The Marine Corps' new exoskeleton will let grunts move heavy crap like Ripley in 'Aliens'

QUANTICO, Va. -- Marines who spend much of their day lifting hefty ammunition or moving pallets full of gear could soon get a helping hand.

The Marine Corps is close to signing a deal to test an exoskeleton prototype that can help a single person move as much as several leathernecks combined.

The Guardian XO robot, which was on display at the Modern Day Marine 2019 exposition in Quantico, Virginia, is a full-body autonomous exoskeleton suit being tested by the Air Force and U.S. Special Operations Command. Officials with Sarcos Robotics, which makes the system, say it can also take loads of stress off Marines' bodies.

"It keeps the human instinct and intelligent judgment and combines it with a robotic precision, strength and endurance to get to a more efficient, effective, more productive -- and frankly safer -- work environment," said Jim Miller, Sarcos Robotics' vice president of defense solutions.

The intuitive, autonomous suit can be used by operators ranging from 5 foot, 4 inches, to someone who's just over 6-and-a-half-feet tall. It stays powered for up to eight hours on a single charge and can repeatedly lift 200-pound objects without fatigue or strain.

For Marines, Miller said it's perfect for those who work in logistics and sustainment. Think those who move a lot of heavy boxes or repeatedly lift heavy artillery.

"Instead of a team of four Marines, maybe you only need a Marine with this capability to offload pallets or move or load munitions," he said. "I think we really need to get out there and become involved directly with a ... variety of Marine users to [see where we can take it]."

The system, without its power pack, weighs about 200 pounds. But the operator doesn't feel much of that weight, Miller said. The Guardian XO uses what the company calls a "get-out-of-the-way control system" that senses an operator's instincts and reflexes.

"The sensors can feel if you want to move up and says, 'Hey, he wants to move up because the pressure is increasing. Let's get out of his way, let's move,'" he said. "And if you stop, the sensors will feel it."

Sarcos Robotics has produced a couple of prototypes of the exoskeleton. In December, it will produce the first one that looks like the black and yellow design that was on display at Modern Day Marine. The exoskeleton gave the mannequin in MARPAT camo a look similar to the character Bumblebee from the Transformers film franchise.

Miller said the Air Force and Marine Corps will likely each get one or two of the suits to test out next year, depending on how many each service wants to purchase.

Once troops begin testing the prototype, he said they'll try to build capabilities based around their needs. If Marines or other service members want to use it downrange, they'll also test the suit's ability to withstand harsher environments, he said.

Aside from those in defense, Miller said the Guardian XO could be used in the automotive manufacturing, construction and aviation fields.

"Basically, anywhere you're going to be loading and moving things around," he said.

In time, it could go a long way in saving the military money, he added. If Marines are asked to move 40- or 50-pound boxes every day, that's going to take a toll.

"You might get one to three years, but even then I'm going to be broken, and the military and our government just incurred a bill to take care of me for the rest of my life," Miller said.

The Guardian XO takes away that burden, he said.

The Citizens of Ebey's Reserve (COER) is asking a federal judge to require the Navy to roll back the number of EA-18G Growler practice flights at Outlying Field Coupeville to pre-2019 levels until a lawsuit over the number of Growler flights is settled.

COER and private citizen Paula Spina filed a motion for a preliminary injunction Thursday.

According to the motion, since March 2019 the Navy has increased the number of Growlers at Naval Air Station Whidbey Island and shifted most of its Growler operations to Outlying Field Coupeville, which is near the Reserve and the town of Coupeville.

"The result is a nearly fourfold increase in Growler flights in that area. Now the overflights subject residents in and near Coupeville to extreme noise for several hours of the day, day and night, many days of the week," said the court document.

LOS ANGELES — For decades, Japanese American activists have marked Feb. 19 as a day to reflect on one of the darkest chapters in this nation's history.

On that date in 1942, during World War II, President Franklin Delano Roosevelt authorized the forced removal of over 120,000 Americans of Japanese descent from their homes and businesses.

Kirtland Air Force Base isn't much different from the world beyond its gates when it comes to dealing with mental illnesses, a base clinical psychologist says.

Maj. Benjamin Carter told the Journal the most frequent diagnosis on the base is an anxiety disorder.

"It's not a surprise, but I anticipate about anytime in the population in America, about 20% of the population has some form of diagnosable anxiety disorder, and it's no different in the military," he said.

Leading the way among the anxiety disorders, he said, were post-traumatic stress disorder "or something like panic disorder or generalized anxiety disorder."
