wanted in the peace treaty anyway.
Mexican-American War: President Polk wanted to double the size of the country, so he picked a fight with Mexico and captured land from Texas to the Pacific.
Utah War: The Army made a show of force, the Mormons massacred a bunch of people, and everyone agreed to replace the Mormon Utah governor with a non-Mormon and forget the whole thing.
Indian Wars: The Native Americans owned land the settlers wanted so brief skirmishes led to full wars where Federal troops used biological warfare and everything ended badly for the Native Americans.
Civil War: The South wanted to keep their slaves and the North wanted to send them to Africa, so everyone fought a war and the South lost.
Spanish-American War: A battleship blew up in Havana and a pissed off America invaded Spanish territory in Cuba and won itself a small overseas empire.
Philippine-American War: The Philippines were violently opposed to becoming an American territory, so America killed the Filipinos until they changed their mind.
Border War: A Mexican revolution kept spilling over into America, so Gen. Pershing chased Pancho Villa and the U.S. garrisoned troops along the border.
Banana Wars: American fruit producers supported insurrections throughout Central and South America and U.S. troops backed them up when necessary to protect business interests.
World War I: After European nations fought each other for three years, America showed up, killed the survivors, and declared itself the champion of the world.
World War II: The Allies used American manufacturing, British technology, and Russian numbers to defeat the fascists and America began the Nuclear Age by obliterating two cities with atomic bombs.
Korean War: A communist government backed by the Soviet Union and China fought a democratic government backed by the U.S. and others in clashes up and down the peninsula for over three years before settling on a border in roughly the same spot as when the war began.
Dominican Civil War: America participated in another country’s civil war off and on for nearly 50 years.
Vietnam War: An armed resistance to French rule turned into a proxy war of America vs. China and Russia that some Americans still don’t admit they lost despite Vietnam now being a single communist state.
Grenada: America jumped into another country’s civil war and declared itself the winner, maybe or maybe not saving the lives of some American medical students studying there.
Panama: Panama’s civil war threatened American forces and the Panama canal, so after a Marine lieutenant was killed America invaded, dismantled the ruling government, and captured the dictator in under three weeks.
Gulf War: An anti-American, oil-rich dictator invaded the land of a Pro-American, oil-rich monarch, so America led a massive air assault followed by a ground invasion that destroyed the world’s fourth largest army in 100 hours.
Somali Civil War: America joined a peacekeeping force to try to curb clan warfare but left amid mounting casualties.
Bosnian Civil War: America joined a peacekeeping force that successfully curbed ethnic fighting in the Republic of Bosnia and Herzegovina.
Kosovo War: America joins an ultimately successful peacekeeping effort aimed at reducing ethnic fighting in Kosovo and demilitarizing a terrorist group in the country.
War on Terror: After suffering the worst single terror attack in history, America declared war on terrorism and has been fighting ever since, most prominently in Iraq and Afghanistan but also in smaller conflicts throughout Africa, the Middle East, and southern Asia.
Admittedly, I’d rather not be shot with either, but if I had to choose, I’d take a round from the AK47 over the M4 any day of the week. To understand why, it’s important to have a very basic look at the physics behind terminal ballistics, in this case being the science of what happens when a penetrating missile enters a human body. The first place to start is the Kinetic Energy Equation:
KE = ½ M (V12 – V22)
Breaking this equation down into its components, we have Kinetic Energy (KE) influenced by the Mass (M) of the penetrating missile, as well as the Velocity (V) of the missile. This make sense, and it is logical that a heavier, faster missile is going to do more damage than a lighter, slower missile. What is important to understand is the relative influence that Mass and Velocity have on Kinetic Energy, as this is key to understanding why I’d rather be shot by an AK than an M4.
You’ll notice that the Mass component of the KE equation is halved, whereas the Velocity component is squared.
For this reason, it is the Velocity of the projectile that has far more bearing on the energy that it dissipates into the target than the mass.
The V1-V2 component of the equation takes into consideration that the projectile might actually pass straight through the target, rather than coming to rest in the target. In this instance, the change in the Velocity of the projectile as it passes through the target (V1 being its velocity as it enters, and V2 being velocity on exit) is the factor that is considered when calculating how much energy the missile delivered into the target.
Naturally if the projectile comes to rest in the target (ie: no exit wound) then V2 equals zero and the projectile’s velocity as it entered (V1) is used to calculate the KE.
That’s enough physics for now, but you get the concept that the optimum projectile to shoot someone with is one that has a decent mass, is very, very fast, and is guaranteed to come to rest in your target, as to dissipate as much energy as possible into them, and hence do maximal damage.
The next concept to grasp is that of permanent cavitation versus temporary cavitation. Permanent cavitation is the hole that gets left in a target from a projectile punching through it. You can think of it simply like a sharp stick being pushed through a target and leaving a hole the diameter of the stick. The permanent cavity left by a bullet is proportionate to the surface area of the bullet as it passes through the tissue.
For instance, if an AK47 round of 7.62mm diameter at its widest point passes cleanly through a target, it will leave a round 7.62mm hole (permanent cavity). If this hole goes through a vital structure in the body, then the wound can be fatal. However, if the bullet passes through soft tissues only, then the permanent cavity can be relatively benign.
This is a slight oversimplification of the concept, as bullets will rarely remain dead straight as they pass through human bodies, as they have a tendency to destabilize, and the heavier back-end of the bullet will want to overtake the front.
This concept, known as yaw, increases the frontal surface area of the bullet as it passes through tissue, and hence creates a larger permanent cavity.
Far more damaging than the permanent cavity left by a projectile is the temporary cavity that it creates. Anyone who has ever watched the TV show MythBusters will have some familiarity with this concept, and it is best demonstrated using slow motion video imagery of bullets being shot into special jelly known as ballistic gelatin, which is calibrated to be the same density as human soft tissues.
What can be seen in these video images (below) is the pulsating dissipation of energy that emanates out from a bullet as it passes through the gelatin.
This is a visual illustration of the concept of temporary cavitation, and it allows the viewer to begin to appreciate the devastating effect that a high velocity missile can have once it enters a human body. The temporary cavitation is the transfer of Kinetic Energy from the projectile into the tissues of the target, and as we learned above, is relative to the mass and, more importantly, the velocity of the projectile.
As the energy of the projectile is dissipated into the tissues of the target the temporary cavitation pulverizes structures adjacent to the bullet’s tract, including blood vessels, nerves, muscles, and any solid organs that may be in close proximity.
For that reason the high velocity projectile does not need to pass directly through a structure in the body to destroy it. The higher the Kinetic Energy of the projectile the further out from the permanent cavity the temporary cavity extends.
Below is a slow motion video of a 5.56x45mm round (same as the M4 fires) hitting ballistic gelatine in slow motion. After watching, the medical provider can begin to appreciate the damage that gets done to tissues by the pressure wave of the temporary cavitation.
Another characteristic of the M4 round is the tendency for the bullet to disintegrate if it strikes tissue at a decent velocity. Despite being a jacketed round, owing to it being smaller, lighter, and faster than an AK47 projectile, it tends to yaw faster once it hits tissue and the shearing forces on the bullet once it is traveling at 90 degrees through the tissue often tears the bullet into pieces, thus creating multiple smaller projectiles and increasing the chances of all of the bullet parts remaining in the target, and hence dissipating more energy.
The AK47 round, being slightly heavier and slower than the M4 round will have a tendency to remain intact as it strikes tissue, and whilst it will penetrate deeper, it tends to remain intact and not yaw until it has penetrated much deeper than the M4.
The video below shows a soft point round being used, which theoretically should be more destructive than its full metal jacket counterpart, the video still illustrates nicely the significant penetration of the AK47 round without it yawing significantly or disintegrating.
I once saw a good case study illustrating this point nicely where a casualty had sustained an AK47 gunshot wound to the right lateral thigh and we recovered the intact bullet from the inside of his left upper abdominal wall. It had passed through approximately 1 metre of his tissues and shredded his small bowel, but the projectile hadn’t fragmented at all, and the temporary cavitation hadn’t done enough damage to be lethal. The casualty required a laparotomy to remove multiple sections of small intestine, but made a good recovery. That one is a story for another time.
Although an unpleasant injury to have, the fact that the AK47 round was travelling slower than an M4 at the same range would have been, coupled with the fact that the projectile remained intact and didn’t yaw significantly as in passed through him, meant the wound was nowhere near as devastating as the above-mentioned M4 injury in the same area.
It must be noted however that the comparison is far from perfect given that the M4 injury involved the bone, with the one immediately above passing solely through soft tissues.
So there it is, all things being equal, when all is said and done I’d rather be shot with an AK47 than an M4 on any day of the week. Naturally, as medical responders, it is always important to treat the wound and not the rifle that inflicted it, and I have certainly seen some horrendous AK47 wounds over the years and some relatively minor ones from M4s, so it all depends.
The main take home points for medicos are to be aware of the magnitude of damage that can be caused by the temporary cavitation resulting from high velocity missile wounds, and also if you find an entrance wound, there’s no telling where in the body the projectile might have ended up!
When one considers those pioneers whose command of air power strategy led to an independent U.S. Air Force after WWII, General Carl A. Spaatz is usually among those names. Spaatz would come to command the overall Army Air Forces in Europe, design the strategy for bringing down Hitler’s Luftwaffe, and cripple Nazi war production. Dwight Eisenhower as Supreme Allied Commander remarked Spaatz (along with Omar Bradley) was one of two men who contributed most to the victory in Europe.
So when it comes to how he views the people who serve in the military, you might be apt to consider his advice.
After V-E Day, Spaatz held a victory party at a chateau near Paris. The guest list included a who’s who of who would come to found the modern Air Force such as Hoyt Vandenberg and James Doolittle. It also included one Major: triple ace Robin Olds (pre-mustache). Spaatz was a friend of the Olds family, and he invited Robin to his party after he learned Maj. Olds would stay in the Army after the war.
Olds recounted the advice he received from Spaatz in his memoirs, Fighter Pilot, more than sixty years later:
” … In the military, they mostly divide themselves into four major categories. There are the ‘Me-Firsters,’ the ‘Me-Tooers,’ the ‘Deadwood,’ and the ‘Dedicated.’ You are among the minority, the Dedicated. Stick with them, search them out, and work hard to be worthy of their company. You won’t be popular with a lot of your bosses who act dedicated but really aren’t and that can make life difficult at times. Beware of the Deadwood. Most of them mean well and, in their own way, try hard, are loyal, and are even useful. But too often they’ll botch things up and get you and your outfit in trouble.”
“Watch out for the Me-Tooers. These guys will tell you whatever they think you want to hear. They borrow thoughts and ideas from others and present them to you as though they were their own. They are the opportunists who look for every avenue to advance themselves without sticking their own necks out. They ride someone’s coattails and try to make themselves indispensable to the boss. Believe me, they are not to be trusted. You don’t want yes-men around you, but you can’t always avoid them.”
Spaatz went on to warn: “The worst and most dangerous are the Me-Firsters. Most of them are intelligent and totally ruthless. They use the service for their own gain and will not hesitate to stick a knife in your back at the slightest indication you might stand in their way. They seem arrogant, but don’t be fooled. They are really completely lacking in true self-confidence.”
For all of you who still have the Internet, here are the 13 funniest military memes we could find. For those of you who have lost the Internet to Hurricane Matthew, get out there and get it back. You signed for that Internet.
1. He might not be able to find where he’s supposed to put it, but he will still definitely set it off (via Devil Dog Nation).
2. You must reach a perfect spiritual center before you are ready to eviscerate the enemy and leave their entrails hanging from trees (via Military Memes).
3. Travel all over the planet to find new and exciting decks to sweep (via Military Memes).
I know the sh*t has hit the proverbial fan and the world is going through a fairly sh*t time at the moment… But hold the presses because it came to light, via Business Insider, that Gen. James Mattis (Ret.) did some modelling work for a veteran-owned leather jacket company in between his time in the service to his appointment as Secretary of Defense.
Just when you thought the Patron Saint of Chaos could not get any more badass, he can apparently pull off a leather jacket far better than any of us ever could.
After reading that, I just don’t know what to do anymore. Anyway, here’s some memes while I contemplate whether dropping my stimulus check on that $1,300 jacket would be worth the ire of my wife…
