Sky-Watch Examines Drone Roles in Hybrid Warfare’s Grey Zones

In the article “The Asymmetry of Hybrid Warfare,” Sky-Watch examines how unmanned systems have transitioned from peripheral tools to central assets within modern conflict scenarios.

The analysis, developed in conversation with PhD fellow and analyst Johan Gröne Christensen, explores operational dynamics within contested spaces where traditional warfare definitions no longer apply.

Operating Between War and Peace

Contemporary conflict increasingly unfolds outside conventional frameworks. Hybrid warfare represents strategic engagement between states or actors pursuing military or political aims through methods that remain beneath recognized thresholds of armed conflict. Within this legal grey area, Unmanned Aerial Systems (UAS) have emerged as particularly effective instruments.

The approach centers not on territorial conquest but on probing state responses, identifying vulnerabilities, and generating uncertainty. Drones contribute significantly to this ambiguity through their lack of identifying markers.

Johan Gröne Christensen, Analyst and PhD Fellow, stated, “Hybrid warfare increasingly blurs the line between war and peace. It’s not always clear when one ends and the other begins.”

This dynamic presents a fundamental challenge: formulating appropriate responses when neither the aggressor nor their objectives can be definitively established.

Unmanned Systems in Contested Spaces

Drones prove exceptionally suited for hybrid operations. Their relatively low cost, mobility, and attribution difficulty make them valuable regardless of whether deployment comes from state actors, non-state groups, commercial platforms, or military-grade systems. The outcome remains consistent across scenarios: operational disruption.

Recent drone incidents above Copenhagen and additional European airports illustrate this principle. While no confirmed damage occurred, the resulting uncertainty triggered widespread disruption, halted air traffic, and redirected both civilian and military resources.

Gröne Christensen continued, “Hybrid warfare is not about taking territory. It’s about creating friction. A drone isn’t just a flying machine. It’s a message.”

In this sense, drones deliver exactly what hybrid actors seek: a high return on investment through ambiguity and risk of escalation.

Non-Kinetic Operations

Hybrid drone deployments rarely emphasize firepower. Primary objectives involve distraction, deterrence, and delay. Consider drones crossing borders during international summits. Even unarmed, they will demand a response. Intelligence must be gathered, leaders briefed, and public narrative shaped. Responding to this type of threat is a complex process. In wartime, rules of engagement are clear. In peacetime, they are not.

Defensive Challenges

The asymmetry becomes evident here. Offensive operations remain inexpensive and adaptable. Defensive measures prove costly and constrained by legal frameworks, political considerations, and public accountability. This imbalance disadvantages states, particularly those slow to adjust operational approaches.

“Yes, you can jam a drone. You can intercept. But doing so in a civilian area, under tight rules of engagement, is not easy,” says Gröne Christensen. “And every time you respond, you expose your own capabilities or lack of them.”

Unmanned platforms also contribute to defensive frameworks. They function not only as aggressors within hybrid warfare but as protective assets. Field-proven intelligence, surveillance, and reconnaissance drones support border patrol operations, monitor infrastructure, and provide decision-makers with enhanced situational awareness.

Interceptor drones add operational flexibility, enabling tracking and neutralization of unauthorized unmanned systems in real time, including urban environments. However, future effectiveness extends beyond hardware alone. It depends on data.

Drones enable persistent ISR capabilities. They monitor troop movements, observe critical infrastructure, or map terrain for subsequent operations. Within hybrid warfare contexts, information frequently holds greater value than kinetic action. This necessitates integrating unmanned systems into broader frameworks, feeding intelligence into real-time analytics, artificial intelligence models, and national security platforms. This integration transforms isolated assets into networked response capabilities, providing defenders with operational advantages in this evolving domain of non-traditional conflict.
