On Jan. 7, the United States lost Brigadier General Anna Mae McCabe Hays, who died at the age of 97.
It took a while for women gain ground in the military. Hays didn’t let double standards or biases against her gender limit her during her military career. As a result of her fortitude and determination, she is now best-known for becoming the first female to be promoted to a General Officer rank in the United States armed forces.
Hays was born on Feb. 16, 1920, in Buffalo, NY. She had a love for music and would have applied to Julliard, but her parents could not afford the tuition.
Hays also had an affinity for nursing; as a young child, she would practice tying bandages on wooden chairs and when she grew up, she decided to attend Allentown Hospital School of Nursing. After graduation in 1941, she lent her talents to the American Red Cross, but she soon learned that she could aid her country in a higher capacity.
After the attack against Pearl Harbor, Hays drove to Philadelphia where she signed up for the Army Nursing Corps. Her first assignment was a military base hospital in Assam, India, where she treated construction workers and Army engineers who had the task of building a road to China.
Amputations were a common occurrence and Hays witnessed — and assisted in — many of them. Impressively, at the end of WWII, Hays decided to stay in the Army. She went on to deploy to South Korea and set up the first hospital in the city of Ichon.
Hays also helped lobby change for women by suggesting that married officers who became pregnant should not be automatically discharged. She also helped change the discriminatory age limitations that restricted women from joining the Army Nurse Corps Reserve.
If that wasn’t enough, Hays also established the Army Institute of Nursing, which is now Walter Reed National Military Medical Center at Andrews AFB, Maryland. Her promotion to Brigadier General on June 11, 1970 was the first time a woman had worn stars on her shoulders. President Dwight D. Eisenhower’s wife, Mamie, was present at her ceremony and presented her with the very stars her husband received when he was promoted to the same rank in 1941.
After three decades of military service, Hays stated, “If I had it to do over again, I would do it longer.” A woman of steadfast fortitude and astonishing work ethic, Hays paved the way for future leaders of our armed services — men and women alike — and she will never be forgotten.
Shortly after he became an officer in the Marines, John Kelly met a captain who told him that he should approach his new position as “a real professional.”
“A doctor who doesn’t read peer articles and stay attuned to the developments in his field is not the kind of doctor you would want to go to, and the same is true for officers in the Marine Corps,” the captain told him.
“He got me going on reading, specifically focused on military things, and I just never stopped,” Kelly said.
The Wall Street Journal reported August 4 that Kelly picked up C.S. Forester’s 1936 novel “The General” after accepting the role of chief of staff, just as he did after accepting the role of DHS chief six months prior — and just as he did every time he was promoted during and after his military career, since he was 25 (he is now 67).
It’s essentially a parable about the dangers of patriotism and duty unaccompanied by critical thinking. Kelly went through it again to remind himself “of what to avoid as a leader,” the Journal reported.
“The General” tells the fictional story of General Sir Herbert Curzon, a leader in the British Army during World War I. Curzon is an unremarkable man who attained his position of power largely through luck and the failings of the superiors who preceded him. He is eventually put in charge of 100,000 men during WWI, where he leads many of them to their death and loses his leg in the process. Despite his failings as a leader, he is lauded in his retirement as a military hero.
When Kelly read the book as a young officer, he thought of his captain’s words on leadership.
Describing Curzon, Kelly wrote in “The Leader’s Bookshelf,” “He is a brave guy, a dedicated guy, a noble guy, but a guy who in the end has become a corps commander — a three-star general — and when presented with an overwhelming German attack couldn’t figure out how to deal with it because he’d never developed himself intellectually.”
Every time Kelly has read the book, he wrote, he’s noted where he was at that point in his life, and how the novel’s lesson resonates with him.
He wrote that, “depending on as you get older and higher in rank, it’s a different book every time you read it. When a lieutenant reads that book it’s different from when a lieutenant general reads it. … So it’s just kind of a fun thing I’ve done over the years and with this book in particular just to remind me of the critical importance of thinking.”
Georgia Army National Guard Spc. Jason A. Warren, an aircraft powertrain repairer with the Marietta, Georgia-based Company D, 1st Battalion, 171st Aviation Regiment, and his wife Cortney garnered national media attention on Feb. 9, 2018, when their son, Lucas, was named the 2018 Gerber Spokesbaby.
The Warrens were amazed when they received the news of Lucas’ win.
“Absolute shock,” said Jason. “It was hard to believe he won out of 140,000 entries.”
Lucas, diagnosed with Down syndrome, is the eighth Gerber baby since the contest began in 2010. Inspired by the original Gerber baby sketch of Ann Turner Cook, families began sharing their baby photos with Gerber. In response, Gerber launched its first official photo search competition in 2010.

“We hope this opportunity sheds light on the special needs community and educates people that with acceptance and support, individuals with special needs have potential to change the world,” said Cortney. “Just like our Lucas.”
The Warrens hope other families with special needs children can look to Lucas as a source of inspiration.
“We hope this will help people kick-start their own lives and give them more confidence,” said Jason. “They might think if Lucas can do this, what can I do in my life?”
The winning photo shows Lucas, sitting in an overstuffed chair, grinning from ear to ear wearing a black and pink polka-dot bow tie.
“He is very outgoing and never meets a stranger,” said Cortney. “He loves to play, loves to laugh, and to make other people laugh.”
“He is just the absolute cutest thing ever,” said Staff Sgt. Misty D. Crapps, supply sergeant with Company D, 171st Aviation Regiment. “He always smiles at everybody he sees.”

Jason looks forward to continued service in the Georgia Army National Guard. He feels a sense of pride and family being part of the organization.
“I absolutely love the Guard: the ability to help my community and serve my country,” said Jason. “The benefits of service are always great to have, and it allows me to serve my country the way I want to.”
The fellowship of his teammates in his aviation unit also reinforces the feeling of family.
“The Guard has been with me with everything I’ve ever done,” said Jason. “Through my grandmother’s passing, when I had shoulder surgery, they’ve helped Cortney and me a lot, and they are a second family to us.”

The aviators and Guardsmen in Jason’s unit share his feeling for service in the Guard and look forward to his continued service.
“He always volunteers to do the little things which are not part of his job description to make the unit better,” said 1st Sgt William W. Adcock of Company D, 171st Aviation Regiment. “Specialist Warren is a fantastic Guardsman. He does what we all do: dedicates his time and personal energy to serve the people of this state and the United States.”
Jason plans to re-enlist in March 2018 for another six years and hope Lucas sees him and understands the importance of service.
“I hope one day Lucas will see I was in the military and has a sense of pride,” said Jason.
The largest non-nuclear weapon in the Air Force‘s arsenal recently got an upgrade from Boeing, Air Force officials told Military.com.
While they couldn’t comment on how many GBU-57 weapons received the upgrade for operational security reasons, “the Enhanced Threat Response IV modification improved the weapon’s performance against hard and deeply buried targets,” Air Force spokeswoman Ann Stefanek said. The announcement was first reported by Bloomberg News.
Known as the Massive Ordnance Penetrator, or MOP, the bomb is a bunker buster meant to take out hard, deeper-rooted areas, such as underground lairs. While the MOP weighs in at 33,000 pounds, its warhead is only roughly 5,300 pounds.
Whether or not the MOP is currently deployed was not disclosed.
In October 2017 The Aviationist website posted an account of Northrop Grumman-made B-2s simulating airstrikes across various targets in Missouri. According to the witness, the strikes, simulated in the Ozarks, resembled a practice run in a mountainous terrain such as Afghanistan or North Korea.
Meanwhile, citing a test and evaluations report, Aviation Week recently reported that three B-2s, each armed with a GBU-57, struck at targets at the Army’s White Sands Missile Range in New Mexico in May, 2017.
The MOP outweighs the Air Force’s Massive Ordnance Air Blast, or MOAB, bomb. However, the air-burst MOAB — first deployed in combat in 2017 — is the most powerful conventional bomb with 18,000 pounds of explosives, equivalent to about 11 tons of TNT.
The 21,600-pound GBU-43 — nicknamed “mother of all bombs” — dropped from an MC-130special operations cargo plane onto a specific location in Nangarhar province in eastern Afghanistan in April 2017. The intention was to take out militants affiliated with the Islamic State of Iraq and Syria’s branch Khorasan, or ISIS-K, amassed in a tunnel complex.
That strike killed at least 94 militants, a U.S. military official said at the time.
Learning to snowshoe, ski and stay warm in the cold might sound like a fun hobby.
But for Soldiers at the Cold Weather Leaders Course at the Northern Warfare Training Center here, learning these things can mean the difference between a failed or successful mission and it could also be the difference between life and death.
Staff Sgt. Jonathan Tanner, an instructor at the NWTC, was deployed twice to Afghanistan, once from 2007 to 2009 and another time from 2014 to 2015.
During one of those tours, he said, he recalls being over 9,000 feet in the mountainous terrain of the eastern part of the country during a heavy snowfall, with snow drifts up to 12 feet tall.
“The snow stopped us dead in our tracks,” he said. “We were trying to remove snow from equipment with our e-tools.”
During a Black Hawk resupply mission, the helicopter had no place to land so it hovered above the snow while the crew chief jumped out, post-holing himself in the snow shoulder high. Post-holing is a term for sinking into the snow waist or chest high when not wearing skis or snowshoes. The crew chief had to grab the struts of the helicopter to be pulled out, Tanner recalled.
No one had skis or snowshoes and “we couldn’t do our jobs.”
Tanner and the other instructors at NWTC say they are professionally and personally invested in ensuring those kinds of situations never happen to Soldiers again.
Sgt. Sarah Valentine, a medic and an instructor, said most Soldiers that come to the school don’t know how to snowshoe, ski or survive in the cold. Instruction begins with baby steps.
First, they learn how to wear their cold weather clothing, she said. Then they learn to walk with snowshoes. A little later they learn to walk on snowshoes carrying a rucksack, and finally, they learn to tow an ahkio, or sled, carrying 200 pounds of tents, heaters, fuel, food and other items.
Next, they advance to skis, learning how to walk uphill, how to turn and stop going downhill, and then how to carry a rifle and rucksack going cross-country.
Staff Sgt. Jason Huffman, a student, said that besides enduring the cold, pulling the ahkio was the most challenging aspect of the school.
For that portion of the training, four of about 10 Soldiers are harnessed to the sled like sled dogs. Huffman said going on level terrain is easy, but most of the terrain near the school isn’t level and it is challenging to pull the ahkio uphill, especially from a dead stop.
Going downhill, the challenge is holding the ahkio back so it doesn’t get away, he said. When the students get tired, they are replaced by other students in the squad, who in turn rotate back out once they’re tired.
Spc. Tamyva Graffree, a student from Newton, Mississippi, said pulling the ahkio uphill was the most challenging part of the course. Of going downhill, she said it would have been nice to pile on and ride it down.
Staff Sgt. Manuel Beza, an instructor and medic here, said the students are not allowed to ride the ahkio downhill. “It will definitely go fast. But if they did that, it would be a bad day. The ahkio has no brakes and no way to steer.”
Beza said he sympathizes with the students’ pain. While the ahkio can be handled almost effortlessly over level terrain, going even 500 feet uphill can tire Soldiers out.
But when roads are nonexistent and vehicles break down from the cold, ahkios give the Soldiers the option to move out with their gear, he said.
Once students demonstrate competence on snowshoes, they are given a set of “White Rocket” skis, which can be used in both downhill as well as cross-country skiing.
The difference between a dedicated downhill or Nordic ski and the White Rocket ski is that the heel in the White Rocket isn’t locked into the ski binding so the foot can move similar to walking, said Sgt. Derrick Bruner, an instructor.
A Soldier can learn to use snowshoes in two hours, but about 40 hours is allotted for ski training at the school.
Because training time is limited, Soldiers learn just the basics, Bruner said. For instance, they learn to stop and turn going downhill using a wedge movement instead of a more advanced technique like turning or stopping with skis parallel.
A wedge consists of bringing the toes of the skis together and the heels of the skis out and carving into the snow on the inner edges of the skis by rotating the ankles inboard.
Skipping the fancy art of parallel skiing cuts down on injuries as well, he said, because there’s less chance of them crossing.
Going uphill involves side-stepping or walking up in herringbone fashion, which is the opposite of the wedge, with toes of the skis outboard, heels in.
To assist with uphill climbing, Soldiers apply special wax to the bottom of their skis.
Sgt. Dustin Danielson, a student, explained that the wax goes on just the middle third of the ski where the person’s weight is. He made hatch marks with the wax on his skis and then took a piece of cork to spread it evenly all around.
After skiing just a few kilometers, the wax tends to come off and more has to be applied, he said.
Sgt. Jessica Bartolotta, a student, said they were not given wax on the first day. On the second day of training, students were allowed to wax their skis. The point, she said, was to illustrate just how important the wax is in providing friction to grip the snow going uphill. She said the wax had no noticeable effect on slowing the skis going downhill.
Another thing the instructor did early on during the first day of ski training was to observe how well the Soldiers were skiing and to break them up into three groups of skill levels so the slow learners wouldn’t hold back the more natural skiers, she said.
Bartolotta said skiing was her favorite part of the course and she plans to take it up as a hobby.
Sgt. Chris Miller, a student from Little Rock, Arkansas, said this was his first time skiing and he fell a lot. “I’m a big guy and it’s hard to keep my balance.”
Miller measured his progress by the number of falls. The first day he said he fell 12 times and just once after three days. He said he’s still trying to perfect the art of stopping using the wedge.
Sgt. Shamere Randolph, another student, said he fell a bunch of times as well, but prefers skis to snowshoes because it’s much faster to get from point A to point B.
Sgt. Bruno Freitas, a student, said that his skis were difficult to use on the last day of training when the temperature rose and the snow turned to slush. In below freezing conditions, the skis work much better than they do in slush, he said.
About four years ago, the Army decided to do away with ski training at the NWTC, said Steven Decker, a training specialist. He said he’s not sure why the decision was made, but said he’s glad that skiing was reintroduced this year.
Canadians and Japanese go everywhere on skis, he said. They find it very relevant to mobility. In fact, “when the Japanese attend the course here, they can ski circles around us.”
The downside to skiing, he said, is that it takes a while to learn. For an entire platoon or company to move out on skis, it might take an entire winter and a lot of training time dedicated to making that happen.
But he and the other instructors all agreed that learning to ski is worth the time and effort.
Sgt. Derrick Bruner, an instructor, said snowshoes are “loud, slow and clunky” to use compared to skis and that skis provide better floatation over the snow. “Skis are a million times better once you get the technique down.”
Staff Sgt. Jack Stacy, an instructor, said when he first arrived at NWTC, he went out into the terrain in a vehicle that broke down. He didn’t have skis or snowshoes with him and ended up having to walk back to headquarters, “post-holing” it back all the way.
“It was the most miserable time I’ve ever had here,” Stacy said. “I’ve always made sure my skis or snowshoes are handy ever since.”
Kim Jong Un’s arrival in Vietnam for a second summit with President Donald Trump took an unusual turn when an aide appeared to miss his cue during a grand entrance.
Video footage of Kim’s arrival in Dong Dong, on the China-Vietnam border, shows the North Korean leader walking down a red carpet ramp from his personal armored train.
He initially descends alone. A few seconds later, an aide appears to realise what is going on, and quickly runs down the ramp to join Kim.
You can the moment in this video, via the Filipino ABS-CBN news channel. The aide’s sprint down the carpet comes around the 14-second mark:
The entourage had just completed a marathon 2,000-mile train ride from Pyongyang, across a vast expanse of southern China, which lasted two and a half days.
Experts say that Kim’s decision to travel by train could have been to avoid the appearance of being reliant on China, after he received significant attention for borrowing plane from the government-owned Air China to get to his last summit with Trump in Singapore.
The optics of Kim travelling by train could also remind North Koreans of Kim’s grandfather, who used the same train to get to countries like Vietnam as well as the Soviet Union and Eastern Europe, The Associated Press reported.
Trump has characterized the summit as a follow-up to the leaders’ first summit in Singapore in June 2018, when North Korea made a vague commitment to working toward denuclearization.

Pyongyang appears to have made little progress on that front since the first meeting. US intelligence and North Korea experts have warned that North Korea is unlikely to give up its nuclear arms.
Trump told the Governors’ Ball on Feb. 24, 2019, that he was “not pushing for speed” with North Korea’s denuclearization.
However, he tweeted on Feb. 25, 2019: “With complete Denuclearization, North Korea will rapidly become an Economic Powerhouse. Without it, just more of the same. Chairman Kim will make a wise decision!”
“This is actually how we would get SEALs off the ship submerged,” Senior Chief Mark Eichenlaub told Business Insider.
“So you would stick a platoon of SEALs in here, 14 guys … you fill this chamber with water until you match the outer sea pressure. Once the pressure in and outside the ship match, the hatch will lift off open, and they can swim out of a fully filled chamber into open ocean.”
Once the chamber is filled with water, matching the pressure inside and out, “there’s an internal locking mechanism that would open” the top hatch where SEALs swim out, Senior Chief Darryl Wood told Business Insider.
The SEALs can then swim to retrieve what is known as a special-forces operations box, which would be filled with weapons and needed gear, from the tower.
In addition to getting SEALs off the ship, lockout trunks can be used for the entire crew to escape in case the submarine is downed.
This video gives a close-up look at the lockout trunk:
U.S. Army officials in Korea announced April 18, 2018, that an Eighth Army memo warning soldiers about potentially “bad Anthrax” vaccinations given on a large scale is “completely without merit.”
The announcement follows an explosion of activity on social media after an April 10, 2018 memo from the 2nd Battalion, 1st Air Defense Artillery Regiment in Korea began circulating on Facebook. The memo was intended to advise soldiers who possibly received bad Anthrax vaccinations from Fort Campbell, Kentucky and Fort Drum, New York from 2001-2007 for Operation Enduring Freedom and Operation Iraqi Freedom that they may qualify for Veterans Affairs benefits.
“The purpose of this tasking informs soldiers who received bad Anthrax batches from Ft. Campbell and Ft. Drum from 2001-2007 for OEF/OIF IOT notify possible 100 percent VA disabilities due to bad Anthrax batches,” the memo states.
Military.com and other media organizations reached out to the Army on April 16, 2018, to verify the memo. Eighth Army officials in Korea sent out a statement at 9:33 p.m. on April 18, 2018.
“Second Battalion, 35th Air Defense Artillery Brigade recently published an internal memorandum with the intent of informing soldiers of the potential health risks associated with the anthrax vaccine based on information they believed was correct,” Christina Wright, a spokeswoman for Eighth Army said in an email statement.

“Defense Health Agency representatives have verified the information is false and completely without merit. Once the brigade discovered the error, the correct information was published to their soldiers.”
The Eighth Army’s statement also stated that the “potential side effects of vaccines, including anthrax, are generally mild and temporary. While the risk of serious harm is extremely small, there is a remote chance of a vaccine causing serious injury or death.”
The author of the post — Dee Mkparu, a logistics specialist in U.S. Army Europe, said that it was not clear if the memo was authentic but thought it was important to make the information public.
“This information was gathered from other veterans through Facebook; the validity of this data has not been fully vetted but I felt it was more important to share this as a possibility that to let it go unknown,” Mkparu said.
Mkparu updated his post with 17 potentially bad batch numbers of Anthrax vaccine allegedly found at more than a dozen military installations across the United States as well as Kuwait and South Korea.

“Please get with your VA representative and look into it. Even if it turns out to be false perhaps the Anthrax concerns from so [many] people will bring the issue into the light.”
Francisco Urena, the secretary of the Massachusetts Department of Veterans’ Services secretary was quick to call the memo “a fake” in a recent Tweet, advising service members not to share their personal information.
“There is a fake memo circulating social media about a bad batch of anthrax vaccination for VA Compensation,” Urena tweeted. “This is a scam. Do not share your personal information. This is not how VA Claims are filed.”
VA disability benefits are granted for health conditions incurred in or caused by military service, according to the Eighth Army statement.
“The level of disability is based on how a service-connected condition impacts daily life,” according to the statement. “In those rare cases, VA disability or death benefits may be granted.”

The incident reportedly forced the crew of the aircraft to prematurely end its mission and was first reported by CNN. Monday’s intercept is the latest in a string of “unsafe” intercepts that the Russian military has conducted.
In November 2017, a Russian Su-30 fighter flew as close as 50 feet before turning on its afterburners while intercepting a US Navy P-8A Poseidon anti-submarine warfare aircraft over the same area.
The maneuver forced the plane to enter its jet wash and caused it to undergo a 15-degree roll, Lt. Col. Michelle Baldanza, a Pentagon spokeswoman, said at the time.
The US Navy has been conducting reconnaissance missions over the Black Sea at a high rate since the annexation of Crimea by Russia in 2014.
There have been a number of aerial intercept incidents between US and Russian aircraft over the past year, even outside of Europe.
The most recent intercept occurred over Syria in December, and saw two US Air Force F-22s be intercepted by Russian Su-25 and Su-35. The US Aircraft had to fire flares as warnings to the Russian jets, one of which “had to aggressively maneuver to avoid a midair collision.”
Russia has denied the incident in Syria took place.
United States troops stationed in Syria have yet to receive guidance on their mission, including the basic rules of engagement, according to a military official in a CNN report published Nov. 4, 2019.
Some military commanders deployed to Eastern Syria were reportedly still waiting to receive their directives to guard oil fields in the region. For some of these troops, it was unclear where their destinations would be and how long they were expected to stay there, according to CNN.
President Donald Trump and his congressional allies in recent weeks have shown interest in the oil fields in the country, even deploying additional troops and armored vehicles to protect the oil reserves.
“What I intend to do, perhaps, is make a deal with an ExxonMobil or one of our great companies to go in there and do it properly,” Trump said on Oct. 27, 2019, adding that he wanted to “spread out the wealth.”
“The oil is so valuable for many reasons,” Trump added.
US troops in northeastern Syria were called back after Trump ordered their withdrawal, ahead of Turkey’s military offensive against Kurdish forces earlier this month.
US troops in Northern Syria.
But Trump also ordered troops into the region to protect oil fields from Islamic State militants, Syria, and Russia.
Roughly 1,000 US troops were deployed to the region when Turkey embarked on its offensive on Oct. 9, 2019. After accounting for the new troops, around 900 US service members are expected to remain.
The Syrian Democratic Forces, the majority-Kurdish forces that were allied with the US for the war against ISIS, have operated the oil fields after seizing them from the terrorist group in 2017. The SDF has been selling the crude oil to the Syrian regime through a sanctioned broker, according to a Wall Street Journal report, citing sources familiar with the situation.
The confusion wrought from the abrupt military repositioning also comes shortly after artillery rounds landed about 1 kilometer away from US troops. US forces patrolling northeast Syria on Nov. 3, 2019, reportedly noticed the artillery fire, according to the Military Times. No US service members were injured.
The event follows another similar incident on Oct. 11, 2019, when Turkish artillery fire landed a few hundred meters away from a location with US forces. Following the incident, a US official demanded that Turkey “avoid actions that could result in immediate defensive action.”

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!
America’s longest-serving bomber recently demonstrated the ability to lay down a devastating minefield at sea without putting itself and its crew in harm’s way, a game-changing capability should the US suddenly find itself in conflict with another naval power.
A US Air Force B-52H Stratofortress heavy long-range bomber out of Andersen Air Force Base on Guam dropped what appear to be new 2,000-pound derivatives of the Quickstrike-ER (extended range) sea mine during the Valiant Shield exercises in the Pacific, The Drive first reported Sept. 19, 2018, noting that the mine is powerful enough to bring down even the largest of naval vessels.
The weapons used during the drills were, in fact, new one-ton Quickstrike-ER naval mines, Lt. Cmdr. Darin Russell, the Valiant Shield Joint Information Bureau director, confirmed to Business Insider, and the test Sept. 17, 2018, was the first tactical test of the previously-unseen configuration. Valiant Shield is an exercise designed to strengthen interoperability and communication between the service branches, making it an ideal opportunity to test an asset like the Quickstrike mine, which is deployed from the air for use at sea.
The B-52 carried a total of four Quickstrike mines into testing and fired three, Russell revealed, identifying the fourth one as a spare. He indicated that the testing was successful.
The iconic bomber can lay down an entire minefield in a single pass without putting itself in the firing range of certain enemy anti-aircraft systems. The mines, general purpose bombs modified to serve as sea mines, are launched from great distances and typically deployed to relatively shallow waters where they could be used to render strategic waterways and ports impassable or inaccessible, as well as prevent amphibious assaults.
Using aircraft to lay mines is a concept that dates back to World War II, but at that time it was difficult to create adequate minefields with any real accuracy at high-altitudes. During Vietnam and the Gulf War, mines were dropped into position from lower altitudes with reduce airspeeds, putting aircrews at risk.
The first tactical test of a precision, standoff air-dropped mine occured during an iteration of the Valiant Shield exercise in September 2014, when a B-52H dropped a Quickstrike-ER, a sea mine variation of the 500-pound Joint Direct Attack Munition Extended Range (JDAM-ER). Known as Flounders, these mines can be put down by aircraft operating more than 40 miles away, an ability made possible by the extended range wing kit, the Diplomat introduced in 2017.
In 2016, the weapon was test-fired from an F/A-18 during that year’s iteration of Valiant Shield.
There is another short-range variant called the Skipjack which packs more explosive punch. The 2,000-pound Quickstrike-J can be deployed by any aircraft capable of carrying a JDAM. While it was first tested on a B-52, testing has continued with B-1 bombers and F/A-18 fighters, according to Defense One.
Whereas the older generation Quickstrike mines required aircraft to fly at lower altitudes and lower speeds over the target area, putting US aircraft in danger, the newer generation systems can be deployed by planes flying at the same tactical airspeeds and altitudes as those required for the JDAMs.
A 2,000-pound variant of the Quickstrike-ER offers the same explosive power of the Slipjack combined with the range of the Flounder. While the mine is being tested on the B-52, the weapon could presumably be deployed on any aicraft able to carry a JDAM, including the stealth B-2 Spirit bomber. US air assets could penetrate strategic areas and seal off shipping lanes and blockade ports with fewer mines.
American B-52 crews have actually practiced dropping older versions of the Quickstrike mines in Russia’s backyard, most recently in 2015 during the Baltops exercises in the Baltic Sea.
The ability to lay powerful mines from a distance would likely come in handy in a number of flashpoint areas, such as the contested South China Sea, where China is fortifying man-made islands. In recent months, US Air Force B-52s have made regular flights through the region, sending an unmistakable message to a rival.

Hundreds gathered at Iowa Veterans Home Cemetery this afternoon to pay their respects to a once homeless Korean War Navy veteran named Charles ‘Chuck’ Lanam. They didn’t know Lanam — and they didn’t know each other — but today on the burial hill the strangers came together as family.
“This man would have been buried on his own,” said Simon Conway, Des Moines resident and radio host at 1040 WHO. “There was literally nobody coming to this … this man had nobody, no family, no friends. There was no one to carry his casket, there was no one to give the flag to … no one to tell us about our grateful nation. Today, Chuck was laid to rest with full military honors and around 400 Iowans in attendance. We make a difference.”
Lanam was born September 16, 1934 in Fairfield, Iowa. He was the son of Christopher and Marian (Byers). He attended school in the Fairfield area. He served four years in U.S. Navy aboard USS Valley Forge during the Korean conflict. After retiring from the military, Lanam resided in Tennessee and Iowa and did electrical contracting. He never married. He was homeless for a number of years until February 2015, when moved into the Iowa Veterans Home. He remained there until he passed away.
This veteran, who never owned a computer, much less a had Facebook page, posthumously became a viral topic on the social media platform last week. Mitchell Family Funeral Home director Marty Mitchell reached out to his friends and community after Lanam’s death asking for their help in honoring this veteran’s life with this post
I’m sitting in my office right now and contemplating the rest of the week- and really struggling with one thing that I would like to open up and share with all of you- and no, not a joke, something real. On Monday, we are going to bury a man who served our country honorably, and probably before many of us were born. He has no family – absolutely no family, so our staff and the chaplain from IVH will gather on a quiet hillside at IVH and put this man to rest. No pallbearers, no mourners, no flowers, no one to even present a flag to saying his service was recognized. If you so desire and it’s in your hearts, we are having a service at 1:30 p.m. at the cemetery at IVH. Even though you did not know him, this man Charles Lanam, you are welcome to come and honor his life or serve as a pallbearer or even as important, send your prayers. Death equalizes us in the end, but before that time, appreciate that you do have a family. God bless you all my friends!
That request was shared over 1,700 times. It attracted Patriot Riders and members of the Veterans of Foreign Wars and the American Legion. A suit was donated for Lanam to be buried in, and pallbearers volunteered. In response, Mitchell posted the following to his page:
“I truly think Mr. Lanam is smiling down at all of you for caring about him. He might be overwhelmed, but I do think he is happy. He now gets to rejoin his mom, his dad and his sister who went on before. Thanks to the Iowa Veterans Home for making his last years a home and family- a change he deserved from being homeless, and thanks for making his resting spot available. God bless all of you for focusing on what is important in life…”
This afternoon, Lanam’s coffin was draped in a flag with hundreds in attendance. “Last Wednesday, I expected to be standing on a lonely hill overlooking the veteran’s zone with Marty and a few staff members saying a quiet farewell to Chuck today,” Chaplain Craig Nelson said before beginning the eulogy. “Instead, I find myself surrounded by those who were moved by his story and wanted to come out so he might not be laid to rest alone.”
Mary Drake, business manager at Mitchell Family Funeral Home said any donations they receive in Charles’ honor will be sent to Iowa Veteran’s Home.
