NATO’s Transparent Battlefield: How Polish Special Forces Are Training for a War of Sensors and Drones

Poland is the first foreign NATO ally to take part in this programme, designed by US Army Special Forces under US Special Operations Command Europe. Its significance lies less in the particular infiltration route than in what it says about the alliance’s changing conception of warfare: the rear is no longer a place where troops can expect to be hidden, communications to be secure or movement to go unnoticed.

The lesson comes directly from Ukraine.

The battlefield has become transparent

For decades, Western military planning rested on a powerful assumption: technological superiority, particularly control of the air, could create protected space behind the front line. Special operations forces could penetrate that space, establish communications and coordinate precision fires against targets deeper inside an adversary’s position.

Ukraine has made that model considerably harder to sustain.

Four and a half years of full-scale war have turned drones from relatively simple reconnaissance tools into a central strike capability. FPV systems, modified commercial drones and loitering munitions have extended surveillance and precision attack down to increasingly small tactical formations. Electronic warfare has simultaneously made the electromagnetic spectrum another contested battlespace.

The result is what the exercise calls the “Glass Battlefield”.

A soldier does not need to be physically observed to become vulnerable. A radio transmission, a detectable digital signature, a thermal trace or an exposed movement pattern can provide enough information for an opposing force to locate and engage a unit. A rear area that was once protected by distance can now be penetrated by sensors and cheap airborne systems.

That changes special operations at its foundation.

The Polish teams in Hohenfels must maintain electronic silence, conceal their thermal and digital signatures and move through populated areas without generating the kind of attention that opposing forces can exploit. They may have to remove uniforms or adopt civilian clothing. German residents and local police effectively become part of the surveillance environment because any report can help the opposing force narrow the search.

This is not simply a test of stealth. It is a test of whether a small unit can remain operational while assuming that almost every form of exposure carries consequences.

From assault teams to strike cells

The more consequential change is what the operators are expected to do once they survive the journey.

The exercise ends not with a conventional special-forces assault, but with the deployment of loitering munitions or FPV drones against a simulated high-value command facility. That detail captures the doctrinal shift better than the infiltration scenario itself.

Traditional precision warfare concentrated destructive power in larger formations. A small unit could identify a target, but destroying it might require artillery, aircraft or another centralised fires capability.

Ukraine has demonstrated another model: put enough sensing, targeting and strike capacity directly into the hands of small formations.

The implications are substantial. A special operations team equipped with drones and capable of operating under electronic constraints can potentially find, track and attack a command node without relying on a long chain of requests for external fire support. Precision strike becomes decentralised.

That does not make heavy weapons or conventional air power irrelevant. It does mean that the smallest tactical units increasingly have to behave as independent sensors and strike platforms as well as soldiers.

For NATO, this is a significant departure from the counter-terrorism frameworks that shaped much of the post-Cold War experience of special operations forces. The priority is shifting towards survival against a technologically capable peer adversary.

The exercise is therefore less about teaching Polish troops how to conduct a particular infiltration than about rehearsing an entirely different relationship between the individual soldier, the network and the target.

Poland is an important first mover

The choice of Poland as the first allied participant is difficult to separate from geography.

Poland sits on NATO’s immediate Eastern Flank and has made readiness for a high-intensity conflict a central strategic concern. The exercise also gives other exposed allies an indication of where US special operations training is heading. The programme is expected to be conducted several times a year, with the intention of extending access to most or all of NATO’s 32 members.

The Baltic states, Romania, Finland and Sweden are among the priority candidates.

That matters because the Eastern Flank is where the theoretical problem of the transparent battlefield is most consequential. These states are planning not simply for expeditionary operations or counter-terrorism missions, but for the possibility of confronting Russian military capabilities in an environment saturated with drones, electronic warfare and surveillance.

Poland’s participation also illustrates a broader reality of European defence planning: adaptation is proceeding even as the political future of the American military presence in Europe remains uncertain.

The Trump administration is conducting a global force posture review and has warned of possible US troop reductions in Europe. There have also been changes inside the Pentagon, including the closure of a dedicated Army drone warfare unit.

Yet at the operational level, US and European forces are deepening cooperation around the lessons of Ukraine.

That creates an important distinction. European militaries cannot assume that every element of future American support will remain unchanged, but they can absorb American training, technology and battlefield lessons into their own forces while doing so.

Ukraine becomes part of NATO’s military machinery

The institutional mechanism for that transfer is becoming increasingly important.

The NATO-Ukraine Joint Analysis, Training and Education Centre, or JATEC, in Bydgoszcz, Poland, was established to collect and analyse operational experience from the Ukrainian battlefield and feed it into NATO training and force structures.

The Hohenfels exercise is a practical expression of that process.

For Ukraine, this amounts to more than recognition of its battlefield experience. Tactics developed under the pressure of an actual war are moving into the training architecture of the alliance itself. What was once an improvised adaptation to Russian artillery, armour, drones and electronic warfare can become a standard element of allied preparation.

There is an irony here. NATO spent decades developing sophisticated military systems on the assumption that superior platforms and command networks could dominate the battlespace. Ukraine has shown that relatively small, adaptable technologies can disrupt those assumptions.

The response is not to abandon advanced military systems. It is to distribute capabilities more widely and make formations less dependent on any single vulnerable network.

The procurement problem follows the doctrine

That shift will eventually reach beyond special forces.

If precision effects can increasingly be delivered by inexpensive, rapidly modified drones, conventional procurement models face a difficult question. Large, sophisticated platforms remain valuable, but an army cannot rely exclusively on weapons whose cost, production time and technological architecture make rapid adaptation difficult.

The battlefield in Ukraine has rewarded speed: the ability to modify commercial technology, alter tactics and respond to electronic countermeasures faster than an adversary can adjust.

Institutionalising that advantage is harder.

Commercial and military drone technologies introduce their own operational risks. Systems designed for civilian markets were not necessarily built for the electromagnetic complexity, security requirements or resilience expected in a conventional war. Technologies can become obsolete quickly, while electronic warfare can disrupt systems that appear highly capable under uncontested conditions.

NATO therefore faces a problem that is partly technological and partly organisational. It must learn to procure and train at the speed of a battlefield where yesterday’s successful configuration may already be detectable or vulnerable.

That is why the Hohenfels exercise matters beyond special operations.

The alliance is beginning to train for a war in which concealment is temporary, communications are liabilities as well as assets, and the ability to strike may sit several levels lower in the military hierarchy than it once did.
