Virtual Training with RE-LiON

Threat scenarios and capability gaps are evolving faster than training structures can be adapted. At the same time, limited availability of instructors, training areas, systems, and time restricts the necessary repetition at the unit level. The RE-liON Operator Kit—which we encountered at the KSK Symposium 2026—is already in use with the Dutch 13th Infantry Battalion as well as with Ukrainian special forces, providing a portable operational capability infrastructure that can be deployed directly with the unit and kept available for regular training.

The same platform can accommodate a variety of training needs, including firing and operational procedures, positive identification, tactical decision-making, mission planning, and even drone defense. Skills learned in active conflicts, adapted procedures, and new threat scenarios can thus be incorporated into training operations quickly and effectively.

In addition to training weapons, the unit’s own armaments can also be integrated into the system. The training spectrum thus ranges from basic weapons handling to the advancement of complex skills for specialized forces and force-on-force scenarios, and the focus on developing cognitive resilience addresses the demands placed on modern infantry.

Drone defense is a current example of this necessary adaptability within NATO forces. Operators must recognize dynamic flight profiles, prioritize threats, and respond appropriately under time pressure. With the portable kit from RE-liON, changing threat scenarios and the use of various countermeasures can be trained repeatedly and evaluated in detail during an after-action review. Once the system is set up, a 20-minute time window yields up to 15 minutes of active training time. This means units do not need a separate training solution for every conceivable capability gap. Instead, they gain access to a continuously available infrastructure that allows new requirements to be immediately translated into trainable scenarios, robust repetitions, and evaluable results. On September 30, the Operator Kit was showcased at the symposium “Augmented Reality, Virtual Reality, and Mixed Reality in the German Armed Forces” in Idar-Oberstein and generated significant interest.
