MIGHTY HISTORY

This airman gave his life to rescue soldiers from a massive firefight

The Air Force Pararescue community lives according to the motto, “These Things We Do, That Others May Live.” There may be none who lived that motto more fully than Airman 1st Class William Pitsenbarger who was killed in action in March, 1966, after intentionally placing himself in harm’s way to rescue infantryman pinned down by snipers, mortars, and machine gun fire.

For his valor, he became the first enlisted airman to receive the Medal of Honor.

A1C William Pitsenbarger

Pitsenbarger, or “Pits,” as he was known, first tried to join the military as a Green Beret when he was 17, but his parents prevailed upon him to wait until after high school. In 1962, he became a graduate and answered the call — this time, with the Air Force instead of the Army. As a pararescuemen, he would be responsible for grabbing downed airmen and others from contested and enemy-held areas around the world. Becoming a PJ was no easy feat, and it wasn’t a job for the timid.

After completing SCUBA training with the Navy, paratrooper training with the Army, and survival and medical training with the Air Force, he was ready to go to work. Before his deployment to Vietnam, he was called upon to help rescue two hunters stuck in the California wilderness. After rappelling down a sheer cliff face to reach them, he and another pararescueman encountered an angry bear. Pits charged the bear, yelling and screaming, chasing it off. It was immediately clear that he was cut out for this kind of work.

Pitsenbarger finally got orders overseas — to Okinawa, Japan. Wanting to go where his help was needed most, he requested to go to Vietnam instead, and his request was approved. Before shipping out, his parents later said that they were sure they would never see him alive again. Sadly, they were right.

In Vietnam, Pits proved himself an exceptionally capable medical and rescue professional. He helped treat lepers at a colony in Vietnam, escorted singer Mary Martin during a USO tour, and inserted into a burning minefield to rescue a South Vietnamese soldier who had lost a foot trying to stomp out a grass fire. For the minefield rescue, Pitsenbarger was awarded the Airman’s Medal.

But Pitsenbarger’s most consequential moments came in 1966. On April 11, three companies of the Big Red One, the Army’s 1st Infantry Division, were engaged in a risky sweep across two provinces in search of Viet Cong units. Charlie Company was on one end of the formation and realized too late that it had drifted from the others — and was exposed to sniper fire.

Company leadership realized they were in danger and set up a defensive perimeter, but they were already outnumbered and surrounded. The North Vietnamese triggered their attack, sending mortar and sniper fire ripping through the American formation. The other companies attempted to come to their aid, but mounting casualties quickly made it clear that Charlie Company needed a rescue.

The Air Force sent two rescue helicopters to begin getting the wounded out. The first flight was challenging but, for a jungle firefight in Vietnam, fairly uneventful. Both helicopters took the first flight of wounded to a nearby hospital and doubled back for more. Once back in the field, it became clear to Pits that the Army soldiers no longer had the manpower necessary to hold back the attacks, treat the wounded, and put them on litters for extraction. He volunteered to insert into the jungle and help out.

The pilot reluctantly agreed to the risky request, and Pits began sending men up to the two helicopters despite bursts of fierce mortar and machine gun fire. Pitsenbarger was responsible for getting nine wounded men out in three flights, refusing his own extraction each time, before ground fire nearly downed one of the helicopters and forced them to leave.

On the ground, Pits continuously exposed himself to enemy fire to recover rifles and ammunition from the dead to redistribute to the living. He was wounded at least twice before he reached his final position. He had given away his pistol to a soldier too wounded to use any other weapon, and so Pits used one of the recovered rifles to resist a North Vietnamese advance until he was hit again — this time fatally.

The Army fought on through the night, relying on danger close artillery and airstrikes to survive the night. When the Air Force was able to get rescue helicopters back in the next morning, an Army captain told the next pararescueman on the ground what had happened to Pits.

Charlie Company had 134 men when the battle started. 106 of them were wounded or killed in the fighting, but Pits had gotten an extra nine of them out and kept others alive overnight.

Five months later, on Sept. 22, 1966, the Air Force presented the Air Force Cross to Pitsenbarger’s parents. It was the first awarding of the Air Force Cross to an enlisted airman for service in Vietnam. After decades of campaigning from the men he saved from what seemed like certain demise, Pitsenbarger’s citation was finally upgraded to the Medal of Honor. Pitsenbarger is the first enlisted airman to receive such an award.

Now, Pits’ story is headed to the big screen. The Last Full Measure is scheduled to release on Jan. 24, 2020. Be sure to watch the trailer below and secure your tickets to honor this true American hero.

China says it has a one-shot kill against US warships

China is showcasing its powerful new hypersonic anti-ship cruise missile, which could raise the stakes as tensions flare between China’s military and the US Navy.

China Aerospace Science and Industry Corporation (CASIC) unveiled the CM-401 short-range anti-ship ballistic missile at Airshow China in Zhuhai, the country’s largest military and commercial aviation exhibition.


“The system is intended for rapid and precision strikes against medium-size ships, naval task forces, and offshore facilities,” a CASIC representative told IHS Jane’s Defence Weekly.

The Chinese state-affiliated Global Times, citing a press release from the company that produced the weapon, reported that the missile can travel at speeds roughly six times the speed of sound.

The speed and unpredictable flight patterns made possible through mid-flight changes to the trajectory make the missile much more difficult, if not impossible, to intercept.

The CM-401s are assumed to fly on a “skip-glide trajectory,” The War Zone reported, citing graphics detailing the capabilities of the new system.

“The weapon has the potential of destroying a hostile vessel with one hit,” the paper reported, citing a Chinese military expert. The CM-401 is believed to include an independent phased array radar in the nose for terminal targeting.

The missile, which has a maximum range of 180 miles, can be launched from a shore-based launcher or from a ship-based launch-canister. The Chinese People’s Liberation Army Navy’s new Type 055 destroyers could potentially carry the CM-401 missiles, The National Interest reported, although it is possible the vessel will carry a longer-range variant.”The country will possess greater deterrence against hostile sea attacks, especially from large vessels like aircraft carriers,” a military expert told the Global Times.

Other Chinese anti-ship systems include the DF-21D and DF-26 ballistic missiles, as well as the YJ-12 and YJ-18 supersonic anti-ship cruise missile and a handful of subsonic cruise missiles. The development of a hypersonic strike platform represents a potentially-alarming advancement in stand-off anti-access, area-denial (A2/AD) technology, a consistent challenge for the US military.

In September 2018, the US Navy had a tense encounter with the PLAN when a Chinese warship challenged a US destroyer in the South China Sea. US and Chinese military officials anticipate additional confrontations in the future.

Trump reportedly thought N. Korea would ‘pull out’ — so he beat them to it

President Donald Trump took North Korea’s recent provocative statements into account when he canceled his planned summit with the country’s leader Kim Jong Un. Trump believed Kim would cancel the meeting first, US officials said, according to NBC News.

“There was no hint of this yesterday,” a US official familiar with the summit preparations told NBC News on May 25, 2018.


Trump reportedly began seriously considering withdrawing from the summit on May 23, 2018, and consulted with Vice President Mike Pence, secretary of state Mike Pompeo, chief of staff John Kelly, and national security adviser John Bolton. The president also spoke with defense secretary Jim Mattis on May 24, 2018.

Trump eventually released a letter addressed to Kim on May 24, 2018, citing what he described as Pyongyang’s “tremendous anger and open hostility” in its recent public statements. North Korea sent out heated missives in response to controversial remarks from Pence and Bolton on the fate of the North Korean regime.

According to a Washington Post report, Trump was reportedly worried that North Korea would back out of the meeting first, and in an effort to prevent the US from looking desperate, he beat them to the punch.

“I was very much looking foward to being there with you,” Trump said in the letter.

Trump’s abrupt decision took lawmakers and allies, including South Korean President Moon Jae-in, by surprise. It also contradicted a letter from the State Department on the constructive talks Pompeo was having with other Asian leaders ahead of the summit, which was sent nearly two hours before Trump’s letter to Kim.

Pompeo has taken a prime role in US-North Korean diplomatic relations, after he traveled to North Korea and helped secure the release of three Korean-American prisoners. But according to some US officials, Bolton, who is viewed as a hawkish policy advisor, clashed with some of Pompeo’s ideas and floated the notion of scuttling the Trump-Kim meeting.

Following Trump’s decision, North Korean officials released a statement saying they were still willing to meet with the US to “resolve issues anytime and in any format.”

“I want to conclude that President Trump’s stance on the North-US summit does not meet the world’s desire for peace and stability both in the world and on the Korean Peninsula,” a North Korean official said.

Why Russian submarines are causing alarm all over the world

Russian undersea naval activity in the North Atlantic has reached new levels, and NATO is worried that the undersea cables connecting North America and Europe and the rest of the world are being targeted.


“We are now seeing Russian underwater activity in the vicinity of undersea cables that I don’t believe we have ever seen,” US Navy Rear Adm. Andrew Lennon, commander of NATO’s submarine forces, told The Washington Post. “Russia is clearly taking an interest in NATO and NATO nations’ undersea infrastructure.”

Moscow’s subs appear to be interested in the privately owned lines that stretch across the seabed, carrying insulated fiber-optic cables. The cables are strewn across the world’s oceans and seas, carrying 95% of communications and over $10 trillion in daily transactions.

Blocking the flow of information through them could scramble the internet, while tapping into them could give eavesdroppers a valuable picture of the data flowing within. The cables are fragile and have been damaged in the past by ships’ anchors, though usually in areas where repairs are relatively easy.

Air Chief Marshal Stuart Peach, the UK’s defense chief, has also sounded alarm about Russia’s apparent focus on the undersea cables. “There is a new risk to our way of life, which is the vulnerability of the cables that criss-cross the seabeds,” he said earlier this month.

Lennon’s and Peach’s warnings are only the latest about Russian undersea activity in the vicinity of important underwater infrastructure.

The New York Times reported in late 2015 that increased Russian naval activity near the lines led US military officials to fear Moscow planned to attack the cables in the event of conflict. US officials said they had seen elevated Russian operations along the cables’ routes in the North Sea and Northeast Asia and even along US shores.

Many undersea cables are in familiar places, but others, commissioned by the US for military purposes, are in secret locations. US officials said in 2015 that increased Russia undersea activity could have been efforts to locate those cables.

There was no sign at that time that any cables had been cut, and Lennon declined to tell The Post if the defense bloc believed Russia has touched any of the undersea lines.

But elevated Russian undersea activity comes as NATO members and other countries in Europe grow more concerned about what they see as assertive Russian activity on the ground, in the air, and at sea around the continent.

Russian planes have had numerous near-misses with their NATO counterparts over the Baltics in recent months, and Russia’s massive Zapad 2017 military exercises in Russia and Belarus during September had NATO on edge.

A force multiplier

Moscow has also pursued naval expansion, with a focus on undersea capabilities. A modernization program announced in 2011 directed more money toward submarines, producing quieter, more lethal designs. Moscow has brought online or overhauled 13 subs since 2014, according to The Post.

Among them was the Krasnodar, which Russian officials boasted could avoid the West’s most sophisticated radars. US and NATO ships tracked the Krasnodar intently this summer, as it traveled from Russia to the Black Sea, stopping along the way to fire missiles into Syria. More advanced subs are reportedly in production.

Subs are seen by Moscow as a force multiplier, as rivals would need to dedicate considerable resources to tracking just one submarine.

Subs are also able to operate without being seen, to carry out retaliatory strikes, and to threaten resupply routes, allowing them to have an outsize impact.

Russia now fields 60 full-size subs, while the US has 66, according to The Post.

Adding to Russia’s subsurface fleet are deep-sea research vessels, including a converted ballistic missile sub that can launch smaller submarines.

“We know that these auxiliary submarines are designed to work on the ocean floor, and they’re transported by the mother ship, and we believe they may be equipped to manipulate objects on the ocean floor,” Lennon told The Post.

 

Russian officials have also touted their fleet’s increased operations.

In March 2017, Adm. Vladimir Korolev, commander of the Russian navy, said the Russian navy in 2016 “reached the same level as before the post-Soviet period, in terms of running hours.”

“This is more than 3,000 days at sea for the Russian submarine fleet,” Korolev added. “This is an excellent sign.”

‘Those ships are vulnerable to undersea threats’

Western countries have also pursued their own buildup in response.

While US plans call for curtailing production of Virginia-class attack subs when Columbia-class missile subs begin production in the early 2020s, a recent study found that the Navy and industry can produce two Virginia-class subs and one Columbia-class sub a year — averting what Navy officials have described as an expected submarine shortfall in the mid-2020s and keeping the fleet ahead of near-peer rivals like Russia and China.

The US is looking to sensors, sonar, weapons control, quieting technologies, undersea drones, and communications systems to help its subs maintain their edge. (Government auditors have said the Columbia-class subs will need more testing and development to avoid delays and cost overruns down the line, however.)

Elsewhere in NATO, Norway and Germany — the latter of which does not currently have any operational subs — recently agreed on a deal to build two submarines for each country.

The response extends to tactics as well. US and NATO personnel have dedicated more time to anti-submarine-warfare training and operations. Transponder data shows that the US Navy has in recent months flown numerous sorties over areas where Russian subs operate, according to The Post.

“It is an indication of the changing dynamic in the world that a skill set, maybe we didn’t spend a lot of time on in the last 15 years, is coming back,” Capt. Jim McCall, commander of the air wing on aircraft carrier USS George H.W. Bush, told The Wall Street Journal this fall.

As the number of sub-hunting ships that can patrol the North Atlantic, Baltic, and Mediterranean has fallen since the Cold War, NATO members are working to deploy more air and sea assets. This summer, France, Germany, Greece, Italy, Spain, and Turkey signed a letterof intent to start development of new submarine-detecting aircraft.

The number of frigates — typically used for anti-submarine warfare — in use by NATO allies has fallen from about 100 in the early 1990s to about 50 today, prompting the US to rush to field more in the coming years.

Attention has also returned to the North Atlantic choke point between Greenland, Iceland, and the UK. The GIUK Gap was a crucial element of Cold War naval defenses, and US anti-submarine planes were based in Iceland for decades before leaving in 2006.

The US Navy has been upgrading hangers in Iceland to accommodate new P-8A Poseidon aircraft, however, and the Pentagon has said the US and Iceland have agreed to increase rotations of the US surveillance planes there next year.

As the Russian navy seeks to reverse the contraction it experienced after the Cold War, NATO too is looking to expand its commands after shrinking in the years since the fall of the Soviet Union.

A recent NATO internal report found that the alliance’s rapid-response abilities had “atrophied since the end of the Cold War” and recommended setting up two new commands to streamline supply efforts.

One, based on the continent, would oversee the movement of personnel and material in Europe, and the other, potentially based in the US, would oversee transatlantic resupply efforts and the defense of sea lanes.

“If you want to transport a lot of stuff, you have to do that by ship,” Lennon, NATO’s submarine commander, told The Journal this fall. “And those ships are vulnerable to undersea threats.”

Plans for the new commands were approved in early November. More details are expected in February, though current plans include embedding the NATO North Atlantic command with US Fleet Forces Command in Norfolk, Virginia.

“We are a transatlantic alliance, and we must therefore be in a position to transport troops and equipment over the Atlantic,” NATO Secretary General Jens Stoltenberg said recently. “For that we need secure and open seaways.”

US Navy expects there will probably be ‘hundreds’ of coronavirus cases aboard the aircraft carrier USS Theodore Roosevelt

The acting secretary of the Navy said Thursday that he suspects the number of coronavirus cases aboard the aircraft carrier USS Theodore Roosevelt will eventually be “in the hundreds.”

The first coronavirus cases aboard the flattop were reported Tuesday of last week. At that time, there were only three cases. The number had climbed to 114 by Thursday.

“I can tell you with great certainty there’s going to be more. It will probably be in the hundreds,” Thomas Modly, the acting Navy secretary, told reporters at the Pentagon Thursday afternoon.

He said that none of the 114 that have tested positive had been hospitalized. “The ones that are sick are exhibiting mild or moderate flu symptoms. Some are exhibiting no symptoms. And, some have already recovered,” he said.

The ship is currently in Guam, where the Navy is in the process of removing thousands of sailors from the ship and testing the entire crew.

On Wednesday, Modly told reporters 1,273 sailors, roughly one-fourth of the crew, had been tested. At least 93 tests had come back positive.

The Navy is moving at least 2,700 sailors off the ship, and those who test negative will be put up in vacant hotels on Guam, where they will be quarantined for two weeks.

Before the outbreak, the massive flattop had been sailing the Pacific. In early March, the ship made a port call in Da Nang, Vietnam.

Modly’s prediction that the number of coronavirus cases aboard the carrier could eventually be in the hundreds came as he announced that he had relieved the USS Theodore Roosevelt’s commanding officer of duty due to a loss of trust and confidence.

Capt. Brett Crozier, the ship’s CO, wrote a letter warning that “the spread of the disease is ongoing and accelerating.” He called for the removal of the majority of the crew from the ship as soon as possible. “Sailors do not need to die,” he wrote.

The letter leaked to the San Francisco Chronicle and then quickly made headlines everywhere.

The acting Navy secretary accused the CO of mishandling information by distributing the letter outside the chain of command in a way that made it susceptible to being leaked. He said that Crozier exercised “poor judgment” and that his letter caused unnecessary panic among sailors and military families.

“I have no doubt in my mind that Capt. Crozier did what he thought was in the best interest and well-being of his crew,” Modly said. “Unfortunately, it did the opposite.”

Everything you want to know about that black hole

A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). EHT is an international collaboration whose support in the U.S. includes the National Science Foundation.

A black hole is an extremely dense object from which no light can escape. Anything that comes within a black hole’s “event horizon,” its point of no return, will be consumed, never to re-emerge, because of the black hole’s unimaginably strong gravity. By its very nature, a black hole cannot be seen, but the hot disk of material that encircles it shines bright. Against a bright backdrop, such as this disk, a black hole appears to cast a shadow.

The stunning new image shows the shadow of the supermassive black hole in the center of Messier 87 (M87), an elliptical galaxy some 55 million light-years from Earth. This black hole is 6.5 billion times the mass of the Sun. Catching its shadow involved eight ground-based radio telescopes around the globe, operating together as if they were one telescope the size of our entire planet.


“This is an amazing accomplishment by the EHT team,” said Paul Hertz, director of the astrophysics division at NASA Headquarters in Washington. “Years ago, we thought we would have to build a very large space telescope to image a black hole. By getting radio telescopes around the world to work in concert like one instrument, the EHT team achieved this, decades ahead of time.”

To complement the EHT findings, several NASA spacecraft were part of a large effort, coordinated by the EHT’s Multiwavelength Working Group, to observe the black hole using different wavelengths of light. As part of this effort, NASA’s Chandra X-ray Observatory, Nuclear Spectroscopic Telescope Array (NuSTAR) and Neil Gehrels Swift Observatory space telescope missions, all attuned to different varieties of X-ray light, turned their gaze to the M87 black hole around the same time as the EHT in April 2017. NASA’s Fermi Gamma-ray Space Telescope was also watching for changes in gamma-ray light from M87 during the EHT observations. If EHT observed changes in the structure of the black hole’s environment, data from these missions and other telescopes could be used to help figure out what was going on.

While NASA observations did not directly trace out the historic image, astronomers used data from NASA’s Chandra and NuSTAR satellites to measure the X-ray brightness of M87’s jet. Scientists used this information to compare their models of the jet and disk around the black hole with the EHT observations. Other insights may come as researchers continue to pore over these data.

There are many remaining questions about black holes that the coordinated NASA observations may help answer. Mysteries linger about why particles get such a huge energy boost around black holes, forming dramatic jets that surge away from the poles of black holes at nearly the speed of light. When material falls into the black hole, where does the energy go?

“X-rays help us connect what’s happening to the particles near the event horizon with what we can measure with our telescopes,” said Joey Neilsen, an astronomer at Villanova University in Pennsylvania, who led the Chandra and NuSTAR analysis on behalf of the EHT’s Multiwavelength Working Group.

NASA space telescopes have previously studied a jet extending more than 1,000 light-years away from the center of M87. The jet is made of particles traveling near the speed of light, shooting out at high energies from close to the event horizon. The EHT was designed in part to study the origin of this jet and others like it. A blob of matter in the jet called HST-1, discovered by Hubble astronomers in 1999, has undergone a mysterious cycle of brightening and dimming.

Chandra, NuSTAR, Swift and Fermi, as well as NASA’s Neutron star Interior Composition Explorer (NICER) experiment on the International Space Station, also looked at the black hole at the center of our own Milky Way galaxy, called Sagittarius A*, in coordination with EHT.

Getting so many different telescopes on the ground and in space to all look toward the same celestial object is a huge undertaking in and of itself, scientists emphasize.

“Scheduling all of these coordinated observations was a really hard problem for both the EHT and the Chandra and NuSTAR mission planners,” Neilsen said. “They did really incredible work to get us the data that we have, and we’re exceedingly grateful.”

Neilsen and colleagues who were part of the coordinated observations will be working on dissecting the entire spectrum of light coming from the M87 black hole, all the way from low-energy radio waves to high-energy gamma rays. With so much data from EHT and other telescopes, scientists may have years of discoveries ahead.

This colorized German war footage shows why Stalingrad was hell on Earth

It was the pivotal battle that most historians believe turned the tide against the Nazis for good in World War II, resulting in a cascade of defeats as the Wehrmacht beat its retreat to Germany from the Soviet Eastern Front.


But it wasn’t always that way, and in the opening months of Operation Barbarossa the German army seemed poised for a stunning victory against the Red Army.

As part of its push to secure the southern Caucasian oil fields, the German 6th Army was ordered to take the city of Stalingrad in September 1942, a move some historians believe was strategically irrelevant, as the Nazis were already well on their way to Baku.

But many believe Adolf Hitler wanted to capture the city as a thumb in the eye to Soviet leader Josef Stalin, for whom the city was renamed.

Initially, the German army was able to push well into the city, taking the Univermag department store at its center. But the Red Army dug into the city’s industrial areas along the banks of the Volga river and the battle ground down into a brutal street-by-street slugfest.

One of the Red Army’s most accomplished generals, Marshall Georgi Zhukov, hatched a plan to surround the 6th Army and cut off its supply lines. And by mid-November, the Soviets began to squeeze the Nazis inside the city.

As winter descended, the Germans were running out of food, ammunition and other supplies, and when a rescue mission launched by Field Marshall Erich Von Manstein failed to break through, the Nazis’ fate was sealed. The German forces under the command of Gen. Friedrich Paulus eventually surrendered in early February 1943.

It was a horrific battle waged on a titanic scale in a battlefield unlike any seen in modern times. In all, the Germans lost about 147,000 men in the battle while surrendering 91,000. The Soviets took even more catastrophic losses, with 480,000 dead and 650,000 wounded. An estimated 40,000 civilians were killed in the fighting.

China’s biggest new enemy in the Pacific will surprise you

China’s growing influence in the Asia-Pacific region has made some of its neighbors uneasy, and many are making political and military efforts to counter what they see as a potential threat.

An unofficial report from the Five Eyes intelligence partnership, made up of the UK, US, Canada, New Zealand, and Australia, recently warned about what it saw as “a concerted foreign interference campaign” from China against New Zealand.

The current government in Wellington has denied any tension with its Five Eyes partners, and its latest Strategic Defense Policy statement, released in July 2018 by Defense Minister Ron Mark, puts the perceived challenges posed by Beijing in clear language.


“New Zealand is navigating an increasingly complex and dynamic international security environment, and will also face compounding challenges of a scope and magnitude not previously seen in our neighbourhood,” the document says.

New Zealand’s leaders have in the past shied away from directly naming China when discussing tensions in the region, but the statement makes explicit criticisms of China, saying that even as Beijing has benefited from the international rules-based order and sought greater economic interconnectedness, “it has not consistently adopted the governance and values championed by the [international] order’s traditional leaders.”

China, it says, “holds views on human rights and freedom of information that stand in contrast to those that prevail in New Zealand.”

Beijing wants to “restore claimed historical levels of influence in its periphery” and take “an enhanced global leadership role,” it adds. In Asia, “China’s more confident assertion of its interests has at times raised tensions with neighbouring states and with the United States.”

China’s growing military power raises the costs of acting against its interests, and Beijing also “has determined not to engage with an international tribunal ruling on the status of sovereignty claims,” the statement says, likely referring to a 2016 international-court ruling that rejected China’s expansive claims in the South China Sea.

The paper cites other challenges, such as illiberal approaches to the international order taken by countries like Russia and Saudi Arabia, internal concerns about national-security and political and demographic shifts in Western democracies, and global sources of disorder like terrorism, climate change, and cyber threats.

Uncertainty about the US’s future international role “has disruptive implications in itself,” the statement says. And amid increasing competition between world powers, “complex transnational threats will disrupt New Zealand’s neighbourhood in ways not previously seen.”

When presenting the document, Mark said it would not surprise China, which he said would respect New Zealand’s “forthrightness.” In the days since, however, Beijing has responded severely.

Chinese Foreign Ministry spokeswoman Hua Chunying said July 9, 2018, that Beijing “lodged stern representations” with Wellington over the latter’s “wrong remarks.”

“We urge New Zealand to view the relevant issue in an objective way, correct its wrong words and deeds and contribute more to the mutual trust and cooperation between our two countries,” she said.

Winston Peters, New Zealand’s foreign minister, also said on July 9, 2018, that China had expressed concern over the paper through its ambassador in Wellington and to New Zealand’s ambassador in Beijing, but he downplayed the response and said his government would not change course.

“We’re not here to make people happy,” he said. “We’re here to be a responsible international citizen.”

“New Zealand’s position had firmed up,” Robert Alyson, a professor at Victoria University’s Center for Strategic Studies, told The Wall Street Journal. “It’s more willing to say things about China that are a bit critical.”

New Zealand’s response to China’s growing presence is not been limited to words.

Days after announcing the new defense statement, the government there approved the nearly id=”listicle-2586055515″.5 billion purchase of four P-8A Poseidon maritime patrol aircraft, which are made by Boeing and are in use by a number of allies, including Australia and the UK. South Korea also recently said it would purchase several Poseidons.

The purchase in Wellington’s biggest military buy in decades, and the planes will give the island nation enhanced patrol and intelligence-gathering capability — as well as an advanced sub hunter— at a time when China’s growing submarine fleet is worrying its neighbors.

Wellington got rid of its combat aircraft at the beginning of this century, and the fleet of aging P-3 Orion patrol aircraft that the Poseidons will replace have seen their maintenance costs spike over the past decade. The Defense Ministry has said the Orions would need to be replaced by the mid-2020s. The Poseidons are to start operations in 2023.

“This decision strengthens the coalition government’s Pacific reset by providing a maritime patrol capability with the significant range and endurance needed to assist our partners in the region,” Mark said.

This NBA star talked about what made his USO tour so memorable

Ray Allen, a 10-time NBA All-Star, recently participated in a USO holiday tour with Chairman of the Joint Chiefs of Staff Gen. Joseph Dunford. On this tour, the athlete, along with other celebrities, visited service members in Turkey, Qatar, Afghanistan, and Germany.


Now back in the states, Allen has spoken about much the trip meant to him, both as the son of an Air Force metals technologist and as a retired athlete.

One of the topics Allen touched on during an interview with Sports Illustrated was the way military terms pop up in sports discussions, even though they don’t really fit:

In the NBA, often times we’ll be in the locker room and we’ll talk about “going to war” and “going into battle” and “being in the foxhole,” all these terminologies that we equate with being at war. I have such a greater appreciation for the conflicts going on around the world, now I try to not use those terms out of respect.

Allen also told SI about how a comment from Dunford helped him appreciate the military’s expeditionary mindset, and how service members are constantly working to make sure that conflicts rarely come to American shores:

One of the things that General Dunford said that resonated with me was, “We’re over here at war, my job is to make sure that we have all away games.” So when I got back on U.S. soil, I thought about how privileged we are.

While speaking to USA Today, the NBA player took a moment to discuss how different life is in a combat zone, but that being there with professional warfighters made him feel safe:
“I (felt) more protected than I’ve ever felt in my life, being on that tour. I had some bad guys with me. Guys who knew how to handle weapons, that had been in combat. I’m looking to my left and right, and I’m like ‘I’m safe, I feel good about where I am, because these guys know what they’re doing.’ And that’s what I want to tell everybody, any athlete, from the NBA to baseball to football…join up with the USO and take a tour. It’ll give you a greater perspective on war, it’ll give you a greater perspective on the people that are fighting the war.”

This mini A-10 Warthog can guard your yard

A remote control airplane hobbyist has modified a model A-10 Thunderbolt II to conduct Nerf strafing runs on T-72 cardboard tanks and uploaded the results to YouTube. The modified, remote control A-10 can fire 12 paper-tank-busting Nerf balls in under half a second. You know, just in case your yard is overrun with mini Soviet tanks.

If you’re really bored, you can make one out of legos, too.

 

The RC A-10 can also fire three darts for taking out hard targets. Though reportedly not made from depleted uranium, the darts have more heft and better ballistic properties than the Nerf rounds, but they’re still loaded into the primary tube. That means backyard commanders have to decide their weapons layouts before the mission. It’s three darts or 12 balls, not both.

Both primary weapon loads of the A-10 are on display in the full video:

The Air Force is continuing to look at potential replacements for the full-sized A-10. It’s original replacement, the F-35A, achieved initial operating capability on Aug. 2, but Congress has pressured the flying service to look into a new attack plane to support ground troops.

Despite its impressive performance against cardboard tanks and low cost, the RC A-10 has a number of drawbacks that will likely prevent its purchase by the Air Force.

First, the RC A-10 is manufactured by an untested contractor, YouTube user ajw61185. More importantly, it fires all of its rounds in a single burst, requiring it to return to its base to rearm after a single pass.

Critics of the RC A-10 point out that it was developed for a very different yard than exists today and claim the platform is simply outdated. Modern yards contain advanced sprinklers that the RC A-10 has no countermeasures with which to defend itself. The more stealthy RC F-35 might be able to avoid many of these sprinklers, but it has yet to reach the fleet due to frequent cost overruns and malfunctions.

Still, the RC A-10 is probably fine for home use and so could be used by defense-minded property owners to deter cross-border actions by stray dogs, squirrels, and other aggressors.

Why only an idiot would render a  salute in a combat zone

It’s inevitable. Someone will get deployed, spot an officer, and render a proper salute as if they were back in the garrison only to be met with a look of disdain. We’ve seen it the other way around, too. A troop walks by an officer who gets offended when they aren’t given a salute.

Now, there’s no denying that it’s good military discipline to give a proper greeting to an officer whenever they cross your path — it shows respect worthy of their rank and position.

But when you’re deployed, the rules are different — and for good reason.

There’s a time and place for a salute. Remember, the respect the salute is meant to convey is more important than the act itself. (U.S. Air Force photo by Senior Airman Cody Miller)

 

First of all, if you actually take the time to read the regulations on saluting, you’ll notice there’s almost always a clause that states “except under combat conditions.” The regulations are very clear about not saluting under combat conditions — but there are other exceptions not explicitly outlined in the books.

It doesn’t make sense to render a salute when you’re in formation and you’ve not been given the command, when you’re carrying things with both hands, or while eating. Saluting in these moments is a great way to turn something respectful into a sign of disrespect.

If you’re going to salute in combat, you’re wrong. If you’re going to salute with a rifle and it doesn’t look like the above photo, you’re even more wrong. (U.S. Navy photo by Mass Communication Specialist 3rd Class Damian Martinez)

 

Anyway, if you’re going to salute in a combat zone, at least do it right. If you’re deployed, chances are high that you’re carrying a rifle with you at all times. Giving a proper salute while carrying a rifle is actually only done when given the command to “present, arms.” Even then, it doesn’t involve putting your right hand to your brow.

But performing that motion requires you to raise the barrel of your rifle into the air. And if there’s even the slightest chance that there’s a round in the chamber (which, especially when you’re in a combat zone, is a possibility), swinging around the rifle is just asking for a negligent discharge…

Yeah. Jokingly saluting an officer and saying “sniper check, sir!” suddenly became a little less funny, huh? (National Archives)

 

Why is all of this important to note? Because you must assume that the enemy is always watching from a distance, ready to take their shot at the highest-ranking person they can. This has been a concern since the first scope was put on a rifle.

While there are many officers who’ve lost their lives to enemy snipers, it’s unclear just how many were killed directly after some moron announced their importance to the rest of the world. What we do know, however, is that the most famous American sniper took out a high-ranking enemy with the help of a salute.

Gunnery Sgt. Hathcock made his legendary shot at an NVA general from over two miles away. He was too far away to accurately tell which enemy was the general at a glance, especially when several people walked in a group. Take a single guess at how he identified who was who.

You can still show respect to officers while deployed without doing it improperly and risking their life. A simple, “Good afternoon, sir,” is much more appreciated.
