Augmented reality is transforming medicine, retail, entertainment, and everyday life — but one of the most dramatic applications yet comes from an entirely different world. Spanish defence and technology company Indra has unveiled an AR glasses system that gives tank crews the ability to effectively see through their own armour, creating a real-time 360-degree view of the battlefield without ever opening a hatch.
What Indra Has Built
Indra is bringing the concept of ‘transparent armour’ to military operations with an advanced system based on augmented reality glasses that allows the wearer to ‘see’ through the vehicle’s armoured structure, thereby enhancing safety and the ability to react to imminent threats.
The concept is elegant in its simplicity. Tanks have always faced a fundamental tension: armour protects the crew, but it also blinds them. Until now, periscopes, viewfinders, or interior screens were used to monitor what was happening outside the vehicle. Now the crew can maintain complete control of the surroundings from inside simply by looking towards the point of interest.
The AR glasses change that entirely. The human-machine interface based on these goggles allows images captured by the vehicle’s cameras to be projected directly into the operator’s field of view, enhanced with information provided by the mission system — the platform’s true ‘brain’.
A 360-Degree Picture, In Real Time
The technology provides a continuous, coherent, real-time 360-degree view. Different sources of information can be integrated into a single panoramic image or distributed across multiple configurable virtual screens, facilitating a comprehensive understanding of the tactical situation. This approach not only improves visibility but also reduces the workload on the crew, who no longer need to interpret fragmented or scattered images.
That last point is as important as the visibility improvement itself. In combat, cognitive load kills. A crew member who has to switch between multiple screens, interpret partial images, and mentally stitch together a picture of what’s outside the vehicle is slower and more error-prone than one who simply looks in the direction they want to see. The AR system removes that translation step entirely.
Tailored to Each Crew Member
The system tailors the information to the role of each crew member — driver, vehicle commander, or gunner — and to the phase of the operation, reducing cognitive load and facilitating decision-making in conditions of fatigue or stress.
A driver needs different information to a gunner. A vehicle commander needs a different view during an advance than during an urban patrol. Indra’s system adapts the AR overlay dynamically, giving each person exactly what they need rather than flooding everyone with the same data.
Why Urban Operations Make This Critical
This technology significantly increases situational awareness and helps to improve the crew’s survival in complex scenarios, such as those encountered during operations in urban areas. In this way, the armour ceases to be a barrier to observation and becomes a protective element without compromising full awareness of the surroundings.
Urban warfare is where armoured vehicles are most vulnerable. Threats can emerge from any direction — above, below, from windows, from alleyways. Traditional periscopes and viewfinders cover only limited arcs of vision. A 360-degree AR system that responds to wherever the crew member looks is a fundamentally different capability in those environments.
The Bigger Strategic Picture
The initiative forms part of Indra’s strategy to develop advanced technologies that will be key to the development of the next generation of main battle tanks in Europe and the modernisation of armoured vehicles already in service. In the coming years, these vehicles will cease to operate in isolation and will instead become nodes within a network, forming a system of systems designed to achieve superiority on the battlefield.
Indra is one of Europe’s largest defence and technology companies, with operations across more than 50 countries. Its involvement in next-generation European tank programmes means this technology has a realistic path to wide deployment across NATO-aligned armies.
What This Tells Us About AR’s Reach
The transparent armour system is a reminder that augmented reality’s most transformative applications aren’t always the ones making headlines in consumer tech. While the industry focuses on smart glasses for everyday wear, researchers and engineers are quietly deploying AR in operating theatres, factory floors, aircraft cockpits, and now the interiors of battle tanks.
The core technology — projecting real-world camera feeds enhanced with contextual data directly into a human operator’s field of view — is the same across all of these applications. What changes is the stakes. In a tank under fire in an urban environment, the difference between seeing and not seeing isn’t a better user experience. It’s survival.
At AugmentedReality.com, our take: This is one of the most compelling AR applications we’ve covered. The “transparent armour” concept sounds like science fiction but the engineering behind it is straightforward — cameras on the outside, AR glasses on the inside, a mission system stitching it all together. What makes it significant isn’t just the military application; it’s the proof of concept for what AR overlays can do in any high-stakes, high-cognitive-load environment. The same principles that help a tank commander see through armour could help a surgeon see through tissue, a firefighter see through smoke, or a pilot see through clouds. Indra has built something genuinely important here — and the fact that it’s being positioned for the next generation of European main battle tanks means it will be deployed at scale. Watch this space.
