The group is passionate about supporting their own because after they came home from fighting a war their country sent them to fight, they were largely unsupported and even treated with hostility.
Vietnam vets don’t need to hear “thank you for your service” as much as, “welcome home.” So whether you know someone who served in southeast Asia or happen to pass one on your way to work, here are 9 actions you can take to give them the welcome home they never received:
1. Listen to them and learn their stories
Taking the time to learn and understand the experiences a veteran goes through helps you to understand them and appreciate their sacrifices on much more personal level.
2. Write them a letter
Giving a letter to a Vietnam veteran expressing your appreciation and support of what they sacrificed is something they can read on their own time and keep as a reminder that America ultimately cares about their era of service.
3. Give them a surprise welcome back
For extra effect, do this on the anniversary of the day they returned home from the war. Check around at local veteran organizations; you may be able to be part of a larger homecoming celebration, like the one in this video.
4. Perform community service together
Having an experience of serving together, no matter how small, is a shared experience you will both appreciate.
5. Organize a reunion for them
This may take a lot of planning, but coordinating an event that brings together Vietnam veterans who served together is going above and beyond showing how much you appreciate their service.
6. Organize their photos / records / awards into a scrapbook or shadowbox
Many vets have their memories in boxes or in storage somewhere. Ask to take them and display them so they will not be damaged but also displayed in an honorable way.
7. Give thanks by really helping them out
Ask if there is are any errands and chores you can do or to get to know them more, or see if there is anywhere you can go (museum, hike, etc.).
8. Have a memorial for the fallen
By visiting a memorial with them or having one of your own together, show them you honor the fallen and will never forget them.
9. Invite them to speak at a school class or social function
Having a veteran speak in a history class or at a social community event is a great way to educate the younger generation and your community about the services and sacrifices service members make.

Aircraft carriers are the cornerstone of America’s naval capabilities. They’re able to project air power anywhere in the world without having to depend on local bases.
And they are truly massive.
Spanning 1,092 feet long — three times the length of a football field — Nimitz-class warships like the USS George H.W. Bush are the largest aircraft carriers. See below for a selection of pictures showing how massive America’s aircraft carriers are:

Before the tank entered the lexicon of military history, there was horse cavalry.
The horse, like the modern day tank, provided support to the infantry and artillery. However, while every kingdom, like every modern nation today, has some sort of mobile land support designed to punch holes through enemy lines, only a handful of nations have the best trained. So here we take a look at 5 epic cavalry formations of the ancient world.
1. The Numidians (light cavalry)
The Numidians were from what is now Algeria and were known for their cavalry abilities.

Hannibal used these Numidian cavalrymen during the Second Punic War. So what made the Numidian cavalry so darn good?
The Numidians saw many battles during Hannibal’s campaign in Roman Italy. The Greek historian Polybius, describes the Numidian warriors as light cavalry armed with missile weapons (javelins). The Battle of Cannae 216 BCE, showcased their abilities.
What made the Numidian cavalry so effective at Cannae is that unlike the Spaniard and Celtic cavalries that also accompanied Hannibal, the Spaniard and Celtic horsemen were heavy cavalries that fought en masse, much like the Roman cavalry. The Numidians, being light cavalry, fought in a much looser formation and because of this, they harassed the Roman cavalry with complicated tactics before disengaging.
And while the Celtic and Spaniard cavalries had the Roman cavalry fixed, the Numidians went from harassment to providing shock support once the Roman cavalry turned their back. This caused the Roman cavalry to flee once the Numidians made contact and understood that if they do not make a break for it, they would be enveloped and decimated.
2. The Scythians (light cavalry)
The Scythians may not be the original inventors of asymmetrical warfare, but one could argue that they perfected it.

The Scythians were ancient nomadic horse warriors who were first mentioned by the Assyrians during the reign of Sargon II (reigned 722 – 705 BCE). What made these horsemen so powerful was that they were raised in the saddle and were typically armed with a distinctive composite bow.
The Scythian bow is unique and revered throughout the ancient world by kings, historians, and a philosopher. King Esarhaddon of Assyria had a Cimmerian bow, the Babylonian armies of Nebuchadnezzar II and Nabonidus were equipped with their bows and arrows, and even Hercules’ Greek portrait displays him armed with a Scythian bow. The Greek philosopher Plato said,
The customs of the Scythians proves our error; for they not only hold the bow from them with the left hand and draw the arrow to them with their right, but use either hand for both purposes.
When one examines the Scythian lifestyle, one can easily gain an understanding of the type of warfare necessarily carried on against more sedentary (non-migratory) people, like those in Mesopotamia. The Scythian took a guerilla approach to warfare as their method, using small bands to conduct military operations. Herodotus mentions their method of warfare when King Darius of Persia campaigned against them.
It is thus with me, Persian: I have never fled for fear of any man, nor do I now flee from you; this that I have done is no new thing or other than my practice in peace. But as to the reason why I do not straightway fight with you, this too I will tell you. For we Scythians have no towns or planted lands, that we might meet you the sooner in battle, fearing lest the one be taken or the other wasted. But if nothing will serve you but fighting straightway, we have the graves of our fathers; come, find these and essay to destroy them; then shall you know whether we will fight you for those graves or no. Till then we will not join battle unless we think it good.
The description indicates that the Scythians against whom Darius was warring had no center of gravity. King Darius’ military campaign into Scythia (modern Ukraine) went for nothing. As he could not catch them, the Scythians burnt their own their fields, destroyed Persian supplies, and harassed his forces with hit and run tactics.
In the end, Darius turned his large army around and headed home before it was annihilated.
3. The Parthians (light cavalry)
The Parthian horsemen are much like the Scythians.
The Parthians also known as the Parni/Aparni, originated from eastern Iran and like the Scythians, wore light attire, carried a composite bow and a sidearm — possibly a sword or a dagger. What made the Parthian horse archers so powerful was their ability to hit and run, and this was demonstrated at the Battle of Carrhae in 53 BCE between the Roman Republic and the Parthian Empire.

The Roman general Crassus led his Roman legions into the desert wilderness thinking they were going to face a pussycat. Instead, they found themselves face-to-face with an equal foe. Once Crassus gave the order to form a square, the Parthian horse archers saw an opportunity. They showered the Romans with raining death.
The average Parthian horse archer, with a quiver of 30 arrows, loosed between eight to ten arrows a minute at Carrhae. It would take almost three minutes to exhaust his arsenal before needing to be resupplied. The amount of Parthian horse archers at the battle is estimated at 10,000. Now, if all 10,000 fired away for 20 minutes, the amount of arrows fired by an individual horse archer would have been between 160-200 arrows. Take 10,000 and the amount of arrows fired upon the Roman soldiers are estimated to have been an astounding 1.6-2 million arrows in a 20-minute timeframe.
In the convulsion and agony of their pain they writhed as the arrows struck them; the men broke them off in their wounds and then lacerated and disfigured their own bodies by trying to tear out by main force the barbed arrow heads that had pierced through their veins and muscles.
Romans could do little, for if they break formation they are dead, if they stand still they are dead but have a chance. Only nightfall saved them. While the Parthian horse archers showered the Romans with death, the Parthian cataphract was the hammer.
4. The Parthian Cataphract (heavy armored cavalry)
When it comes to heavy cavalry in the ancient world, the Parthian cataphract takes the lead.

The word cataphract comes from the Greek Kataphraktos means “completely enclosed.” The origins of the cataphract may not have started with the Parthians but with the Massagetae, who also inhabited portions of Eastern Iran three centuries before the arrival of the Parthians. If you want more info on this, click “here.”
The Parthian cataphract in many ways looked like the medieval knights of Europe. What made them so effective on the field of battle was that the rider and horse were covered in armor. The rider would carry a lance, sword, and presumably a bow.
At the Battle of Carrhae, the cataphract would charge into Roman lines once the legions locked shields to protect themselves from the arrows. According to Plutarch, the cataphracts would hit the lines with such a force that “many (Romans) perished hemmed in by the horsemen. Others were knocked over by the pikes or were carried off transfixed.”
This hit and run attack would go on for some time until the Roman broke and fled.
5. Late Roman Equites Cataphractarii and Sassanid Clibanarii (very heavily armored cavalry)
It may be an understatement to say that Equites cataphractarii were heavy cavalry as they were indeed the heaviest of the bunch.
among them were the full-armoured cavalry (whom they called clibanarii or cataphracti equites), all masked, furnished with protecting breastplates and girt with iron belts, so that you might have supposed them statues polished by the hand of Praxiteles, not men. Thin circles of iron plates, fitted to the curves of their bodies, completely covered their limbs; so that whichever way they had to move their members, their garment fitted, so skilfully were the joinings made
The Clibanarii were Sassanid. However, the Sassanids also used this term to describe the Equites cataphractarii. The description provided by Ammianus Marcellinus about the Clibanarii goes as follows:
Moreover, all the companies were clad in iron, and all parts of their bodies were covered with thick plates, so fitted that the stiff joints conformed with those of their limbs; and the forms of human faces were so skilfully fitted to their heads, that, since their entire bodies were plated with metal, arrows that fell upon them could lodge only where they could see a little through tiny openings fitted to the circle of the eye, or where through the tips of their noses they were able to get a little breath. Of these some, who were armed with pikes, stood so motionless that you would think them held fast by clamps of bronze.
The Persians opposed us serried bands of mail-clad horsemen in such close order that the gleam of moving bodies covered with closely fitting plates of iron dazzled the eyes of those who looked upon them, while the whole throng of horses was protected by coverings of leather.
So who had the best cavalry in the ancient world? Well, the answer to that question is the various nomads who dotted the Eurasian Steppe, Central Asia, and the Iranian plateau. These various nomads are the ones who not only perfected horse archery and heavy cavalry, they also brought civilization the chariot.
However, horse archers and heavy cavalry — no matter the kingdom — would come to an end once the gunpowder age arrived. Eventually new tactics took the rider off his mount and placed him into a tank.
It seems like a country just can’t get world power status until they have an embassy overrun by locals in Tehran.
The United States Embassy in Iran was infamously overrun in 1979, with American hostages being held for 444 days. The last U.S. Ambassador to Iran, William H. Sullivan, was not among those hostages, and fortunately none of the American embassy workers were killed.
Probably less well-known is when the citizens of Tehran overran the Russian embassy in 1829. At the time, Iran was known as Persia and the two countries just concluded a two-year border war — which did not go well for the Persians.
Persia, especially the capital, was full of anti-Russian sentiment. The Persians had been forced to give up much of their northern border areas, lost access to the Caspian Sea, and most importantly (for these events) liberated any Armenian held captive to move to Russian territory.
The first official postwar Russian envoy to Persia was the renowned Russian comedy writer Alexander Griboyedov. The playwright and author recently married into Russian aristocracy, which resulted in his Persian posting.
Shortly after the Tsar sent Griboyedov to Tehran as Minister Plenipotentiary (a rank just below an official ambassador), two Christian Armenian women and one Armenian eunuch escaped from the Persian royal family harem, seeking refuge in the Russian embassy.
The Shah demanded their return, but Griboyedov wouldn’t give in. The terms of a treaty gave the Armenians the right to return to Russia. Thousands of angry Persians turned out to protest the Russian embassy, but Griboyedov wouldn’t budge.
The National Interest cited “contemporary accounts” in the telling of this story, saying the locals were incited by mullahs to storm the building. The Minister Plenipotentiary, other Russian diplomats, and the embassy guards in the building tried to fight as best they could but were overwhelmed.
Their bodies were dragged into the streets of Tehran, each decapitated in turn.
Griboyedov’s body was eventually returned to his native Tbilisi, now in Georgia. Shah Fath-Ali sent an envoy to Tsar Nicholas I of Russia as an apology for Griboyedov’s death, along with an 88-carat diamond, known as the Shah Diamond, in the hopes the Tsar wouldn’t return with the Russian army.
The diamond is still on display in the Kremlin, a grim reminder of how even the most powerful nations can still be victims of a mob.
Retirement planning can be stressful, but figuring out how to finance it takes a great deal of the stress away. Enter the government’s Thrift Savings Plan, or TSP. The first step in understanding TSPs is answering five basic questions: who, what, where, when, and why.
Who: The thrift savings plan is available to federal employees and members of the uniformed services. It is managed by BlackRock, a financial planning and investment firm headquartered in New York City.
What: TSP is a retirement savings plan similar to a private sector 401(k). Federal employees and military personnel can contribute up to a certain percentage of their base pay to their TSP. BlackRock assigns a broker to manage TSP accounts. Brokers are not held to the same standards as fiduciaries in that a broker has no vested interest in your funds; rather a broker’s only job is to invest money in suitable securities.
When: If you are a federal employee who joined your agency after 2010, you’re automatically enrolled in TSP with 3 percent of your base pay sent to your TSP; your agency matches this contribution automatically. If you joined your agency before 2010, an automatic 1 percent of your base pay is sent to TSP; your agency matches your additional contributions above the 1 percent. Military members must set up their own contributions and there is no matching contribution from the military.
Where: Military members can set up contributions to TSP through MyPay. Which type of funds you decide to invest in will determine when you can access the funds from that investment. There are L Funds, which are “lifestyle funds” that you can withdraw from at a predetermined time. Then there are G, F, S, C, and I funds, which rely on you to make your own investment decisions with a broker, according to the government’s TSP summary.
Why: A thrift savings plan gives you the ability to participate in a long-term retirement savings and investment plan. Additionally, you can choose between a regular TSP and a Roth TSP. Traditional TSP is tax free as you contribute, but you’ll pay taxes when you withdraw the funds. A Roth TSP allows you to pay taxes upon investment, and withdraw at a later date tax free. The upside to utilizing the government’s TSP is that you won’t pay fees to invest, and you’ll have a broker to manage the funds.
On May 2 and 4, 1972, two SR-71 Blackbirds overflew Hanoi, North Vietnam at noon. The first plane broke the sound barrier, causing an ear-splitting sonic boom over the city. Fifteen seconds later, the other Blackbird did the same thing.
Prisoners at Hoa Lo developed a code-tapping language to communicate with each other. Capt. James Stockdale, who was the senior ranking officer at the prison, taught many incoming POWs this code. It kept the men sane and their spirits up.
Communicating with Washington was trickier. Three months into his captivity, Stockdale was allowed to write to his wife, Sybil. Two months later, he was allowed to write again. When she received the letters, she found them confusing. Nicknames and references to their mutual friends were wrong.
Sybil gave the letters to Naval Intelligence in San Diego who figured out he was using doublespeak – deliberately misleading language –to let his superiors know he was not being treated well in North Vietnam. With her cooperation, the CIA and Office of Naval Intelligence decided to use her correspondence back to her husband as a way to communicate with the prisoners.
Her first letter included a Polaroid of her with a secret message sandwiched between the sheets of photographic paper. It explained the process of using invisible ink to send messages to the CIA. He listed the other POWs with him and detailed the abuses inflicted on American prisoners there.
The new communication policy allowed the prisoners and the CIA to trade a wealth of information, so much so that the prisoners were actually able to assemble a small shortwave radio, which was eventually discovered during an inspection).
In 1969, two prisoners, Air Force Captains John Dramesi and Edwin Atterberry, escaped from the prison at Cu Loc but were recaptured the next day. Massive reprisals from their captors followed, and thus the prisoners’ leadership determined the retribution was too much and escape attempts should only be made with a “high likelihood of success and assurance of outside assistance.” That’s when they came up with the Red River plan.
Members of the escaping POW group sent their plan to the U.S. Defense Secretary Melvin Laird approved the plan in January 1972. By May, everything was in place. The sonic booms were a go.
Despite a few setbacks, members of SEAL Team One and Underwater Demolition Team Eleven used SEAL Delivery Vehicles (SDV – mini-submarines) and HH-3A helicopters to patrol the coastline throughout May and June looking for escaped POWs. They never found any.
As the senior ranking officer, Stockdale forbid any escape attempts. He judged the plan too risky and the threat of reprisals too harsh. (Prisoners were often killed during these reprisals). The would-be escapees were frustrated by the policy, but they obeyed.
Article III of the Code of Conduct for prisoners does say American POWs should make every effort to escape captivity. Article IV, however, prohibits any action that would cause harm to other captured personnel. So Thunderhead was terminated.
The POWs would communicate with Washington throughout the war. Eventually, another radio was smuggled in, which gave POWs a direct line from the camp to the U.S. Seventh Fleet commanders aboard ships in the Gulf of Tonkin.
In January 1973, 591 POWs were repatriated back to the United States. For his leadership among the prisoners and work to galvanize the resistance to their captors, Stockdale received the Medal of Honor from President Gerald Ford.
Although the US Marine Corps may have unveiled their futuristic Multi-Utility Tactical Transport recently, another unlikely source may have beaten them in the race to develop an automated combat-centric vehicle.
According to the Baghdad Post and Defense One, two Iraqi brothers have developed a four-wheeled vehicle with a wide assortment of features for combat.
Called “Alrobot,” Arabic for robot, this laptop-controlled unmanned vehicle comes equipped with four cameras and is capable of remotely firing its mounted machine gun and Katyusha rockets. Having a range of around one kilometer, reports have also stated that this robot is slated to assist the Iraqi Security Forces with their fight against ISIS militants very soon.
With the ISF and coalition forces planning on beginning their assault on Mosul — Iraq’s second-largest city and one of the few remaining ISIS bastions — it might play an instrumental role in its liberation.
F-9 Cougar hitting the ramp of the USS Midway (CV 41) during the Korean War. For some reason that only Paramount Pictures might be able to explain, the film of this mishap was used to represent an F-14 Tomcat crashing in the movie “The Hunt for Red October.”
In the fall of 1989 I was a lieutenant in the Navy on a shore tour serving as the editor of Approach magazine, which is the Naval Safety Center’s aviation safety publication. Among my duties was to produce the “Crash n’ Bash” video — a collection of aircraft carrier mishap footage set to music — for use at the command’s booth during the annual Tailhook Convention in Las Vegas.
In the days before YouTube and Facebook this sort of video was very unique, and the Naval Safety Center’s booth was very popular as a result. Most people hadn’t seen this footage and setting the crashes to music was a brand new idea at the time.
Among those who saw the video was Paramount Studio’s production team working on the film “Hunt for Red October,” based on Tom Clancy’s wildly popular debut novel. A few weeks after I got back from the convention one of the producers called me and explained that he was working with the Navy’s public affairs reps and they had instructed him to call me to obtain the footage they’d seen at Tailhook. I asked him what sort of airplane they needed to show crashing. The producer said an F-14.
After verifying it was cool with my immediate superior, I FEDEX’d Paramount the master copy of the full video, which contained a bunch of crash footage of various airplanes, including some F-14s.
Fast forward a few months to me watching the movie in a theater in Virginia Beach and being very surprised with the following scene:
You can see they show an F-14 on the screen behind actor Fred Thompson (playing the fleet commander who figures out what to do with a determined Jack Ryan played by Alec Baldwin). But as the airplane gets closer it magically switches into a Korean War-era F-9 Panther that plows into the carrier’s ramp and then rolls down the deck. (The pilot in that mishap survived with nothing more than minor burns to his wrists, by the way. I met him at Tailhook.) For some reason the Paramount filmmakers also reversed the image, so not only is it the wrong airplane, it’s the wrong airplane backwards.
If you go to the 1:42 mark of this video you can see more of the F-9’s approach, ramp strike, and aftermath:
I still don’t know why they picked that footage of all the stuff they had at their disposal. Gotta love Hollywood, I guess . . .
UPDATE: Navy hospital shooting ruled false alarm, according to Capt. Curt Jones, commanding officer of Naval Base San Diego.
An active shooter was reported Tuesday at the Naval Medical Center San Diego, according to the center’s Facebook page.
The message advises occupants to “run hide or fight.” Non-emergency response personnel were asked to avoid the compound at 34800 Bob Wilson Drive. The center posted that the shooter was believed to be in Building 26.
According to intitial reports, three shots were heard in the basement of the building, which is a combination of a gym and barrack. There are no reports of injuries.
Fox 5 San Diego reports that three nearby schools are on lockdown.
The U.S. Navy could not immediately confirm the report.
The facility has a staff of more than 6,500 military and civilian personnel, and aims to provide medical care to military service members, their families, and those who served in the past, according to its website.
“We’re not taking any chances and are executing procedures we’ve been trained for in this kind of situation,” Naval Medical Center spokesman Mike Alvarez said.
In a tactical situation, the last thing a Soldier wants to do is give away his position to the enemy.
The ZH2 hydrogen fuel cell electric vehicle promises to provide that important element of stealth, said Kevin Centeck. team lead, Non-Primary Power Systems, U.S. Army Tank Automotive Research, Development and Engineering Center at the 2017 Washington Auto Show here Thursday.
The ZH2 is basically a modified Chevy Colorado, fitted with a hydrogen fuel cell and electric drive, he said. It was put together fairly quickly, from May to September, and will be tested by Soldiers in field conditions later this year.
Charley Freese, executive director of General Motor’s Global Fuel Cell Activities, explained the ZH2 is stealthy because its drive system does not produce smoke, noise, odor or thermal signature. GM developed the vehicle and the associated technologies.
The vehicle provides a number of other advantages for Soldiers:
The ZH2 produces high torque and comes equipped with 37-inch tires that enable it to negotiate rough and steep terrain.
The hydrogen fuel cell can produce two gallons per hour of potable water.
When the vehicle isn’t moving, it can generate 25 kilowatts of continuous power or 50 kW of peak power. There are 120 and 240-volt outlets located in the trunk.
The vehicle is equipped with a winch on the front bumper.
Dr. Paul D. Rogers, director of TARDEC, said the Army got a good deal in testing this vehicle, leveraging some $2.2 billion in GM research money spent in fuel cell research over the last several decades. The Army is always eager to leverage innovation in new technology, he added.
While GM developed the technology and produced the demonstrator, the Army’s role will be to test and evaluate the vehicle in real-world field conditions over the next near.
How it works
Electricity drives the vehicle, Centeck said. But the electricity doesn’t come from storage batteries like those found in electric cars today. Instead, the electricity is generated from highly compressed hydrogen that is stored in the vehicle by an electrochemical reaction.
As one of the two elements that make water (the other being oxygen), there’s plenty of hydrogen in the world. But hydrogen isn’t exactly free, Centeck pointed out. It takes a lot of electricity to separate the strong bond between hydrogen and oxygen.
That electricity could come from the grid or it could come from renewables like wind or solar, Centeck said.
Existing fuels like gasoline, propane, and natural gas can also be used to extract hydrogen, he said. The Army and GM are comparing the costs and benefits for each approach and haven’t yet settled on which approach to use.
Christopher Colquitt, GM’s project manager for the ZH2, said that the cost of producing hydrogen isn’t the only complicating factor; another is the lack of hydrogen fueling stations.
Most gas stations aren’t equipped with hydrogen pumps, Colquitt pointed out, but California and some other places in the world are in the process of building those fueling stations. For field testing purposes, the Army plans to store the hydrogen fuel in an ISO container.
Another cost involves the hydrogen fuel cell propulsion system itself. Fuel cell stacks under the hood convert hydrogen and air into useable electricity. They are composed of stacks of plates and membranes coated with platinum.
In the ZH2 demonstrator, there are about 80 grams of platinum, costing thousands of dollars, he said. But within the last few months, GM developers have managed to whittle that amount of platinum down to just 10 grams needed to produce a working vehicle, he said.
The modern-day gas and diesel combustion engine took a century to refine. Now, GM is attempting to do that similar refining with hydrogen fuel cells in just a matter of months, he said. It’s a huge undertaking.
By refining the design, Colquitt explained, he means lowering cost and providing durability, reliability and high performance. Refining doesn’t just mean using less platinum, he explained. A lot of other science went into the project, including the design of advanced pumps, sensors, compressors that work with the fuel cell technology.
Colquitt said the ZH2’s performance is impressive for such a rapidly-produced vehicle. For instance, the fuel cell produces 80 to 90 kilowatts of power and, when a buffer battery is added, nearly 130 kilowatts. The vehicle also instantly produces 236 foot-pounds of torque through the motor to the transfer case.
The range on one fill-up is about 150 miles, since this is a demonstrator, he said. If GM were actually fielding these vehicles, the range would be much greater.
Not ready for consumers
Colquitt said hydrogen fuel cell technology hasn’t yet yielded vehicles for consumers, but GM is working on doing just that in the near future, depending on a number of factors, mainly the availability of fueling stations.
The Army is no stranger to the technology, he said. GM’s Equinox vehicles, powered by hydrogen fuel cells, are being used on several installations. The difference is that the ZH2 is the first hydrogen fuel cell vehicle to go tactical, he said.
The value of having the Army test the vehicle is that it will be driven off-road aggressively by Soldiers, who will provide their unvarnished feedback, Colquitt said. Besides collecting subjective feedback from the Soldiers, he said, the vehicle contains data loggers that will yield objective data as well.
Testers will put the vehicle through its paces this year at Fort Bragg, North Carolina; Fort Carson, Colorado; Fort Benning, Georgia; Quantico Marine Base, North Carolina; and, GM’s own Proving Grounds in Michigan.
After a little more than a year of research and more than 20 attempts to get the right materials, an Air Force Academy cadet and professor have developed a kind of goo that can be used to enhance existing types of body armor.
As part of a chemistry class project in 2014, Cadet 1st Class Hayley Weir was assigned epoxy, Kevlar, and carbon fiber to use to create a material that could stop a bullet.
The project grabbed Weir’s interest.
“Like Under Armour, for real,” she said.
The materials reminded her of Oobleck, a non-Newtonian fluid — which thickens when force is applied — made of cornstarch and water and named after a substance from a Dr. Seuss book, and she became interested in producing a material that would stop bullets without shattering. An adviser suggested swapping a thickening fluid for the epoxy, which hardened when it dried.
“Up to that point, it was the coolest thing I’d done as a cadet,” Weir, set to graduate this spring, told Air Force Times.
But soon after, she had to switch majors from materials chemistry to military strategies. That presented a challenge in continuing the research, but she teamed up with Ryan Burke, a military and strategic studies professor at the academy.
Burke, a former Marine, was familiar with the cumbersome nature of current body armor, and he was enthused about Weir’s project.
“When she came to me with this idea, I said, ‘Let’s do it,'” he said. “Even if it is a miserable failure, I was interested in trying.”
The science behind the material is not new, and Burke expected that the vast defense industry had pursued such a substance already. But a search of studies found no such work, and researchers and chemists at the Air Force Civil Engineer Center said the idea was worth looking into.
They began work during the latter half of 2016 using the academy’s firing range, weapons, and a high-speed camera. Burke got in touch with Marine Corps contacts who provided testing materials.
In the lab, Weir would make the substance using a KitchenAid mixer and plastic utensils. It was then placed in vacuum-sealed bags, flattened into quarter-inch layers, and inserted into a swatch of Kevlar.
At first, during tests with a 9 mm pistol, they made little headway.
“Bullets kept going straight through the material with little sign of stopping,” Weir told Air Force Times. After revisiting their work and redoing the layering pattern, they returned to the firing range on December 9.
Apprehensive, Weir fired on the material.
“Hayley, I think it stopped it,” Burke said after reviewing the video. It was the first time their material had stopped a bullet.
This year, they traveled to the Air Force Civil Engineer Center to present their work and up the ante on their tests.
Weir’s material was able to stop a 9 mm round, a .40 Smith Wesson round, and a .44 Magnum round — all fired at close range.
During the tests, 9 mm rounds went through most of the material’s layers before getting caught in the fiber backing. The .40 caliber round was stopped by the third layer, while the .44 Magnum round was stopped by the first layer.
The round from the .44 Magnum, which has been used to hunt elephants, is “a gigantic bullet,” Weir told Air Force Times. “This is the highest-caliber we have stopped so far.”
Because it could stop that round, the material could be certified as type 3 body armor, which is usually worn by Air Force security personnel.
The harder the bullet’s impact, the more the molecules in the material responded, yielding better resistance. “The greater the force, the greater the hardening or thickening effect,” Burke said.
“We’re very pleased,” said Jeff Owens, a senior research chemist with the Air Force Civil Engineer Center’s requirements, research, and development division. “We now understand more about what the important variables are, so now we’re going to go back and pick all the variables apart, optimize each one, and see if we can get up to a higher level of protection.”
The model Weir and Burke created uses 75% less fabric than standard military-style body armor.
It also has the potential for use as a protective lining on vehicles and aircraft and in tents to protect their occupants from shrapnel or gunfire.
“It’s going to make a difference for Marines in the field,” Burke said.
On the civilian side, the material could aid emergency responders in active-shooter situations.
“I don’t think it has actually set in how big this can get,” Weir said in early May. “I think this is going to take off and it’s going to be really awesome.”
While the ultimate use of the material is unclear, the US Army and Marine Corps are reportedly looking for ways lighten the body armor their personnel use.
A study by the Government Accountability Office, cited by Army Times, highlighted joint efforts to lower the weight of current body armor, which is 27 pounds on average. Including body armor, the average total weight carried by Marines is 117 pounds, while soldiers are saddled with 119 pounds, according to the report.
The Army and Marines have looked into several ways to redistribute the weight soldiers and Marines carry, including new ways to transport their gear on and around the battlefield. The GAO report also said each branch had updated its soft armor, in some cases cutting 6 to 7 pounds.
Memorial Day is a time to remember the lives lost to preserve American freedom. It’s a solemn holiday most often spent by sharing a day off with loved ones, usually around a grill with a cold one in your hand. But as you enjoy a burger and a beer and share laughs with friends and family, take a minute to remember everyone who can’t be with their loved ones.
It’s really astonishing just how many people celebrate Memorial Day in America by having a cookout, watching a parade, and enjoying a frosty beverage. In fact, a staggering sixty percent of American households will spend one day during the Memorial-Day weekend at a barbecue — second only to Independence Day. Memorial Day is the second biggest period for beer sales in America and $1.5 billion will be spent on meat and seafood.
Even more astonishing is the number of volunteers that go out to cemeteries to plant the Stars and Stripes on the graves of fallen troops and veterans. While 1.5 million people watch more than a thousand active duty service members in the National Memorial Day Parade and 900,000 people gather for the Rolling Thunder Memorial Day motorcycle rally in our nation’s capital, over 260,000 graves at Arlington National Cemetery will be adorned with flags by volunteers.
More than 45 million men and women have served the United States in a time of war (you know, doing that thing we all got our National Defense Service Medal for) and more than 1.35 million American men and women have died fighting in armed conflicts around the globe. So, with all these numbers in your head, remember that the most important of all is “three.” At 3:00 p.m. on Memorial Day, Americans everywhere will put down the burger, turn off the TV, and take a moment in silence.
The National Moment of Remembrance is where we forget our personal and political differences for and come together as a nation to remember those who lost their lives fighting for our rights, freedoms, and privileges as Americans — so we can enjoy that burger, watch that TV, and ride our motorcycles.
So, take a moment. 3pm, Memorial Day. Be there.
