The United States dropped more than seven million tons of bombs on Vietnam, Laos, and Cambodia between 1957 and 1975, more than twice what it dropped on Europe and Asia during all of World War II. That’s a lot of ordnance. This doesn’t take into account the rockets, mortars, tank rounds, etc. used by American and allied infantrymen on the ground in Vietnam. An estimated ten percent or more of that tonnage didn’t explode – which means it’s still there.
It also means someone, now nearly 50 years later, is going to find it – a mother, father, or child. That’s where Chuck Searcy, a U.S. Army veteran, comes in. He’s on a mission to clear those UXOs.
Chuck Searcy is a Georgia-based Army vet on a new mission.
Searcy co-founded Project RENEW in 2001, a million effort to clear unexploded weapons from the former war zone while teaching children about the bombs and helping those affected by them.
Since the war’s official end in 1975 – when North Vietnam invaded and forcibly unified the South – more than 100,000 Vietnamese civilians have been killed by unexploded ordnance in the country. Some of them were farmers or other kinds of laborers, clearing paths through fields as they’ve done time and time again. Others injured by the bombs were metal scrappers, gathering what they could to make extra money.
Ten percent is a lot of explosive still sitting around.
In 2017, Searcy and Project RENEW cleared some 17,000 munitions found in the middle of Vietnam. Over the project’s lifetime, the group has cleared more than a million. Searcy first returned to Vietnam in 1995, the year after the United States formally normalized relations with the still-Communist country. Back then, he was helping kids find orthopedic devices for missing limbs, but he kept reading about the problems with explosives in the countryside.
Now they do. When someone finds a bomb and reports it, the group will send out a team to dispose of it as they always have. But in the last 20 years, they’ve become more proactive, more methodical. They not only interview villagers asking about bomb sightings, they examine U.S. Air Force databases, reviewing every single bombing run of the war.
Chuck Searcy now and in his Vietnam-era years.
While often times, the difference can be difficult to measure, there is one important number to follow, and that is how many people were killed or injured by unexploded ordnance in a given area. In Quang Tri, a province that saw some of the heaviest fighting of the Vietnam War, the number killed or wounded in 2001 (when project RENEW began its education program) was 89. In 2017, the number dwindled to two.
This week’s Borne the Battle podcast features Marine Corps veteran Chris Burke and the youngest head coach in NCAA Lacrosse, Mitch Shafer.
Burke discussed his service in the Marines, including his injury and recovery from an IED explosion in Afghanistan. However, Burke’s real story begins on what he did after serving in Afghanistan.
When Burke left service, he went back to school, where he planned on joining the lacrosse program in hopes of playing with his younger brother. But his plans didn’t go the way he had hoped. Instead, he found a new sense of purpose, one that reminded him of the camaraderie that he experienced in the Marines. In time, that new sense of purpose led to Burke accepting the position of defensive coordinator at Maryville University.
Marine Veteran Chris Burke is now mentoring youth as a the defensive coordinator for the Maryville Lacrosse Program.
Now, at Maryville, with Shafer’s help, Burke uses his Marine Corps leadership experience to to mentor and coach his college lacrosse players for more than just on the field. From visiting local VA hospitals to sending care packages overseas, Burke and Shafer lead the lacrosse team in bridging the military-civilian gap.

As the F-35 Joint Strike Fighter program barrels toward its final major testing process before full-rate production, program leaders say a much-discussed comparison test between the beloved A-10 Thunderbolt II and the new 5th-generation fighter is very much still in planning and could kick off as soon as April 2018.
In a roundtable discussion with reporters at the F-35 Joint Program Office headquarters near Washington, D.C., on Feb. 28, the director of the program said the final test and evaluation plan is still being constructed. That will determine, he said, when the A-10 vs. F-35 test begins, and whether it happens in the main test effort or in an earlier, more focused evaluation.
“The Congress has directed the [Defense Department] to do comparison testing, we call it,” Vice Adm. Mat Winter said. “I wouldn’t call it a flyoff; it’s a comparison testing of the A-10 and the F-35. And given that the department was given that task … that is in [the] operational test and evaluation plan.”
Initial Operational Test and Evaluation, or IOTE, is set to begin for the F-35 in September 2018. But two new increments of preliminary testing were recently added to the calendar to evaluate specific capabilities, Winter said.
The first increment, which was completed in January and February 2018, took place at Eielson Air Force Base in Alaska and evaluated the ability of the aircraft to perform in extreme cold weather conditions, with a focus on the effectiveness of alert launches. The results of those tests have yet to be made public.
The second increment, set to begin in April 2018, will focus on close-air support capabilities, reconnaissances, and limited examination of weapons delivery, Winter said. The testing is expected to take place at Edwards Air Force Base in California and other ranges in the western United States.
Questions surrounding the F-35’s ability to perform in a close-air support role are what prompted initial interest in a comparison between the aging A-10 “Warthog” and the cutting-edge fighter in the first place.
The requirement that the two aircraft go up against each other was included as a provision in the National Defense Authorization Act for 2017 amid congressional concerns over plans to retire the A-10 and replace it with the F-35.
In an interview with Military.com in 2017, Air Force Brig. Gen. Scott Pleus, then-director of the F-35 program’s integration office, said he expected the A-10 to emerge as a better CAS platform in a no-threat environment.
But the dynamics would change, he said, as the threat level increased.
“As you now start to build the threat up, the A-10s won’t even enter the airspace before they get shot down — not even within 20 miles of the target.”
The US military is supporting research focused on genetically-engineering marine life for the purpose of tracking enemy submarines.
Research supported by the Naval Research Laboratory indicates that the genetic makeup of a relatively common sea organism could be modified to react in a detectable way to certain non-natural substances, such as metal or fuel, left behind by passing submarines, Defense One reports.
If the reaction involves the loss of an electron, “you can create an electrical signal when the bacteria encounters some molecule in their environment,” Sarah Glaven, an NRL researcher, said at a November 2018 event hosted by the John Hopkins University Applied Physics Lab, reportedly noting that the aim is to use this biotechnology to detect and track submarines.
“The reason we think we can accomplish this is because we have this vast database of info we’ve collected from growing these natural systems,” she further articulated. “So after experiments where we look at switching gene potential, gene expression, regulatory networks, we are finding these sensors.”
She said that hard evidence that this sort of biotechnology breakthrough is possible and capable of being used to serve the military is about a year away.
In 2018, the Defense Advanced Research Projects Agency (DARPA), the research and development arm of the Pentagon, revealed a desire to harness marine organisms for the monitoring of strategic waterways.

“The US Navy’s current approach to detecting and monitoring underwater vehicles is hardware-centric and resource intensive. As a result, the capability is mostly used at the tactical level to protect high-value assets like aircraft carriers, and less so at the broader strategic level,” Lori Adornato, manager for the Persistent Aquatic Living Sensors (PALS) program, said in a statement.
“If we can tap into the innate sensing capabilities of living organisms that are ubiquitous in the oceans, we can extend our ability to track adversary activity and do so discreetly, on a persistent basis, and with enough precision to characterize the size and type of adversary vehicles.”
As is, there is already a million tri-service effort among Army, Navy, and Air Force researchers to use synthetic biology to advance US defense capabilities. “Our team is looking at ways we can reprogram cells that already exist in the environment to create environmentally friendly platforms for generating molecules and materials beneficial for defense needs,” Dr. Claretta Sullivan, a research scientist at the Air Force Research Laboratory’s Materials and Manufacturing Directorate, explained in a statement.
There are apparently similar programs going on across the branches looking at everything from undewater sensing to living camouflage.
The US is once again in an age of great power competition, according to the 2018 National Defense Strategy. It faces new threats from adversarial powers like China and Russia beneath the waves. “In the undersea domain, the margins to victory are razor thin,” Adm. James G. Foggo III, the commander of US Naval Forces Europe-Africa, told Pentagon reporters in October 2018.

One of the most challenging parts of deployment for many soldiers is being away from friends and family. Soldiers and family members alike often lean on others who share a similar experience during long periods apart.
But one family in the 1st Cavalry Division’s 3rd Armored Brigade Combat Team is sharing an experience here to make deployment just a little bit easier.
Army Capt. Andrea Wolfe and her son, Army Spc. Kameron Wideman, both assigned to Brigade Support Medical Company, 215th Brigade Support Battalion, deployed to Kuwait recently from Fort Hood, Texas, for nine months in support of U.S. Army Central.
Wolfe, a native of Kingston, Jamaica, began her Army career as an enlisted lab technician 24 years ago.
“I had two sisters who were in the Army,” she said. “I followed them in. In a family of nine, we couldn’t afford college, so I had to do something to be able to get some kind of college education, and that was the way.”
As far back as she can remember, she said, she wanted to be a nurse. “It’s just something I wanted to get into to help people,” she added.
That aspiration propelled her through her career, taking advantage of educational opportunities in an effort to make her dream a reality. “I tried to get into the nursing program,” she said. “When I was a lab tech instructor in San Antonio, I put in my packet three times for the nursing program.”
After 17 years of enlisted service and multiple attempts, the frustrated sergeant first class decided to try something different.
“So I put in a packet to the [physician assistant] program, got picked up the first time, so I figured that was my calling, and I’ve been doing that since 2009,” she said.
Meanwhile, Wolfe was raising a family. Her son, Kameron Wideman, was born in 1996 at her first duty station in Fort Lewis, Washington. Brought up in a devoted military household, it was no surprise when he enlisted in the Army, Wolfe said.
“I was good in school, but I didn’t take it seriously enough, but the Army was always my fallback plan,” said Wideman, a behavioral health technician. “I initially wanted to join just so I could help people. That’s why I got into the medical field.”
Meanwhile, Wolfe and Wideman are tending to the physical and mental well-being of the soldiers deployed to Camp Buehring, Kuwait. Wolfe said that while her focus is on her job and taking care of the soldiers, the mom in her can’t help but feel some of the same concerns stateside parents feel about having a child deployed.
“As a mother, you still have that deep-down concern of ‘What if something happens to my baby? What am I going to do?'” she said. “But I can’t let him see that, because I need him to focus on his job and what I need him to do, and that’s to provide mental health, which is something that is very much needed in this day and age.”
Wideman said he enjoys having his mother right down the road. “I’m blessed,” he said. “I’m blessed to have her with me.”
Although Wideman has served only two years in the Army, he is no stranger to the deployment experience from a family member’s perspective. His mother, father, and stepfather all serve on active duty.
“All three of my parents have deployed at some point,” he said. “It was tough as a little kid saying goodbye to your parents. When you’re little, you tend to have a big imagination. You’re thinking, ‘Oh no! I’m probably never going to see my parents again,’ because you’re little, and you’re in your own head about it.”
But the experience of being the kid who was left behind didn’t prepare him to actually be deployed himself, he said.
“I still didn’t really know what deployment was,” he said. “It was like this random place that my parents were going to for like a year and then coming back. I didn’t really know how to picture where they were.”
Thankfully, he said, he had a source close to home to answer his questions.
“I had the normal questions like, ‘How are we going to be living?” and me being a millennial, ‘Is there going to be Internet?’ and things like that,” he said.
Wolfe and her husband, Army 1st Sgt. Andrew Wolfe, a company first sergeant at Carl R. Darnall Army Medical Center at Fort Hood, Texas, help mentor Wideman through his Army career with advice and guidance.
Drive, Motivation, Discipline
Echoes of the same drive, motivation, dedication and discipline that exemplify Wolfe’s career path are evident in Wideman’s.
“We cross paths every now and then,” she said. “I don’t see him all the time. I let Kameron be Kameron. We are passionate about the military. This is our Army. My husband is a first sergeant, and I used to be an E-7 before I switched over, so that leadership is instilled in both of us, and that comes out in the way we raise our kids — the leadership, the discipline, the morale, the ethics, everything. This is the way you’re supposed to live.”
Wolfe said she often finds herself giving the same advice to her soldiers that she gives to her son.
“Get all you can out of the military, because it’s going to get all it can out of you, and that was my insight coming up,” Wolfe said.
“I don’t know how many colleges I went to, because I needed classes. I went to school all the time, and I was just taking advantage of the opportunities that were out there. That’s what I tell all my soldiers coming up in the military. You have to take advantage of it. No one’s going to give it to you. You have to go and get it.”
Everyone gets that “2:30 feeling.” Military personnel happen to get it at all times of day. Maybe you’re on mids. Maybe you’re in transit from Afghanistan to Japan. Or maybe you’re being punished for doing something stupid. It happens. But we don’t always have access to Five Hour Energy shots, and sometimes coffee isn’t cutting it. The best thing to do is give in: have your battle cover you while you rack out for a few minutes.
Or maybe fifteen? A half-hour? A full hour? How long is the proper power nap? Thanks to NASA, we have the answer.
“We can put a man on the moon, but we can’t… what? We can? Oh, thanks, NASA.”
There’s no shame in needing a little afternoon siesta. Anyone who swears by the power nap will tell you that nodding off for a few minutes can revive them for hours. Just don’t let the First Sergeant catch you. But if you can get away with it on duty, you (and your coworkers) will be grateful to find you more productive and operating at a higher level. It’s a natural part of human circadian rhythm, you’re going to be intensely sleepy twice per day. You can’t stop it, none of us can.
So stop blaming the turkey already.
NASA’s research showed that naps really can fully restore cognitive function at the same rate as a full night’s sleep. The space agency found that pilots who slept in the cockpit for 26 minutes showed alertness improvements of up to 54 percent and job performance improvements by 34 percent, compared to pilots who didn’t nap. But 26 minutes might be a little long.
“Napping leads to improvements in mood, alertness and performance [such as] reaction time, attention, and memory,” according to Kimberly Cote, Ph.D, Professor of psychology and neuroscience at Brock University, who co-authored a similar study with researcher Catherine Milner. “Longer naps will allow you to enter deeper sleep, which will contribute to the grogginess — also called sleep inertia — experienced upon awakening and disrupt nighttime sleep.”
The worst part is when you wake up and you’re still in Afghanistan.
Cote and NASA suggest taking power naps between 10 and 20 minutes long. You’ll get the most benefit from a sleep cycle without any of the grogginess associated with longer sleeping periods. You don’t need to get through all five sleep stages, just the first two. Even just getting to stage 2 sleep for a few minutes will revive a napper enough to give him or her a new outlook on the day.
So get cozy and rack out for a few. It’s actually better for everyone.
Imagine putting your life into the paws of a Labrador retriever or German shepherd. Would you feel safe?
For many Marines this becomes their reality when deployed to a combat zone. German shepherds and Labrador retrievers are specially trained for drug detection, suspect apprehension and explosive detection.
“Before Don was assigned to me, I noticed that his detection was impeccable,” stated Devaney. “When I heard that Don was being assigned to me, I couldn’t have been happier.”
Don’s training started when he was just 6 months old at Lackland Air Force base in Bexar, Texas. He then finally made his way to Camp Pendleton at the age of 2 and was assigned to another Marine prior to being assigned to Devaney.

“You could see the adjusting from Don’s prior handler to me,” said Devaney. “There were adjustments that needed to be made on both of our parts. Knowing that we both had the same goal to protect the base and the people that reside on the base, we needed to create this bond between us.”
It is the handlers’ job to ensure that they are both ready at any time to deploy. Trust and understanding between the handler and the dog keeps the team and everyone around them safe.
“It was a lot of extra time on my part. Coming to the kennels on my off days or staying after work and just spending the time with him. Getting to know all of his quirks and understanding all of the pieces that make up his personality,” said Devaney. “Through this one on one time, Don learned my limitations too. Together we learned how to successfully achieve the mission.”

The first couple of months after a handler is assigned to a dog it is crucial to their training. A handler is expected to spend roughly fifty hours a week with their dog developing a relationship. Beginning as a pup, the dogs are trained to listen to their handlers. The dog needs to trust and know the individual before they begin to listen to the commands given to them. Without the strong connection between the two, there is a hesitation on completing the mission.
“Don, he is kind of a weirdo. He has a lot of quirks and it took me some time to learn all of them,” stated Devaney. “One of Don’s favorite things to do is chew on my boots when we’re spending time together. He is everything to me now and he is the drive that gets me out of bed in the morning.”
Having military working dogs on Camp Pendleton is a force multiplier. Military working dogs protect Pendleton during building searches, suspect apprehension, active shooters, threat identification and alarm activation calls.
“For the Marine Corps, I believe that dogs are invaluable. They are so applicable in different situations,” said Devaney. “For our forward deployed Marines, they are out there searching for IED’s, tracking and looking for high value targets. When you pair a good dog and a good handler together, they’re unstoppable.”

Doctors, nurses, and other embarked medical personnel aboard the hospital ship USNS Comfort (T-AH 20) conducted a mass casualty training exercise in preparation for visiting medical sites in Central and South America, Oct. 13, 2018.
The exercise tested Comfort’s crew in mass casualty triage, care, and first-aid practices. Participants included multi-service members, partner nation service members, and mission volunteers.
“A mass casualty event, by nature, is chaotic,” said Lt. Jessie Paull, a general surgery resident embarked on Comfort. “Being able to practice, it gets your nerves under control.”

Comfort is on an 11-week medical support mission to Central and South America as part of U.S. Southern Command’s Enduring Promise initiative. Working with health and government partners in Ecuador, Peru, Colombia, and Honduras, the embarked medical team will provide care on board and at land-based medical sites, helping to relieve pressure on national medical systems caused partly by an increase in cross-border migrants. The deployment reflects the United States’ enduring promise of friendship, partnership, and solidarity with the Americas.
“Star Wars: The Rise of Skywalker” is heading for the worst opening at the China box office of Disney’s new “Star Wars” movies.
The movie had earned $2.2 million in the region by 8 p.m. local time on Friday, according to Variety, and was trailing behind three Chinese movies. The Chinese ticket service Maoyan is projecting “The Rise of Skywalker” to earn just $18 million during its theatrical run in China.
The “Star Wars” franchise has struggled to build an audience in the country, where Hollywood is increasingly relying on its box office to boost its blockbusters. The Chinese theatrical market has been growing at a rapid pace and is even projected to dethrone the US as the world’s box-office leader within the next few years.
Each Disney-era “Star Wars” movie has made less in China than the previous one. Here’s how each of them performed there:
“The Force Awakens” — 4 million
“Rogue One” — million
“The Last Jedi” — million
“Solo” — million
Despite the lack of enthusiasm in China, all of those movies except “Solo” grossed over id=”listicle-2641661309″ billion worldwide. “The Force Awakens” earned over billion globally and 6 million domestically.
“The Rise of Skywalker” is expected to have a big opening domestically this weekend — despite negative reviews — but still less than the previous movies in the new trilogy. Boxoffice.com is projecting the movie to debut between 0 million and 0 million. “The Force Awakens” opened with 8 million domestically and “The Last Jedi” with 0 million.
“The Rise of Skywalker” so far has a 57% critic score on Rotten Tomatoes, making it the worst-reviewed “Star Wars” movie since “The Phantom Menace.”

One of the most successful and enduring feats of interplanetary exploration, NASA’s Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet.
The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity Feb. 12, 2019, to no avail. The solar-powered rover’s final communication was received June 10, 2019.
“It is because of trailblazing missions such as Opportunity that there will come a day when our brave astronauts walk on the surface of Mars,” said NASA Administrator Jim Bridenstine. “And when that day arrives, some portion of that first footprint will be owned by the men and women of Opportunity, and a little rover that defied the odds and did so much in the name of exploration.”
Designed to last just 90 Martian days and travel 1,100 yards (1,000 meters), Opportunity vastly surpassed all expectations in its endurance, scientific value and longevity. In addition to exceeding its life expectancy by 60 times, the rover traveled more than 28 miles (45 kilometers) by the time it reached its most appropriate final resting spot on Mars – Perseverance Valley.
“For more than a decade, Opportunity has been an icon in the field of planetary exploration, teaching us about Mars’ ancient past as a wet, potentially habitable planet, and revealing uncharted Martian landscapes,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “Whatever loss we feel now must be tempered with the knowledge that the legacy of Opportunity continues – both on the surface of Mars with the Curiosity rover and InSight lander – and in the clean rooms of JPL, where the upcoming Mars 2020 rover is taking shape.”
The final transmission, sent via the 70-meter Mars Station antenna at NASA’s Goldstone Deep Space Complex in California, ended a multifaceted, eight-month recovery strategy in an attempt to compel the rover to communicate.
“We have made every reasonable engineering effort to try to recover Opportunity and have determined that the likelihood of receiving a signal is far too low to continue recovery efforts,” said John Callas, manager of the Mars Exploration Rover (MER) project at JPL.
The dramatic image of NASA’s Mars Exploration Rover Opportunity’s shadow was taken on sol 180 (July 26, 2004) by the rover’s front hazard-avoidance camera as the rover moved farther into Endurance Crater in the Meridiani Planum region of Mars.
Opportunity landed in the Meridiani Planum region of Mars on Jan. 24, 2004, seven months after its launch from Cape Canaveral Air Force Station in Florida. Its twin rover, Spirit, landed 20 days earlier in the 103-mile-wide (166-kilometer-wide) Gusev Crater on the other side of Mars. Spirit logged almost 5 miles (8 kilometers) before its mission wrapped up in May 2011.
From the day Opportunity landed, a team of mission engineers, rover drivers and scientists on Earth collaborated to overcome challenges and get the rover from one geologic site on Mars to the next. They plotted workable avenues over rugged terrain so that the 384-pound (174-kilogram) Martian explorer could maneuver around and, at times, over rocks and boulders, climb gravel-strewn slopes as steep as 32-degrees (an off-Earth record), probe crater floors, summit hills and traverse possible dry riverbeds. Its final venture brought it to the western limb of Perseverance Valley.
“I cannot think of a more appropriate place for Opportunity to endure on the surface of Mars than one called Perseverance Valley,” said Michael Watkins, director of JPL. “The records, discoveries and sheer tenacity of this intrepid little rover is testament to the ingenuity, dedication, and perseverance of the people who built and guided her.”
More Opportunity achievements
Set a one-day Mars driving record March 20, 2005, when it traveled 721 feet (220 meters).
Returned more than 217,000 images, including 15 360-degree color panoramas.
Exposed the surfaces of 52 rocks to reveal fresh mineral surfaces for analysis and cleared 72 additional targets with a brush to prepare them for inspection with spectrometers and a microscopic imager.
Discovered strong indications at Endeavour Crater of the action of ancient water similar to the drinkable water of a pond or lake on Earth.
All of the off-roading and on-location scientific analyses were in service of the Mars Exploration Rovers’ primary objective: To seek out historical evidence of the Red Planet’s climate and water at sites where conditions may once have been favorable for life. Because liquid water is required for life, as we know it, Opportunity’s discoveries implied that conditions at Meridiani Planum may have been habitable for some period of time in Martian history.
“From the get-go, Opportunity delivered on our search for evidence regarding water,” said Steve Squyres, principal investigator of the rovers’ science payload at Cornell University. “And when you combine the discoveries of Opportunity and Spirit, they showed us that ancient Mars was a very different place from Mars today, which is a cold, dry, desolate world. But if you look to its ancient past, you find compelling evidence for liquid water below the surface and liquid water at the surface.”
All those accomplishments were not without the occasional extraterrestrial impediment. In 2005 alone, Opportunity lost steering to one of its front wheels, a stuck heater threatened to severely limit the rover’s available power, and a Martian sand ripple almost trapped it for good. Two years later, a two-month dust storm imperiled the rover before relenting. In 2015, Opportunity lost use of its 256-megabyte flash memory and, in 2017, it lost steering to its other front wheel.
Each time the rover faced an obstacle, Opportunity’s team on Earth found and implemented a solution that enabled the rover to bounce back. However, the massive dust storm that took shape in the summer of 2018 proved too much for history’s most senior Mars explorer.
“When I think of Opportunity, I will recall that place on Mars where our intrepid rover far exceeded everyone’s expectations,” Callas said. “But what I suppose I’ll cherish most is the impact Opportunity had on us here on Earth. It’s the accomplished exploration and phenomenal discoveries. It’s the generation of young scientists and engineers who became space explorers with this mission. It’s the public that followed along with our every step. And it’s the technical legacy of the Mars Exploration Rovers, which is carried aboard Curiosity and the upcoming Mars 2020 mission. Farewell, Opportunity, and well done.”
Mars exploration continues unabated. NASA’s InSight lander, which touched down on Nov. 26, is just beginning its scientific investigations. The Curiosity rover has been exploring Gale Crater for more than six years. And, NASA’s Mars 2020 rover and the European Space Agency’s ExoMars rover both will launch in July 2020, becoming the first rover missions designed to seek signs of past microbial life on the Red Planet.

The Ghost Gunner 2 ecosystem receives an upgrade with April 20, 2019’s release of the company’s updated 1911 jig. The new jig replaces the original, 45 ACP caliber-only jig with an update that holds 9mm, 10mm, 40S&W, and 38 Super caliber 1911 80% frames.
The Ghost Gunner 2 is a desktop CNC mill that finishes user-supplied 80% lowers using the included DDCut software. Connect it to your Mac or PC and using the corresponding accessory jig and tooling, the microwave oven-sized machine finishes 80% AR-15, AR-10, and 1911 lowers and frames made of aluminum or polymer. The GG2 is a full-featured desktop CNC mill that accepts open-source milling code and cuts anything else, as long as it’s aluminum or softer. You just need to find (or write your own) g-code and supply a jig to hold the workpiece in the machine.
The new Delrin 1911 jig replaces the original aluminum jig and includes a few changes that allow the installation of 1911 frames in multiple calibers. The change from metal to Delrin eliminates the chance of a failed probing operation that could occur when the anodizing on the older aluminum jig was worn or damaged. Improvements to the 1911 milling code include soft probing and an extended probing for the commander size frame.
The new 1911 jig is available for pre-order as a kit including tooling and other accessories for 5. It’s also offered alone for those that already have the tooling and costs 0. This machine is commonly confused with the hot topic of 3D printing guns, but this is a desktop CNC milling machine, not a 3D printer; it cuts metal and polymer.

Much has been written about the threat of Islamic State militants’ use of unmanned aerial vehicles, UAVs, commonly known as drones, over the embattled city of Mosul.
IS was quick to weaponize UAVs with small improvised explosive devices.
On Jan. 24, they released a video showing up to 19 different aerial attacks by commercially purchased UAVs — the kind of drone you can buy in any shopping center. Iraqi forces have followed suit by attaching modified 40mm grenades with shuttlecock stabilizers onto their larger UAVs to drop on IS positions.
A crude inaccurate way of killing terrorists, its effectiveness is questionable. Weaponized IS UAVs have mainly been used to target Iraqi military commanders and troops congregating in the open near the front line.
It’s a low-end, low-altitude attack that can be thwarted by keeping in hard cover.
But both sides use the UAV’s more effectively as a means of providing Intelligence Surveillance and Reconnaissance, known as ISR.
Islamic State UAVs in the air, once identified, are the warning that something is about to happen — either mortar fire, which is typically one hastily fired inaccurate round — before coalition air superiority can locate and target the firing point.
Or, more devastatingly, the launching of a Suicide Vehicle Borne Improvised Explosive Device, an SVBIED.
Since the Battle for Mosul officially started on Oct. 16, 2016, hundreds of SVBIEDs have been launched.
Recently, Sky News’ Special Correspondent Alex Crawford and cameraman Garwen McLuckie faced a number of SVBIEDs during their reporting from West Mosul’s front line.
Each time a small UAV was hovering high above. One occasion two were spotted.
Chief Correspondent Stuart Ramsay, cameraman Nathan Hale and Producer Haider Kata were also targeted by a SVBIED. On this occasion the UAV filmed the SVBIED (an armored Fronting Loader) to its intended target, a tank.
Later, the video was posted on Islamic State websites.
Due to the built-up urban area and the ever-changing nature of the battle, IS drivers of the SVBIEDs are believed to be hiding in garages with their heavily armoured explosive-laden vehicles. Modified with armor at the front and cameras on the wing mirrors, they provide militants with a 360-degree view of the battlefield and are notoriously difficult to stop.
They wait as the Iraqi forces move slowly forward, seizing ground and minimizing the driving distance to strike.
If they launch too early, the SVBIED will be exposed to air strikes or anti-tank fire, the only two real ways of neutralizing the vehicle.
But hidden IS drivers may not know the exact location of the moving Iraqi forces or be familiar with the streets and or access routes to their targets.
This is where the UAV is the key component to the attack.
The operators of the UAV act as navigators for the suicide driver; guiding him by radio or cell phone through battle-worn streets, they can help deliver the driver to his intended target with greater efficiency and accuracy.
This is a deadly combination.
The coalition has attempted to blanket all of Mosul in a red no-fly zone for commercially purchased UAVs, but this has been thwarted by either smart software adjustments to the unit or by placing aluminum material over the GPS.
Other methods have included the Battelle Drone Defender gun (hand portable beam type weapon) and the Spynel infrared camera, which is used to locate incoming UAVs. Both have been very limited, as UAV use is usually confined within a few hundred meters at the very front of the fight where these systems are not always deployed.
If an IS UAV is sighted, the immediate response by Iraqi forces is to engage it with small and heavy weapons, a difficult shot when aiming at a high flying fast moving object of no more than a meter wide.
After the firing has stopped, all attention shifts to street level as experienced operators know the next thing coming will be more deadly.
Many harmless recreational drones have now become deadly tools of war.
The various developers of these off-the-shelf UAVs probably never envisaged that their products would be used in a lethal cat and mouse hunt through Mosul’s war-torn streets.
There are no stupid questions…except for these ones!
When civilians have burning questions about the military, they turn to the only trusted source out there: the internet. Luckily for us, this means we get to relive our glory days and have a little bit of amusement. What’s the best thing to do when civvies ask something like, “Should I wear my cowboy hat at basic training for the Air Force?”
Gather a group of your military buddies, have some drinks, and turn the camera on:
Should you wear your cowboy hat to basic training? | Dumb Military Questions 101
For the record, it was a unanimous ‘yes’ to wearing your cowboy hat to basic training. It was the first time there was peace, belonging, and unbridled respect among the five branches.
Other questions were less universal or specifically catered to the specops vets in the group:
“How do special forces soldiers *really* open velcro quietly?”
Luckily, Green Beret Terry Schappert was on hand with a few suggestions. “Just throw a flashbang grenade. That gives you enough time and noise to open the velcro.” Problem solved. Thanks, Schappert.
“Are tall and strong soldiers more effective than short, thin soldiers?”
Now this one opened up some varied points. On the one hand, tall, strong soldiers can’t fit inside tanks, as U.S. Air Force vet Mark Harper sagely observed. But on the other hand, just look at U.S. Navy SEAL Remi Adeleke. Do we even need tanks? Really? If given the choice between the two…
