(Washington, D.C.) The Army is preparing to fire Javelin Anti-Tank missiles from 7-ton robots able to surveil forward, high-threat areas, find and track enemy targets such as tanks and heavy armored vehicles and fire weapons when directed by a human.
In a recent Army demonstration at Fort Hood, Texas, soldiers tested the technology to eventually fire Javelins and .50-cal machine guns from robotic vehicle prototypes during a series of war preparation and weapons development exercises.
“We just finished our second large scale operational soldier evaluation done at Fort Hood, Texas, we had 12 robotic platforms with six control vehicles. It's a culmination of about four years of activity. This really, really is a huge learning opportunity for the Army to understand how combat robotics can inform future decisions on how we buy material and how we fight,” Kevin Mills, Deputy Executive Director, Ground Vehicle Intelligent Systems, Army Ground Vehicle Systems Center, told Warrior in an interview.
As part of the evaluation, Army weapons developers placed armed robots in the hands of soldiers to assess weapons, refine tactics and help fast-track a new class of Robotic Combat Vehicles to war. The service is moving forward with three variants, a RCV-Light, RCV-Medium and RCV-Heavy, and each robotic vehicle variant is being developed for a complex, interwoven set of unmanned missions. These include manned-unmanned teaming efforts wherein forward ground drones or robotic vehicles perform reconnaissance and scout missions, deliver supplies and ammo or actually track and destroy targets themselves when directed by a human.
“The RCV-Light is about a seven ton vehicle and carries a 50 .cal machine gun and a Javelin and several other weapon systems. It is built for modular payloads. The RCV-Medium fires a 30mm cannon from a turret. The lights and mediums were purpose built prototypes for the soldier operational experiment,” Mills said.

The Robotic Combat Vehicle - Heavy is earlier on in the developmental program but was used in the experiment with an M113 personnel carrier as a surrogate for a future heavy robot armed with a 120mm cannon. Mills explained that robotic vehicles armed with larger caliber systems will emerge more fully in coming years.
“One of the unique features of robotic platforms is that, once you take the human out, they're purposely built to be robotic platforms, so they can be much smaller and still carry significant payloads and have significant middle mobility characteristics. So the RCV lights, for example, are very hard to detect, so that right there gives you the operational advantage of being able to push them forward,” Mills said.
The Army’s development of these robots involves testing for future war by placing them in the hands of soldiers in specific tactical situations replicating combat operations against an opposing force.
During a recent Operational Soldier Evaluation at Fort Hood, Texas, Army units assessed the performance of new Robotic Combat Vehicle prototypes intended to extend the battlefield, greatly improve survivability and introduce a new range of tactical possibilities for ground forces preparing for future war.
“As you move towards an autonomous system or an unmanned system, a lot of the capability is software defined. It's no longer just hardware defined, but it creates a new set of challenges, as you have to manage a very complicated software system,” Mills said.

The Army’s Robotic Combat Vehicles, Light, Medium and Heavy, are now emerging as prototype weapons platforms being further developed for operational use. A key part of the Army’s development of new technologies involves testing them with soldiers in combat circumstances to see how they best operate.
“You're going to put a robotic combat vehicle in a formation, and we think we know how you're going to use it. But we're not right. Ultimately, the soldiers are going to help shape how it's used. That's really what AFC (Army Futures Command) is pushing for, to get technology in the dirt and allow soldiers to write those requirements, not come up with some exquisite end state threshold objective, and then 15 years from now we're going to achieve it. How do we iterate the requirements process as quickly as we can iterate software,” Mills told Warrior in an interview. “By giving us, you know, honest feedback, they (soldiers) definitely didn't hold back when things didn't work, or what they wanted to see improve. I think that's really the whole point of doing this is getting that feedback that allows me to go back to my engineers and say, okay, these are the things we have to fix.”
The developmental process, Mills explained, is intended to be incremental and progressive, involving ongoing collaboration between engineers and soldiers analyzing how new systems can best be leveraged in combat. There is a complex and extremely critical synergy between the emergence of new technologies and evolving concepts of Combined Arms Maneuver, and exercises such as the one at Fort Hood are designed to explore that intersection.
“It's really a chicken and egg thing because you're giving soldiers a new capability. And the worst thing you could probably do is say, hey, fight the exact same way with this new technology. What AFC (Army Futures Command) is really pushing for us to get technology in soldiers hands and let them innovate on the tactics and operations,” Mills said.

Army Can Now Drive 10-Truck Robotic Convoy
If a critical, high-value Army convoy were traveling through high-threat areas with soldiers, weapons, supplies and ammunition, it would rely upon extremely effective security when it comes to detecting enemy ambushes, finding IEDs or conducting forward reconnaissance to map the optimal way forward.
One way to improve security is to enable soldiers themselves to focus more fully on threat dynamics without having to expend energy and concentration driving. Increasingly, military vehicles can drive autonomously with minimal human supervision. Years ago, the Army successfully demonstrated an advanced, autonomy-enabled capability called “leader-follower” algorithms. Essentially, an unmanned or driverless truck can be programmed to precisely follow the maneuvers and route of the manned vehicle in front of it. Advanced algorithms enabling autonomy could guide, direct and simply drive accurately and precisely behind the vehicle in front. This technology pioneered more than 15 years ago, and has in recent years been breaking through in a paradigm-changing way.
“Where we are now, a manned leader vehicle can have up to 10 robotic, completely unmanned vehicles behind it, and those are operating with soldiers today on a prototype experimentation level. The goal, though, is to really remove those two manned vehicles and replace them with an autonomous capability that now allows those same convoys in ever increasing complexities of mission space to go from on-road to off-road to be able to execute those convoy missions without humans doing the driving functions. This can allow soldiers to do things like pull security for the convoy. That's something only a soldier can do,” Kevin Mills, Deputy Executive Director, Ground Vehicle Intelligent Systems, Army Ground Vehicle Systems Center, told Warrior in an interview.

Tactically speaking, the ability for an autonomous, unmanned front vehicle leading a convoy to perform reconnaissance missions certainly provides a tremendous security advantage. Soldiers can encounter and see threats without having to themselves be placed at higher risk at the very “tip of the spear.”
However, despite this progress and the growing promise of autonomy, challenges remain when it comes to ruggedizing autonomous vehicles for military missions.
“We have a pretty significant divergence from where commercial industry is going for ground autonomy, a lot of the things that they rely on in terms of fixed infrastructure, well mapped roads, understanding rules of the road and road networks don't necessarily apply,” Mills said.
Ground autonomy has long been recognized as an extremely challenging technological undertaking, given that obstacles or other changes in the environment can require instant, dynamic decision-making. Responding in relation to other moving objects in a fluid, fast-changing environment, can be a challenging task for an autonomous ground vehicle. Autonomy in the air, however, is less complex. Mills explained that these challenges specific to autonomous ground vehicle operation take on a new measure of complexity in combat environments.
“When you start going off-road, in contested environments, and where your enemy gets a vote, you know, you might not have communication, you might not have GPS. I think the place where we're really gonna see autonomy on the ground is being able to expand that operational envelope. Right now we can do it pretty well, when you're in the less contested environments and the off-road terrain isn't too severe,” he added.
Army Ground vehicle autonomy is progressing so quickly and successfully that service engineers, scientists and weapons developers are seeing new horizons of possibility when it comes to generating new tactical advantages.
Advanced algorithms able to operate an entire convoy of 10 or more driverless vehicles are changing the tactical landscape and helping the Army improve and expand ground maneuver operations. If soldiers traveling in a convoy do not have to focus exclusively on driving but are instead transported by advanced Autonomous Navigation Systems built into vehicles, their capacity to perform a wider range of missions with greater effectiveness breaks through to unprecedented levels. An unmanned convoy, for instance, has fewer security requirements, meaning it can operate in hostile areas without the same risks.
“Right now, how we do it in the operational Army is you have to pull from combat units to support the logistic convoys, which really decreases your readiness and pulls folks away from combat missions. As they're forced to run convoy security. If we free up that driving function, now, the logistic units can provide their own security,” Kevin Mills, Deputy Executive Director, Ground Vehicle Intelligent Systems, Army Ground Vehicle Systems Center, told Warrior in an interview.

Where does autonomy go next, now that it has achieved landmark breakthroughs? One of the paradigm-changing elements of this is programming vehicles to recognize vehicle failures and breakdowns well in advance of an actual occurrence. Army weapons developers are now looking at ways to “map out” new avenues of possibility in terms of how advanced new algorithms can perform a wider range of functions beyond just navigation.
“We are working on understanding how, when a vehicle breaks down, and it's unmanned, what do you do? Those are the sorts of ConOps and TTPs that we're learning right now with soldiers, and that's going to enable us to get these systems in the field,” Mills said.
An unmanned or autonomous convoy could, for example, be programmed to respond to specific terrain features, identify and follow certain critical patterns or respond in an advantageous way to unanticipated warfare developments.
“I think we also get the opportunity now to start adding more tactical elements into how so the vehicle isn't just moving from point A to point B, but it's following the way a soldier would make sure you follow a tree line or make sure you don't crest yourself over a hill. Maneuver tactics, which are so essential for warfare, are something that you could program into the machine and we'll see those moving forward as the next level of just getting from point A to point B successfully,” Mills said.
