ABERDEEN PROVING GROUND, Md. — An unpowered exosuit designed to reduce the physical demands placed on Soldiers is one step closer to adoption after prototypes earned passing grades from more than 100 Soldiers at three Army posts.

According to the U.S. Army Public Health Center, low back injuries result in more than one million lost or limited duty days for Soldiers each year.

The Army’s Pathfinder program — led by a collaborative team of Soldiers from the 101st Airborne Division at Fort Campbell, Kentucky, and engineers at Vanderbilt University — brought about the design and testing of unique, exoskeleton prototypes to augment lifting capabilities and reduce back strain for sustainment and logistics operations.

The research and development of the soft, lightweight, unpowered exoskeleton, called the Soldier Assistive Bionic Exosuit for Resupply, or SABER, has moved from the Pathfinder team to the U.S. Army Combat Capabilities Development Command Soldier Center, or DEVCOM SC. The DEVCOM SC team is preparing the suit for manufacturing and robust field trial use by the Army.

The Pathfinder program is a congressional initiative to advance the Army Futures Command’s modernization goals and support the innovation of Soldier-inspired, research-based technologies like SABER. DEVCOM officials said they leverage the program to connect Soldiers with its global science and technology network, which ranges from fundamental research to advanced technology upgrades to already fielded equipment.

“By engaging Soldiers earlier in the research and development process, we are able to make them aware of emerging research and technologies that academia can provide to help meet their needs,” said Dr. Arwen DeCostanza, Pathfinder program manager. “Collaborative projects like this one, yield discoveries and future outcomes by capitalizing on the creativity of Soldiers, faculty, students, industry partners and the Army science and technology community.”

Working with Soldiers in the 101st Airborne Division, researchers at Vanderbilt designed SABER as a wearable device that is soft, lightweight and form fitting. This unmotorized device can be selectively engaged by the Soldier to assist lifting capabilities.

The exosuit design addresses needs identified by the Soldiers, such as aiding strenuous lifting tasks like ammunition resupply and reducing injury and fatigue, critical to readiness over sustained periods.

“We spent the first few months focused on interviewing, observing and spending time with Soldiers,” said Dr. Karl Zelik, associate professor of mechanical engineering, Vanderbilt University. “We didn’t try to create Iron Man — a complex, full-body, rigid, unrealistic suit. Instead, we started by deeply understanding Soldier needs to develop a lightweight, low-profile, non-powered wearable tool that helps provide much-needed assistance without slowing Soldiers down or interfering with other operational tasks.”

To develop the idea for this project, Vanderbilt engineers engaged Soldiers in frequent interviews, design sprints and field tests to identify critical problems hindering their daily duties in the field. Physical overexertion stood out as a problem in need of a rapid solution.

To address strength and endurance limitations associated with material handling and field artillery, Vanderbilt researchers, engineers, technology translation experts and other military partners — working alongside Soldiers — took an exoskeleton technology Vanderbilt had previously designed for commercial use and spent a year of iterative development and testing to transform it into the SABER system.

In designing the system, the team focused on extended use of the suit during critical tasks to address Soldier load and movement issues.

More than 100 Soldiers participated in testing of the exosuit at three different bases, reporting less back strain and greater endurance while wearing SABER prototypes.

“Over the course of the day, lifting 60-pound rounds you get worn out, especially after hours. It takes a toll on your body,” said Pfc. Dale Paulson, 101st Airborne Division. “Wearing the suit really helped a lot, especially with getting the rounds out of the back of the truck. It felt like it gave me an extra boost. I didn’t have to work as hard. I feel like it helped me move quicker.”

Biomechanical evaluations revealed that the three-pound suit reduced stress on Soldiers’ backs by more than 100 pounds while lifting. Additionally, most Soldiers increased their endurance by over 60 percent while wearing SABER.

An overwhelming 90 percent of Soldiers surveyed after operational field testing in May 2022 believed the exosuit increased their ability to perform job tasks, and all of them reported that they would be likely to wear it for their job if it were developed into a product and made available to them.

DEVCOM Army Research Laboratory, in cooperation with DEVCOM SC, is providing funding to HeroWear, a Nashville-based industrial exosuit manufacturer and to Vanderbilt University to iteratively design and fabricate dozens of pre-production units in late 2022, with the goal to ramp up to hundreds of units in 2023.

DEVCOM SC will also conduct field demonstrations for critical stakeholders, getting the technology in the hands of the 101st Soldiers and other units, while simultaneously working a broader transition path.

“We were extremely proud to be recognized by our fellow DEVCOM and AFC leads as partners of choice in understanding the technology, and how to introduce this game-changing capability to Soldiers,” said Dave Audet, chief, systems division, DEVCOM SC. “Our on-going DEVCOM Soldier Center exoskeleton program and collaboration with Vanderbilt made it possible to accelerate technology modification and a successful transition from [the Army Research Laboratory] to Soldier Center.”

The DEVCOM Army Research Laboratory manages the Pathfinder program in close partnership with the DEVCOM Armaments Center. Civil-Military Innovation Institute executes the Pathfinder program on site at each military location and facilitates the interactions between military and universities.

Universities in North Carolina, Tennessee, West Virginia and Montana are working with the 82nd and 101st Airborne Divisions — both under XVIII Airborne Corps — several Special Operations Groups and West Virginia and Montana National Guard units, to identify and rapidly solve Soldier challenges and accelerate the transition of those solutions into the Army.

FORT HOOD, Texas – Robotic Combat Vehicles, or RCVs, will become the future for combat operations.

This is another reason why troopers with the 1st Battalion, 7th Cavalry Regiment “Garryowen,”, 1st Armored Brigade Combat Team, 1st Cavalry Division, are working with the Next Generation Combat Vehicle Cross Functional Team members to test different versions of the RCV platforms here until late summer 2022.

The testing started in late July with Soldiers training on the vehicles, followed by tactical scenarios and situational training exercises. Army engineers and technicians collected the Soldiers’ feedback, and will use that to further develop the robotic vehicle’s capabilities with the end-user in mind.

“Soldier feedback is the foundation for every single requirement we’re writing,” said Maj. Cory Wallace, RCV lead for the Next Generation Combat Vehicles Cross-Functional Team, during a training session, July 25. “If you have people (engineers) who are not connected with the Soldiers, every step of the process, we build stuff that is not useful, doesn’t work or seems way too expensive and it never leaves the motor pool.”

Garryowen troopers will have a chance to employ a tethered Unmanned Aerial System, a counter-UAS jammer, modular smoke obscuration module, a Commonly Remote Operated Weapon System (equipped with both crew-served weapons, up to 50-caliber, and a Javelin), as well as an autonomous drive function.

The RCV platforms have non-standard battery-powered systems. Soldiers are testing the limits of the vehicles in the Fort Hood training areas terrain, driving them on various terrain conditions commonly encountered on the battlefield. The Soldiers are also testing the vehicles’ ability to identify and avoid obstacles and their capacity to fire weapons while on the move.

“If you think about it, you know, in any … combat formation, 90 percent of it is a movement moving on unimproved surfaces from point A to point B. We can then off-load that onto a robot and have that robot do that, so the crews can perform more important tasks.” Wallace said.

Soldiers in the field have further validated the combat benefits of adding robots to a manned-unmanned teamed formation. On-site technicians have collected technical data, and the Soldiers have identified new capabilities desired for the operational experiment with the RCVs.

The Soldiers believe that the robots will be beneficial in several ways. First, they will provide increased situational awareness, more efficient use of resources, and greater flexibility in planning and execution. In addition, Wallace added, the Soldiers believe that the robots will reduce the risk to Soldiers’ lives by providing a safe way to gather information and conduct operations in dangerous environments. The on-site technicians will continue to collect data, and the Soldiers will continue to validate the benefits of adding robots to the formation.

“We are essentially planning and writing for the future. What we want to do is make sure we’re well prepared, and we have trained individuals so we can win the nation wars,” said Staff Sgt. Miguel Albertson, 1-7 Cav.

The Army is preparing to make future decisions on the potential acquisition and use of unmanned systems in combat by conducting additional Soldier training and evaluation sessions with RCV platforms over the next 36 months.

Soldiers will have the opportunity to provide input on how they believe unmanned systems could be employed in combat operations, as well as identify any challenges or limitations that should be considered. This feedback will inform future decision-making on the Army’s acquisition of the systems.

REDSTONE ARSENAL, Ala. — Imagine the possibilities of a self-driving vehicle on the battlefield.

Engineers at the U.S. Army Combat Capabilities Development Command Aviation & Missile Center, or AvMC, don’t have to imagine it, they are building it. The Autonomous Multi-Domain Launcher takes a High Mobility Artillery Rocket System — or HIMARS — and modifies it with hardware and software to be controlled remotely and driven autonomously.

“[The Autonomous Multi-Domain Launcher] represents a significant and exciting modernization improvement for the Army,” said Christi Dolbeer, director of DEVCOM Aviation & Missile Center’s Technology Development Directorate. “Adding autonomy to drive mobile launchers and increasing the firing power of those launchers represents a powerful combination. I am very proud of the DEVCOM AvMC and DEVCOM Ground Vehicle Systems Center teams working together to give Soldiers even greater capabilities.”

While it resembles the self-driving cars in the news, the Autonomous Multi-Domain Launcher — or AML — will have capabilities that those vehicles will never possess — but also challenges. Regular autonomous autos operate on established roadways, they aren’t navigating a sometimes treacherous terrain. They also aren’t being fired upon by enemy combatants. Then there is the matter of size.

“We are talking about putting a 36,000-pound vehicle in an area where there will be humans running around,” said Lucas Hunter, AML project manager for AvMC. “Tesla and other companies are working on vehicles that can sense cars in front of them and behind them; they have these nice stripes on the road that tell it, ‘I am getting out of my lane.’ Well, we are driving through open country, we don’t have stripes — we have holes, we have cliffs.”

AML in its current incarnation will look notably different than the final system as the existing cab will eventually be eliminated from the vehicle. Later iterations will also boast a new launcher and increased firing power.

AML was conceptualized as a tool to increase mass fires and “thicken the force,” but what exactly does that translate to in theater?

“AML applies a wingman concept to the Soldiers we already have on the battlefield,” Hunter said. “That spreads out capabilities. So more targets have to be addressed by the enemy. At the same time, it increases the number of rounds that our Soldiers have available which keeps them in the fight longer. With HIMARS, once they fire their six rounds, they have to reload. If you add 12 more, now they are able to support frontline troops three times as long.”

How this new capability will be utilized is currently being explored by the Fires Center of Excellence and the Strategic and Operational Rockets and Missiles Office. Concept testing was conducted in 2021 at Fort Sill, Oklahoma, to demonstrate how the wingman concept might look, emulating a mission with the Precision Strike Missile — the missile being part of the Army’s Long-Range Precision Fire cross-functional initiative and also in the AvMC portfolio.

For Hunter, AML marks not just a landmark paradigm shift for Army battlefield technology, but for the world of robotics itself. With the strides already made in breaking the manual chain and developing the robotic applique kit, it is easy to forget that AML has only been in existence since February 2020.

“There are all kinds of situational awareness challenges that the robotics industry is just now starting to look at,” Hunter said. “AML, which will be called HIMARS Increment 2, has to be able to travel wherever it is told to travel. It has to be able to tell, ‘Hey, there is a cliff right here.’ It has to be able to recognize whatever terrain it is on.

“This is a career field in robotics — how to enhance that situation awareness and do so in passive manners. We need sensors that collect situational awareness data without emitting detectable energy like light or sound. Because you don’t want this to light up like a Christmas tree when the enemy is looking.”

FORT BENNING, Ga. — The Department of Defense Close Combat Lethality Task Force hosted the Artificial Intelligence for Small-Unit Maneuver working group July 27 – 28 at Fort Benning.

The purpose of the working group was to establish a joint artificial intelligence community of interest to identify capability gaps, review existing AI initiatives and synchronize AI focus areas to improve lethality across DOD, and specifically, U.S. Army, U.S. Marine Corps and special operations close combat small-unit formations.

Participants included academic experts, representatives from the Office of the Under Secretary of Defense for Research and Engineering, Chief Digital and Artificial Intelligence Office and operational end-users from the U.S. Army, U.S. Marine Corps and U.S. Special Operations Command communities, each possessing a unique skill set on how to leverage AI for their specific missions.

“We are transforming the joint force by integrating next-generation technologies and war-fighting concepts,” said U.S. Army Col. Shannon Nielsen, director of the Close Combat Lethality Task Force. “[This] enhances our ability to compete globally, deter adversaries, and win on all-domain battlefields at the small-unit level.”

During the working group, participants discussed current and future AI initiatives and opportunities to synchronize Artificial Intelligence for Small-Unit Maneuver efforts to gain technological and resourcing efficiencies.

The Artificial Intelligence for Small-Unit Maneuver working group will continue to meet monthly with members of the joint AI community of interest to identify, prioritize, and advocate AI programs and DOD investment strategies to improve close-combat lethality.

GRAFENWOEHR, Germany — Combined Resolve 17 put an Army brigade and multinational units to the test on more than just their combat readiness and interoperability — the exercise brought future capabilities into the current fight.

Combined Resolve is a U.S. Army exercise consisting of 5,600 service members, Allies and partners from more than 10 countries, and is designed to assess units’ abilities to conduct combat operations effectively in a multi-domain battlespace. Combined Resolve 17 is scheduled to take place from May 20 to June 19, 2022.

The 1st Battalion, 4th Infantry Regiment — serving as the opposing force in Combined Resolve — pitted robotic combat vehicles, or RCVs, against the 1st Armored Brigade Combat Team, 3rd Infantry Division and their partner nations in simulated combat.

The RCVs are part of Project Origin, an initiative in development as part of the Army’s modernization efforts from the Ground Vehicle Systems Center, or GVSC, under the Army Combat Capabilities Development Command. The program tests and experiments with autonomous ground vehicles to support Army maneuvers and provide a variety of load packages, depending on the situation.

This training provided Project Origin engineers with real-time feedback on the capability, utility, and combat effectiveness of the latest generation of RCVs. The vehicles are remote or autonomously controlled and designed to assist with a wide range of operations including long-range reconnaissance, concealment, electronic warfare, and autonomous resupply operations.

“Anytime we can get technology in [Soldiers’] hands and find out, right away, what they like, what they don’t like, helps us to not expend resources in the wrong areas,” said Todd Willert, an engineer with GVSC. “Being out here with the [Soldiers] is the most productive thing for the Army’s Robotic Combat Vehicle Program.”

Soldiers with the 1st Battalion, 4th Infantry Regiment have been working with Project Origin since the beginning of Combined Resolve 17, however the current iteration of RCVs they are training with have already been through two weeks of hands-on experimentation with the 1st Special Forces Group at Dugway Proving Ground, Utah.

“This is something I didn’t think we would be seeing in the [Infantry] as soon as we are,” said Sgt. Andrew Carmichael, Sniper section leader with 1st Battalion, 4th Infantry Regiment. “It’s definitely here to stay, so the quicker we can expose our allies and our own forces to this technology and how to implement and defend against it, is crucial in the next fight.”

Soldier feedback within multinational exercises inform Army modernization on requirements operating in the coalition environment, promoting interoperability and communicates strength of a combined U.S., Allied and partner force to shape the security environment. At the conclusion of Combined Resolve the RCVs will be taken to Grafenwoehr Training Area in order further test their capabilities and conduct live fire training.
