On June 27, 1950, President Truman ordered U.S. forces to Korea.
Just two days prior, 90,000 communist troops of the North Korean People’s Army invaded their southern counterparts. This action prompted an emergency U.N. Security Council session to search for a resolution.
The USSR was boycotting the council due to the U.N.’s rejection of North Korea’s participation and missed their opportunity to veto the vote.
On June 27, President Truman made his announcement to the world that the U.S. would get involved in the conflict. Truman believed that the Soviets may have been behind the North Korean invasion because of their utilization of Soviet built tanks. Truman’s decision to enter the conflict was met with overwhelming approval from Congress and more importantly, the American people.
When the Korean War started, victory was far from assured. The North Korean attack on June 25, 1950 took the U.S. and South Korea by complete surprise and the Communists were able to make large gains in a very short amount of time.
The battle lines swung as wildly as the momentum of the war itself before grinding into months of stalemate as the two sides haggled at the negotiating table. Every time the pendulum shifted, more American and UN forces were captured by the North Korean and Chinese forces. The first reports of enemy atrocities filtered into the UN headquarters as early as two days after the invasion started.
The report found the Communist forces in Korea “flagrantly violated virtually every provision of the Geneva Convention” as well as Article 6 of the Nuremberg Tribunal Charter.
After just over three years of brutal fighting, an armistice was signed on July 27, 1953. Even to this day, no peace treaty has been signed and the two Koreas are technically still at war.
When the Nazi forces captured French Gen. Henri Giraud in World War II, they knew they had to put him somewhere truly secure. So they took him to Konigstein Castle, a prison they were sure was completely inescapable. He broke out in two years. In broad daylight. Wearing a comical hat and glasses as a disguise. On Hitler’s birthday weekend.
Giraud was a popular general when World War II broke out. He was a hero of World War I for leading a bayonet charge against machine guns at the Battle of St. Quentin in Aug. 1914. He was wounded in the battle and left for dead before being captured by the Germans. It only took the severely wounded officer two months to escape that time, a feat he pulled off by acting like he was a laborer in a traveling circus.
Between the wars, he upped his notoriety factor by earning France’s Legion de Honneur in combat with Moroccan rebels and holding a series of high-profile military positions through the French empire.
In World War II, he fought the Nazis in a string of battles in an attempt to keep his country free. In May 1940, he led a reconnaissance patrol in Northeastern France and was captured at a machine gun nest after a heavy exchange with German artillery.
The Nazis knew they had a problem. Capturing a general is great, but then you have to hold him, and this general was famous for being a hero in two wars and had already escaped a German prison camp once. So they took him to Konigstein Castle, a prison with on a high hill that featured tall walls, few windows, and constant nighttime patrols. The Germans called it inescapable.

In the castle, Giraud quickly began a long-term plan to escape. He learned German by convincing the prison to offer classes. Then he stole a map and began studying potential routes and pitfalls. He also figured out a method of communicating with his wife and others through coded messages that would get past the censors. For an entire year, he slowly built a rope out of twine.
The Germans had good reason to believe that Konigstein was inescapable. Between the high walls and the fact that the prison was built on a hill, Giraud would need to descend 150 feet of wall and cliff face before reaching the ground. The twine was to help with that.
Basic trainees in the Air Force are being issued “Stress Cards.” If basic training gets too hard or they need a time out they can just pull these out and the instructor has to stop yelling at them.
No joke. I heard it from my cousin. Or my friend John. My buddy swears he saw them being handed out to the new trainees. Kids today just don’t have the chutzpah my generation does. One time when I was platoon leader in Somalia, this kid handed me one and asked for a time out, I kid you not.
None of that is true, of course. The stress cards myth is usually attributed to the Air Force, due to the perceived ease of Air Force basic training, and the Chair Force reputation. Sometimes, Bill Clinton introduced them to the Army (because the 90s were that awesome). In the legend, they’re yellow, because if you need to use one, you’re yellow too! Even some Airmen are guilty of perpetuating it. Whenever someone hears about the stress card myth, they are usually doomed to repeat it.
There is truth to the myth, but it wasn’t the Army or even the Air Force. In the 1990s, the cards were issued to new recruits as a means of telling them of what their options were if they got depressed. It contained basic information such as chaplain services and what to tell your Recruit Division Commander, etc. instead of deserting or washing out. And they were blue, because if you need these services, you were probably blue too.
The Blues Card was not a Get Out of Jail Free Card, though some RDCs reported troops holding it up while being disciplined, trying desperately (and probably in vain) to use it in that way. If you waved this in your RDC’s face, he probably made you eat it.
The Army did issue “Stress Control Cards” which were the equivalent of a wallet-based mood ring. the recruit or soldier could put their finger on a special square, which would turn colors to indicate a range of stress levels, from “relaxed” to “most stressed.”
For those of you who used to be in the Army or Navy, imagine your Drill Instructor or RDC’s response to your waving this card around while they’re trying to discipline you. How would that have gone? Tell us in the comments below.
The U.S. Navy owns the oceans, ensuring freedom of navigation for allies and fighting fiercely when called upon.
But the Navy has a softer side too, filled with humanitarian relief and medical missions.The crown jewels of this effort are the USNS Mercy and the USNS Comfort — hospital ships with a thousand beds each.
1. The USNS Mercy and her sister ship were converted from massive supertankers. Each is 70,000 metric tons.
2. The Mercy is a mobile hospital, complete with 12 operating rooms as well as pediatric, trauma, and orthopedic areas.
3. While the Navy maintains hospital ships to provide mobile care to soldiers and Marines fighting ashore, the USNS Mercy has been primarily deployed on humanitarian missions in the Pacific.
4. Mercy is often deployed to Pacific areas where clinics, like the one below, provide basic care. Doctors can refer the patients to the USNS Mercy, which will then provide hospital-level services.
5. Patients are transported to the ship by helicopter or by “band-aid” boats.
6. When patients arrive, they are sent to the receiving area. Their medical needs will be diagnosed and they are then sent elsewhere on the ship for care.
7. When doctors need a better look at an injury, the use the onboard CT scanner.
8. For patients that require surgery, the 12 operating bays provide a modern, sterile environment for procedures.
9. Here, a doctor puts the final sutures in a patient after removing a six pound tumor from her.
10. The ship regularly trains for mass casualty events. This helps them support military operations where a lot of troops may be wounded and respond to humanitarian crises.
11. Children are welcome on the ship where onboard pediatricians treat them.
12. A pre-dental society sophomore student from the University of California-San Diego plays with a Timorese child during Pacific Partnership 2008.
13. A hospital corpsman gives a surgical screening to a child onboard the USNS Mercy in 2010.
14. Humans aren’t the only patients for the USNS Mercy. The ship deploys with U.S. Army veterinarians and veterinary assistants for treating livestock and pets as well.
15. Pets and nearby wildlife can be a vector for disease, so the services of the veterinary staff help protect the human population.
16. The Mercy maintains its own combat search and rescue helicopter and crew.
17. Sailors launch and recover the birds from the upper deck of the ship.
18. Even foreign military doctors help out aboard the USNS Mercy. In this photo, an Australian Navy dentist treats patients onboard.
19. A dentist with the South Korean Navy treats a patient onboard the Mercy.
20. The USNS Mercy crew also goes ashore to help partner nations. Here, an environmental health officer tests a water well that was just dug by Navy Seabees.
21. The Mercy has its own firefighters who ensure the safety of the other sailors and patients on the ship.

The search for an effective rapid-fire weapon, particularly in the latter 19th century, took on some innovative designs, most of them of dubious battlefield utility and rarely employed. All this changed when the U.S. Army adopted the famed Gatling gun in 1866, which could reliably fire up to 400 rounds a minute and had already proven itself in small quantities during the Civil War. John Gatling — ironically a physician — had suddenly made warfare far more deadly.
Here is a look at some early attempts at automatic weapons before Gatling turned them into the staples of warfare they are today.
1. Repeating Crossbows
The Polybolos was a large repeating ballista dating back to the 3rd century B.C. It was supposedly the invention of a Greek engineer named Dionysus, who worked at the large arsenal on the island of Rhodes. Fed by a large wooden magazine holding several dozen bolts of the weapon’s cradle, it allowed its crew to crank a large windlass back and forth, allowing it to achieve a far greater rate of fire than conventional ballistics.
A replica built by the Discovery show “MythBusters” proved that it could have been a very feasible weapon, but would have suffered from severe reliability problems.
A device similar in concept called the Chu Ko Nu was in use by Chinese soldiers as early as the 4th century B.C., but it was conceived more as a rapid fire light crossbow. Holding up to 10 bolts, the soldier could rapidly crank a handle and fire every couple of seconds, an astonishing rate of fire for a weapon at the time. The bolts were light and its range was short, but it was intended for mass formations and made up for its lack of power with volume of fire. To increase lethality, its bolts were sometimes coated in poison.
2. Coffee mill gun
The American Civil War saw widespread experimentation in weaponry, and among the most sought was a rapid fire battlefield gun that could support the infantry. The “coffee mill,” or Agar gun, the namesake of it’s inventor Wilson Agar and mounted on a light artillery carriage, was one such attempt. Standard .58 rifle cartridges were loaded in special steel tubes and were placed in a large hopper on top of the weapon. A hand crank fed the cartridges and allowed a rate of fire of up to 120 rounds per minute. The feeding mechanism resembled an old-fashioned coffee mill, giving it its nickname. President Abraham Lincoln witnessed a demonstration and was very impressed by the weapon’s performance, and a small number were purchased by the Union Army.
Despite its impressive rate of fire, the weapon had serious disadvantages. Reloading the steel tubes was cumbersome, making keeping up the rate of fire difficult, and their loss made the weapon useless. The feed mechanism was vulnerable to jamming, and the weapon was highly prone to overheating. Its range was no greater than a standard rifled musket. Though it saw some action, its flaws, and the few number purchased ensured it played only a minor role in the war, and it was quickly replaced by the far more effective Gatling gun.
One approach to rapid fire was the clustering of large numbers of single-shot barrels together that were fed by a single large breach, firing in sequence before being loaded in again. The Mitrailleuse, from the French word for grapeshot, was the pinnacle of this concept. The original design came from it’s Belgian inventor Captain Fafchamps in 1851, but many variants saw service in the French Army leading up to the Franco-Prussian war.
Carrying up to 50 barrels and mounted on an artillery carriage, the weapon was breech loaded using large steel blocks studded with ammunition. A small crank was then turned to manually fire each round. A skilled gunner on some types could achieve over 100 rounds a minute. The Reffye variant which was most commonly used by the French used 13mm rounds with a range of over 2,000 yards. Unlike a modern machine gun, it was used more as artillery, with all its ammunition being expended on a single point target.
By the time the Franco-Prussian war broke out, the French had slightly more than 200 Mitrailleuses in service. The Prussians, despite having few rapid fire weapons of their own, were not particularly impressed by their enemies wonder weapon. It’s inability to be targeted quickly, and it’s rapid expenditure of ammunition onto a single target, rendered it tactically inflexible and redundant to conventional artillery. The small numbers deployed also limited the weapon’s effectiveness. After losing the war, the French phased the Mitrailleuse out.
The long-awaited seventh movie in the Star Wars saga is close to hitting theaters, and nerds everywhere are beside themselves. While most young males in North America grow up with a love of Star Wars (or Star Trek, if you have poor taste), I didn’t really find myself catching onto the movies in the same way as most of my peers did… In fact, what really lured me to Star Wars was the space battles between sleek and mean-looking X-Wing fighters and the various spaceships of the Empire (the bad guys). That interest was further cemented by something I found out about Star Wars’ connection to aviation of the Second World War, which I’m far more a fan of, if we’re being honest.
If you’ve ever seen the original trilogy (Return of the Jedi, The Empire Strikes Back and A New Hope), you’ve probably seen the infamous Millennium Falcon spaceship in action, piloted by the gruff, sarcastic Han Solo (played by Harrison Ford, a huge aviation buff), and co-piloted by his massive furry beer buddy, Chewbacca. The cockpit of the Falcon, if you pay close attention, actually seems to resemble another flying vehicle, though one from a very long time ago.
I’m talking about the Boeing B-29 Superfortress, one of the US Army Air Force’s strategic bomber workhorses of the Second World War, and the aircraft most famously associated with dropping the atomic bombs on Hiroshima and Nagasaki, decisively ending the war in the Pacific Theater.
George Lucas, the creator of Star Wars, apparently developed an affection for the B-29 during the time he spent researching aerial dogfights of WWII to enhance the realism of the space battles fought between X-Wings and TIE Fighters of the Rebels and the Empire respectively. He had set engineers design the cockpit of the Falcon such that it matched the view facing forward from the cockpit of a B-29 (peering over the pilots’ shoulders). After viewing over 25 hours of combat footage and gun camera imagery, Lucas included gunner stations aboard the Millennium Falcon, similar to those you’d find on a B-29 or a B-17 Flying Fortress. A few of the characters used such gun (or laser) turrets to good effect against marauding TIE Fighters in a similar manner to how gunners aboard bombers during WWII would engage enemy interceptor fighters sent up to shoot them down.
Lucas needed his spaceships to possess unique sounds that were fitting of their futuristic nature, so he once again turned to WWII-era aviation to help with meeting his goals. As sounds couldn’t easily be synthesized in the same way that studios can today, Lucas’ sound engineers needed to record other noises and modify them to get what they were after. One engineer was sent out to the Reno Air Races in Nevada, where he was allowed to lay down near a pylon (something you most certainly cannot do today) and record the noise of P-51 Mustang racers screaming overhead. After slowing down the recorded track, they mated it to movie scenes, and thus, the Millennium Falcon was given its unique and ominous sounds.
Undaunted by the need for a proprietary algorithm and the fact that Twitter wasn’t founded until 2006, a group of military historians were able to dig up these tweets under the third ‘O’ of the HOLLYWOOD sign (just above WATM’s headquarters) after receiving a tip from the ghost of Jimmy Stewart in the American Legion Post 43’s men’s room. Like all important artifacts, these 9 tweets shed light on history (in this case in 140 characters or less):
After the US downed a Syrian jet making a bombing run on US-backed forces fighting ISIS, Russia threatened to target US and US-led coalition planes West of the Euphrates river in Syria.
But while Russia has some advanced surface-to-air missile systems and very agile fighter aircraft in Syria, it wouldn’t fare well in what would be a short, brutal air war against the US.
The US keeps an aircraft carrier with dozens of F/A-18E fighters aboard in the Mediterranean about all the time and hundreds of F-15s and F-16s scattered around Turkey, Qatar, and Jordan.
According to Omar Lamrani, a senior military analyst at Stratfor, a geopolitical analysis firm, Russia has “about 25 planes, only about ten of which are dedicated to air superiority (Su-35s and Su-30s), and against that they’ll have to face fifth-gen stealth fighters, dozens of strike fighters, F-15s, F-16s, as well as B-1 and B-52 bombers. And of course the vast US Navy and pretty much hundreds of Tomahawks.”
“Russians have a lot of air defenses, they’re not exactly defenseless by any means,” Lamrani told Business Insider, “But the US has very heavy air superiority.” Even though individual Russian platforms come close to matching, and in some ways exceed the capability of US jets, it comes down to numbers.
So if Russia did follow through with its threat, and target a US aircraft that did not back down West of the Euphrates in Syria, and somehow managed to shoot it down, then what?
“The US coalition is very cautious,” said Lamrani. “The whole US coalition is on edge for any moves from Russia at this point.”
Lamrani also said that while F/A-18Es are more visible and doing most of the work, the US keeps a buffer of F-22 stealth jets between its forces and Russia’s. If Russia did somehow manage to shoot down a US or US-led coalition plane, a US stealth jet would probably return fire before it ever reached the base.
At that point the Russians would have a moment to think very critically if they wanted to engage with the full might of the US Air Force after the eye-for-an-eye shoot downs.
If US surveillance detected a mass mobilization of Russian jets in response to the back-and-forth, the US wouldn’t just wait politely for Russians to get their planes in the sky so they can fight back.
Instead, a giant salvo of cruise missiles would pour in from the USS George H. W. Bush carrier strike group, much like the April 7 strike on Syria’s Sharyat air base. But this time, the missiles would have to saturate and defeat Russia’s missile defenses first, which they could do by sheer numbers if not using electronic attack craft.
Then, after neutering Russia’s defenses, the ships could target the air base, not only destroying planes on the ground but also tearing up the runways, so no planes could take off. At this point US and Coalition aircraft would have free reign to pass overhead and completely devastate Russian forces.
Russia would likely manage to score a couple intercepts and even shoot down some US assets, but overall the Russian contingent in Syria cannot stand up to the US, let alone the entire coalition of nations fighting ISIS.
Russia also has a strong Navy that could target US air bases in the region, but that would require Russia to fire on Turkey, Jordan, and Qatar, which would be politically and technically difficult for them.
This scenario of a hypothetical air war is exceedingly unlikely. Russia knows the numbers are against them and it would “not [be] so easy for the Russians to decide to shoot down a US aircraft,” according to Lamrani.
And Russia wouldn’t risk so much over Syria, which is not an existential defense interest for them, but a foreign adventure to distract from Russia’s stalled economy and social problems, according to Anna Borshchevskaya, an expert on Russia’s foreign policy in the Middle East at the Washington Institute for Near East Policy.
“Russia is not a great power by most measures, like GDP, population, living standard,” Borshchevskaya told Business Insider. “Russia has steadily declined. It’s still a nuclear power, but not world power.”
In Syria, “a lot of what Putin is doing is about domestic policies,” said Borshchevskaya, and to have many Russian servicemen killed in a battle with a US-led coalition fighting ISIS wouldn’t serve his purposes domestically or abroad.
Bullets, frags, and a bayonet are just a few pieces of heavy gear infantrymen haul on patrol while in a combat zone. But there’s one thing that most grunts carry with them that is equally as important and essential — the Rip It!
Yes, the freakin’ energy drink!
Rip It has been a military staple for years because of these five epic reasons.
A grunt typically carries 80 – 150 pounds of gear when they’re hunting down the bad guys. So the last thing anyone wants to haul is a bulky energy drink can in their cargo pocket. Rip It comes in 8 fluid ounce cans for easy storage.
How awesome is that, right?
Go ahead, take a moment to look at their beauty.
2. Increased physical performance
Ground pounders need to be as athletic as possible when they’re running from compound-to-compound taking down ISIS fighters. Rip It comes with Vitamin C, Guarana Seed Extract, and a sh*t ton of caffeine to make any infantryman extra motivated while they’re kicking down doors.
3. You get mad focus
There’s nothing more important to a grunts than mental focus while engaging targets. The super-charged energy drink will have anyone grunt seeing through ISIS’ lies and their fortified position in no time (experiences may vary, but you’re pretty damn focused).
4. They’re freakin’ delicious
Although drinking water is critical, that sh*t can get boring real quick. Rip It comes in a variety of flavors like “3-way,” “G-Force,” and the “Bomb.” Each flavor could be paired nicely with your favorite MRE. That’s what we call good eatin’.
From personal experience, the enemy often becomes terrified of their American enemy when aggressively pursued. Rip It is commonly used as a pre-workout drink for when infantrymen are looking to get those deployment gains.
A jacked Marine or soldier going up against a skinny ISIS fighter = easy freakin’ day.
William the Conqueror defeated King Harold in the Battle of Hastings in 1066, changing the way Englishmen would speak — and cuss — for all of time.
Before the war William was the Duke of Normandy, the area of western France that the Allies would invade almost 900 years later to defeat the Nazis. William had ambitions beyond the continent though, and sought out an audience with King Edward the Confessor of England. Edward had no children and no obvious heir.
William claimed that Edward promised him the throne during this conversation in 1060, but on his deathbed Edward named an English noble as his successor. Harold Godwine ascended to the throne in 1066 but William immediately called bull-scheisse and contested Harold’s claim.
For obvious reasons, Harold wasn’t eager to give up his throne. So William crossed the English channel with 7,000 soldiers. Harold had just finished fighting off a Norwegian invasion and was forced to face this new threat with a diminished number of troops.
The Normans marched to London and William was crowned king. Once he ascended, William declared French, his native language, the official language of the court. This left the Germanic language spoken by the Anglo-Saxons, Old English, as a “lower” language.
According to the Oxford Dictionary blog, this created a two-tiered language that evolved into modern English. Words for things connected to the ruling class, like large homes and prepared meat, drew from French. So noblemen lived in mansions and ate buef (beef)and porc (pork), while an Anglo-Saxon lived in hus (houses) and raised cus (cows) and picg (pigs).
When it came to the lowest and most vulgar of words, like those for poop, butts, and sex, the Old English words with German roots, scheisse, arsch, and ficken, became terms of profanity. It shouldn’t be too hard to guess which words those evolved into.
Russia is (by land mass), the largest country in the world. At one point in its history, it was home to the largest army in the world, the largest stockpile of nuclear warheads, and… the largest submarines ever built.
Known to the West as the Typhoon class, and to Russians as “Akula” (shark), these black and red beasts were created as a counter to the American Ohio class, carrying dozens of nuclear-tipped ballistic missiles as a deterrent during the Cold War.
At 574 feet long and 75 feet in breadth, these these 25,000 ton monsters were actually larger and wider than the American vessels they were created to compete with.
Essentially tasked with inflicting a nuclear apocalypse upon the West if the Cold War got hot, the Typhoons were given a fairly unique design to keep the boats rugged and survivable — should either an accident or an anti-submarine attack occur — so that they could still carry out their incredibly destructive mission.
Inside the Typhoon’s hulking mass existed a pair of longer pressure hulls from older Delta-class ballistic missile submarines and three more smaller hulls placed around the boat to protect other critical points like engineering spaces and the torpedo rooms. Should a breach occur — whether by collision or attack — the crew inside the other pressure hulls would be safe and the sub would still be operational.
Typhoons carry their missiles in front of their gigantic (and almost comically oversized) sail instead of behind it, as Delta-class and American Ohio-class boats do.
Two nuclear reactors give these warships the power they need to operate, allowing for a maximum speed of around 27 knots underwater (31 mph).
Instead of constantly traversing the world’s oceans, Typhoons were built to sit under the Arctic Circle for months at a time, waiting to punch through the ice in order to launch their deadly payloads of nuclear-tipped missiles.
Because of their designated operating locations, these subs could often escape harassment by American and British hunter/killer submarines constantly prowling around the Atlantic Ocean looking for Soviet warships to mess with.
Because of the length and duration of their missions, Typhoons were designed with crew comfort in mind. In fact, the accommodations aboard a Typhoon were so luxurious that sailors in the Soviet (and later, Russian) navy nicknamed these gargantuan vessels “floating Hiltons.”
Instead of utilitarian steel furniture with minimal padding, a Typhoon’s interior features wooden-paneled walls, comfortable padded chairs, raised ceilings and full-sized doorways, and a fully-stocked gym. Unlike any other submarine ever built, each Typhoon also came with a unique and somewhat enviable feature – a lounge for sailors, including a swimming pool and a sauna.
You didn’t misread that – Typhoons were actually built with small two-foot-deep swimming pools to improve crew morale on long deployments, along with saunas and a lounge area with plush rocking chairs. Televisions (a luxury in the Soviet Navy) were also set up throughout the boat, playing Soviet movies, television shows and propaganda for the crew’s entertainment.
But just as these behemoth war machines entered service with the Soviet Navy, their time rapidly began to wind down. Of the seven planned Typhoons, six were built throughout the 1980s and retired less than 10 years later in the 1990s.
The Russian government simply couldn’t afford to keep fielding the largest missile submarines they (or any other country in the world) had ever built.
In the 1990s, the US and Canadian governments began offering financial incentives to Russia, after the fall of the Soviet Union, to retire a number of their nuclear deterrent warships. Among the many sent to the wreckers were three of the six Typhoons, with the other three staying in service.
Today, only one Typhoon remains active while two others have been placed in reserve. The sole active sub, the Dmitriy Donskoy, serves as a test platform for Russia’s newest submarine-launched cruise missiles, though its days are also numbered with the advent of newer Russian Borei-class ballistic missile subs.
The other two Typhoons currently held in reserve — the Arkhangelsk and the Severstal — will likely be scrapped between 2018 and 2019, with the Donskoy following not too long after, ending the story of the largest nuclear ballistic missile submarines ever built.
According to Marine Corps spokesman Capt. Sam Stephenson, injury prevention is a major force behind the change.Advertisement
“Research has shown that crunches with the feet restrained require significant hip flexor activation,” Stephenson explained in a statement.
“This has been linked to an increased risk of injury, including lower back pain,” he added.
Marines will be expected to perform a forearm plank – an exercise where the body is held in a push-up-like position while being supported by the forearms, elbows, and toes.
Additionally, the plank has “numerous advantages as an abdominal exercise,” according to the Marines. The exercise “activates almost twice as many muscles as the crunch and has been proven to be most reliable in measuring the true endurance required for daily activity function,” Stephenson said.
The changes announced Thursday also tweak the minimum and maximum times for the plank exercise. The maximum time will go from 4:20 to 3:45, while the minimum will change from 1:03 to 1:10. This change will take effect in 2022.
The Marines said its “human performance policies and standards are in a constant state of analysis, assessment, and modification, if necessary, to ensure that they best support the overall readiness of the force” in a message announcing the new standards.
